Woolley commented on the results, "If some states allow sports betting and profit by it, other states will want to follow. He announced on May 24, that he planned to go ahead and set up a system of wagering at the state's racetracks and casinos that fall, before the National Football League season ended. In , despite federal law preventions, the state legislature of New Jersey and Governor Chris Christie signed a law that would allow sports betting to take place in New Jersey race tracks and Atlantic City casinos.
Voters were asked whether New Jersey should allow sports betting even if federal law prevents it from doing so, or wait to allow sports betting until federal law permits it. Krista Jenkins, director of the poll, commented, "Although support is not overwhelming, these numbers suggest the public is cautiously behind the goal of moving forward with legalized sports betting.
Purdum, D. Sports betting's growth in U. On June 5, , Delaware became the second state after Nevada to implement full-scale sports betting. Sports betting in the state is run by the Delaware Lottery and is available at the state's three casinos. Prior to , the state offered limited sports betting consisting of parlay betting and championship futures on NFL. Delaware had been granted a partial exemption from the sports betting ban as it had made a failed attempt at legalized sports betting in Phil Murphy signing the legislation into law.
Pennsylvania ,  Rhode Island,  and West Virginia were able to pass legislation legalizing sports betting within their states. Some states must still organize which department will oversee state-regulated sportsbooks, most are choosing between their respective gambling commissions or lottery boards — until then no wagers can be legally taken. Pennsylvania became the seventh state to legalize sports betting when the state had regulations for sports betting in place in August Online sports betting in Pennsylvania began on May 28, when SugarHouse Casino launched an online sports betting app.
On November 21, , Rhode Island became the eighth state to legalize sports betting, with Twin River Casino in Lincoln opening the first sportsbook in the state. In , several states, including Indiana , Iowa , Montana , and Tennessee , legalized sports betting. Indiana and Montana permit brick-and-mortar locations such as casinos but Tennessee restricts sports betting to being online only. The positions of the four major American sports leagues representing American football , baseball , basketball , and ice hockey have become more complex since their decision to embrace daily fantasy sports DFS in , which are described by those within the industry as "almost identical to a casino" in nature.
With the contention by critics that such activities blur the lines between gambling and fantasy sports, the endorsement of all four major sports leagues and many individual franchises provided a marked contrast to their positions on betting. While the National Basketball Association NBA was once active in preventing sports betting law relaxation, current NBA Commissioner Adam Silver became the first major sports leader to break from previous administrative opposition to gambling.
In he stated in a New York Times op-ed, "I believe that sports betting should be brought out of the underground and into the sunlight where it can be appropriately monitored and regulated. Major League Baseball MLB Commissioner Rob Manfred has also advocated the league changing its stance on sports betting, with both Manfred and Silver noting that the scale of illegal sports betting makes opposition to betting meaningless.
He also stated a willingness to "try to shape" any future legislation at federal level. This was noted as a marked contrast to former Commissioner of the MLB Bud Selig , with Manfred going beyond tacit approval and stating, "There is this buzz out there in terms of people feeling that there may be an opportunity here for additional legalized sports betting.
The National Football League NFL remains the only sports league to maintain public opposition to sports betting, however critics have noted that with the move of the Oakland Raiders relocation to Las Vegas in , the NFL has positioned itself for legalization, while simultaneously contradicting its long-held position that sports betting in NFL markets would lead to potential match-fixing.
The NHL was the first major professional league to place a team in Nevada, when the expansion Vegas Golden Knights took the ice in since then the league has signed sponsorship agreements with William Hill and MGM Resorts International that include betting partnerships and access to in-play data.
Other clubs in states with legal sports gambling, such as the New Jersey Devils and Philadelphia Flyers , also have similar sponsorships with bookmakers. Commissioner Don Garber has stated about sports gambling, " We have a project going on now to really dig in deeply and understand it. The American Gaming Association stated in June , that a coalition will advocate for the repeal of the United States' sports betting ban.
In February , a lobbying document surfaced advocating a new position held by the NBA and MLB — that sports leagues should be financially compensated for betting activity. The Football Association , the governing body for association football in England , has imposed football betting bans on all individuals involved in the sport—players, managers, match officials, and club staff. The scope of these bans varies based on level of the English football pyramid.
The following individuals are banned from betting on any football-related matter worldwide, or providing inside information to any individual who can reasonably be assumed to use said information for betting purposes:. Individuals who are associated at clubs at lower levels of the men's or women's league systems, plus match officials at FA Level 4 or below, are only banned with respect to the match or competition in which they are involved or can influence, and also to the league in which they participate.
All individuals are banned from advertising or promoting any football betting activity in which FA regulations prohibit them from engaging. This, however, only applies to individuals in their personal capacities. For example, if a club is sponsored by a betting company and said company places its logo on the club's kit, the team's players are not in violation of the betting rules.
The World Baseball Softball Confederation , the international governing body for baseball and softball , has betting rules similar to those of Major League Baseball. Participants in any WBSC-sanctioned event are banned from betting on the following: . The betting ban, as in the case of The FA's rules outlined above, also extends to providing inside information that the tipper could reasonably believe will be used to bet on a WBSC event. The International Cricket Council imposes a blanket ban on what it calls "corrupt conduct" by anyone it defines as a "participant".
The ICC shares anti-corruption jurisdiction with national cricket federations, all of which have anti-corruption rules substantially identical to those of the ICC. The ICC has elaborate mechanisms for determining whether it or a national federation will take action under the relevant anti-corruption code. In general, the ICC has either exclusive or priority jurisdiction over international matches, while national federations have responsibility for actions relating only to domestic matches.
The ICC code bans the following activities with regard to any international match, whether or not the participant had any involvement in said match, or any possible means of influencing the outcome:. This series would go down as one of the biggest sports scandals of all time. All eight players were banned from playing professional baseball for the rest of their lives. The rule against gambling in baseball is known as "Rule 21," which is publicly posted on dugout walls and states: "Any player, umpire, or club or league official or employee, who shall bet any sum whatsoever on any baseball game in connection with which the bettor has a duty to perform shall be declared permanently ineligible.
For instance, Mickey Mantle and Willie Mays were both banned from baseball in after taking jobs as casino greeters which would have expelled them from the Hall of Fame had it been allowed to stand ; they were reinstated two years later.
Only Rose has yet to be reinstated. A betting scandal between the Massillon Tigers and Canton Bulldogs , two of the top teams in professional American football in the early s, led to the demise of "big-money" professional football for several years. Modern research has suggested that the claims of betting were unsubstantiated. On December 7, the San Francisco 49ers overcame a halftime deficit of 28 points in what became the greatest regular season comeback victory in NFL regular season history.
Rosenthal was able to retain these winnings despite the final outcome of the game due to gambling regulations previously established by the NAGRA. The Cronje Affair was an India-South Africa Cricket match fixing scandal that went public in [ citation needed ] t began in when the-then captain of the South African national cricket team, Hansie Cronje , was convinced by Mukesh "John" Gupta, an Indian bookmaker, to throw a match during a Test in Kanpur, India.
The scheme was discovered when Delhi police recorded illegal dealings between Indian bookmaker Sanjay Chawla and Cronje. Corruption in tennis has been long considered as issue. In and , Koellerer was banned for six months due to his bad behavior. In addition, in August , he facilitated betting by placing odds for matches and had links for placing bets. Machine learning models can make predictions in real time based on data from numerous disparate sources, such as player performance, weather, fan sentiment, etc.

In March , Virtu Financial , a high-frequency trading firm, reported that during five years the firm as a whole was profitable on 1, out of 1, trading days,  losing money just one day, demonstrating the possible benefit of trading thousands to millions of trades every trading day.
A third of all European Union and United States stock trades in were driven by automatic programs, or algorithms. Algorithmic trading and HFT have been the subject of much public debate since the U. Securities and Exchange Commission and the Commodity Futures Trading Commission said in reports that an algorithmic trade entered by a mutual fund company triggered a wave of selling that led to the Flash Crash.
As a result of these events, the Dow Jones Industrial Average suffered its second largest intraday point swing ever to that date, though prices quickly recovered. A July report by the International Organization of Securities Commissions IOSCO , an international body of securities regulators, concluded that while "algorithms and HFT technology have been used by market participants to manage their trading and risk, their usage was also clearly a contributing factor in the flash crash event of May 6, Most retirement savings , such as private pension funds or k and individual retirement accounts in the US, are invested in mutual funds , the most popular of which are index funds which must periodically "rebalance" or adjust their portfolio to match the new prices and market capitalization of the underlying securities in the stock or other index that they track.
Pairs trading or pair trading is a long-short, ideally market-neutral strategy enabling traders to profit from transient discrepancies in relative value of close substitutes. Unlike in the case of classic arbitrage, in case of pairs trading, the law of one price cannot guarantee convergence of prices. This is especially true when the strategy is applied to individual stocks — these imperfect substitutes can in fact diverge indefinitely. In theory the long-short nature of the strategy should make it work regardless of the stock market direction.
In practice, execution risk, persistent and large divergences, as well as a decline in volatility can make this strategy unprofitable for long periods of time e. It belongs to wider categories of statistical arbitrage , convergence trading , and relative value strategies. In finance, delta-neutral describes a portfolio of related financial securities, in which the portfolio value remains unchanged due to small changes in the value of the underlying security.
Such a portfolio typically contains options and their corresponding underlying securities such that positive and negative delta components offset, resulting in the portfolio's value being relatively insensitive to changes in the value of the underlying security. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit at zero cost.
During most trading days these two will develop disparity in the pricing between the two of them. Arbitrage is not simply the act of buying a product in one market and selling it in another for a higher price at some later time. The long and short transactions should ideally occur simultaneously to minimize the exposure to market risk, or the risk that prices may change on one market before both transactions are complete.
In practical terms, this is generally only possible with securities and financial products which can be traded electronically, and even then, when first leg s of the trade is executed, the prices in the other legs may have worsened, locking in a guaranteed loss. Missing one of the legs of the trade and subsequently having to open it at a worse price is called 'execution risk' or more specifically 'leg-in and leg-out risk'. Traders may, for example, find that the price of wheat is lower in agricultural regions than in cities, purchase the good, and transport it to another region to sell at a higher price.
This type of price arbitrage is the most common, but this simple example ignores the cost of transport, storage, risk, and other factors. Where securities are traded on more than one exchange, arbitrage occurs by simultaneously buying in one and selling on the other.
Such simultaneous execution, if perfect substitutes are involved, minimizes capital requirements, but in practice never creates a "self-financing" free position, as many sources incorrectly assume following the theory. As long as there is some difference in the market value and riskiness of the two legs, capital would have to be put up in order to carry the long-short arbitrage position. Mean reversion is a mathematical methodology sometimes used for stock investing, but it can be applied to other processes.
In general terms the idea is that both a stock's high and low prices are temporary, and that a stock's price tends to have an average price over time. An example of a mean-reverting process is the Ornstein-Uhlenbeck stochastic equation. Mean reversion involves first identifying the trading range for a stock, and then computing the average price using analytical techniques as it relates to assets, earnings, etc. When the current market price is less than the average price, the stock is considered attractive for purchase, with the expectation that the price will rise.
When the current market price is above the average price, the market price is expected to fall. In other words, deviations from the average price are expected to revert to the average. The standard deviation of the most recent prices e. Stock reporting services such as Yahoo! Finance, MS Investor, Morningstar, etc. While reporting services provide the averages, identifying the high and low prices for the study period is still necessary.
Scalping is liquidity provision by non-traditional market makers , whereby traders attempt to earn or make the bid-ask spread. This procedure allows for profit for so long as price moves are less than this spread and normally involves establishing and liquidating a position quickly, usually within minutes or less.
A market maker is basically a specialized scalper. The volume a market maker trades is many times more than the average individual scalper and would make use of more sophisticated trading systems and technology. However, registered market makers are bound by exchange rules stipulating their minimum quote obligations.
For instance, NASDAQ requires each market maker to post at least one bid and one ask at some price level, so as to maintain a two-sided market for each stock represented. Most strategies referred to as algorithmic trading as well as algorithmic liquidity-seeking fall into the cost-reduction category. The basic idea is to break down a large order into small orders and place them in the market over time. The choice of algorithm depends on various factors, with the most important being volatility and liquidity of the stock.
For example, for a highly liquid stock, matching a certain percentage of the overall orders of stock called volume inline algorithms is usually a good strategy, but for a highly illiquid stock, algorithms try to match every order that has a favorable price called liquidity-seeking algorithms. The success of these strategies is usually measured by comparing the average price at which the entire order was executed with the average price achieved through a benchmark execution for the same duration.
Usually, the volume-weighted average price is used as the benchmark. At times, the execution price is also compared with the price of the instrument at the time of placing the order. A special class of these algorithms attempts to detect algorithmic or iceberg orders on the other side i. These algorithms are called sniffing algorithms. A typical example is "Stealth". Modern algorithms are often optimally constructed via either static or dynamic programming. Recently, HFT, which comprises a broad set of buy-side as well as market making sell side traders, has become more prominent and controversial.
When several small orders are filled the sharks may have discovered the presence of a large iceberged order. Strategies designed to generate alpha are considered market timing strategies. These types of strategies are designed using a methodology that includes backtesting, forward testing and live testing. Market timing algorithms will typically use technical indicators such as moving averages but can also include pattern recognition logic implemented using Finite State Machines. Backtesting the algorithm is typically the first stage and involves simulating the hypothetical trades through an in-sample data period.
Optimization is performed in order to determine the most optimal inputs. Forward testing the algorithm is the next stage and involves running the algorithm through an out of sample data set to ensure the algorithm performs within backtested expectations.
Live testing is the final stage of development and requires the developer to compare actual live trades with both the backtested and forward tested models. Metrics compared include percent profitable, profit factor, maximum drawdown and average gain per trade.
As noted above, high-frequency trading HFT is a form of algorithmic trading characterized by high turnover and high order-to-trade ratios. Although there is no single definition of HFT, among its key attributes are highly sophisticated algorithms, specialized order types, co-location, very short-term investment horizons, and high cancellation rates for orders.
High-frequency funds started to become especially popular in and Among the major U. There are four key categories of HFT strategies: market-making based on order flow, market-making based on tick data information, event arbitrage and statistical arbitrage.
All portfolio-allocation decisions are made by computerized quantitative models. The success of computerized strategies is largely driven by their ability to simultaneously process volumes of information, something ordinary human traders cannot do. Market making involves placing a limit order to sell or offer above the current market price or a buy limit order or bid below the current price on a regular and continuous basis to capture the bid-ask spread.
Another set of HFT strategies in classical arbitrage strategy might involve several securities such as covered interest rate parity in the foreign exchange market which gives a relation between the prices of a domestic bond, a bond denominated in a foreign currency, the spot price of the currency, and the price of a forward contract on the currency. If the market prices are different enough from those implied in the model to cover transaction cost then four transactions can be made to guarantee a risk-free profit.
HFT allows similar arbitrages using models of greater complexity involving many more than 4 securities. A wide range of statistical arbitrage strategies have been developed whereby trading decisions are made on the basis of deviations from statistically significant relationships. Like market-making strategies, statistical arbitrage can be applied in all asset classes. A subset of risk, merger, convertible, or distressed securities arbitrage that counts on a specific event, such as a contract signing, regulatory approval, judicial decision, etc.
Merger arbitrage also called risk arbitrage would be an example of this. Merger arbitrage generally consists of buying the stock of a company that is the target of a takeover while shorting the stock of the acquiring company. Usually the market price of the target company is less than the price offered by the acquiring company. The spread between these two prices depends mainly on the probability and the timing of the takeover being completed as well as the prevailing level of interest rates.
The bet in a merger arbitrage is that such a spread will eventually be zero, if and when the takeover is completed. The risk is that the deal "breaks" and the spread massively widens. One strategy that some traders have employed, which has been proscribed yet likely continues, is called spoofing. It is the act of placing orders to give the impression of wanting to buy or sell shares, without ever having the intention of letting the order execute to temporarily manipulate the market to buy or sell shares at a more favorable price.
This is done by creating limit orders outside the current bid or ask price to change the reported price to other market participants. The trader can subsequently place trades based on the artificial change in price, then canceling the limit orders before they are executed. The trader then executes a market order for the sale of the shares they wished to sell. The trader subsequently cancels their limit order on the purchase he never had the intention of completing.
Quote stuffing is a tactic employed by malicious traders that involves quickly entering and withdrawing large quantities of orders in an attempt to flood the market, thereby gaining an advantage over slower market participants. HFT firms benefit from proprietary, higher-capacity feeds and the most capable, lowest latency infrastructure.
Researchers showed high-frequency traders are able to profit by the artificially induced latencies and arbitrage opportunities that result from quote stuffing. Network-induced latency, a synonym for delay, measured in one-way delay or round-trip time, is normally defined as how much time it takes for a data packet to travel from one point to another. Joel Hasbrouck and Gideon Saar measure latency based on three components: the time it takes for 1 information to reach the trader, 2 the trader's algorithms to analyze the information, and 3 the generated action to reach the exchange and get implemented.
Low-latency traders depend on ultra-low latency networks. They profit by providing information, such as competing bids and offers, to their algorithms microseconds faster than their competitors. This is due to the evolutionary nature of algorithmic trading strategies — they must be able to adapt and trade intelligently, regardless of market conditions, which involves being flexible enough to withstand a vast array of market scenarios.
Most of the algorithmic strategies are implemented using modern programming languages, although some still implement strategies designed in spreadsheets. Increasingly, the algorithms used by large brokerages and asset managers are written to the FIX Protocol's Algorithmic Trading Definition Language FIXatdl , which allows firms receiving orders to specify exactly how their electronic orders should be expressed.
More complex methods such as Markov chain Monte Carlo have been used to create these models. Algorithmic trading has been shown to substantially improve market liquidity  among other benefits. However, improvements in productivity brought by algorithmic trading have been opposed by human brokers and traders facing stiff competition from computers. Technological advances in finance, particularly those relating to algorithmic trading, has increased financial speed, connectivity, reach, and complexity while simultaneously reducing its humanity.
Computers running software based on complex algorithms have replaced humans in many functions in the financial industry. Finance is essentially becoming an industry where machines and humans share the dominant roles — transforming modern finance into what one scholar has called, "cyborg finance".
While many experts laud the benefits of innovation in computerized algorithmic trading, other analysts have expressed concern with specific aspects of computerized trading. Williams said. But with these systems you pour in a bunch of numbers, and something comes out the other end, and it's not always intuitive or clear why the black box latched onto certain data or relationships. In its annual report the regulator remarked on the great benefits of efficiency that new technology is bringing to the market.
But it also pointed out that 'greater reliance on sophisticated technology and modelling brings with it a greater risk that systems failure can result in business interruption'. UK Treasury minister Lord Myners has warned that companies could become the "playthings" of speculators because of automatic high-frequency trading.
Lord Myners said the process risked destroying the relationship between an investor and a company. Other issues include the technical problem of latency or the delay in getting quotes to traders,  security and the possibility of a complete system breakdown leading to a market crash.
They have more people working in their technology area than people on the trading desk The nature of the markets has changed dramatically. This issue was related to Knight's installation of trading software and resulted in Knight sending numerous erroneous orders in NYSE-listed securities into the market.
This software has been removed from the company's systems. Clients were not negatively affected by the erroneous orders, and the software issue was limited to the routing of certain listed stocks to NYSE. Algorithmic and high-frequency trading were shown to have contributed to volatility during the May 6, Flash Crash,   when the Dow Jones Industrial Average plunged about points only to recover those losses within minutes.
At the time, it was the second largest point swing, 1, And this almost instantaneous information forms a direct feed into other computers which trade on the news. The algorithms do not simply trade on simple news stories but also interpret more difficult to understand news. Some firms are also attempting to automatically assign sentiment deciding if the news is good or bad to news stories so that automated trading can work directly on the news story.
His firm provides both a low latency news feed and news analytics for traders. Passarella also pointed to new academic research being conducted on the degree to which frequent Google searches on various stocks can serve as trading indicators, the potential impact of various phrases and words that may appear in Securities and Exchange Commission statements and the latest wave of online communities devoted to stock trading topics.
So the way conversations get created in a digital society will be used to convert news into trades, as well, Passarella said. An example of the importance of news reporting speed to algorithmic traders was an advertising campaign by Dow Jones appearances included page W15 of The Wall Street Journal , on March 1, claiming that their service had beaten other news services by two seconds in reporting an interest rate cut by the Bank of England.
In late , The UK Government Office for Science initiated a Foresight project investigating the future of computer trading in the financial markets,  led by Dame Clara Furse , ex-CEO of the London Stock Exchange and in September the project published its initial findings in the form of a three-chapter working paper available in three languages, along with 16 additional papers that provide supporting evidence. Released in , the Foresight study acknowledged issues related to periodic illiquidity, new forms of manipulation and potential threats to market stability due to errant algorithms or excessive message traffic.
However, the report was also criticized for adopting "standard pro-HFT arguments" and advisory panel members being linked to the HFT industry. A traditional trading system consists primarily of two blocks — one that receives the market data while the other that sends the order request to the exchange. However, an algorithmic trading system can be broken down into three parts:.
Exchange s provide data to the system, which typically consists of the latest order book, traded volumes, and last traded price LTP of scrip. The server in turn receives the data simultaneously acting as a store for historical database.
The data is analyzed at the application side, where trading strategies are fed from the user and can be viewed on the GUI. Once the order is generated, it is sent to the order management system OMS , which in turn transmits it to the exchange.

Similarly, arbitrage affects the difference in interest rates paid on government bonds issued by the various countries, given the expected depreciation in the currencies relative to each other see interest rate parity. Arbitrage transactions in modern securities markets involve fairly low day-to-day risks, but can face extremely high risk in rare situations,  particularly financial crises , and can lead to bankruptcy.
Formally, arbitrage transactions have negative skew — prices can get a small amount closer but often no closer than 0 , while they can get very far apart. The day-to-day risks are generally small because the transactions involve small differences in price, so an execution failure will generally cause a small loss unless the trade is very big or the price moves rapidly.
The rare case risks are extremely high because these small price differences are converted to large profits via leverage borrowed money , and in the rare event of a large price move, this may yield a large loss. The main day-to-day risk is that part of the transaction fails; this is called execution risk. The main, rare risks are counterparty risk, and liquidity risk: that a counterparty to a large transaction or many transactions fails to pay, or that one is required to post margin and does not have the money to do so.
In the academic literature, the idea that seemingly very low risk arbitrage trades might not be fully exploited because of these risk factors and other considerations is often referred to as limits to arbitrage. Generally, it is impossible to close two or three transactions at the same instant; therefore, there is the possibility that when one part of the deal is closed, a quick shift in prices makes it impossible to close the other at a profitable price.
However, this is not necessarily the case. Many exchanges and inter-dealer brokers allow multi legged trades e. Competition in the marketplace can also create risks during arbitrage transactions. This leaves the arbitrageur in an unhedged risk position. In the s, risk arbitrage was common. In this form of speculation , one trades a security that is clearly undervalued or overvalued, when it is seen that the wrong valuation is about to be corrected.
The standard example is the stock of a company, undervalued in the stock market, which is about to be the object of a takeover bid; the price of the takeover will more truly reflect the value of the company, giving a large profit to those who bought at the current price, if the merger goes through as predicted. Traditionally, arbitrage transactions in the securities markets involve high speed, high volume, and low risk.
At some moment a price difference exists, and the problem is to execute two or three balancing transactions while the difference persists that is, before the other arbitrageurs act. When the transaction involves a delay of weeks or months, as above, it may entail considerable risk if borrowed money is used to magnify the reward through leverage.
One way of reducing this risk is through the illegal use of inside information , and risk arbitrage in leveraged buyouts was associated with some of the famous financial scandals of the s, such as those involving Michael Milken and Ivan Boesky. Another risk occurs if the items being bought and sold are not identical and the arbitrage is conducted under the assumption that the prices of the items are correlated or predictable; this is more narrowly referred to as a convergence trade.
In the extreme case this is merger arbitrage, described below. In comparison to the classical quick arbitrage transaction, such an operation can produce disastrous losses. As arbitrages generally involve future movements of cash, they are subject to counterparty risk : the risk that a counterparty fails to fulfill their side of a transaction. This is a serious problem if one has either a single trade or many related trades with a single counterparty, whose failure thus poses a threat, or in the event of a financial crisis when many counterparties fail.
This hazard is serious because of the large quantities one must trade in order to make a profit on small price differences. Arbitrage trades are necessarily synthetic, leveraged trades, as they involve a short position. If the assets used are not identical so a price divergence makes the trade temporarily lose money , or the margin treatment is not identical, and the trader is accordingly required to post margin faces a margin call , the trader may run out of capital if they run out of cash and cannot borrow more and be forced to sell these assets at a loss even though the trades may be expected to ultimately make money.
In effect, arbitrage traders synthesize a put option on their ability to finance themselves. Prices may diverge during a financial crisis, often termed a " flight to quality "; these are precisely the times when it is hardest for leveraged investors to raise capital due to overall capital constraints , and thus they will lack capital precisely when they need it most. Also known as geographical arbitrage , this is the simplest form of arbitrage.
In spatial arbitrage, an arbitrageur looks for price differences between geographically separate markets. For whatever reason, the two dealers have not spotted the difference in the prices, but the arbitrageur does. The arbitrageur immediately buys the bond from the Virginia dealer and sells it to the Washington dealer. Usually, the market price of the target company is less than the price offered by the acquiring company.
The spread between these two prices depends mainly on the probability and the timing of the takeover being completed as well as the prevailing level of interest rates. The bet in a merger arbitrage is that such a spread will eventually be zero, if and when the takeover is completed. The risk is that the deal "breaks" and the spread massively widens. Also called municipal bond relative value arbitrage , municipal arbitrage , or just muni arb , this hedge fund strategy involves one of two approaches.
The term "arbitrage" is also used in the context of the Income Tax Regulations governing the investment of proceeds of municipal bonds; these regulations, aimed at the issuers or beneficiaries of tax-exempt municipal bonds, are different and, instead, attempt to remove the issuer's ability to arbitrage between the low tax-exempt rate and a taxable investment rate.
Generally, managers seek relative value opportunities by being both long and short municipal bonds with a duration-neutral book. The relative value trades may be between different issuers, different bonds issued by the same entity, or capital structure trades referencing the same asset in the case of revenue bonds. Managers aim to capture the inefficiencies arising from the heavy participation of non-economic investors i. There are additional inefficiencies arising from the highly fragmented nature of the municipal bond market which has two million outstanding issues and 50, issuers, in contrast to the Treasury market which has issues and a single issuer.
Second, managers construct leveraged portfolios of AAA- or AA-rated tax-exempt municipal bonds with the duration risk hedged by shorting the appropriate ratio of taxable corporate bonds. The steeper slope of the municipal yield curve allows participants to collect more after-tax income from the municipal bond portfolio than is spent on the interest rate swap; the carry is greater than the hedge expense.
Positive, tax-free carry from muni arb can reach into the double digits. The bet in this municipal bond arbitrage is that, over a longer period of time, two similar instruments—municipal bonds and interest rate swaps—will correlate with each other; they are both very high quality credits, have the same maturity and are denominated in the same currency.
Credit risk and duration risk are largely eliminated in this strategy. However, basis risk arises from use of an imperfect hedge, which results in significant, but range-bound principal volatility. The end goal is to limit this principal volatility, eliminating its relevance over time as the high, consistent, tax-free cash flow accumulates.
Since the inefficiency is related to government tax policy, and hence is structural in nature, it has not been arbitraged away. A convertible bond is a bond that an investor can return to the issuing company in exchange for a predetermined number of shares in the company. A convertible bond can be thought of as a corporate bond with a stock call option attached to it. Given the complexity of the calculations involved and the convoluted structure that a convertible bond can have, an arbitrageur often relies on sophisticated quantitative models in order to identify bonds that are trading cheap versus their theoretical value.
Convertible arbitrage consists of buying a convertible bond and hedging two of the three factors in order to gain exposure to the third factor at a very attractive price. For instance an arbitrageur would first buy a convertible bond, then sell fixed income securities or interest rate futures to hedge the interest rate exposure and buy some credit protection to hedge the risk of credit deterioration. Eventually what he'd be left with is something similar to a call option on the underlying stock, acquired at a very low price.
He could then make money either selling some of the more expensive options that are openly traded in the market or delta hedging his exposure to the underlying shares. A depositary receipt is a security that is offered as a "tracking stock" on another foreign market. For instance, a Chinese company wishing to raise more money may issue a depository receipt on the New York Stock Exchange , as the amount of capital on the local exchanges is limited. These securities, known as ADRs American depositary receipt or GDRs global depository receipt depending on where they are issued, are typically considered "foreign" and therefore trade at a lower value when first released.
Many ADR's are exchangeable into the original security known as fungibility and actually have the same value. In this case, there is a spread between the perceived value and real value, which can be extracted. Other ADR's that are not exchangeable often have much larger spreads. Since the ADR is trading at a value lower than what it is worth, one can purchase the ADR and expect to make money as its value converges on the original. However, there is a chance that the original stock will fall in value too, so by shorting it one can hedge that risk.
Some brokers in Germany do not offer access to the U. In most cases, the quotation on the local exchanges is done electronically by high-frequency traders , taking into consideration the home price of the stock and the exchange rate. This kind of high-frequency trading benefits the public as it reduces the cost to the German investor and enables him to buy U.
A dual-listed company DLC structure involves two companies incorporated in different countries contractually agreeing to operate their businesses as if they were a single enterprise, while retaining their separate legal identity and existing stock exchange listings. In integrated and efficient financial markets, stock prices of the twin pair should move in lockstep. In practice, DLC share prices exhibit large deviations from theoretical parity.
Arbitrage positions in DLCs can be set up by obtaining a long position in the relatively underpriced part of the DLC and a short position in the relatively overpriced part. Such arbitrage strategies start paying off as soon as the relative prices of the two DLC stocks converge toward theoretical parity. However, since there is no identifiable date at which DLC prices will converge, arbitrage positions sometimes have to be kept open for considerable periods of time.
In the meantime, the price gap might widen. In these situations, arbitrageurs may receive margin calls , after which they would most likely be forced to liquidate part of the position at a highly unfavorable moment and suffer a loss. Arbitrage in DLCs may be profitable, but is also very risky. Lowenstein  describes that LTCM established an arbitrage position in Royal Dutch Shell in the summer of , when Royal Dutch traded at an 8 to 10 percent premium.
In the autumn of , large defaults on Russian debt created significant losses for the hedge fund and LTCM had to unwind several positions. Lowenstein reports that the premium of Royal Dutch had increased to about 22 percent and LTCM had to close the position and incur a loss.
According to Lowenstein p. See further under Limits to arbitrage. Thus, if a publicly traded company specialises in the acquisition of privately held companies, from a per-share perspective there is a gain with every acquisition that falls within these guidelines. Private to public equities arbitrage is a term that can arguably be applied to investment banking in general. Private markets to public markets differences may also help explain the overnight windfall gains enjoyed by principals of companies that just did an initial public offering IPO.
Regulatory arbitrage "is an avoidance strategy of regulation that is exercised as a result of a regulatory inconsistency". On the other hand, if the real risk is higher than the regulatory risk then it is profitable to make that loan and hold on to it, provided it is priced appropriately. Regulatory arbitrage can result in parts of entire businesses being unregulated as a result of the arbitrage. This process can increase the overall riskiness of institutions under a risk insensitive regulatory regime, as described by Alan Greenspan in his October speech on The Role of Capital in Optimal Banking Supervision and Regulation.
The term "Regulatory Arbitrage" was used for the first time in when it was applied by Scott V. Simpson, a partner at law firm Skadden, Arps, to refer to a new defence tactic in hostile mergers and acquisitions where differing takeover regimes in deals involving multi-jurisdictions are exploited to the advantage of a target company under threat. In economics, regulatory arbitrage sometimes, tax arbitrage may refer to situations when a company can choose a nominal place of business with a regulatory, legal or tax regime with lower costs.
This can occur particularly where the business transaction has no obvious physical location. In the case of many financial products, it may be unclear "where" the transaction occurs. Regulatory arbitrage can include restructuring a bank by outsourcing services such as IT. The outsourcing company takes over the installations, buying out the bank's assets and charges a periodic service fee back to the bank.
This frees up cashflow usable for new lending by the bank. The bank will have higher IT costs, but counts on the multiplier effect of money creation and the interest rate spread to make it a profitable exercise. The bank can often lend and securitize the loan to the IT services company to cover the acquisition cost of the IT installations. This can be at preferential rates, as the sole client using the IT installation is the bank. The IT services company is free to leverage their balance sheet as aggressively as they and their banker agree to.
This is the reason behind the trend towards outsourcing in the financial sector. Without this money creation benefit, it is actually more expensive to outsource the IT operations as the outsourcing adds a layer of management and increases overhead. According to PBS Frontline's four-part documentary, "Money, Power, and Wall Street," regulatory arbitrage, along with asymmetric bank lobbying in Washington and abroad, allowed investment banks in the pre- and post period to continue to skirt laws and engage in the risky proprietary trading of opaque derivatives, swaps, and other credit-based instruments invented to circumvent legal restrictions at the expense of clients, government, and publics.
These programs that have similar characteristics as insurance products to the employee, but have radically different cost structures, resulting in significant expense reductions for employers. Telecom arbitrage companies allow phone users to make international calls for free through certain access numbers. Miller calls Jimmy Grant Nate Parker , the son of his late chauffeur, who feels loyal to Miller for paying his father's medical bills.
After Jimmy drives him home, Miller removes security camera DVDs that show his late arrival, burns his bloody clothing, then goes to bed bruised at am, arousing wife Ellen's Susan Sarandon suspicion. The next day, Miller discusses his "hypothetical" situation with his lawyer Stuart Margolin , who advises the hypothetical person to turn themselves in, as the lies required to keep the story a secret will pile up.
The lawyer also mentions that Ellen has visited an estate lawyer. Miller is later questioned by police detective Bryer Tim Roth , who is keen on arresting him for manslaughter. Meanwhile, Brooke discovers Miller's fraud and, realizing that she could be implicated, confronts him.
Miller admits to the fraud, but insists that he will handle it. Jimmy is arrested and placed before a grand jury , but still refuses to admit to helping Miller cover up the accident. Miller once again contemplates turning himself in. Even though Jimmy is about to go to prison, Miller tells him that investors are depending on him and that waiting for the sale to close before coming forward would serve the greater good.
Eventually, Miller gets himself and Jimmy out of trouble by proving that Bryer fabricated evidence. With the audit complete and the company in the clear for the sale, Miller meets Mayfield and they agree on a price. Later, Ellen confronts Miller and offers him a deal: if he signs a separation agreement that gives all voting rights and money to her non-profit foundation and their daughter, she will lie and say she was with him the night of the accident; if he refuses, she will tell the truth and he will go to prison.
Meanwhile, Mayfield discusses a secondary audit that has been performed on Miller's company. The report does show a problem, but Mayfield chooses to ignore it and go forward with the sale. In the final scene, Miller addresses a banquet honoring him, with Ellen at his side and Brooke introducing him. However, both Brooke's cold embrace and Ellen's angry expression contrast Miller's confident demeanor.
Miller has not been intimidated by Ellen's attempt at blackmail. She knows as well as he does that the contract she had drawn up would make her just as liable to criminal charges if the police discovered the truth. Smiling as he approaches the podium to deliver his speech, the screen cuts to black.
