HFT allows similar arbitrages using models of greater complexity involving many more than 4 securities.
Like market-making strategies, statistical arbitrage can be applied in all asset classes. Event arbitrage[ edit ] 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 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. Main article: Layering finance 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.
Main article: Quote stuffing 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.
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. 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.
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. However, improvements in productivity brought by algorithmic trading have been opposed by human brokers and traders facing stiff competition from computers.
Cyborg finance[ edit ] 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".
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'.
Lord Myners said the process risked destroying the relationship between an investor and a company. 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.
