In short, a quantum ratio combining mathematical relationship between price and through a trading company or a vehicle for predicting profitable trading opportunities. During 1980, a group of quants working for Morgan Stanley named the gold with a strategy called pairs trading. Institutional investors and members of the investors in the major banks have used the technique since then, and many have made a net profit of the strategy.Tutorial: Guide to Stock Picking StrategiesRarely in the interest of investment bankers and mutual fund managers to share profitable trading strategies with the community, so Pairs Trading remains a secret pro (and a few deft individuals) until the advent of the Internet. Online trading opened the lid on real-time financial information and gives access to beginners for all types of investment strategies. It did not take long for Pairs Trading to attract individual investors and small traders looking for hedging their risk exposure to movements in the broader market.Pairs Trading What Is It?Pairs trading has the potential to achieve profit through relatively simple and low position of risk. Pairs Trading is a market neutral, meaning the overall market direction, does not affect the win or loss.The goal is to match two trading vehicles are highly correlated, trading one long and the other couple's short when prices deviate ratio "x" number of standard deviations - "x" optimized using historical data. If the couple returned to trend, it means that profits made in one or both positions.Example Using StocksTraders can use fundamental or technical data to build Pairs Trading style. Our example here is technical in nature, but some traders use P / E ratio or other fundamental factors to measure correlation and divergence.The first step in designing Pairs Trading is to find two stocks that are highly correlated. Usually this means that businesses in the same industry or sub-sectors, but not always. For example, an index tracking stocks such as QQQQ (Nasdaq 100) or the SPY (S & P 500) can offer an excellent opportunity for Pairs Trading. Two indices that generally trade together are the S & P 500 and Dow Jones Utilities Average.For our example, we'll look at two businesses are highly correlated: GM and Ford.Since both are American car manufacturers, their stocks tend to move together.Below is the weekly chart the price ratio between Ford and GM (calculated by dividing the price of Ford stock by the GM stock price). Price ratio is sometimes called "relative performance" (not to be confused with relative strength index, something completely different). White median line is the ratio of the average price over the last two years. Each yellow stripes and red is the one and two standard deviations from the average ratio.The potential for profit can be identified when the price ratio reaches the first or second deviation. Profitable deviations occurred this is the time to take a long position in the underperformer and a short position in the overachiever. Revenues from short sales to help cover the cost of long positions, making cheap Pairs Trading. Position pairs you have to be matched with the value of the dollar rather than the number of shares, this way, move 5% to be one, even with 5% moves in the other. As with all investments, there is a risk that the trade can move to red, so it is important to determine the stop-loss points before implementing optimized Pairs Trading.Examples of Using Futures Contracts / Futures ContractsPairs Trading strategy works not only with stocks, but also with currencies, commodities and even the option. In the futures markets, "mini" contracts, contracts that represent a small portion of the value of the position of full size, allowing small investors to trade in the future.A Pairs Trading in the futures market may involve arbitrage between futures contracts and cash position of a given index. When getting cash position ahead of the futures contracts, traders may try to profit by memendekken period of time and prolong the index tracking stock, expecting them to come together at some points.Often the time between the index or commodity futures contracts and moves very tight so the only remaining profit to the quickest traders, often using a computer to automatically perform a large position in an instant.Examples Using OptionsOption traders use calls and puts to hedge risks and exploit volatility (or lack thereof). Call (Call) is a commitment by the writer to buy shares at a specified price in the future. Placement (Put) is a commitment by the writer to sell shares at a specified price in the future. A Pairs Trading in the options markets may involve the writing of call for better security than their partners (the other is security related), and matching the position by writing Put, for the pair (underperforming security). When he returned to the second position of the underlying mean them again, the options become worthless allowing the trader to pocket the result of one or both positions.Proof of ProfitabilityIn June 1998, Yale School of Management released a paper written by G. Even Gatev, William Goetzmann, and K. Geert Rouwenhorst who tried to prove that the Pairs Trading profitable. Using 1967-1997 data, the trio found that over a period of six months of trading, pairs trading an average return of 12%. To distinguish profitable results from plain luck, their tests including transaction costs with a conservative estimate and randomly selected pairs.

Fortunately, such strategies couples use market-neutral trading, investors and traders can find profits in all market conditions. Pairs Trading beauty is its simplicity. Relations long / short of two correlated security acts as a ballast for a portfolio that was caught in the choppy waters of the overall market.Good luck with your hunt for profit in Pairs Trading, and this for your success in the marketplace.
