Re: Pairs Trading UK & US Stocks Journal 
Just thought id post a quick explanation of pair trading to those of you who don't know what it is;
The pairs trade was developed in the late 1980s by quantitative analysts and pioneered by Gerald Bamberger while at Morgan Stanley. With the help of others at Morgan Stanley at the time, including Nunzio Tartaglia, Bamberger found that certain securities, often competitors in the same sector, were correlated in their day-to-day price movements. When the correlation broke down, i.e. one stock traded up while the other traded down, they would sell the outperforming stock and buy the underperforming one, betting that the "spread" between the two would eventually converge.
The pairs trade helps to hedge sector and market risk. For example, if the market as a whole crashes and your two stocks plummet along with it, you should experience a gain on the short position and a negating loss on the long position, leaving your profit close to zero in spite of the large move. In a pairs trade, you are not making a bet on the direction of the stocks in absolute terms, but on the direction of the stocks relative to each other. Pairs trade - Wikipedia, the free encyclopedia |
