Empirical evidence suggests that the markets are a non-stationary process- the average return and variance of the returns changes with time. The asset returns of this process are not normally distributed - are you familiar with the 'bell-shaped' curve statistics? Simplistically, there are a greater number of very large positive or negative returns than expected. There are also a larger number of returns clustered in the center of the distribution than expected. Statistical arbitrage and quantitative trading attempt to exploit these (and many, many other) pricing discrepancies. Many methods rely on a long / short position to limit risk. In example, a model might indicate that Ford is underpriced and General Motors overpriced. A quant trader would buy Ford and sell GM in equivalent dollar amounts. It gets even more interesting as you bring foreign assets into the mix - long Swedish bonds and short Danish, or whatever... Hope this helps, Cheers
