Quantitative Trading

Just the numbers. Quant traders try to find arbitrage-like opportunities wherein some bundle of options, combined, is mispriced relative to buying an underlying series of stocks, or some other related group of assets. Then they wait. And supposedly, over time, the "right" prices reach the endpoint and the traders make money.

It doesn't always work out. See: Long-Term Capital Management. See: Fundamental Analysis, too, because quant traders barely even know what this discipine is. They often can't read an income statement, much less really understand how the companies they're trading in even make money. Wall Street seems to always fall in love with algorithms and black boxes to trade for them...and they work. Until they don't. And then they don't...badly. See the movie Frankenstein for details.
