Guess it depends on what is meant by sophisticated. complex or intricate, as a system, process, piece of machinery, or the like: a sophisticated electronic control system. dictionary.reference.com I'd call Buffet and similar folks rigorous. Not sophisticated. This is what I'd call sophisticated: For over two decades, Simons' Renaissance Technologies hedge fund, which trades in markets around the world, has employed complex mathematical models to analyze and execute trades--many of them automated. Renaissance uses computer-based models to predict price changes in easily-traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions. Renaissance employs many specialists with non-financial backgrounds, including mathematicians, physicists, astrophysicists and statisticians. Renaissance's quantitative trading model trades at such high frequency that it (the Nova fund, specifically) occasionally accounts for over 10% of all the trades occurring on NASDAQ. en.wikipedia.org The ultimate black box investor.
