Algorithms Prove No Match For Market Tumble

from the all-in-the-data dept

Earlier this year, famed inventor (among other things) Ray Kurzweil announced that he was getting set to launch a new investment company that would employ advanced mathematical techniques to discern patterns in the stock market. Of course, just because Kurzweil is widely considered to be a genius, it doesn't mean he'd have any midas touch when it comes to the stock market. Furthermore, quant funds, as they're known, aren't novel. Lately, in fact, they've been getting slaughtered as the market swings about in unpredictable ways. Top tier investment bank Goldman Sachs has announced that its closing one of its premier quant funds in light of recent losses. Obviously computers have become an indispensable tools in modern day investing, but no algorithm or mathematical genius can guarantee good performance in all markets.

    Re: The problem is in the details

    One possible reason these mathematical models fail in actual markets is in the assumptions made. One of the fundamental assumptions in the Black-Scholes market model is that stocks are normally distributed

    I understand one of the problems LTCM got into was that the model assumed that the market would stay liquid at all times. This was the same assumption the portfolio insurance schemes made in 1987 - with the same result when the assumption turned out to be untrue.
