摘要

In an interview, David Leinweber, UC Berkeley professor, talked about who was to blame for Wall Street's meltdown and what the future holds for quantitative analysts. According to Leinweber, the stock side of Wall Street is pretty simple by comparison to more complex financial instruments. These people built a mathematical house of cards. He said that quants were responsible on some level for the market meltdown. There were no position limits; you could make as much of it as you wanted. For instance, there are only so many stocks of Apple you can buy. With mortgage-backed securities, you could just keep making them. A huge volume of the trading going on in options and stock markets is being done through market-making trading. These are firms that on any given day are doing 20% of the market in equities, and that's all automated.
