Extract: The report, titled Alternative Thinking: Superstar Investors, was produced by AQR Capital Management, the program-driven investment firm. The researchers compared returns for superstar investors to portfolios it constructed with a small set of buy and sell signals that tracked the investing styles of Mr. Buffett, Mr. Soros and others. It managed to get results that were pretty close to the real thing.
