To statistically show skill in investment it takes a whole lot more data than the human mind assumes, so this is a common occurrence in the world of finance. John Paulson, who became famous as one of the fund managers to make a killing shorting mortgage backed securities, lost 50% in a year (much of it to Sino Forrest, a Chinese fraud) a couple years later.
