About the same time, hedge fund manager Michael Masters reached the same conclusion. Masters' expertise is in tracking the flow of investments into and out of financial markets and he noticed huge amounts of money leaving stocks for commodities and oil futures, most of it going into index funds, betting the price of oil was going to go up.
Asked who was buying this "paper oil," Masters told Kroft, "The California pension fund. Harvard Endowment. Lots of large institutional investors. And, by the way, other investors, hedge funds, Wall Street trading desks were following right behind them, putting money - sovereign wealth funds were putting money in the futures markets as well. So you had all these investors putting money in the futures markets. And that was driving the price up."
