overvaluation, still, on current oil price)… Hedge funds have been a massive force amplifying the positive uptrend in commodity prices. At the peak of the commodity cycle, they held more than 17% of the most liquid of them, the oil market.”

“Based upon its investigation into the role of market speculation in rising oil and gas prices, the Subcommittee staff makes the following findings and recommendations.
A. Findings
1. Rise in Speculation. Over the past few years speculators have expended tens of billions of dollars in U.S. energy commodity markets.
2. Speculation Has Increased Prices. Speculation has contributed to rising U.S. energy prices, but gaps in available market data currently impede analysis of the specific amount of speculation, the commodity trades involved, the markets affected, and the extent of price
impacts.”
