Again, the explanation for the underperformance is very simple, no conspiracy theories. As Cutten pointed out there is one simple reason: Contango. You will see that this underperformance vanishes when you plot or measure the USO ETF performance vs an investment strategy that rolls over the front month future each momth at random dates in the month that leads to the last trading day
Quote from intradaybill:
I don't think all the points made in the article as correct. I agree there is an issue with front-running but cost in futures trading is not calculated as a percentage of price but it is on a per contract basis. Of course USO may need to buy/sell more contracts to balance the fund but the cost will not rise as much because of front-running. It will certainly increase volatility but will not affect performance that much. IMO the reason of the underperformance is the calculation of contracts needed to rebalance based on fund inflows/outflows rather than on price rise/fall of the underline.
Isn't that simpler than thinking in terms of conspiracies?
