对于options on futures，书上说"Because it costs nothing to enter into a futures contract, the return on a futures contract in a risk-neutral world must be zero. This means we can treat a futures contract like a stock, paying a continuous dividend yield equal to r. This is because when q = r, t he expected growth rate of the stock is zero."，为什么futures没有cost，所以return一定为0呢？
