Quote from MTE:
Companies can create or destroy value so stocks are not a zero sum game. Options and futures, on the other hand, as it has been pointed out, are contracts between two parties where one party gains at the expense of the other so there's no value creation/destruction merely a re-distribution.
I am not sure I understand it. If the underlying is in a bull market both buyer and seller of the option contract make money. Seller of the contract makes money because he it bought at the lower price. The buyer of the contract is going to make money because he's going to sell it at the higher price.
But the point is that if the underlying is not a ponzi scheme I don't understand how derivitives would be - since I can always in my trading strategy replace underlyings with theire derivitives.
