Quote from Hyudra:
oh they aren't... plz do explain. At least trading I would think is zero-sum.
Quote from Steve Tvardek:
Zero sum assumes 1 loses and 1 wins. But in equties, you could have bought shares from someone who made a gain themselves and you may sell shares to someone else at a higher price and then may do the same etc etc.
In futures, the game is zero sum, since 1 of you will be right and the other wrong.
Quote from Hyudra:
Ya, that is one way to think about it, but what if say in trading, you and the market knows that XYZ is worth $25. If you sell at prices higher than $25, you are essentially taking advantage of someone else. You won and the other trader lost, because he was uninformed that the price of XYZ was $25.
