Unlike the options and futures markets, the stock market is not a zero sum game. It is very possible for all investors in the stock market to make money, or for all to lose money. On fact, over the long term the majority of investors in the stock market make money. Note that I said INVESTORS not TRADERS.
No ALL financial markets are zero-sum games. If those investors made money in the stock market, somewhere, someone, at some time lost money.
