My ownership of a stock is a claim on a portion of a company’s assets and future productive addition to the economy. The stock market is a positive sum game. If I buy a share of ABC Gold mining company, it’s because I expect them to dig some actual gold out of the ground and expanding the economy. They can distribute a dividend to me after then selling that gold. No one has added any money to the stock market, but I am wealthier.
