Futures and foreign exchange are "negative sum transactions". If no new funds enter, the market funds will be sucked away by the handling fee sooner or later. Moreover, if someone loses money in futures and foreign exchange, someone must make money, not to create value, but to redistribute money. No, stocks can create virtual value, which is the so-called company value. All investors can make money, because the so-called company value has increased and the stock price has risen.
