Stock funds. Stocks are completely traded, that is, you can only buy as many stocks as you have money, while futures is a margin system, that is, you only need to pay 5% to 20% of the turnover to trade 100%. For example, if an investor has 1 10,000 yuan, he can only buy shares of 1 10,000 yuan, and if the investment futures are calculated according to the margin 10%, he can sign a commodity futures contract of 65,438+10,000 yuan, that is to say, he can save money by making small bets.
