为什么期货是杠杆？

期货是一种金融衍生品，它允许投资者通过交易期货合约来对未来商品价格变动进行投机或者对现有的现货风险进行对冲。期货之所以被视为杠杆，是因为投资者只需要缴纳合约价值的一定比例作为保证金，就可以控制相当于保证金几倍甚至几十倍的合约价值。

英文翻译对照：Why is futures a leverage?

Futures are derivative financial instruments that allow investors to speculate on future commodity price movements or hedge existing spot risks. Futures are considered leverage because investors only need to pay a certain proportion of the contract value as margin to control a contract value several times or even dozens of times greater than the margin.

期货市场的杠杆效应给投资者带来了高收益和高风险。当市场行情有利于投资者时，投资者可以获得合约价值几倍甚至几十倍的收益。然而，如果市场行情不利，投资者可能会损失比他们最初支付的保证金更多的资金。因此，期货市场的杠杆效应是一种双刃剑，既带来了高收益的可能性，也带来了高风险的挑战。

英文翻译对照：The leverage effect of the futures market brings high returns and high risks to investors. When the market trend is favorable for investors, they can obtain returns several times or even dozens of times greater than the margin they initially paid. However, if the market trend is unfavorable, investors may lose more money than their initial margin payment. Therefore, the leverage effect of the futures market is a double-edged sword, which brings both high return possibilities and high risk challenges.
