股指期货，全称为股票价格指数期货，是一种以股票指数为标的物的金融衍生品。而在这其中，“期货”一词是关键。那么，期货究竟是什么呢？

中文内容：

期货是一种金融衍生品，其交易方式与现货交易不同。在期货交易中，买卖双方通过签订标准化合约的方式，约定在未来某一特定时间以特定价格交割一定数量的标的物。这种合约具有杠杆效应，允许小额资金进行大额交易，并且交易成本相对较低。期货市场是一个高度规范化的市场，由交易所统一管理和监管。期货交易的主要目的是为了规避价格风险、发现价格和进行套期保值等。

Futures are a type of financial derivative that differ from spot transactions in their trading methods. In futures trading, buyers and sellers enter into standardized contracts that specify the delivery of a certain quantity of the underlying asset at a specific price at a future date. These contracts have leverage, allowing small amounts of capital to engage in large-scale transactions, and have relatively low transaction costs. The futures market is a highly standardized market, with exchanges providing centralized management and supervision. The main purposes of futures trading include hedging price risk, price discovery, and portfolio diversification.
