根据咨询公司的数据，随着市场波动性的上升和中国衍生品市场的发展，中国的上市公司热衷利用衍生工具对冲风险。请看本报周四的报道：

Listed firms in China are embracing hedging at a record pace, according to consultancy data, as market volatility rises and China grows its derivative market.

During the April-June period, more than 120 China-listed companies in non-financial sectors unveiled plans for the first time to hedge risk using tools such as options and futures, the most for any quarter.

报道中的hedging就是“对冲”，常见的工具有option (期权)和futures (期货)；期权分为call option (看涨期权)和put option (看跌期权)。
