跨式期权组合的中文解释

指一种包含相同的行使价和到期日的看涨期权和看跌期权的期权策略。这种策略通过在市场上涨时履行看涨期权，而在下跌时履行看跌期权，而使期权的购买者享受价格波动较大的好处。风险是如果价格只小幅波动，价格的变化过小，无法抵偿购买两份期权的成本。

Straddle的英文解释

An option strategy involving one call and one put with the same strike and same expiry date. The strategy allows the buyer to take advantage of large price movements in either direction, by exercising the call in a rising market and the put in a falling market. The risk is that prices move only slightly and the change is not enough to cover the costs of the two options.
