定义

蝶式差价期权是一种多腿期权策略,涉及同时购买和出售不同执行价的看涨期权和看跌期权。它创造了一个类似蝴蝶形状的损益图,因此得名。

组成

蝶式差价期权由以下四部分组成:

  • 看涨期权买入:在中间执行价购买一份看涨期权。
  • 看涨期权卖出:在比中间执行价略高的执行价上出售一份看涨期权。
  • 看跌期权卖出:在比中间执行价略低的执行价上出售一份看跌期权。
  • 看跌期权买入:在最低执行价上购买一份看跌期权。

运作原理

蝶式差价期权利用期权价格的波动来获利。当标的资产价格在中间执行价附近波动时,蝶式差价期权的损益图呈现出蝴蝶形状。

  • 上涨趋势:如果标的资产价格上涨,中间执行价的看涨期权将升值,而其他期权将贬值。这将导致损益图的右侧向上倾斜。
  • 下跌趋势:如果标的资产价格下跌,中间执行价的看跌期权将升值,而其他期权将贬值。这将导致损益图的左侧向上倾斜。
  • 盘整趋势:如果标的资产价格在中间执行价附近盘整,所有期权的价值都将下降。这将导致损益图的中间区域呈下凹状。

损益图

蝶式差价期权的损益图通常如下所示:
