$Facebook(FB)$请问，如果溢价率高于多少会有什么不好的影响？？正股开盘昨晚下跌18%买了100美元的call期权

但是开盘没多久就跌到19%，亏损40%，然后曾经回到正股下跌18%时候的价格，依然亏损25%就平仓了

请问为什么不是应该赚回40%到我之前买的价格的位置吗？

期权隐含波动率了解下，时间价值在减少

  谢谢解答，看来是时间价值没多少，所以越来越不值钱了

下跌的时候真的不应该买call期权，感觉时间价值这块都先输了一半了

我在正股下跌18%时候买了的call期权100美元，跌到19%，亏损50%只值50美元

中午正股回到下跌18%的时候，依然亏了30%.就只剩70美元左右，根本没有回到原来我的本金水平，其中30美元消失不见了

正股下跌的时候call期权最不值钱了
