$蔚来(NIO)$ 我有一个关于期权的问题，假设有一个股票现价50，我卖了一个60的看涨期权。然后这个股票涨到了55，如果我预测这个股票要大涨，假设这个股票真的要大涨，我现在立刻亏一点买入60的看涨期权，是不是相当于我把先前的做空的60看涨期权平仓了？

永远不要干卖call和put的事，理论上赔起来没有上限

是的
- 飞天小黄鸡:
  多谢，明白了👌
- 静静的百合May回复飞天小黄鸡:
  到期可以以行权价格卖券（如果你持有正股）。没正股的话如果股价持续上涨你保证金不够了不用等到到期就爆仓了，所以一般不建议裸卖call
- 飞天小黄鸡:
  那做空看涨期权是不是不平仓就得到期自动平仓？
