这个你即使是波音跌了，也只能赚107每手，而理论亏损无限。要做空你就买put。

有了期权费，你还要什么自行车？你买期权挣到钱了吗？

卖期权亏损无上限，最多是赚期权费

没有，我知道欧美的很多期权大神都是纯卖call的，收益也不低。关键是要会止损。现在买期权不划算，时间价值衰减太严重，不涨不跌都相当于吃了个天地板

那意思说你是夸式套利勒？那还有一手买call，那也没问题。

玩期权的高手都是卖期权，而不是买。

有两种方法，一种在低点卖出远期call，那样可以对冲多一点的风险，比如tsla我就是这么操作的，在261买入了一手，同时在263左右以17块一手卖出了一手call（5月3号到期），因为我不认为特斯拉能跌破244。还有一种就是开两个账户，在另一个账户以大于等于正股买入价做空，抵消正股下跌的风险，就是在股价涨到卖出call的行权价的时候要回补空头仓位，这样可以以较低风险赚到call的权利金
