无论股票上涨或下跌，保险金都是你的。你当然可以卖掉股票，但那就成了“naked call”

你的风险就变成unlimited。

For example, if you have 100 Tsla shares when it was traded at 200, I buy call option with strike price of 220 from you and give you $20 (ie, you sell covered call at $20)

If you sell Tsla shares before option expires, and Tsla shares jump to 400. Now I come to you and need to buy Tsla from you at 220. You have to go to market and buy it at 400 and sell it at 220 to me
