When underlying stock price drop,
its option price should be affected, right?

我没有去查，但记得所有option, put call 的价格都跌。
这个现象在分股时也有。大概只有 sell put/ call 才得益。

这个和分股不一样　　
股票2:1 split    170 call 变成  85 call

去年底很多股票speical dividend   option　strike price被调整了

但是spy dividend不是这样
spy分红  170 put还是170put    这个是确认的  (我之前以为会变成169.14put)

以下是听说的:
short ITM call的会被迫把short call position变成short position  然后付红利
换股票的margin不够 short call position会被强行平仓
long ITM call的没有红利?

有spy call position可以分享一下经历

contr

Are strike prices adjusted to account for regular cash dividends?
No adjustments to strike prices are made when an underlying stock pays an ordinary, regular (e.g., paid quarterly) cash dividend. On the ex-dividend date the underlying stock will open less the dividend amount, but by that point the marketplace will generally have adjusted the prices of calls and puts to account for this.
