Short four calls at a strike that you’re targeting.
.
I purchased them at 286, so my targeted strike price is 286. As long as SPY is below 286, I keep the premium from writing the calls. However, suppose SPY opens on the day of expiration at 300, then my 200 shares will be called away at the end of the day, which is fine because I have already made money selling two calls. But I will lose money on two other calls, so I will have to buy stock at 300 and sell it at 286. I also won't be able to buy back the two calls I sold because now they're in the money, and hence more expensive to buy them back. Is my reasoning correct?
