I thought I had moved my short SPY calls out far enough to avoid assignment on the ex-date today, but the yesterday’s big 10 point move pushed them too far into the money and nuked all the remaining time premium.

Assigned on 1 SPY 09/27/2024 556 Call and on 1 SPY 09/30/2024 551 Call.

With the stock closing at $570.90 I was looking at a big loss.
Luckily I was able to cover the short stock at $567.97 in the pre-market.
Better, but not great.
