A few weeks ago I learned the Exercise Cut-Off Time for Expiring Options is an additional 90 minutes after markets close.

Ment to share this a few weeks ago.

Wish I knew that option buyers had until 5:30 PM EST to exercise their options.

I had HOOD $105 Covered Call for 9/5/2025.

The announcement that Robinhood (HOOD) was added to the S&P 500 was made by S&P Dow Jones Indices on Friday, September 5, 2025.

Robinhood went from roughly $101 at market close to about $110 in after market hours.

Lost my shares, and it hurt.

Just sharing this to help anyone else that may not know this rule. You can verify and read more here -> https://www.finra.org/rules-guidance/notices/information-notice-020321
