I've traded for many years. About 25 years ago I had an option expire at the money. I didn't know if it would be called away. Back then each trade cost me about $30. per trade (if you can believe it...Full service brokerage). They chose not to exercise the option. An example the option is for $30. and the price close is at $30.
Will it depend on where it is after hours?? What if after hours it doesn't move, or moves up and down then remains ATM? What will happen on the next day (Saturday) at noon?
I know the buyer can exercise, but will they...
Will the MM push the trade forward??
Thanks...Just curious
Ah good old pin risk. https://www.investopedia.com/terms/... is the uncertainty,50-strike would be pinned. There are a lot of price manipulations to push the price one way or another according to this article and it all depends on the open interest of the option.
