PuppBaby, I know you don't care, but here you go: you Sold to Open (STO) a Cash Secured Put (STO-CSP), but I think we all understood you.PuppBaby wrote: ↑Wed May 11, 2022 3:33 pm I did my 1st Sell to Own Put option. Got in Affirm the other day at $18 Put for $1.5 to open expiring 5/13? Idk if I'm wording this clearly, please let me know how it should be said so I'm clearer in the future. Anyway currently its trading at just about $16.5. I'm assuming come Friday I will own the stock if its below 16.5? What if its not do I still own the stock but at $16.5?
You may or may not get assigned even if it drops below $16.50 since that exact option could have been bought at a higher premium (you just don't know) just as Yodean mentions. The option could expire or you get shares assigned (shares Put to you); you won't know until Monday (I think if not sooner).
When you sell puts, you expect (at some point) that the price will increase, but during the period between the time I sell one and expiration, I like to monitor the option price/premium. If the price of the security rises, the value of the premium will decrease (time and volatility also have an effect on premium price; what you paid will not change which was your to keep no matter what). Unless I have no other choice (in your example as of this writing the premium for the same option is $4.00), I like to (not always) buy back (Buy to Close) the option by or on expiration, which can be a very small premium (pennies). I like to keep house, so to speak and prefer not to just let it expire. Your preference, but I like to ensure I am closing and monitoring all options that I do.
