At the beginning of March, on March 13 to be exact, I sold a put contract against GameStop (GME) with 34 strike and April expiration.
You can read a previous post about this trade in this location.
Today the contract became worthless and I could buy it back for 5 dollars a contract without paying commission for it. I held the contract for 22 days only and I was able to close it 14 days prior to expiration.
Closing the trade now instead of waiting until expiration I could release my maintenance cash, collect my premium and open a new trade instead.
The original trade brought me $81.00 before commissions. By buying it back my profit was $76.00. After commissions I realized 2.29% profit.
