Earnings play on nvda with the help of iv crush.

On nov 18 /24, Sold csp at strike 120, 31 dte dec 20 /24, premium 202, delta -0.156, iv 56%, Annualised Return 19.82%. The iv has inflated  to 120%, Nvda at 147 now, up $7. I have collected 48% of the premium now. Infact i can even close it today because have collected close to 50% in 1 day. Normally I would do 2 or 3 dte expire this Friday, since i didn't want to take too much risk so i just go out 31 dte. You can still benefit from the iv crush effect. Beginners always get the misconception that, selling csp short period is better because  they want faster theta or time decay. The thing is, alot of times i will go out 45 to 100 dte, it doesn't really mean i will hold that long to collect the full premium. I prefer to go out longer because it's alot easier to manage the trade when it go against you.
