Closed 17 MU $500 CSPs at 43% max profit ($61K realized) in 16% of the time, thanks to IV crush

Closed my 17 MU $500 6/27 CSPs today at $47.50 against a blended cost of approx $83.24, capturing approx $60,750, or 43% of the $141,508 max profit. Sold in three tranches: 5/20 at $93.54 with MU at approx $732, 7/10 at $65.95 with MU at approx $979, and 7/20 at $74.99 with MU at approx $865. Held roughly 16% of the position’s total life on a contract-weighted basis, so the return per unit of time came in at about 2.7x linear. Never came within $200 of the strike.

That was the design. Strike set far enough out that Monte Carlo put assignment odds under 5%, then let vol do the work: sell into the rerating pandemonium when IV was in the 90s and MU was repricing from the low hundreds toward $1,255, and close once the percentage of max profit captured exceeds the percentage of time held. With vega at 1.60 against delta of only -0.12, the vol move did roughly 13x the work per unit that direction did. IV bled to 75.8% and then into the mid-40s bid, and the remaining $47.50 would have needed approx 10 more months of collateral and 3 to 4 more earnings prints at approx 12% annualized. Freeing the collateral now means I can re-enter the same structure if and when vol shoots up again, or write CSPs on another stock I monitor. I still hold 1,350 shares, so full upside either way.

\*note: CSP means cash secured put, not naked put.

\*MU positions: 1,350 long shares, looking to accumulate more if price is right
