MSTR — at 22.8% below its 200-day average, mean-reversion sits inside the typical CSP window. Under that condition, the 200-day reference is a more relevant strike anchor than current price.
Cash-secured puts require holding cash equal to strike × 100 shares as collateral. Strike defaults to ~5% OTM, snapped to typical exchange increments. Premium defaults to ~2% of strike — adjust to your real expected fill. Annualized ROC = (premium ÷ collateral) × (365 ÷ DTE). CSP risk is single-name concentration: experienced put-sellers typically diversify across 4–6 underlyings rather than committing the whole account to one ticker. Continuous-rolling projections assume capital can be re-deployed after each expiration and that comparable premiums remain available — actual results vary with market conditions, assignments, and rolls.
