Put-selling entry timing — not a quality rating.A strong long-term holding can still show a low score today (thin premium, extended trend, or turning momentum).
Surface indicators and our internal signals diverge — the score reflects the combined read.
Merck is a global pharma giant anchored by Keytruda, its blockbuster oncology franchise. Pays a reliable dividend, low beta (~0.4), defensive. Patent cliff concerns create periodic IV spikes, but overall volatility is low. A textbook defensive CSP name — modest premiums but high probability of success.

⚠️ Single-name concentration. Consider diversifying across multiple tickers — or use a Bull Put Spread to commit less collateral per trade.
Calculator assumptions
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.
