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.
Intuitive Surgical is the dominant manufacturer of robotic-surgery systems (da Vinci platform), with razor-and-blades revenue from instruments and accessories. Beta around 1.3, no dividend (reinvested in growth). Modest IV most of the time but premiums respond to procedure-volume data and competitor headlines. Premium MedTech wheel — fills a gap that DXCM and IDXX do not cover.

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.
