PEN Cash-Secured Put: Strike Selection, Premium & Risk
How to sell cash-secured puts on Penumbra Inc. — optimal strikes, expected premium, and the risks that actually matter for a mid-cap healthcare name.
Is PEN a good cash-secured put candidate?
PEN (Penumbra Inc.) is a mid-cap healthcare name with a mid-range share price and fair options liquidity. Implied volatility is moderate — enough premium to make selling options worthwhile, without the heart-stopping price swings you get on speculative names. It pays no dividend, so every dollar of income must come from the options you sell.
Strike selection for a PEN cash-secured put
For PEN cash-secured puts, target strikes 7-10% below the current price at deltas of 0.20-0.30. Use 30-45 DTE — the sweet spot for theta-to-gamma balance. The rule is simple: only sell a put at a strike where you would genuinely be happy owning 100 shares, because on a moderate-volatility ticker you will occasionally get assigned.
Expected premium and income on PEN
Typical monthly premium collected on PEN runs around 1.0-2.0% of capital, which annualizes to roughly 12-24% if you sell new contracts every cycle. Capital required to run a single contract wheel on PEN is $5,000-$20,000 — the share price and the 100-share lot size set the minimum, not the strategy.
Risk management for PEN cash-secured put trades
The core risk on a cash-secured put is assignment into a falling stock: your break-even is the strike minus the premium, so a sharp drop below that level leaves you with unrealized losses on the assigned shares. PEN moves in a moderate-volatility range most of the time, but earnings week and sector rotations can still produce 5%+ single-day prints. Healthcare is exposed to FDA decisions, clinical trial readouts, and policy headlines that can gap the stock overnight. Pharma names need special care around PDUFA dates.
