ALNY Covered Call: Strike Selection, Premium & Risk
How to sell covered calls on Alnylam Pharmaceuticals — optimal strikes, expected premium, and the risks that actually matter for a large-cap healthcare name.
Is ALNY a good covered call candidate?
ALNY (Alnylam Pharmaceuticals) is a large-cap healthcare name with an elevated share price and good options liquidity. Implied volatility is high enough to pay meaningful premium without being wild, which is why this ticker shows up frequently in wheel-strategy watchlists. It pays no dividend, so every dollar of income must come from the options you sell.
Strike selection for a ALNY covered call
For ALNY covered calls, target strikes 8-12% out of the money at deltas around 0.15-0.25. Use 21-35 DTE to capture IV without excess gamma risk. On a high-volatility name like ALNY, going closer to the money chases premium at the cost of a much higher assignment probability — the risk of being called away becomes meaningful below 8-12% OTM.
Expected premium and income on ALNY
Typical monthly premium collected on ALNY runs around 2.0-3.5% of capital, which annualizes to roughly 24-42% if you sell new contracts every cycle. Capital required to run a single contract wheel on ALNY is $20,000+ — the share price and the 100-share lot size set the minimum, not the strategy.
Risk management for ALNY covered call trades
The core risk on a covered call is opportunity cost: if the stock rips through your strike, your upside is capped. You still profit, just less than someone who held the shares outright. ALNY's high-volatility profile means 3-6% daily moves are normal during earnings or macro catalysts. 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.
