STM Covered Call: Strike Selection, Premium & Risk
How to sell covered calls on STMicroelectronics NV — optimal strikes, expected premium, and the risks that actually matter for a large-cap technology name.
Is STM a good covered call candidate?
STM (STMicroelectronics NV) is a large-cap technology name with a low share price and good 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 also pays a dividend, which adds a second income stream on top of the premium you collect.
Strike selection for a STM covered call
For STM covered calls, target strikes 5-8% out of the money at deltas around 0.20-0.30. Use 30-45 DTE — the sweet spot for theta-to-gamma balance. On a moderate-volatility name like STM, 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 5-8% OTM.
Expected premium and income on STM
Typical monthly premium collected on STM 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 STM is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.
Risk management for STM 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. STM moves in a moderate-volatility range most of the time, but earnings week and sector rotations can still produce 5%+ single-day prints. Tech names are especially vulnerable to interest-rate shifts and earnings guidance revisions — both tend to produce gap moves that hurt short options.
