Covered Call: Generating Monthly Income on Stocks You Own
A covered call sells one short call against 100 shares of stock you own. You collect premium today; in exchange, you cap your upside at the call's strike. If the stock stays below strike, you keep the premium and the shares. If it rallies past strike, your shares are called away at the strike — a profit, just a capped one.
The economics: covered calls on quality stocks at the 0.20–0.30 delta strike, 30–45 DTE, typically generate 1–2% monthly premium yield (12–24% annualized). That income is incremental on top of dividends and stock appreciation up to the strike. The strategy underperforms outright stock ownership in raging bull markets and outperforms in flat to modestly bullish markets. Across decades, the historical return profile of buy-write strategies (buying stock + writing covered calls) has rivaled buy-and-hold with lower volatility.
Common mistakes: selling covered calls below your cost basis (forces a realized loss if assigned), selling too aggressively in IV (greed for premium leads to early assignment risk), and refusing to roll up when the stock rallies hard (locking in capped gains while the stock keeps running). The disciplined covered-call writer treats it as a pure income overlay on a long-term position, not a market-timing tool.
Frequently Asked Questions
Can I sell covered calls in a retirement account?
Yes — covered calls require Level 2 approval and are allowed in IRAs at most brokers.
What if my shares get called away at a price below where I'd want to sell?
Roll the call up and out for a credit before assignment. If you can't roll for a credit, accept the assignment — chasing losing rolls indefinitely usually costs more than just letting the shares go.
