Definition

A covered call is the simplest and most conservative options strategy. The investor owns 100 shares of a stock and simultaneously sells one call option contract against those shares at a strike price above the current market price. The call is “covered” because the obligation to deliver shares (if the buyer exercises) is already backed by the shares sitting in the account — no additional capital is at risk beyond what was already invested in the stock.

In exchange for accepting an upper limit on potential profits, the seller collects a premium upfront. That premium is theirs to keep regardless of how the trade resolves. The trade-off is one-dimensional: give up upside above the strike in return for guaranteed income today.

Because it carries no incremental risk versus owning the stock outright, the covered call is approved at the lowest brokerage permission tier (Level 1) and is the only options strategy commonly allowed in retirement accounts (IRAs). It is the entry point through which most investors first encounter options.

Why it matters

Key takeaways

• 'Covered' means you own the underlying 100 shares per contract sold. A naked call has unlimited risk; a covered call has the same risk profile as owning the stock minus the upside above the strike.
• Two outcomes at expiration: stock stays below strike → keep premium and stock; stock closes above strike → shares are called away at strike, but you keep both the premium and the gain up to the strike.
• Covered calls reduce the cost basis of a long stock position by the premium collected — a 1–2% monthly yield compounds meaningfully over a year.
• Best for flat or slowly rising stocks. A roaring bull market in your name means the strategy underperforms — you sold the upside.
• Strike selection trades off premium vs. assignment risk. ATM strikes pay the most premium; OTM strikes are less likely to be assigned but pay less.
• Repeatable monthly. Many investors run covered calls as a perpetual yield-enhancement overlay on long-term holdings.

Read it as: Either outcome is profitable for the covered call writer. The “worst case” relative to expectations is that the stock rips through the strike and the shares are called away — meaning the trade still made money but missed additional upside. The only real loss scenario is a large decline in the stock itself, which would also affect a plain stockholder.

When the strategy fits

Covered calls shine on quality stocks you would happily hold long-term anyway. Selling calls on a position you secretly want to dump is a setup for regret — if it rallies, you lose the upside; if it falls, the premium is small consolation.
