Covered Call

What Is a Covered Call?

A covered call sells one call option against 100 shares you own. The “covered” designation means the short call is backed by actual shares — if assigned, you deliver the shares without buying them at market price. This distinguishes it from a “naked” call where the seller has no underlying position.

You sell a call with a strike above the current price, collect premium immediately, and take the obligation to sell shares at the strike if the stock closes above it at expiration. If the stock stays below the strike, the call expires worthless and you keep the premium. If the stock exceeds the strike, you sell shares at the strike and keep the premium.

Breakeven is your original stock cost minus the premium collected. Buy stock at $50, collect $2.00 premium, and your effective cost basis is $48. Maximum profit is capped at the strike price plus premium collected.

Why It Matters for Options Traders

Covered calls are the entry point for most investors into options selling. They’re approved for the most conservative options trading levels at brokerages because the position is fully collateralized by the shares. The strategy transforms a static stock holding into an income-generating position through systematic premium collection.

The tradeoff is capped upside. By selling the call, you forfeit any gains above the strike price. If you own a stock at $50, sell the $55 call, collect $1.50, and the stock rips to $70, you sell at $55 for $6.50 profit ($5 price gain + $1.50 premium) — missing the full $20 gain. For this reason, covered calls are most effective in sideways to modestly bullish markets where you don’t expect large upside moves.

Strike and expiration selection drive covered call outcomes. Selling a call closer to the money (30 delta range) generates more premium but limits upside more aggressively. Selling further OTM (15-20 delta) collects less premium but allows more room for the stock to run. Most systematic covered call strategies target 30-45 DTE expirations, collecting theta decay during the period of fastest time decay, and often close the short call at 50% of premium collected rather than holding through expiration.

Key Characteristics

• Requires stock ownership: Must own 100 shares per contract sold — the position is collateralized by the underlying
• Premium income: Immediate cash collected offsets cost basis and provides a downside buffer
• Capped upside: Gains above the strike price are surrendered; maximum profit is strike + premium collected - cost basis
• Assignment risk: If the stock closes above the strike at expiration, shares are called away at the strike price
• Partial downside protection: Premium collected reduces breakeven but does not fully protect against large stock declines
• Systematic income: Many investors sell covered calls monthly or on a rolling basis as a yield-enhancement strategy
