A covered call is an options income strategy where you sell call options contracts against shares you already own. When you sell a call option, you're giving the buyer the right to purchase your stock at a predetermined price (the strike price) by a specific date. In return, you collect the option premium—immediate income paid upfront. This strategy is called "covered" because you own the underlying shares, reducing your risk compared to naked call selling.
How It Works
Here's the mechanics: You own 100 shares of a company trading at $50. You sell one call option contract (representing 100 shares) with a $55 strike price expiring in 30 days, collecting a $2 premium per share ($200 total). You keep this premium regardless of what happens next. If the stock stays below $55, the option expires worthless and you keep both your shares and the premium. If the stock rises above $55, the buyer exercises the option and you must sell your shares at $55—a profit, but you miss further gains.
Why It Matters for Investors
For high-net-worth investors, covered calls serve several purposes. First, they generate consistent income on holdings you're willing to part with. Second, they provide a built-in exit strategy if a stock appreciates as hoped. Third, they reduce cost basis—the premium collected lowers your effective purchase price. However, this strategy caps upside potential and introduces assignment risk if shares get called away at an inopportune time. It works best on stable stocks you're neutral-to-bullish on rather than positions you expect to skyrocket.
Example
Suppose you purchased 500 shares of a dividend-paying tech stock at $40 per share (total investment: $20,000). The stock has appreciated to $48. Rather than hold and hope for further gains, you sell five call contracts with a $50 strike price for the next two months, collecting $1.50 per share ($750 total). If the stock stays under $50, you keep the shares plus $750 in premium income—an effective return of 3.75% in two months. If it rises to $52, your shares get called away at $50, earning you a $10 per share gain plus the premium. You miss the additional $2 per share upside, but you achieved a satisfactory outcome.
Key Takeaways
- Covered calls generate immediate income through option premium collection while maintaining stock ownership until exercise
- Upside is capped at the strike price; you sacrifice unlimited gains for defined income
- Best used on positions you're willing to sell or stocks you expect to trade sideways
- Reduces portfolio volatility and effective cost basis, making it popular for income-focused investors
- Works effectively when combined with dividend investing or tactical allocation strategies
