Frequently Asked Questions
What is a covered call option strategy?
A covered call involves owning 100 shares of stock and selling a call option against those shares to generate instant income (premium), providing a downside buffer while capping upside profit.
How does a covered call provide downside protection?
The cash premium received from selling the call option reduces your cost basis in the underlying stock, lowering your break-even point by the exact premium amount.
What happens if the stock price rises above the call strike price?
Your shares will be called away at the strike price. You keep 100% of the option premium plus any capital appreciation up to the strike price, but forgo gains above the strike.
How do you annualize covered call option yields?
To annualize option yield: (Premium / Stock Price) × (365 / Days to Expiration) × 100.
Can covered call options be sold on dividend-paying stocks?
Yes! Combining dividend yields with option premium yields generates powerful double-digit income streams for long-term buy-and-hold investors.
What is the primary risk of selling covered calls?
The primary risks are capped upside gains during sharp stock rallies and downside loss exposure if the underlying stock drops significantly below your break-even price.
