Covered Call Explained
- Covered Call Explained
A covered call is a popular options strategy, often recommended for beginner investors seeking to generate income from stocks they already own. This article provides a detailed explanation of covered calls, covering their mechanics, benefits, risks, and practical implementation. We will explore scenarios, break-even points, and important considerations for successfully employing this strategy.
What is a Covered Call?
At its core, a covered call involves *selling* a call option on a stock you *already own*. Let's break that down:
- **Stock Ownership:** You must own 100 shares of the underlying stock for each call option contract you sell. This is the "covered" part – you have the stock to deliver if the option is exercised.
- **Call Option:** A call option gives the buyer the right, but not the obligation, to *buy* 100 shares of the stock from you at a predetermined price (the *strike price*) on or before a specific date (the *expiration date*).
- **Selling the Option:** When you sell a call option, you receive a premium from the buyer. This premium is your immediate profit.
- **Obligation to Sell:** If the stock price rises *above* the strike price at or before expiration, the option buyer will likely exercise their right to buy the stock from you at the strike price. You are then obligated to sell your shares at that price.
Essentially, you're betting that the stock price will either stay flat or increase only modestly. You are willing to cap your potential gains in exchange for the premium income.
Key Terminology
Understanding these terms is crucial:
- **Underlying Asset:** The stock upon which the option is based (e.g., Apple, Tesla, Microsoft).
- **Strike Price:** The price at which the option buyer can buy the stock if they exercise the option.
- **Expiration Date:** The date on which the option contract expires. After this date, the option is worthless.
- **Premium:** The price the option buyer pays to the option seller (you) for the right to buy the stock. This is your profit if the option expires worthless.
- **In-the-Money (ITM):** A call option is ITM when the stock price is *above* the strike price. Exercising the option would result in a profit for the buyer.
- **At-the-Money (ATM):** A call option is ATM when the stock price is equal to the strike price.
- **Out-of-the-Money (OTM):** A call option is OTM when the stock price is *below* the strike price. Exercising the option would result in a loss for the buyer.
- **Option Chain:** A list of available call and put options for a specific underlying asset, showing strike prices, expiration dates, and premiums. You can find these on your broker's platform.
- **Volatility:** A measure of how much the price of a stock is expected to fluctuate. Higher volatility generally leads to higher option premiums. See Volatility Skew for more details.
- **Time Decay (Theta):** The rate at which an option loses value as it approaches its expiration date. This works in your favor as a covered call seller. See Theta Decay for an in-depth explanation.
How Does a Covered Call Work? A Practical Example
Let's say you own 100 shares of XYZ stock, currently trading at $50 per share. You believe the stock will trade sideways or increase slightly in the near term.
1. **You Sell a Call Option:** You sell one call option contract with a strike price of $55, expiring in one month. You receive a premium of $1 per share, or $100 for the contract (since one contract controls 100 shares). 2. **Scenario 1: Stock Price Remains Below $55:** If XYZ stock stays below $55 at expiration, the option expires worthless. You keep the $100 premium, and you still own your 100 shares of XYZ stock. This is the ideal outcome. Your total profit is $100. 3. **Scenario 2: Stock Price Rises to $58:** If XYZ stock rises to $58 at expiration, the option buyer will exercise their option. You are obligated to sell your 100 shares at $55 per share, even though they are worth $58 in the market.
* You receive $5500 from the sale of your shares (100 shares x $55). * You already received a $100 premium. * Your total profit is $600 ($5500 + $100 - $5000 original cost of shares). * You've capped your potential profit. You missed out on the extra $3 per share ($58 - $55).
4. **Scenario 3: Stock Price Falls to $45:** If XYZ stock falls to $45 at expiration, the option expires worthless. You keep the $100 premium, but you have an unrealized loss of $500 on your stock investment (100 shares x $5 loss). The premium partially offsets your loss, resulting in a net loss of $400.
Benefits of a Covered Call
- **Income Generation:** The primary benefit. The premium received provides immediate income on stocks you already own.
- **Partial Downside Protection:** The premium received can offset some of the losses if the stock price declines. However, it's important to remember this protection is limited.
- **Simple Strategy:** Relatively easy to understand and implement, making it suitable for beginners. However, always understand the risks. Compare with Protective Put.
- **Reduced Cost Basis:** The premium received effectively lowers your cost basis in the stock.
Risks of a Covered Call
- **Capped Upside Potential:** You limit your potential profit if the stock price rises significantly above the strike price. You are forced to sell your shares at the strike price, missing out on further gains.
- **Downside Risk Remains:** You still face the risk of losing money if the stock price falls significantly. The premium provides only limited protection.
- **Opportunity Cost:** If the stock price rises sharply, you may regret selling the call option and missing out on larger profits.
- **Early Assignment:** Although rare, the option buyer can exercise the option *before* the expiration date, especially if a dividend is paid. This can disrupt your strategy. See American vs. European Options.
- **Tax Implications:** Option trading has specific tax rules. Consult a tax professional.
Choosing the Right Strike Price and Expiration Date
Selecting the appropriate strike price and expiration date is crucial for a successful covered call strategy.
- **Strike Price:**
* **At-the-Money (ATM):** Offers a moderate premium but limits potential gains significantly. * **Out-of-the-Money (OTM):** Offers a lower premium but allows for more upside potential. This is often preferred by investors who are slightly bullish on the stock. * **In-the-Money (ITM):** Offers a higher premium but severely limits upside potential. Generally not recommended unless you are very bearish on the stock and are primarily seeking income.
- **Expiration Date:**
* **Short-Term (Weeks):** Offers a smaller premium but allows you to frequently rotate the strategy. * **Long-Term (Months):** Offers a larger premium but ties up your shares for a longer period and exposes you to more risk.
Generally, a slightly OTM strike price with a 30-60 day expiration is a good starting point for beginners.
Advanced Considerations
- **Rolling the Option:** If the stock price approaches the strike price, you can "roll" the option by buying back the existing option and selling a new option with a higher strike price or a later expiration date. This allows you to potentially capture more upside.
- **Diagonal Spreads:** Combining different strike prices and expiration dates to create a more complex strategy.
- **Tax-Loss Harvesting:** Utilizing covered calls in conjunction with tax-loss harvesting to optimize your portfolio's tax efficiency. Capital Gains Tax is an important consideration.
- **Dividend Capture:** Selling covered calls on dividend-paying stocks to generate additional income.
- **Implied Volatility (IV):** Understanding how IV affects option premiums. High IV generally means higher premiums. See Implied Volatility and Options Pricing.
- **Delta:** A measure of how much the option price is expected to change for a $1 change in the stock price. Useful for understanding risk. See Option Greeks.
- **Gamma:** A measure of how much the delta is expected to change for a $1 change in the stock price.
