The covered call is a strategy employed by both new and experienced traders. Because it is a limited risk strategy, it is often used in lieu of writing calls “naked” and, therefore, brokerage firms do not place as many restrictions on the use of this strategy. You will need to be approved for options by your broker before using this strategy, and you will likely need to be specifically approved for covered calls.

Read on as we cover this option strategy and show you how to use it to your advantage.

Key Takeaways

  • A covered call involves selling an upside call option representing the exact amount of a pre-existing long position in some asset or stock.
  • The writer of the call earns in the options premium, enhancing returns when the underlying is in a sideways market.
  • A covered call will, however, limit upside potential and does not protect against the portfolio losing value in a down market.

Options Basics

A call option gives the buyer the right, but not the obligation, to buy the underlying instrument (in this case, a stock) at the strike price on or before the expiry date. For example, if you buy July 40 XYZ calls, you have the right, but not the obligation, to purchase XYZ at $40 per share any time between now and the July expiration.

This type of option can be precious in the event of a significant move above $40. Each option contract you buy is for 100 shares. The amount the trader pays for the option is called the premium.

There are two values to the option, the intrinsic and extrinsic value, or time premium. Using our XYZ example, if the stock is trading at $45, our July 40 calls have $5 of intrinsic value. If the calls are trading at $6, that extra dollar is the time premium. If the stock is trading at $38 and our option is trading at $2, the option only has a time premium and is said to be out of the money (OTM).

Option sellers write the option in exchange for receiving the premium from the option buyer. They are expecting the option to expire worthless and, therefore, keep the premium. For some traders, the disadvantage of writing options naked is the unlimited risk. When you are an option buyer, your risk is limited to the premium you paid for the option. But when you are a seller, you assume a significant risk.

Refer back to our XYZ example. The seller of that option has given the buyer the right to buy XYZ at 40. If the stock goes to 50 and the buyer exercises the option, the option seller will be selling XYZ at $40. If the seller does not own the underlying stock, it will have to be bought on the open market for $50 and then sold at $40. Clearly, the more the stock’s price increases, the greater the risk for the seller.

Note

Options sometimes have an unfair reputation as being complex and reserved only for advanced traders, but as you’ll learn in Investopedia Academy’s Options for Beginners course, that isn’t the case. With clear and concise explanations of what options are and how to use them in your favor, you’ll quickly discover how options trading can take you where stocks can’t.

How a Covered Call Can Help

In the covered call strategy, we will assume the role of the option seller. However, we will not assume unlimited risk because we will already own the underlying stock. This gives rise to the term “covered” call because you are covered against unlimited losses in the event that the option goes in the money and is exercised.

The covered call strategy requires two steps. First, you already own the stock. It needn’t be in 100 share blocks, but it will need to be at least 100 shares. You will then sell, or write, one call option for each multiple of 100 shares: 100 shares = 1 call or 200 shares = 2 calls.

When using the covered call strategy, you have slightly different risk considerations than you do if you own the stock outright. You do get to keep the premium you receive when you sell the option, but if the stock goes above the strike price, you have capped the amount you can make. 

When to Use a Covered Call

There are many reasons traders employ covered calls. The most common is to produce income on a stock that is already in your portfolio. You may believe that in the current market environment, the stock’s price is not likely to appreciate, or it might even drop.

Even with knowing this, you may still want to hold onto the stock, possibly as a long-term hold, for dividend or tax reasons. As a result, you may decide to write covered calls against the position.

Alternatively, many traders look for opportunities on options they feel are overvalued and will offer a good return. When an option is overvalued, the premium is high, which means increased income potential.

To enter a covered call position on a stock that you do not own, you should simultaneously buy the stock (or already own it) and sell the call. Remember when doing this that the stock may go down in value. While the option risk is limited by owning the stock, there is still risk in owning the stock directly.

What to Do at Expiration

Eventually, we will reach expiration day. If the option is still out of the money, likely, it will just expire worthless and not be exercised. In this case, you don’t need to do anything. You could then write another option against your stock if you wish. 

If the option is in the money, expect the option to be exercised. Depending on your brokerage firm, everything is usually automatic when the stock is called away. Be aware of what fees will be charged in this situation, as each broker will be different. You will need to be aware of this so that you can plan appropriately when determining whether writing a given covered call will be profitable.

Let’s look at a brief example. Suppose that you buy 100 shares of XYZ at $38 and sell the July 40 calls for $1. In this case, you would bring in $100 in premiums for the option you sold. This would make your cost basis on the stock $37 ($38 paid per share – $1 for the option premium received).

If the July expiration arrives and the stock is trading at or below $40 per share, it is very likely that the option will expire worthless, and you will keep the premium. You can then continue to hold the stock and write another option if you choose.

If, however, the stock is trading at $41, you can expect the stock to be called away. You will be selling it at $40, which is the option’s strike price. But remember, you brought in $1 in premium for the option, so your profit on the trade will be $3 (bought the stock for $38, received $1 for the option, stock called away at $40).

Likewise, if you had bought the stock and not sold the option, your profit in this example would be the same $3 (bought at $38, sold at $41).

If the stock is higher than $41, the trader who held the stock and did not write the 40 call would be gaining more, whereas, for the trader who wrote the 40 covered call, the profits would be capped.

Risks of Covered Call Writing

The risks of covered call writing have already been briefly touched upon. The main risk is missing out on stock appreciation in exchange for the premium. If a stock skyrockets because a call was written, the writer only benefits from the stock appreciation up to the strike price, but no higher. In strong upward moves, it would have been favorable to hold the stock and not write the call. 

While a covered call is often considered a low-risk options strategy, that isn’t necessarily true. While the risk on the option is capped because the writer owns shares, those shares can still drop, causing a significant loss. However, the premium income helps slightly offset that loss. 

This brings up the third potential downfall. Writing the option is one more thing to monitor. It makes a stock trade slightly more complicated and involves more transactions and more commissions. 

Can You Lose Money on a Covered Call?

Yes, you can lose money on a covered call. If the stock price drops below the breakeven point in a covered call, you will lose money.

Is a Covered Call Bullish or Bearish?

A covered call is a neutral to bullish trade. The trader will sell either one out-of-the-money (OTM) or at-the-money (ATM) call option, collecting the premium, and then waiting on whether the call expires or is executed.

Why Are Covered Calls Bad?

Covered calls are not necessarily bad. It is recommended not to write covered calls for stocks with high growth potential. The reason is that the upside gain will be missed because you’ll be required to sell at the strike price.

The Bottom Line

The covered call strategy works best on stocks where you do not expect a lot of upside or downside. Essentially, you want your stock to stay consistent as you collect the premiums and lower your average cost every month. Remember to account for trading costs in your calculations and possible scenarios.

Like any strategy, covered call writing has advantages and disadvantages. If used with the right stock, covered calls can be a great way to reduce your average cost or generate income.
