Selling covered calls is a neutral to bullish trading strategy that can help you make money if the stock price doesn't move.
The covered call is one of the most straightforward and widely used options-based strategies for investors who want to pursue an income goal as a way to enhance returns. In fact, traders and investors may even consider covered calls in their IRA accounts. It’s a pretty basic and straightforward strategy, but there are some things you need to know.
First, let’s nail down a definition. A covered call is a neutral to bullish strategy where you sell one out-of-the-money (OTM) or at-the-money (ATM) call options contract for every 100 shares of stock you own, collect the premium, and then wait to see if the call is exercised or expires. Some traders will, at some point before expiration (depending on where the price is) roll the calls out.
To create a covered call, you short an OTM call against stock you own. If it expires OTM, you keep the stock and maybe sell another call in a further-out expiration. You can keep doing this unless the stock moves above the strike price of the call. When that happens, you can either let the in-the-money (ITM) call be assigned and deliver the long shares, or buy the short call back before expiration, take a loss on that call, and keep the stock.
Traditionally, the covered call strategy has been used to pursue two goals:
Generate income. We’ll look at a simple covered call example. Say you own 100 shares of XYZ Corp., which is trading around $32. There are several strike prices for each expiration month (see figure 1). For now, let’s look at the calls that are OTM, that is, the strike prices are higher than the current price of the underlying stock. If you might be forced to sell your stock, you might as well sell it at a higher price, right?
Some traders take the OTM approach in hopes of the lowest odds of seeing the stock called away. Others get calls that’re close to the stock price, or ATM, to try get the most cash for the calls.

As long as the stock price remains below the strike price through expiration, the option will likely expire worthless. Options are subject to “time decay,” meaning they will decrease in value in the days and weeks to come (all other factors being equal). As the option seller, this is working in your favor.
You might consider selling a 37-strike call (one option contract typically specifies 100 shares of the underlying stock). You run the “risk” of having to sell your stock for $5 more than the current price, so you should be comfortable with that prospect before entering the trade. But you’ll immediately collect $1.85 per share ($185), minus transaction costs. That’s in addition to whatever the stock may return during this time frame. If the call expires OTM, you can roll the call out to a further expiration.
Keep in mind that the price for which you can sell an OTM call is not necessarily the same from one expiration to the next, mainly because of changes in implied volatility (vol). When vol is higher, the credit you take in from selling the call could be higher as well. But when vol is lower, the credit for the call could be lower, as is the potential income from that covered call.

Offsetting a portion of a stock price’s drop. A covered call can compensate to a small degree if the stock price drops, the short call expires OTM, and the short call’s profit offsets the long stock’s loss. But if the stock drops more than the call price—often only a fraction of the stock price—the covered call strategy can begin to lose money. In fact, the covered call’s maximum possible loss is the price at which you buy the stock, minus the credit(s) from short calls plus transaction costs. The bottom line? If the stock price tanks, the short call offers minimal protection.
Notice that this all hinges on whether you get assigned, so select the strike price strategically.
If a stock’s been beaten down and you think a rally is in order, you might decide to forgo the covered call. Even though you may be able to buy back the short call to close it before expiration (or possibly make an adjustment), if you think the stock’s ready for a big move to the upside, it might be better to wait. Conversely, if the underlying had a big run and you think it’s out of steam, then you might more aggressively pursue a covered call.
Once you’re ready to pull the trigger, what strike should you choose? There’s no right answer to this, but here are some ideas to consider:
You might be giving up the potential for hitting a home run if XYZ rockets above the strike price, so covered calls may not be appropriate if you think your stock is going to shoot the moon. But in markets that’re moving more incrementally, this strategy could be beneficial. Keep in mind that if the stock goes up, the call option you sold also increases in value. Because you’re short the call, that position is now going against you, but that’s part of the risk you run with an options-based income strategy.
What happens when you hold a covered call until expiration? First, if the stock price goes up, the stock will most likely be called away perhaps netting you an overall profit if the strike price is higher than where you bought the stock. Second, if the stock price moves up near the strike price at expiration you would get to keep the stock and have the gain from keeping the full premium of the now-worthless option.
A covered call has some limits for equity investors and traders because the profits from the stock are capped at the strike price of the option. The real downside here is chance of losing a stock you wanted to keep. Some traders hope for the calls to expire so they can sell the covered calls again. Others are concerned that if they sell calls and the stock runs up dramatically, they could miss the up move.
Covered calls, like all trades, are a study in risk versus return. With the tools available at your fingertips, you could consider covered call strategies to potentially generate income.

A covered call strategy can limit the upside potential of the underlying stock position, as the stock would likely be called away in the event of substantial stock price increase. Additionally, any downside protection provided to the related stock position is limited to the premium received. (Short options can be assigned at any time up to expiration regardless of the in-the-money amount.)
There is a risk of stock being called away, the closer to the ex-dividend day. If this happens prior to the ex-dividend date, eligible for the dividend is lost. Income generated is at risk should the position moves against the investor, if the investor later buys the call back at a higher price. The investor can also lose the stock position if assigned.
The maximum risk of a covered call position is the cost of the stock, less the premium received for the call, plus all transaction costs.
Rolling strategies can entail substantial transaction costs, including multiple commissions, which may impact any potential return. You are responsible for all orders entered in your self-directed account.
