Covered Calls: Generating Premium on Shares I Own
A covered call involves selling a call option against shares you already own. In exchange for receiving premium, you accept the obligation to sell 100 shares per contract at the strike price if assigned. I use covered calls to generate premium around my long-term stock portfolio. The tradeoff is important: the premium provides income, but the call can limit my upside if the stock rises significantly above the strike price.
The Stock Comes First
I do not buy stocks simply because the options premium is attractive. First, I decide whether I want to own the company. Once I own the shares, I evaluate whether selling a covered call makes sense. My underlying investment thesis remains more important than the premium available in the options chain.
How Covered Calls Work
Let's say you own 100 shares of XYZ stock, currently trading at $50. Let's say you plan to hold it long term, but would sell if it reached $55.
You can sell a $55 strike call option that expires in 30 days. Let's say a buyer pays you $1.00 per share for this option. Because an options contract controls 100 shares, you receive $100 immediately into your account. This is the "premium."
Now, two things can happen at expiration in 30 days:
- Scenario A: The stock stays below $55. The option expires worthless. You keep your 100 shares AND the $100 premium. You can then sell another covered call the next month.
- Scenario B: The stock goes above $55. The option is exercised. You are forced to sell your 100 shares at $55. However, you still keep the $100 premium. Your total profit is the stock appreciation (from $50 to $55 = $500) plus the premium ($100), for a total gain of $600.
Selling on Up Days
I generally prefer selling covered calls on up days. When a stock moves higher, call premiums may become more attractive and I can often select a higher strike while still receiving premium.
This is a preference, not a guarantee that the timing will be optimal. I would rather wait for a setup I like than sell a covered call simply because I have 100 shares available.
Strike Selection and Delta Targets
I generally target approximately 0.10 to 0.20 delta when selling covered calls. My goal is usually to collect premium while reducing the probability that the option finishes in the money.
Lower delta also means accepting less premium. I am intentionally making that tradeoff because I generally prefer keeping my long-term shares. Delta is commonly used as a rough proxy for the probability of expiring ITM, but it is not a guarantee.
Why I Sometimes Accept Low Premium
Because I generally sell lower-delta covered calls, the premium can be relatively small. That is intentional. My primary goal is long-term portfolio growth. I do not want to collect a large premium today only to cap significant upside in a company I believe can appreciate substantially. Sometimes the available premium is not worth the obligation. In that situation, I simply do not sell a covered call.
Covered-Call Premium Is Not Free Money
Covered-call premium is not free money. If the stock rises significantly above my strike, I may give up substantial upside or need to manage the short call. If the stock falls, the premium only offsets a portion of the decline in my shares. The underlying stock remains the primary driver of the combined position’s profit or loss.
Expiration and Macro Event Review
I generally favor shorter expirations, often 7 to 14 DTE. Shorter contracts allow me to reassess the stock and strike more frequently. I may occasionally sell further out depending on the company, available premium, and market conditions.
Before selling a covered call, I review upcoming earnings and major scheduled macroeconomic events, including Federal Reserve meetings, inflation data, and labor reports. I am particularly cautious around events that can create a sharp move in the underlying stock. Higher premium before an event generally reflects higher expected volatility.
When a Covered Call Moves Against Me
If a covered call moves in the money and I want to keep the shares, I may roll the position. I think about three variables: strike, expiration, and premium. My priority is generally moving the strike higher while keeping the new expiration as short as practical. I only roll for a net credit.
Rolling closes the existing contract and opens a new contract. The original call may realize a loss. The new position provides a different strike, additional time, and additional premium.
I rarely close covered calls early simply because they have reached a specific percentage of maximum profit. I generally prefer allowing contracts to expire worthless when the position remains within my risk tolerance. I manage positions when the underlying stock, assignment risk, or my investment thesis gives me a reason to act.
Assignment and Call-Away Risk
If assigned on a covered call, I may be required to sell 100 shares per contract at the strike price. Assignment can occur before expiration, although the risk generally becomes more relevant when the call is in the money and has little remaining extrinsic value. This is why I consider the strike before opening the contract. If I am completely unwilling to sell the shares at that price, I need to reconsider whether the premium is worth accepting the obligation.
When the Stock Falls
A covered call does not protect a stock position from a major decline. The premium received only provides a limited offset.
If a stock falls significantly below my cost basis, selling calls above my cost basis may produce very little premium. Selling a lower strike may increase premium but also creates the risk of having the shares called away below my preferred exit price. In those situations, I may simply hold the stock. I do not force covered-call income from every position every week.
Distinguishing Covered Calls from PMCCs
Most covered calls in this discussion refer to calls backed by shares I own. I may also sell calls against qualifying long-dated call positions as part of a poor man’s covered call strategy. That structure has different risks and is discussed separately in the Poor Man's Covered Call (PMCC) guide.
