Covered Call Basics: Selling Calls on Stocks You Own

A covered call is the second half of the wheel strategy and one of the most widely used options strategies in the world. You own 100 shares of a stock, you sell a call option against those shares, and you collect premium. If the stock stays below your strike, you keep the premium and your shares. If it rises above, your shares get called away at the strike and you pocket both the premium and any capital gain up to the strike.

Covered calls are approved in IRAs and retirement accounts at most brokers because the risk is fully defined: you already own the shares, so there is no naked exposure. This makes them accessible to almost every investor.

The Mechanics Step by Step

1. You own 100 shares of stock XYZ at a cost basis of $50 per share.
2. You sell 1 XYZ call at the $55 strike, 30 DTE, for $1.20 premium. You immediately receive $120 in your account.
3. If XYZ stays below $55 at expiration: The call expires worthless. You keep the $120 and your 100 shares. You can sell another call.
4. If XYZ rises above $55 at expiration: Your shares are sold (called away) at $55. You keep the $120 premium plus the $500 capital gain ($55 - $50 x 100). Total profit: $620.

The only scenario where a covered call "hurts" is if the stock rockets far above your strike. If XYZ goes to $65, you still exit at $55 and miss out on $10 of upside. This is the tradeoff: you cap your upside in exchange for guaranteed income.

Choosing Your Strike Price

Strike selection depends on your primary goal: income or capital appreciation.

Income-Focused (ATM or Slightly OTM)

If you are running the wheel and want maximum premium, sell calls at-the-money or slightly out-of-the-money (0.30-0.40 delta). These pay the most premium but have the highest probability of being called away. For wheel traders, this is often fine: you collect fat premium, and if shares are called away, you restart the cycle by selling puts.

Growth-Focused (Further OTM)

If you want to keep your shares and earn a little extra income, sell calls further out-of-the-money (0.15-0.20 delta). These pay less premium but have a lower probability of assignment. This approach is better for long-term holdings you do not want to sell.

The Cost Basis Rule

In the context of the wheel, I follow a simple rule: never sell a call below your cost basis unless you are intentionally exiting at a loss. If you were assigned at $48 after selling a put, sell calls at $48 or higher. This ensures that if your shares are called away, you break even or profit on the stock itself, plus you keep all the premium from both the put and call legs.

Choosing Your Expiration

The same theta decay principles from cash-secured puts apply here. I favor 21-35 DTE for covered calls. Shorter expirations (7-14 DTE) can work for weeklies strategies, but the premium per day of capital commitment tends to be worse after transaction costs.

One exception: if a stock has risen sharply and you want to lock in gains, selling a near-term ITM call gives you a high probability of being called away at your target price with a small time premium bonus.

A Real Trade Walkthrough

You were assigned 100 shares of PLTR at $22.50 after a put was exercised. PLTR is now trading at $21.80. Here is how to set up the covered call:

• Strike: $23.00 (above your $22.50 cost basis). Delta is about 0.35.
• Expiration: 28 DTE.
• Premium: $0.72 ($72 per contract).
• Yield: $72 / $2,180 = 3.3% in 28 days, or 43.0% annualized.
• If called at $23: You profit $50 on the stock ($23.00 - $22.50 x 100) plus $72 in premium = $122 total. Plus whatever premium you collected on the original put.

Managing Covered Calls

Taking Profits Early

Just like with puts, I close covered calls at 50% of max profit. If I sold a call for $0.72, I buy it back when it drops to $0.36 or below. This frees up the position to sell another call at a potentially higher strike if the stock has moved, or at the same strike for another round of premium.

When the Stock Drops Significantly

If the stock drops well below your strike, your call will lose most of its value quickly. You can close it for a small debit and sell a new call at a lower strike to collect more premium. Be careful not to sell below your cost basis unless you have decided to exit the position.

In a sharp downturn, the covered call provides limited downside protection (only the premium received). If the stock drops 15%, your $0.72 call premium is a small consolation. This is why stock selection matters: you need to be comfortable holding through drawdowns.

Rolling Up and Out

If the stock rises toward your strike and you want to keep your shares, you can roll: buy back the current call and sell a new one at a higher strike with a later expiration. This should be done for a net credit when possible. Use the roll calculator to evaluate whether a roll makes economic sense before executing.

Covered Calls in the Wheel Cycle

In the wheel strategy, covered calls are not a standalone trade. They are phase two of a cycle. You sell puts until assigned, then sell calls until shares are called away. Each leg collects premium, reducing your cost basis and building income.

The beauty of this cycle is that every outcome leads to the next profitable action. Put expires worthless? Sell another put. Assigned on the put? Sell covered calls. Shares called away? Start selling puts again. Premium flows in at every step.

Tax Considerations

Covered call premium is taxed as short-term capital gains, regardless of how long you have held the shares. Additionally, if you sell an ITM covered call, it can disqualify your shares from long-term capital gains treatment. This matters if you hold shares for appreciation and sell calls as a side income. For wheel traders cycling in and out of positions frequently, everything is typically short-term anyway. Consult a tax professional for your specific situation.
