Biggest Covered Call Mistakes Beginners Make (And How to Avoid Them)

The Short Answer: What Trips Up Most New Covered-Call Sellers

Most beginners who sell covered calls lose money not because the strategy is flawed, but because they make the same handful of avoidable errors: chasing high premiums on volatile stocks, picking strike prices that are too close to the current price, and ignoring the tax consequences of assignment. If you can sidestep those three traps, you are already ahead of the majority of first-year covered-call traders.

Mistake 1: Chasing Premium Without Checking Implied Volatility

A fat premium looks great on paper. But a fat premium almost always means the market is pricing in a big move in the underlying stock. That is implied volatility (IV) doing its job.

Here is a concrete example. Suppose NVDA is trading at $875 and you see a 30-day call option at the $900 strike paying $28 in premium. That sounds like easy income. But if NVDA's IV rank is 80 — meaning volatility is near its highest level in a year — the market is telling you a large price swing is likely. If NVDA drops to $780 in the next two weeks, your $28 in collected premium barely dents a $95 unrealized loss on your shares.

The fix: check IV rank or IV percentile before selling. The CBOE publishes volatility data and educational material on how implied volatility affects option pricing. A general rule of thumb used by experienced traders is to sell calls when IV rank is above 30, but to size your position conservatively when IV rank is above 60, because the same conditions that inflate your premium can also produce violent moves against your stock position.

Mistake 2: Selling the Call Too Close to the Current Stock Price

New traders often sell at-the-money (ATM) calls because the premium is highest there. The problem is that ATM calls have a delta near 0.50, which means there is roughly a 50% chance the stock closes above your strike at expiration and gets called away.

Let's use AAPL as an example. Say AAPL is at $192 and you sell the $193 call expiring in 21 days for $3.10 per share ($310 per contract). If AAPL runs to $201 by expiration, your shares get called away at $193. You collected $3.10, but you missed $8 of upside. Worse, if you want to buy AAPL back to keep running the strategy, you now pay $201 for shares you just sold at $193.

The fix: most income-focused covered-call traders target strikes with a delta between 0.20 and 0.35 — roughly 20 to 35 points out of the money on a percentage basis. On that same AAPL trade, a $200 strike might pay $1.40 instead of $3.10, but it gives the stock much more room to move before you lose your shares. The Options Industry Council (OIC) offers free courses explaining how delta relates to the probability of an option expiring in the money — worth reviewing before you pick your first strike.

Mistake 3: Ignoring Assignment Risk Around Earnings and Dividends

Two calendar events can trigger early assignment on your short call: earnings announcements and ex-dividend dates.

On the dividend side, if you sell a call on a stock that pays a dividend and the call is deep in the money, the call buyer may exercise early the day before the ex-dividend date to capture that dividend. Suddenly your shares are gone before you planned. FINRA and the OIC both note that American-style equity options — which is what most retail traders use on US stocks — can be exercised at any time before expiration, not just at expiration.

On the earnings side, IV typically spikes before a report and collapses after — a phenomenon called IV crush. If you sell a call the week before earnings hoping to collect elevated premium, you are also accepting the risk that a blowout earnings report sends the stock 15% higher and your shares get called away at your strike, far below the new market price.

The fix: check the earnings calendar and ex-dividend date before selling any call. Many traders simply avoid selling calls in the two weeks before an earnings report on stocks they are not willing to sell.

Mistake 4: Forgetting About Taxes — Including the Wash-Sale Trap

Covered calls create taxable events that many beginners do not anticipate. In the United States, the IRS treats premiums you collect as short-term capital gains in the year the option expires, is closed, or results in assignment. If your shares get called away, the premium you collected is added to your sale proceeds, which affects your cost-basis calculation.

There is also a lesser-known trap: the wash-sale rule. According to IRS Publication 550, selling a covered call that is deep in the money can suspend the holding period on your underlying shares. If you have held MSFT for 11 months and you sell a deep in-the-money call, the IRS may reset your holding period clock, potentially turning a long-term capital gain into a short-term one if the shares are called away.

For Canadian investors, the Canada Revenue Agency (CRA) has its own rules. Premiums received from writing covered calls are generally treated as capital gains, but if the CRA determines you are trading frequently enough to be considered a business, those gains can be reclassified as ordinary income — a meaningful difference at tax time.

The fix: keep a trade log, track your cost basis carefully, and consult a tax professional who understands options before year-end. Do not rely on your broker's 1099 alone to catch every nuance.

Mistake 5: Not Having a Plan for When the Trade Goes Wrong

A covered call limits your upside but does not protect your downside. If the stock falls hard, you still own all of that loss minus the small premium you collected. Beginners often freeze when a stock drops 20% because they do not know whether to buy back the call, hold, or sell the stock.

Consider a real scenario: you own 100 shares of SPY at $520 and sell the $530 call for $4.50. SPY then drops to $490. Your call is now nearly worthless — you could buy it back for $0.15 — but your stock position is down $30 per share. The $4.50 premium you collected covers less than 15% of that loss.

The fix: before you sell any covered call, write down three things — the price at which you will buy back the call early to cut losses, the price at which you will accept assignment without regret, and the maximum loss you are willing to absorb on the stock itself. Experienced traders often set a rule like: if the short call drops to 10% of the original premium received, buy it back and reassess. This keeps you from holding a losing position out of inertia.

Mistake 6: Selling Calls on Stocks You Cannot Afford to Lose

This is the most emotionally costly mistake on the list. Covered calls work best when you are genuinely neutral-to-slightly-bullish on a stock and would be comfortable selling it at the strike price. If you are selling calls on a concentrated position that represents 40% of your net worth, assignment is not just a financial event — it is a life-disrupting one.

The SEC has published investor education materials reminding retail investors that options strategies, including covered calls, carry real risk of loss and are not suitable for every investor or every position size.

The fix: only sell covered calls on positions you would be willing to sell at the strike price on any given day. If you would be devastated to lose those shares — because of sentimental value, a large embedded gain you are not ready to realize, or because the position is too large — do not sell the call. Income is not worth the stress of an unwanted assignment.

What is the most common covered call mistake beginners make?

The single most common mistake is chasing the highest available premium without understanding why that premium is so large. High premiums almost always reflect high implied volatility, which means the market expects a big price move — and that move can easily wipe out the income you collected. Always check IV rank before selling a call.

Can I lose money selling covered calls?

Yes. While the premium you collect reduces your cost basis slightly, you still own the underlying stock and absorb its full downside. If a stock you own drops 30%, the $200 or $300 in premium you collected does very little to offset that loss. Covered calls limit upside but do not protect the downside.

What happens if my covered call gets assigned early?

Early assignment means the call buyer exercised their right to buy your shares before expiration, and your broker sells your 100 shares at the strike price. This most commonly happens the day before an ex-dividend date on deep in-the-money calls. The OIC and FINRA both note that American-style equity options can be exercised at any time, so always check the dividend calendar before selling.

How do I pick the right strike price for a covered call?

Most income-focused traders target a strike with a delta between 0.20 and 0.35, which gives the stock meaningful room to rise before the shares get called away. A lower delta means less premium but a lower probability of assignment. The right balance depends on how much upside you are willing to give up in exchange for income.

Do covered calls affect my taxes?

Yes, in important ways. In the US, the IRS treats collected premiums as short-term capital gains, and selling a deep in-the-money call can suspend your holding period on the underlying shares under the wash-sale rules outlined in IRS Publication 550. In Canada, the CRA generally treats covered-call premiums as capital gains, but frequent trading can cause them to be reclassified as business income. Consult a tax professional familiar with options.

Should I sell covered calls before an earnings report to get higher premium?

Most experienced traders avoid it. Implied volatility — and therefore premium — spikes before earnings, which makes calls look attractive. But if the stock jumps sharply on a strong report, your shares can be called away far below the new market price, and you miss all of that gain. The risk-reward is usually unfavorable unless you are fully prepared to sell the stock at your strike no matter what.
