The Short Answer: It Depends on What You're Optimizing For

Covered calls tend to produce higher income and lower volatility than a straight buy-and-hold position, but they cap your upside during strong bull runs. Buy and hold wins on total return in roaring markets; covered calls win on risk-adjusted income in flat or mildly rising ones. Neither strategy is universally better — the right choice depends on your time horizon, tax situation, and how much you need the stock to run.

This article walks through the mechanics, a side-by-side numerical example, the real risks of each approach, and the tax rules that change the math for US and Canadian investors.

How Each Strategy Actually Works

Buy and hold is exactly what it sounds like. You buy shares and sit on them, collecting dividends if any, and letting price appreciation compound over years or decades. The CBOE's long-run data on the S&P 500 shows this approach has delivered roughly 10% annualized total return before inflation over multi-decade periods. Your only job is to not sell during downturns.

A covered call adds one layer: you sell a call option against shares you already own. The buyer pays you a premium upfront. In exchange, you agree to sell your shares at the strike price if the stock closes above that level on expiration day. If the stock stays below the strike, the option expires worthless, you keep the premium, and you still own the shares. You can then sell another call and repeat the cycle. The Options Industry Council (OIC) describes this as one of the most conservative option strategies available to retail investors because you are never naked — you already own the underlying stock.

Side-by-Side Numerical Example Using AAPL

Let's use Apple (AAPL) at a round price of $190 per share. You own 100 shares, so your position is worth $19,000.

**Scenario: AAPL rises 15% over the next 12 months to $218.50.**

Buy and hold result: Your 100 shares are now worth $21,850. Gain = $2,850, or 15.0% on your $19,000 cost basis. Simple.

Covered call result: At the start of the year you sell a 12-month $200 strike call for $6.50 per share ($650 total premium). Three things can happen:

1. AAPL closes above $200 at expiration. You get called away at $200. You collect $20,000 from the sale plus the $650 premium you already pocketed. Total proceeds = $20,650. Gain = $1,650, or 8.7%. You missed $1,200 of upside because the stock blew past your strike.

2. AAPL closes right at $200. Same outcome as above — called away, 8.7% gain.

3. AAPL stays flat or drops to, say, $185. The call expires worthless. You keep the $650 premium. Your shares are worth $18,500. Net position = $19,150. You are down $500 on the stock but up $650 on premium, for a net gain of $150 (0.8%). Buy and hold would show a loss of $500 (-2.6%).

The pattern is clear: covered calls outperform in flat or slightly down markets. Buy and hold outperforms when the stock makes a big move upward. Over a decade of strong equity bull markets — like 2013 to 2021 — buy and hold on a name like AAPL crushed a capped covered-call strategy in raw total return. But the covered-call seller slept better during choppy years.

What the Long-Run Research and Index Data Show

The CBOE publishes the BXM Index, which tracks a systematic covered-call strategy on the S&P 500 — specifically selling at-the-money monthly calls on SPY. Since its inception data going back to 1986, the BXM has delivered slightly lower total return than the S&P 500 in strong bull markets but with meaningfully lower standard deviation (roughly 30% less volatility by CBOE's own figures).

What does that mean practically? If you owned SPY at $450 and sold monthly at-the-money calls consistently, you would have collected steady premium income — often 1% to 2% per month in high-volatility environments — but you would have capped your participation in every big up month. During the 2022 bear market, the BXM held up noticeably better than the raw index because premium income cushioned the drawdown.

The takeaway from CBOE's data: covered calls are a volatility-reduction tool that trades some upside for income. They are not a return-enhancement tool in trending bull markets.

The Real Risks — Not Buried, Not Sugarcoated

Both strategies carry risk. Here is an honest accounting of each.

**Buy and hold risks:** You absorb the full downside of the stock. A 40% drawdown on AAPL means a 40% loss on your position with no income to offset it. Behavioral risk is real — FINRA has documented that retail investors frequently sell at market bottoms, turning paper losses into permanent ones. You also have zero income from the position beyond dividends.

**Covered call risks:**

Capped upside is the most obvious. If NVDA jumps 60% in a year — as it did in 2023 — and you sold calls at a 10% out-of-the-money strike, you captured only a fraction of that move. You still made money, but far less than a buy-and-hold investor.

Assignment risk is real but manageable. If your shares get called away, you lose the position. If you wanted to keep owning that stock long-term, you now have to repurchase at a higher price, which can trigger a taxable event and a higher cost basis.

Rolling complexity: Many traders try to avoid assignment by rolling the call forward — buying back the expiring call and selling a new one further out. This adds transaction costs and requires active monitoring. It is not a set-and-forget strategy.

Early assignment on American-style options is possible, though uncommon outside of dividend dates. The OIC notes that early assignment risk rises when a call is deep in the money and the stock is about to pay a dividend.

Downside protection is limited. The premium you collect softens losses but does not eliminate them. On a $190 AAPL position, a $6.50 premium only protects you down to $183.50. A serious market selloff still hurts.

Tax Rules That Change the Math for US and Canadian Investors

Tax treatment is where covered calls get complicated, and it is one of the most overlooked factors in strategy comparisons.

**US investors (IRS rules):** Under IRS rules, selling a covered call can affect the holding period of your underlying shares. If you sell an in-the-money call, the IRS may suspend the holding period clock on your shares for the duration of the option. This matters because long-term capital gains rates (0%, 15%, or 20% depending on income) only apply to shares held more than 12 months. Selling aggressive covered calls on shares you have held for 11 months could reset your clock and push you into short-term rates. Premium income from covered calls is generally taxed as short-term capital gain in the year received. Consult a tax professional and review IRS Publication 550 for the qualified covered call rules.

**Canadian investors (CRA rules):** The Canada Revenue Agency treats option premiums received from covered calls as either income or capital gains depending on the frequency of trading and intent. Active traders may have all premium income taxed as business income at full marginal rates. Investors who sell calls occasionally on long-held positions are more likely to have premiums treated as capital gains, where only 50% of the gain is included in income (the inclusion rate in effect for most retail investors — note the CRA has proposed changes, so verify current rules). The CRA's Interpretation Bulletin IT-479R covers transactions in securities and is the primary reference for this treatment.

Bottom line: before running a covered-call program on a large stock position, model the after-tax returns, not just the gross premium income.

Which Strategy Fits Which Investor?

Use this as a rough decision framework.

Covered calls make more sense if: you own shares that have already appreciated significantly and you want income without selling; you expect the market to trade sideways or drift slightly higher; you are in or near retirement and prioritize cash flow over maximum growth; or you hold the stock in a tax-advantaged account (IRA in the US, TFSA or RRSP in Canada) where the tax complications are reduced or eliminated.

Buy and hold makes more sense if: you have a 10-plus year horizon and high conviction in the stock's long-term growth; you own a high-growth name like NVDA or a small-cap where big upside moves are the whole thesis; you do not want to monitor positions monthly; or the tax consequences of assignment would be costly given your current holding period.

Many experienced covered-call traders do both: they hold a core buy-and-hold portfolio for long-term compounding and run covered calls on a separate sleeve of shares where they are comfortable being called away. This hybrid approach lets you collect income without betting the entire portfolio on a capped strategy.

Does selling covered calls hurt long-term returns?

In strong bull markets, yes — covered calls cap your upside, so you will underperform a straight buy-and-hold position when stocks make large moves higher. Over full market cycles that include flat and down periods, the premium income can offset some of that gap. CBOE's BXM Index data shows the covered-call strategy on the S&P 500 has historically delivered slightly lower total return with meaningfully lower volatility than the index itself.

What happens to my shares when a covered call gets assigned?

When your call is assigned, your broker sells your 100 shares at the strike price to the option buyer. You keep the premium you collected when you sold the call, plus the proceeds from the stock sale at the strike. If you want to stay invested in that stock, you would need to repurchase shares at the current market price, which may be higher than your strike.

Can I sell covered calls in my IRA or TFSA?

Yes. The IRS permits covered calls in IRAs, and most major US brokers allow them in retirement accounts at the appropriate options approval level. In Canada, the CRA allows options trading inside a TFSA or RRSP, though the CRA has warned that frequent active trading in a TFSA can be classified as business income and lose its tax-sheltered status. Confirm your broker's specific rules before trading.

How much income can I realistically expect from covered calls?

Premium income varies with implied volatility, strike distance, and time to expiration. On a liquid large-cap like AAPL or MSFT in a normal volatility environment, selling a 30-day call roughly 5% out of the money might generate 0.5% to 1.5% of the stock's value per month. In high-volatility periods that range can expand significantly, but higher premium also signals higher expected risk in the underlying stock.

Does selling a covered call affect my stock's holding period for tax purposes?

It can. Under IRS rules, selling a deep in-the-money covered call that does not qualify as a 'qualified covered call' may suspend the holding period on your shares, potentially converting a long-term gain into a short-term gain if the shares are later sold or called away. IRS Publication 550 covers the qualified covered call rules in detail, and a tax advisor can help you structure strikes to avoid this issue.

Is a covered call strategy better than just holding SPY?

Not necessarily better — different. The CBOE BXM Index, which mimics a systematic covered-call overlay on the S&P 500, has historically lagged SPY's total return in strong bull markets but experienced smaller drawdowns in bear markets. If you value income and lower volatility over maximum growth, the covered-call approach has merit. If you are a long-term accumulator with decades ahead, plain SPY buy-and-hold has historically been hard to beat on a total-return basis.
