Are covered call ETFs worth it? High yields vs. total return explained
By Aparna Gill, CFA, CFP® 31 August 2026 4 min read
Key takeaways
- A covered call ETF is an investment fund that uses a special income-generating strategy to pay a regular—often monthly—cash payout.
- Yield is not the same as your total return. An ETF advertising a 12% monthly payout can still lose you money if the underlying stock prices drop significantly.
- Capped upside. In exchange for getting immediate cash today, you give up the chance to fully profit when the stock market goes on a major run.
Canadian investors are currently flooded with choices designed to boost the income their portfolios generate. "Covered call" ETFs—which are often marketed as “premium income” or “enhanced income” funds—have become incredibly popular. They advertise double-digit monthly payouts, all backed by the familiar, big-name stocks you already know.
However, a high headline yield can be misleading on its own. True long-term wealth creation comes down to total return—which is the combination of the income you receive plus the growth (or loss) of your original investment amount.
Before adding these innovative income tools to your portfolio, it’s important to look under the hood. You need to understand whether trading away tomorrow's growth in exchange for today's cash flow actually helps you reach your long-term financial goals.
How the covered call strategy actually works
To evaluate covered call strategies, we need to look past the marketing and understand the basic mechanics.
At their core, these funds operate just like standard ETFs. They buy a normal basket of stocks to track a well-known market, like the biggest companies in Canada or the US. But then, the portfolio manager adds a twist: they sell, or "write," call options against some of those stock positions.
What is a call option? Think of it as a financial contract. When an ETF sells a call option, it collects an upfront cash payment, known as a premium. In exchange for that cash, the ETF promises the buyer the right to purchase the underlying stock from the fund at a set price (the "strike price") within a certain timeframe.
The upfront cash collected from selling these contracts is what funds the steady, high monthly payouts you receive as an investor. But getting this immediate cash creates a major trade-off.
Capped upside (the trade-off): By taking that upfront cash, the fund manager puts a ceiling on how much the ETF can grow. If the stock market suddenly takes off and prices soar, the fund is legally forced to sell its winning stocks at that lower, pre-agreed strike price. As an investor, you get to keep your monthly income, but you miss out on the big gains from the market rally.
Also, because managing these options contracts requires a lot of active, hands-on work by the fund managers, these ETFs charge noticeably higher fees (MERs) than your standard, passive index funds.
The hidden risk: Return of capital (ROC)
Sometimes, the cash the fund collects from selling options isn't enough to pay that big advertised yield—especially when the stock market is calm. To make up the difference and keep the payouts high, fund managers might use something called return of capital (ROC).
ROC simply means the fund is handing a portion of your original investment dollars back to you. This creates two critical implications to watch out for:
- Your investment shrinks: Getting your own money back feels nice, like receiving a dividend. But it means your core investment is actually getting smaller. With less money left working for you inside the fund, it becomes much harder for your portfolio to recover when the stock market bounces back.
- A deferred tax bill: If you hold this fund outside of a registered account such as an RRSP or TFSA, getting your capital returned isn't taxed right away. It feels tax-free, but it actually lowers the "book value" (adjusted cost base) of your investment. You aren't avoiding tax—you are just delaying it. When you finally sell the ETF years later, you will likely face a much larger capital gains tax bill.
Performance across different markets
To picture how covered call ETFs compare to standard index ETFs, let's look at how both handle three classic market moods:
Performance comparison: Index fund vs covered call ETF
A real-world example: Canadian banks
Let’s look at how this plays out in the real world using Canada’s big banks. If we compare a standard ETF holding Canadian bank stocks versus a covered call ETF holding those exact same bank stocks in the same proportion over a 10-year period, the difference in total wealth created is clear.
Over a full 10-year cycle, the standard bank ETF delivered a massive 392% total return for an average annualized return of 17.3% per year. The covered call version generated about 170%, or 10.4% annualized.

While the covered call ETF did exactly what it promised—it paid out steady monthly cash—the core value of the investment lagged behind. When the market dipped (like in 2020), the standard fund bounced back rapidly to new highs. The covered call fund struggled to climb out of the hole because its options contracts legally capped how high it was allowed to bounce back.
Final thoughts
Covered call ETFs are interesting financial tools, but they need to be used for the right reasons. They are designed for investors who prioritize consistent cash flows today over growing their wealth for tomorrow. This may fit retirees who need steady income to pay for their daily living expenses right now.
However, if you are still working, saving for retirement, or trying to grow your wealth over the next 10 or 20 years, these strategies might hold you back. By trading away your future growth for cash today, you put a ceiling on how much your nest egg can truly grow.
