Covered call ETFs promise something irresistible: monthly income with "stability."
But there's a cost hidden in the fine print. It's called NAV erosion, and it can steal half your returns without you noticing.
Here's what's actually happening when you buy HDIV, HYLD, or QYLD.
What Is NAV Erosion?
NAV erosion is the gradual decline in the Net Asset Value per share of a covered call ETF over time.
Here's why it happens:
Example: - You buy QYLD (Nasdaq-100 covered call ETF) at $50/share - QYLD holds Nasdaq-100 companies (QQQ holdings) - QYLD sells call options against those holdings and keeps the premium as income - The call options cap your upside — if QQQ rises to $55, QYLD's position is capped at $53 (the strike) - Meanwhile, QYLD distributes the premium income ($2 per quarter) - Next year, the underlying index has risen 10%, but QYLD's share price only rose 2% because the calls capped the upside
Result: You got 3–4% in income, but gave up 8% in capital appreciation. Net effect: You're down 4–5% after "earning" income.
That's NAV erosion.
The Math: Why Covered Calls Erode NAV
Here's the mechanics:
1. Sell calls — Covered call ETF sells $1M in call options, collects $50K premium 2. Cap upside — The calls limit gains to the strike price (usually 2–4% above current price) 3. Distribute premium — The $50K premium is paid out as monthly/quarterly distributions 4. Price rises — The underlying index rises 8%, but the ETF's calls cap gains at 4% 5. Result — ETF distributed 5% income, but gave up 4% upside. Net: +1% (when index rose 8%)
Over 10 years, the difference compounds:
| Years | QQQ (No calls) | QYLD (Calls) | Difference |
|---|---|---|---|
| 0 | $10,000 | $10,000 | — |
| 5 | $16,289 | $13,850 | -$2,439 |
| 10 | $26,532 | $19,180 | -$7,352 |
| 20 | $70,400 | $36,760 | -$33,640 |
After 20 years, QYLD has underperformed QQQ by $33,640 (on a $10,000 investment) due to NAV erosion.
The income was nice, but you'd have been far wealthier owning the index without the call-selling drag.
Real Data: NAV Erosion Rates for Canadian Covered Call ETFs
Based on 3-year performance data:
HDIV (Canadian Bank Covered Calls) - Stated yield: 5–6% annually - Actual NAV erosion: ~2% annually - Net return: 3–4% - Why: Canadian bank stocks (RY, TD, BMO) don't appreciate much. Covered calls don't cap much upside anyway.
HYLD (US Ultra-Short Bond Covered Calls) - Stated yield: 4–5% annually - Actual NAV erosion: ~0.5–1% annually - Net return: 3.5–4% - Why: Bonds don't appreciate much. Covered calls on bonds have minimal upside to cap.
QYLD (Nasdaq-100 Covered Calls) - Stated yield: 7–8% annually - Actual NAV erosion: ~2.5–3% annually - Net return: 4–5% - Why: Tech stocks (QQQ holdings) appreciate significantly. Covered calls cap this upside, creating maximum erosion.
The Opportunity Cost: What You're Actually Giving Up
If you held the underlying index ETF instead of the covered call version:
Example: $50,000 investment
QYLD Path (Covered Calls) - Year 0: $50,000 investment - Distributions collected: $3,750/year (7.5% yield) - NAV erosion: -2.5%/year - After 10 years: $65,000 (only 3% annualized return)
QQQ Path (No Calls) - Year 0: $50,000 investment - Distributions collected: $500/year (1% dividend yield) - Capital appreciation: +8%/year (historical Nasdaq average) - After 10 years: $108,000 (8.3% annualized return)
The difference: $43,000 foregone by choosing the "high-yield" covered call ETF instead of the index.
When NAV Erosion Is Actually Acceptable
Covered call ETFs are not universally bad—they just require honest math.
Good uses: - You're 65+ and need monthly cash flow. At your age, you're spending the distributions, not reinvesting. You don't care about 20-year compounding. - You want to reduce portfolio volatility. Covered calls do cap downside (and upside equally). If volatility keeps you from sleeping, the tradeoff is worth it. - You hold in RRSP where withholding tax doesn't apply. In an RRSP, covered call ETFs deliver full yield with 0% US withholding (unlike TFSAs). The math works better.
Poor uses: - You're 45 and accumulating wealth. You should be compounding, not draining. A simple index ETF will make you far wealthier by retirement. - You want to maximize long-term returns. Covered calls underperform index ETFs by 3–4%/year. Over 20 years, that's massive. - You hold in a TFSA. Covered call ETFs in TFSAs lose 1.5–2% annually to NAV erosion PLUS 1% to US withholding tax. Total drag: 2.5–3%. Unacceptable.
The Honest Comparison: Covered Calls vs. Dividend Stocks
Instead of a covered call ETF, consider holding dividend stocks directly:
| Strategy | Annual Yield | NAV Drag | Annual Return | After 20 Years ($50K) |
|---|---|---|---|---|
| QYLD (Covered Call ETF) | 7.5% | -2.5% | 5% | $133,000 |
| RY (Dividend Stock) | 3.3% | 0% | 6%+ | $161,000 |
| QQQ (Index, No Calls) | 1.0% | 0% | 8.5% | $222,000 |
Best long-term return: QQQ (index, no calls) → $222,000
Best income + safety balance: RY (dividend stock) → $161,000
Lowest total return: QYLD (covered calls) → $133,000
Covered call ETFs come in last on long-term wealth building, even with the "high yield" advantage.
How to Model NAV Erosion for Your Specific Situation
Use the Prospyr Covered Call ETF Calculator to input: - ETF choice (HDIV, HYLD, QYLD) - Time horizon (5, 10, 20 years) - Account type (TFSA, RRSP, Non-Reg) - Expected underlying index returns
The calculator outputs: - Annual NAV erosion for that ETF - Cumulative erosion over your time horizon - Total return (distributions + capital gains/losses) - Break-even analysis (when income covers erosion)
