ETF Post of the Week
The explosive growth of covered call and other options-based ETF strategies in recent years has been driven by investor appetite for high yields and enhanced income. As these products have multiplied, so too has the capital flowing into them. But lately, these strategies have come under increasing scrutiny for delivering disappointing after-tax performance.
QVR Advisors’ Benn Eifert puts it bluntly:
“Selling that call is just a trade. You’re going to lose money on that trade if the stock goes up enough. And if the stock is volatile—goes up a lot and then down a lot—you’re going to get hosed. Because when it goes down a lot, you just collect a small premium, but when it goes up a lot, you get your face ripped off. This is the precise nature of a short volatility trade.”
Morningstar’s Jeffrey Ptak adds:
“The manager can more-or-less choose the monthly or weekly distribution rate it likes. Then it’s a simple matter of multiplying that rate by twelve and dividing that product by the most recent NAV. Just like that, the ETF has a huge “yield”. But in most instances the income the ETFs earn from writing options falls far short of what’s needed to fund the distributions. Absent that, the ETFs are reliant on the stock to appreciate in order to plug the gap between the distribution rate the manager has set and the option income it’s collected. And on most occasions they’ve fallen short.”
At the core, critics highlight two main issues: 1) Chronic underperformance relative to the underlying stocks or benchmarks these ETFs track, and 2) High tax cost ratios, which further erode already-lagging returns.
A recent example from EconomPic on X illustrates the issue:
12-month returns thru 7/31/25:
Coinbase (COIN) +68%
YieldMax COIN Option Income Strategy ETF (CONY) +32%
After-tax pre-liquidation CONY -12%
These ETFs are doing exactly what they’re designed to do – harvest option premiums to deliver income. But that comes with tradeoffs: capped upside, significant tax drag, and often, underperformance. The real question is whether investors fully understand the structure – or are just chasing yield.
As Morningstar’s Amy Arnott reminds us:
“Ultimately, the famous quote from Legg Mason strategist Raymond DeVoe, Jr. bears repeating: More money has been lost reaching for yield than at the point of a gun.”
As of the end of July, there were 49 ETFs with a 1-year tax cost ratio* >10%.

ETF Chart of the Week
State Street’s latest ETF Impact Report is out and it comes with a prediction that global ETF assets could reach $54 trillion by 2035.
$54 trillion!
Assets currently sit near $15.5 trillion.
In other words, the ETF party is far from over – even with my bullishness on tokenization.
