How do Hamilton Yield Maximizer ETFs like HMAX and QMAX work?

A Hamilton Yield Maximizer ETF holds a basket of stocks and sells call options on some or all of it. It pays most of that premium out to you. In return, it gives up part of the big up months.

The short answer

HMAX and QMAX are two of Hamilton ETFs' "Yield Maximizer" funds. They trade on the Toronto Stock Exchange, in Canadian dollars. Each one holds a basket of stocks from one part of the market, which the fund's full name tells you. Then it sells Call options on that basket. As of October 2026, Hamilton says it writes them at or slightly above the price, on up to 100% of the fund, and changes how much to hit its target payout.

The buyers of those calls pay a premium. The fund collects it and pays most of it out to you as a regular payout.

That makes each one a Covered-call ETF. "Yield maximizer" is a fund name, not a promise. It means the fund is built to pay out a lot of cash. It says nothing about what you end up with after the share price moves.

This isn't a recommendation to buy or sell HMAX, QMAX or any Hamilton fund. Each fund's holdings and how much of it has calls written on it can change, so check the fund's page on Hamilton's site for the current numbers.

What "covered calls on part of the portfolio" means

Many Canadian covered call ETFs don't sell calls on every share they own. They write calls on some of the portfolio and leave the rest free.

That split is the most important number in the fund. Here's why:

• The part with calls on it earns premium but is capped. If those stocks jump, the fund keeps the move only up to the Strike price.
• The part without calls earns no premium, but it keeps the whole move up.
• Both parts take the full drop. The premium is a small cushion, not a floor.

Strike choice matters too. A call sold right at the current price pays the most premium and caps the hardest. One sold further above the price pays less and keeps more room.

The plain version of this trade is the covered call strategy. For how this fund type compares with JEPI, QYLD and YieldMax funds, see how covered call ETFs work.

A month worked out (hypothetical)

Here's the machine with made-up round numbers. This is an illustration, not a trade idea, and it isn't Hamilton's actual portfolio.

You put $10,000 into a made-up fund. It holds a basket of stocks worth $10,000. It sells one-month calls on half the basket, $5,000 worth, at the current price. It collects $150 in premium.

Compare that with just holding the basket: −$1,000, $0, +$400 and +$1,000.

The fund wins in a flat month. It loses a little less in a falling month. It trails in a strong month, by about half the gain minus the premium.

Where the payout comes from

The payout is mostly the premium from the calls. Some of it can be dividends from the stocks the fund owns.

If the fund pays out more than it earns, the difference comes out of the fund itself. The share price falls to match. Part of that payout may be labelled Return of capital: your own money handed back. That lowers your Cost basis, which Canadians track as adjusted cost base (ACB). See return of capital in covered call ETFs.

So look at two numbers together, never the payout alone:

1. The payout you received.
2. The share price from the day you bought to today.

Together they make the Total return. A big payout with a falling share price can add up to less than you put in.

CAD vs USD: what changes for a Canadian

These funds trade in Canadian dollars. That's handy in a Canadian account: no currency conversion to buy. As of October 2026, QMAX also has a US-dollar version, QMAX.U.

But some Yield Maximizer funds hold US stocks. When a Canadian-listed fund holds US stocks, its price in CAD moves with two things:

• The stocks themselves, in US dollars.
• The exchange rate. A weaker US dollar pulls the CAD value down. A stronger one pushes it up.

Some funds hedge the currency to remove that second effect. Some don't. Check whether the fund's name or page says "hedged".

A Canadian-listed fund that holds US stocks can also lose some US tax on the dividends it receives, inside the fund. And US-listed funds held in a TFSA face their own withholding rules. My page on US covered call ETFs in a TFSA works through that.

Accounts and taxes in Canada

Canadian-listed ETFs can generally be held in a TFSA, RRSP or a regular taxable account. Covered calls on your own shares are also widely allowed in a TFSA or RRSP, but options permissions differ by broker.

In a taxable account, a fund's payout can be a mix: dividends, capital gains, other income and return of capital. Each is taxed differently. The fund's T3 slip shows the mix each year. The CRA's pages on T3 slips explain each box.

Fund vs selling the calls yourself

A Yield Maximizer fund does the work for you. You don't need 100 shares, an options approval, or a calendar. That's the real value.

What you give up is control:

The drop is the same either way. The difference is who decides the cap. If you want to learn the trade the fund is running, the wheel strategy covers covered calls and the cash-secured put side together.
