Leveraged ETFs are some of the most misunderstood products a regular investor can buy. They promise two or three times the daily move of an index, wrapped in something as easy to trade as a single stock, with no margin account and no options to manage. That promise is real. The catch lives in one small word: daily. This post explores how leveraged ETFs work, why a 3x fund can fall behind the very index it tracks even when that index rises, the genuine reasons these funds exist, and the things worth thinking through before holding one, including a couple that matter specifically to Canadians.
What is a leveraged ETF?
A leveraged ETF is a fund that aims to multiply the daily return of an index. A 2x S&P 500 fund tries to return twice whatever the S&P does on a given day. A 3x Nasdaq-100 fund, like TQQQ, aims for three times the Nasdaq-100’s daily move. There are inverse versions too: a -1x or -3x fund is built to go up when the index goes down.
Here is the part that surprises most people. These funds usually do not hold the stocks in the index at all. To get 3x exposure efficiently, the manager mostly uses derivatives, total-return swaps and futures, with a counterparty on the other side of the trade. Issuers like Direxion, ProShares and Global X all build their leveraged products this way. You buy and sell the ETF like any stock, but under the hood it is a stack of daily contracts, not a basket of shares.
How the daily reset works
The single most important word in any leveraged ETF’s description is “daily.” The fund targets a multiple of the index’s return for one trading day, then resets.
To keep delivering 3x against a moving market, the fund rebalances its exposure at the end of every session. On a day the index rises, it effectively adds exposure for the next day. On a day the index falls, it cuts exposure. In plain terms, it buys after up days and sells after down days, every single day, mechanically. For a one-day holding period that is exactly what you signed up for. Over weeks and months, that constant resetting against a changing base is where the math quietly turns against you.
Volatility decay: the cost of holding past a day
This is the concept that catches people off guard, so it is worth walking through slowly with real numbers.
Imagine an index that rises 10% one day and falls 9.09% the next. Do the arithmetic and the index is essentially flat over the two days (1.10 times 0.9091 is back to about 1.00). Now run a 2x fund through the same two days, starting at $100:
- Day 1: the index is up 10%, so the 2x fund is up 20%. Your $100 becomes $120.
- Day 2: the index is down 9.09%, so the 2x fund is down 18.18%. Your $120 falls to about $98.20.
The index finished flat. The 2x fund finished down almost 2%. Nobody made a mistake, no fee did that. It is purely the result of taking a percentage move on a base that keeps changing. Stretch that over a year of back-and-forth markets and the drag compounds. This is volatility decay (sometimes called volatility drag), and it is the reason leveraged ETFs behave so differently over time than the “3x” label suggests.
It also gets worse faster than you would expect. The effect scales with the square of the leverage, not in a straight line. Roughly speaking, a 3x fund decays about 2.25 times as fast as a 2x fund on the same index. In calm markets the drag on a broad 2x fund might only be a percent or two a year. On a volatile 3x fund it can run well into the double digits, and in a genuinely turbulent year it can be far worse than that.
The takeaway: sideways and choppy markets are the enemy. A leveraged ETF can lose money over a period where the index itself goes nowhere. If you understand only one thing about these funds before buying one, make it this.
Why leveraged ETFs exist
For all that, they are not a trap, and they solve a real problem. The benefits are worth stating plainly:
- Capital efficiency. You get 3x exposure with roughly a third of the cash, freeing up the rest for other things.
- No margin loan. The traditional way to lever up is to borrow money, which means interest payments and the risk of a margin call forcing you to sell at the worst moment. A leveraged ETF bakes the leverage in, and the most you can lose is what you put in.
- Simplicity and access. You can buy one in an ordinary brokerage account, like any stock, with no special approvals.
- Clean tactical exposure. For someone with a short, deliberate view (a day, a few days), a leveraged ETF is a precise tool for expressing it.
None of this makes them suitable for everyone. It makes them useful for a specific job.
The risks that go beyond decay
Volatility decay is the subtle risk. These are the blunt ones:
- Magnified losses. A 3% drop in the index is roughly a 9% drop in a 3x fund. Double-digit single-day swings are normal in volatile stretches, and a severe or prolonged downturn can erase 90% or more of a leveraged fund’s value. That is not a worst-case scare; it has happened.
- Higher fees. More moving parts means higher management expense ratios than a plain index ETF. The cost is small per year but it stacks on top of the decay.
- Counterparty risk. Those swaps depend on a counterparty making good on its side. Funds collateralize to manage this, but it is not zero.
- They are not built to hold. The issuers say so themselves, in plain language, in their own marketing. When the product’s own maker tells you it is for short-term, tactical use, that is worth believing.
TQQQ vs TQQQ.TO: same ticker, different fund
If you are Canadian and you have gone looking for TQQQ, you may have hit a confusing wall: there appear to be two of them. That is because there are.
- TQQQ on the US market is the ProShares UltraPro QQQ, a 3x Nasdaq-100 fund priced in US dollars.
- TQQQ.TO on the Toronto Stock Exchange is a different fund entirely: the BetaPro (by Global X) 3x Nasdaq-100, and it is currency-hedged to Canadian dollars.
Same three letters, different issuer, different currency treatment. The Canadian version aims to strip out the US-dollar swings, so you are betting on the Nasdaq rather than on the loonie at the same time. For a Canadian, that hedging removes one variable, though it is still a 3x leveraged product with all the decay and drawdown risk above.
A note on registered accounts (TFSA and RRSP)
This one matters, and it runs against most people’s instinct. It is tempting to put a high-octane holding in a TFSA so any gains come out tax-free. With a leveraged ETF, that logic can backfire, and many Canadian investors deliberately keep these out of registered accounts for two reasons:
- A large loss in a TFSA permanently destroys contribution room. Say you put $7,000 into a TFSA and a leveraged position falls to $2,000. The $5,000 is simply gone, and you do not get that room back. New room is added on a yearly schedule, and only withdrawing the remaining value adds room back the following year. The loss itself never returns as room.
- You cannot claim the loss on your taxes. In a non-registered (taxable) account, a capital loss can offset capital gains and soften the blow at tax time. Inside a TFSA or RRSP, a loss is just a loss, with no tax benefit at all.
So the very feature that makes leverage dangerous, fast and deep losses, does the most damage exactly where Canadians most want to shelter their money. This is a general consideration, not advice for your situation, and it is worth a conversation with a tax professional before you act on it.
Can you hold leveraged ETFs long term?
The honest answer, from the way they are built, is that they are designed for a single day. Hold one through a long, smooth uptrend and it can do spectacularly well, because in a steady climb the daily resetting works in your favour and compounds gains. Hold the same fund through a choppy or falling market and decay plus a deep drawdown can hollow it out. The catch is that you do not get to choose which kind of market shows up next.
Some investors try to square this circle with rules: hold the leveraged fund while the trend is up, and rotate into cash or short-term Treasuries when it turns down. That is the idea behind the TQQQ-BIL strategy, which you can backtest on this site, and a Canadian version built on TQQQ.TO and CASH.TO. Whether that kind of rotation beats simply holding the fund is its own question, which this post on the TQQQ-BIL strategy digs into. If you want to see exactly how those backtests are built and what they leave out, the methodology page lays it all out.
Bottom line
If you are going to use leveraged ETFs, three pieces of homework matter most. First, make sure you genuinely understand how the daily leverage reset and volatility decay work, because those two mechanics drive everything else on this page. Second, backtest the strategy across different market conditions, a flat year and a crash and not just the bull run you happen to remember, so you see how it behaves rather than how you hope it will. Third, be honest with yourself about risk tolerance: a strategy only works if you can stomach holding it through a 2022-style drawdown instead of bailing at the bottom. If any of those three gives you pause, that is useful information too. Educational only, never a recommendation.
