How Do Leveraged ETFs Work? The Promise Is Exactly One Day Long

A 3x fund does not promise you three times the index. It promises you three times the index’s return today, and then it makes the same promise again tomorrow, from a new starting point.

That distinction sounds pedantic until you have held one for a month. Every argument about these products, every warning label, and every surprised investor traces back to the fact that the objective in the prospectus is measured over a single trading day and the holding period in the account is not.

This piece is about how the machine works. Why a long hold diverges from the multiple you expected is a separate question with its own arithmetic, and it gets its own treatment.

What the fund actually owns

A leveraged equity ETF does not hold three dollars of stock for every dollar you gave it, funded by borrowing. Owning three hundred percent of anything in a fund is not permitted in the ordinary way, so the exposure is obtained synthetically.

The fund holds cash and cash equivalents, and it enters into total return swaps with bank counterparties, and often futures contracts alongside them. A swap is an agreement in which the bank pays the fund the return on a notional amount of the index, and the fund pays the bank a financing rate on that notional. The fund’s actual assets sit in Treasury bills earning interest, and the swap delivers the market exposure on top.

Will Rhind of GraniteShares gave the useful generalisation on Behind the Ticker: "all leveraged ETFs work the same." The instruments differ between issuers and asset classes. The structure does not.

Two consequences follow immediately. Because the exposure is contractual rather than owned, the fund carries counterparty risk to the banks on the other side, which issuers manage by spreading swaps across several. And because the swap notional is three times the fund’s assets while only those assets earn interest, a higher short rate is a net cost rather than a wash: the fund earns the rate on one dollar and pays it, plus a spread, on three.

The daily reset, and why it is not optional

Mo Sparks, Chief Product Officer at Direxion, described the mechanism in the plainest terms anyone has used on the show: these products "have a daily reset in them." The firm’s business, as he put it, is to "offer strategies that allow you to magnify your returns" over that daily window.

Here is why the reset has to happen, worked through with round numbers.

You put $100 into a 3x fund. The fund arranges $300 of index exposure. The index rises 3% that day. The exposure gains $9, so your $100 is now $109.

The fund now has a problem. It holds $309 of exposure against $109 of assets, which is 2.83 times, not 3. To honour tomorrow’s promise it must increase exposure to $327. So at the close it buys another $18 of exposure.

Now run it the other way. If the index had fallen 3%, your $100 would be $91, the fund would hold $291 of exposure against $91 of assets, or 3.2 times, and it would have to sell $18 of exposure to get back to $273.

Read those two paragraphs together and a real market behaviour appears. Leveraged funds buy exposure after markets rise and sell exposure after markets fall, mechanically, near the close, every single day. On a large move in a heavily traded index, that flow is measurable, and it is one of the reasons late-day momentum is a real phenomenon rather than folklore.

What the reset costs you

Because each day starts from a new base, returns compound off a moving number. Over a stretch where the index goes up and down and ends where it started, the fund does not end where it started.

Sparks acknowledged the gap between how the products are designed and how they are used, which is unusual candour from an issuer: he deals "with a lot of advisors that really don’t understand that, like, it’s a daily, and there is a decay" built in.

David Dziekanski of Quantify Funds, whose products are built specifically against this problem, named the two effects together when describing what he was trying to avoid: "leverage with less path dependency and potential for decay." Path dependency is the technical name. It means your result depends not only on where the index finished but on the order in which it got there.

The arithmetic of that deserves its own walkthrough, and we have given it one. For present purposes, the operating rule is: a leveraged fund tracks its multiple accurately over one day and approximately never over long periods, and the calmer the path, the closer the approximation stays.

Daily is a design choice

It is worth saying plainly that nothing about leverage requires a daily reset. A fund could reset monthly, quarterly, or at a fixed maturity, and some calendar-reset leveraged products now exist. Each reset window produces a different instrument, with different drift and a different sensible holding period.

Almost everything you will encounter resets daily, and that single design decision is what produces the behaviour described above.

Who these are built for

Sparks was direct about the intended user: the business has "been focused on creating tools for active traders to express" a view. He also placed the origin of the current lineup, noting the firm "launched our first ETFs in 2008 and 3X". The 3x funds were not a later addition. They were the launch.

That framing, a tool for expressing a short-term view, is the honest one, and not everybody in the industry thinks the tools belong in a client portfolio at all. Michael Monaghan, who launched the Founders 100 ETF, dismissed the category briskly: "double levered this triple inverse levered that they’re not investable."

Both positions can be held at once. A hammer is a good hammer and still the wrong thing to bring to a portfolio review.

Why there are no new 3x funds

If you have noticed that the 3x lineup looks like a fixed set from another era, that is correct.

Mike Venuto of Tidal put it flatly: "The odds that we ever see another 3x product right now under current law is pretty much zero."

The reason is Rule 18f-4, which governs how much risk a registered fund may take through derivatives. It caps a fund’s value at risk at 200% of a designated reference portfolio, or 20% of net assets in absolute terms, which a 300% exposure strategy cannot satisfy. Funds already operating above that level on 28 October 2020 were excepted, which is why the existing 3x lineup survives and nothing joins it. New leveraged launches, including the large crop of single-stock ones, come in at 2x or below.

What to check before you use one

The daily objective, stated in the prospectus, and the exact reference index. The reset frequency, which is daily unless the fund says otherwise, and if it says otherwise that is the most important sentence in the document. The financing cost embedded in the swaps, which is invisible in the expense ratio and rises with short rates. And your own intended holding period, measured honestly.

If the honest answer to the last one is longer than a few days, the arithmetic of path dependency is the thing to understand next, and it is worth an hour before it is worth a dollar.
