Leveraged ETFs Explained: How TQQQ and SOXL Work and Why They Lose Value Over Time

TQQQ and SOXL are two of the most popular leveraged ETFs among American investors. TQQQ seeks three times the daily return of the Nasdaq-100 Index, and SOXL seeks three times the daily return of the NYSE Semiconductor Index. In a strong week for technology stocks, both can post gains that make ordinary index funds look slow.

The word that decides everything is daily. Because these funds reset their leverage every trading day, their returns over weeks, months and years can look very different from three times the index, and they can lose money even when the index they track goes up.

This guide explains how leveraged ETFs work, what happens inside TQQQ and SOXL, why they can lose value over time, what US regulators say about them, and the questions to ask before you consider one. FRC has no relationship with ProShares or Direxion and no stake in what you buy: we do not sell investments, manage portfolios or earn commission, so everything here is explained impartially.

What a Leveraged ETF Is

A standard index ETF aims to match the return of an index. If the Nasdaq-100 rises 1 percent in a day, a plain Nasdaq-100 fund rises by roughly 1 percent, before costs, because it simply owns the companies in the index. FRC’s dictionary entry on the index fund explains that basic structure.

A leveraged ETF is built to multiply the daily return of an index. A 2x fund aims for twice the daily return, and a 3x fund aims for three times. To do that, the fund uses derivatives such as swap agreements and futures contracts, alongside or instead of owning the underlying stocks.

There are also inverse ETFs, which aim for the opposite of the daily return, and leveraged inverse ETFs, which multiply that opposite. FINRA groups all of these together as non-traditional ETFs, because they behave very differently from the index funds most people know.

Leveraged ETFs trade on US exchanges and can be bought in an ordinary brokerage account, which is why they reach so many retail investors. If you are still learning how ETFs are structured and traded, FRC’s ETF Investing for Beginners course explains the fundamentals step by step, and Advanced ETF Investing goes deeper into specialised fund structures.

TQQQ Explained

TQQQ is the ProShares UltraPro QQQ. It seeks daily investment results, before fees and expenses, of three times the daily performance of the Nasdaq-100 Index. That index holds 100 of the largest non-financial companies listed on the Nasdaq stock market, with a heavy weighting towards large technology companies.

Because of that tilt, TQQQ is effectively a magnified, one-day bet on large US technology and growth stocks. When those stocks rise steadily, the fund can climb quickly, and when they fall, its losses arrive three times as fast.

ProShares also offers QLD, which seeks two times the daily return of the Nasdaq-100, and SQQQ, which seeks three times the inverse of the index’s daily return. SQQQ is designed to rise when the Nasdaq-100 falls, and it carries the same daily reset effects described below.

SOXL Explained

SOXL is the Direxion Daily Semiconductor Bull 3X Shares. Its summary prospectus states that it seeks daily investment results, before fees and expenses, of 300 percent of the daily performance of the NYSE Semiconductor Index. That index tracks US-listed companies that design, distribute, manufacture and sell semiconductors.

Semiconductor stocks are among the most volatile parts of the US market. Demand for chips rises and falls with technology spending, industrial cycles and global trade, and the sector can swing sharply on a single earnings report or policy announcement.

That makes SOXL one of the more extreme leveraged funds available to retail investors. It applies three times leverage to an already volatile, concentrated sector, so its daily moves can be very large in either direction. Direxion also offers SOXS, which seeks three times the inverse of the same index’s daily performance.

Why the Word Daily Changes Everything

Both funds describe their objective as a daily one. They aim for three times the return of a single trading day, measured from one market close to the next. They do not aim for three times the return over a week, a month or a year.

At the end of each day, the fund adjusts its exposure so that it starts the next day at three times leverage again. After a rise, it increases its exposure; after a fall, it reduces it. This rebalancing is what keeps the leverage at three times, and it is also what causes long-term returns to drift away from three times the index.

The SOXL prospectus says this plainly. It warns that investors who hold for periods longer or shorter than a trading day should not expect 300 percent of the index’s performance for that period, and that the fund can lose money even if the index’s performance increases over a period longer than a single day.

A Worked Example of Volatility Decay

Imagine an index starts at 100. On day one it rises 10 percent to 110, and on day two it falls 10 percent to 99. Over two days, the index has lost 1 percent.

Now take a 3x leveraged fund on the same index, also starting at 100. On day one it rises 30 percent to 130, and on day two it falls 30 percent to 91. The index lost 1 percent, but the leveraged fund lost 9 percent.

Nothing malfunctioned. The fund delivered three times the daily return on both days, exactly as designed, and the loss comes purely from compounding daily returns.

Extend that pattern over weeks of up-and-down trading and the gap widens. In a choppy, sideways market, an index can end a period roughly where it started while a 3x fund ends it noticeably lower. FRC’s dictionary entry on compound interest explains the maths of compounding that drives this effect in both directions.

When Compounding Works in the Holder’s Favour

There is another side to the story. In a strong, steady trend with little day-to-day volatility, compounding can work for a leveraged fund rather than against it.

Suppose an index rises 1 percent a day for five days in a row. It gains a little over 5 percent, while a 3x fund rising 3 percent a day gains a little over 15.9 percent, which is more than three times the index’s return. Smooth rising markets reward daily leverage.

That is why leveraged ETFs can post striking returns in some periods and attract attention on social media. The difficulty is that no one knows in advance whether the coming months will bring a smooth trend or a choppy market, and the same fund that outperforms in one can fall badly in the other.

Losses Are Magnified Too

Leverage works in both directions. If the index falls 10 percent in a single day, a 3x fund falls by roughly 30 percent, before costs.

A one-day fall of a little over 33 percent in the index would, in theory, wipe out almost the entire value of a 3x fund. Such a fall in a broad index in one day is extremely rare, but sector indexes like semiconductors move more sharply than the broad market.

Recovering from large losses is also harder than it looks. A fund that falls 50 percent needs to rise 100 percent just to get back to where it started, and a fund that falls 80 percent needs to rise 400 percent. Deep drawdowns in a 3x fund can take years to recover, if they recover at all.

What US Regulators Say

FINRA, the Financial Industry Regulatory Authority, addressed these products directly in Regulatory Notice 09-31. It stated that leveraged and inverse ETFs that reset daily typically are unsuitable for retail investors who plan to hold them for longer than one trading session, particularly in volatile markets.

The notice reminded brokers that they must understand these products and have a reasonable basis for any recommendation. Today, a broker-dealer recommending a security to a retail customer must also meet the SEC’s Regulation Best Interest, which requires the recommendation to be in the customer’s best interest.

FINRA also publishes investor guidance on non-traditional ETFs, explaining how daily resets and compounding can cause performance over longer periods to differ significantly from the stated multiple. These are not warnings about a single fund; they apply to the whole category.

Margin Rules for Leveraged ETFs

FINRA also recognised that leveraged ETFs carry more risk when bought with borrowed money. In Regulatory Notice 09-53, it raised maintenance margin requirements for leveraged ETFs in proportion to their leverage, with the requirement capped at 100 percent of the ETF’s value.

Under that approach, the standard 25 percent maintenance requirement for a long ETF position is multiplied by the fund’s leverage, so a 3x fund carries a 75 percent maintenance requirement. These rules now sit within FINRA Rule 4210, and individual brokers can set stricter requirements of their own.

Combining a 3x fund with margin borrowing stacks leverage on top of leverage. A modest fall in the index can then trigger a margin call, forcing a sale at the worst possible moment.

Costs Inside a Leveraged ETF

Leveraged ETFs usually charge higher expense ratios than plain index funds. On top of the published expense ratio, the fund bears financing costs on its swaps and futures, plus trading costs from rebalancing every day.

These costs are not always visible in a single line, but they reduce returns over time. Over a short holding period they may be small, while over many years they add up alongside the effects of volatility decay.

Always check the fund’s website for the current expense ratio, holdings, swap counterparties and risk disclosures. ProShares and Direxion both publish full prospectuses, fact sheets and daily holdings for each fund.

How Leveraged ETFs Are Taxed

In a taxable brokerage account, selling a leveraged ETF at a profit creates a capital gain. If you held the shares for one year or less, the gain is a short-term capital gain, taxed at ordinary income tax rates, which can be considerably higher than long-term rates.

Because leveraged ETFs are commonly used for short holding periods, many gains on them end up taxed as short-term. Leveraged funds can also make capital gains distributions in some years, which are taxable to shareholders even if they did not sell.

Inside an IRA, gains are not taxed each year, though using a retirement account for high-risk, short-term trading raises its own questions about whether the account is being used for its purpose. Your broker’s annual tax form shows how each distribution and sale is reported.

Who These Funds Were Designed For

Leveraged ETFs were designed mainly as short-term trading tools. Active traders use them to take a magnified view on a market for a day or a few days, or to hedge another position, and they monitor those positions closely.

Many US brokers ask customers to read and acknowledge a risk disclosure before trading leveraged or inverse ETFs. That step reflects the regulatory view that these are specialised products, not everyday investments.

For long-term investors building wealth through a 401(k), IRA or brokerage account, a low-cost broad market fund is built for the job a leveraged fund was never designed to do. FRC’s guide to Fidelity index funds explains how plain S&P 500 and total market funds work.

Common Mistakes With Leveraged ETFs

The first mistake is assuming a 3x fund will return three times the index over a year. It will not, except by coincidence, because the objective is daily and compounding changes the result over any longer period.

The second is buying and forgetting. A leveraged ETF held for months without monitoring can drift far from what the investor expected, and a large fall can be very hard to recover from.

The third is putting too large a share of a portfolio into one leveraged fund, and the fourth is adding margin borrowing on top. The fifth is choosing a fund because of a screenshot of recent gains, without reading the prospectus that explains how those gains were produced.

Questions to Ask Before Buying a Leveraged ETF

First, how long do you plan to hold it? If the answer is longer than a day or a few days, the fund’s own documents say its returns should not be expected to match the stated multiple.

Second, could you watch a 30 percent fall in a single day, or a 70 or 80 percent fall over a longer period, without being forced to sell? If not, the risk may not suit your situation.

Third, have you read the prospectus and understood how the daily reset works? Fourth, what share of your portfolio would this represent, and would you be borrowing to buy it?

Finally, check the fund’s website for current costs, holdings and risk disclosures. Figures change, and the official documents are the source to rely on.

Common Questions

Can you hold TQQQ long term? You can, but the fund seeks three times the daily return of the Nasdaq-100, not three times the long-term return. Over longer periods its returns can be much higher or much lower than three times the index, and FINRA says these products are typically unsuitable for retail investors holding longer than one trading session.

Why does SOXL lose value even when semiconductors go up? Daily rebalancing combined with volatility means losses on down days can outweigh gains on up days over time. SOXL’s prospectus states that the fund can lose money even if the index rises over a period longer than a single day.

Can a leveraged ETF go to zero? A 3x fund would lose almost all its value if its index fell a little over 33 percent in one day, and long, deep declines can reduce a fund to a small fraction of its starting value. Check each fund’s prospectus for how it handles extreme market moves.

Are leveraged ETFs the same as buying on margin? No. A leveraged ETF uses derivatives inside the fund, so you cannot lose more than you invest, while margin is money borrowed from your broker, where losses can exceed your original investment.

Is TQQQ better than QQQ? Neither is better in general. QQQ aims to track the Nasdaq-100 itself, while TQQQ aims for three times its daily return, which makes them very different products with very different risks.
