Leverage Decay Shock: The Powerful 91% MSTU Plunge Explained in 9 Clear Lessons
Leverage Decay Forced MSTU’s 91% Plunge: What Happened and What It Means for Traders
Summary: A leveraged ETF called MSTU—built to deliver 2x the daily move of MicroStrategy/Strategy stock (MSTR)—ended up falling about 91% over one year while MSTR fell about 53%. The big reason is leverage decay (also called volatility drag), which can quietly crush returns when markets are choppy.
1) What is MSTU, and why do people buy it?
MSTU is a leveraged exchange-traded fund (ETF) designed to provide 200% (2x) exposure to the daily price performance of MSTR. In simple terms:
If MSTR rises 1% in a day, MSTU aims to rise about 2% that same day.
If MSTR falls 1% in a day, MSTU aims to fall about 2% that same day.
People buy products like MSTU because they want a short-term turbo boost—often to trade big moves without using margin directly. But there’s a catch: MSTU is built for daily targeting, not for “buy and hold for months.”
MSTU is especially intense because MSTR itself is often treated as a Bitcoin proxy. The 24/7 Wall St. article describes MSTR as a “leveraged Bitcoin proxy” because the company holds a massive Bitcoin treasury (over 500,000 BTC, per the article). When Bitcoin moves, MSTR can swing even harder—and then MSTU amplifies that again.
2) The headline numbers: MSTR down 53%, MSTU down 91%
Here’s the eye-opener that made this story go viral in trading circles:
MSTR fell about 53% over one year.
MSTU fell about 91% over one year.
At first glance, you might think: “Wait—if MSTU is 2x, shouldn’t it be about 2x the loss?” But 2x daily is not the same as 2x over a year. Over long periods—especially with big volatility—returns can drift away from what you expect. That drift is often called leverage decay.
Even in a shorter window, the article points out “friction” from the daily reset. For example, year-to-date through mid-January, MSTR was up roughly 13% while MSTU was up about 23%—less than the “perfect” 2x math some people imagine.
3) Leverage decay in plain English (the “two steps forward, one step back” problem)
Leverage decay happens because leveraged ETFs:
Target a multiple of returns on a daily basis (not monthly, not yearly).
Reset their exposure every day to stay near that target multiple.
Are impacted by compounding in a way that depends on the path (the up-and-down sequence), not just the start and end prices.
Here’s a simple idea that trips people up:
If something goes down 10%, it needs to go up 11.11% to get back to even. Losses “weigh more” than gains of the same percentage. When you add leverage and daily resets, that math can become brutal in a choppy market.
Many investing education sources explain that leveraged ETF “decay” isn’t a mysterious fee—it’s a mathematical outcome that becomes worse with:
Higher volatility (bigger daily swings)
Longer holding time
Higher leverage (like 2x, 3x)
And MSTU checks the volatility box in a big way because it’s tied to MSTR, a stock that can swing hard when Bitcoin moves.
4) Why MSTU is a “triple-amplified volatility machine”
The article uses a striking description: if you own MSTU, you’re effectively betting on a stack of volatility:
Bitcoin volatility (crypto is famously jumpy)
MSTR volatility (a company heavily linked to Bitcoin’s price, plus corporate strategy and financing decisions)
MSTU volatility (2x daily leverage on top of MSTR)
That’s why the article frames MSTU as a tool for tactical traders, not a product meant to be held casually for months.
5) Bitcoin’s price levels: why $90K and $100K mattered in this story
According to the article, the “single macro factor” driving everything is Bitcoin’s next move over the coming months. It notes Bitcoin trading around $95,600 after testing resistance near $97,000, and mentions a pullback from November highs above $109,000.
The piece also highlights key “watch levels” traders follow:
$90,000 as an important support area (a break below could trigger heavier selling pressure)
$100,000 as a major psychological breakout level (a push above could fuel a sharp rally)
Because MSTU amplifies MSTR’s daily moves, a drawdown in Bitcoin can hit MSTU twice:
MSTR may drop if Bitcoin drops.
MSTU magnifies those daily drops—and the compounding can drag it down even more over time.
That’s the core danger: MSTU can lose value quickly in a messy market, even if you believe the long-term Bitcoin story.
6) The Polymarket angle: bullish… but not “easy mode” bullish
The article points to prediction-market probabilities on Polymarket as a way to show trader sentiment. It cites:
About an 88% probability Bitcoin reaches $100,000 by year-end
About a 51% chance it reaches $120,000
About a 63% chance Bitcoin dips to $75,000 at some point during the year
Even if the crowd is optimistic, those numbers scream one thing: volatility is expected. And volatility is exactly what can damage leveraged ETFs through decay.
Think of it like riding a bicycle on a road full of potholes. You might still reach the destination, but the bike can get wrecked along the way if it’s built too fragile.
7) February 5 earnings: why one date can shake a leveraged ETF
The article warns about an “outsized” event: MicroStrategy’s Q4 earnings on February 5 (after market close). Earnings can create sharp one-day moves because investors react fast to:
New financial results
Management guidance
Capital plans (borrowing, issuing shares, buying more Bitcoin, etc.)
It also notes that quarterly earnings growth fell about 77% year-over-year, a drop that investors would likely question.
Here’s why this matters extra for MSTU:
MSTR can swing wildly on earnings.
MSTU tries to double that daily swing.
If the move whipsaws across multiple days (up/down/up), decay can make the result uglier than you expect.
Key takeaway: With leveraged ETFs, a big calendar event isn’t just “a risk.” It can be a multiplier of risk.
8) “So… should I never touch leveraged ETFs?” Not exactly.
Leveraged ETFs can be useful when you treat them like what they are: short-term trading tools. Many educational sources warn that holding them long-term can be dangerous because of the daily reset and compounding effects.
That doesn’t mean they’re “bad.” It means they’re specific. Like a race car: amazing on a track, risky on a bumpy dirt road.
If someone uses MSTU, they should understand at least these basics:
Daily objective (not yearly objective)
Volatility drag can erase value fast
Single-stock concentration risk (MSTR isn’t an index; it’s one company)
Bitcoin linkage adds another layer of volatility

9) Alternative idea mentioned: BITX (and why it’s different)
The 24/7 Wall St. piece mentions BITX as an alternative for traders who want leveraged Bitcoin exposure without putting all the focus on a single company (MSTR).
Why might someone prefer a Bitcoin-focused leveraged product over MSTU?
MSTU is tied to MSTR, which has company-specific risks (earnings, strategy, financing choices).
BITX is presented as a way to get leveraged crypto exposure with less single-stock “headline risk.”

Practical “Reality Check” Guide: How traders think about MSTU
A) MSTU is about timing, not just direction
With normal investing, being right about the long-term direction can be enough. With MSTU, you can be “kind of right” about direction but still lose because the path matters. A volatile stair-step down can damage the ETF far more than you’d guess from the end result alone.
B) The market mood matters (smooth trend vs. chaotic chop)
Leveraged ETFs tend to behave “cleaner” in smooth, strong trends. They tend to behave “meaner” in back-and-forth chop. MSTR and Bitcoin often move in fast bursts, which increases the chance of chop and whipsaws.
C) Big headline days can dominate your result
Bitcoin news, regulatory headlines, macro events, and earnings days can create huge one-day moves. With daily-reset leverage, a few wild sessions can overpower weeks of calm.
FAQs (Leverage Decay, MSTU, and MSTR)
1) Why didn’t MSTU fall “only” 2x as much as MSTR?
Because MSTU targets 2x the daily return, not 2x the 1-year return. Over time, daily compounding plus volatility can cause leverage decay, making returns worse than a simple 2x expectation.
2) Is leverage decay a fee?
Not exactly. Decay mainly comes from math and compounding with daily resets. Fees and trading costs can add extra drag, but the “decay effect” can happen even before fees.
3) Can MSTU ever outperform 2x over a period?
Yes. In a strong, smooth uptrend, daily compounding can sometimes work in your favor. But in choppy or down markets, the same compounding can work against you.
4) Why is MSTU considered extra risky compared to many leveraged ETFs?
Because it leverages a single stock (MSTR), and MSTR is closely linked to Bitcoin, which is already volatile. So MSTU stacks volatility on volatility.
5) What key dates or catalysts did the article highlight?
It highlighted MicroStrategy’s Q4 earnings on February 5 and emphasized that Bitcoin’s price levels—especially around $90,000 support and $100,000 resistance—could heavily influence outcomes.
6) What’s a simpler way to reduce “single-stock risk” if I want Bitcoin exposure?
The article mentions BITX as one alternative for traders seeking leveraged Bitcoin exposure without concentrating the bet on one company’s stock behavior.
7) If I’m a long-term believer in Bitcoin, is MSTU a good long-term hold?
Many leveraged ETFs are not designed for long holding periods because of daily reset mechanics and volatility drag. If you’re thinking long-term, it’s worth learning how leveraged ETF compounding behaves and considering products that match long-term goals.
Conclusion: The real lesson from the 91% drop
The headline “MSTU plunged 91%” isn’t just a scary number—it’s a warning label about how daily leverage behaves in the real world. The 24/7 Wall St. article’s point is simple: if you hold a daily-reset leveraged ETF through a volatile, choppy, or declining period, leverage decay can punish you hard, even if the underlying asset doesn’t fall as much.
For traders, MSTU can be a powerful tool—but only if you respect what it is: a short-term instrument tied to an unusually volatile chain (Bitcoin → MSTR → MSTU). If you ignore that chain, the math can do the rest.
