Right on Direction, Wrong on Money: How Leveraged ETFs Quietly Eat Your Capital

Why do you lose money even when you get the direction right?

Leveraged ETFs are built to multiply the daily move by two or three times — not the return over your holding period — and they reset every single day at the close. So when a market swings hard in both directions, you can come back weeks later to find the underlying flat and your balance down. That effect is called volatility decay.

During the recent 30-50% drawdown in semiconductor names, the people who got hurt worst weren't the ones who simply owned chip stocks. They were the ones who bet the same direction two or three times over through leveraged products.

My view is that these aren't so much dangerous products as products that are dangerous when sold without an explanation. The structure itself is honest. Most retail investors just don't know what that structure does.

What "resets daily" actually means

A regular ETF holds a basket of stocks. A leveraged ETF is different: it's engineered to track two or three times the underlying's one-day move.

On the way up it feels fantastic. The underlying rises 1%, you make 2-3%. What people forget is that it cuts both ways with equal force. Down 1%, you lose 2-3%.

The real trap starts here. Because the fund resets daily, gains and losses compound in a way that violates intuition. Look at the arithmetic.

Scenario	Underlying	3x leveraged
Day 1: -10%	100 → 90	100 → 70
Day 2: +11.1% (underlying back to par)	90 → 100	70 → 93.3
Net result	0%	-6.7%

The underlying came back exactly to where it started, and the leveraged product lost 6.7%. That's two days. In a market like this one, where single-day moves of 8-13% are routine, repeat that process for a month and the losses compound brutally.

Put differently: it is structurally possible to be right about direction over several weeks and still lose badly. That isn't bad luck. That's the product working as designed.

What actually happened in South Korea

The scariest real-world example came from South Korea, where these products had become wildly popular.

That market shrank from about $53 billion down to roughly half of that in a matter of weeks. One fund tied to a big memory chip maker reportedly lost around 80% in a single month. It got bad enough that government regulators had to step in and slam the brakes.

Line up the numbers again. When the underlying chip stock fell about 30%, the leveraged version was very nearly wiped out. The gap between 30% and 80% was filled by daily resets and volatility decay.

I'll be blunt here: that isn't investing. It's closer to gambling with dynamite.

Why retail investors specifically get hit hardest

There are structural reasons for this.

First, leveraged products trade most actively on assets that have already run up a lot. Which means most of the money enters near the top.

Second, during an uptrend the decay is almost invisible. When a trend runs one way, leverage actually works in your favor, so users learn the wrong lesson: "this product works."

Third, the ride down is always faster than the ride up — and leverage doubles or triples that speed too.

So retail investors learn when decay is weakest and pay when it's strongest. That's why these products keep producing the same outcome over and over.

If you're going to use them anyway, hold these lines

I'm firmly against using leveraged products as a long-term holding, and it's the same reason Warren Buffett and Charlie Munger have warned against them for decades. But they aren't banned, so at minimum I'd hold these lines.

• Cap your holding period in days. The product was designed around a single day. Structurally, there is no reason to hold one for months.
• Stay away when volatility peaks. Decay scales roughly with the square of volatility. The moment the market looks most exciting is the moment the product is most destructive.
• Set your loss limit as a dollar amount, not a portfolio percentage. Ask yourself whether you could absorb an 80% loss on that exact amount.
• Don't express conviction through leverage. If you're truly confident, sizing up the underlying is a far more honest way to say so.

The core point is simple. Finding a good company and choosing the instrument you use to own it are two entirely different decisions. Excellent judgment plus the wrong instrument still produces a devastating outcome.

If this resonates, my pieces on price versus value and disciplined investing and the philosophy behind price versus value go deeper on the same idea.

FAQ

Q: If I hold a 3x leveraged ETF for a year, do I get three times the underlying's return? A: No. The fund only replicates three times the daily return and resets each day. The longer you hold, the further actual returns drift from 3x — and in volatile stretches you can lose money even when the underlying finishes higher.

Q: Does volatility decay only happen in down markets? A: No. It comes from how much the asset swings, regardless of direction. Even with the underlying flat, heavy chop steadily grinds down a leveraged product's balance.

Q: If the underlying falls 30%, does a 3x product fall 90%? A: Not precisely — and in practice it's often worse. In Korea, a product tied to chip names reportedly lost about 80% during a stretch when the underlying fell roughly 30%, because decay stacks on top of the simple 3x math.

Q: So when does using one make sense? A: As a short hedge or a trade measured in days, it works as a tool. As a vehicle for long-term wealth accumulation, the design simply doesn't fit.
