If you owned Tesla stock on Thursday, you already had a rough day. If you owned a leveraged Tesla ETF, you had a really rough day.

Tesla (TSLA) shares cratered 14.5% in its worst single-day decline ever, wiping out $214.5 billion in market value. The trigger? A second-quarter earnings report that investors hated — not just because of the numbers, but because of what Tesla plans to do with all that cash.

But the pain didn't stop with plain-vanilla shareholders. A whole suite of leveraged single-stock ETFs that promise to deliver 2x the daily return of Tesla got absolutely hammered. We're talking losses approaching 30% in a single day. That's the kind of move that makes you question your life choices.

The Losers' List

Here's who got clobbered hardest on Thursday:

• T-Rex 2X Long Tesla Daily Target ETF (TSLT): down about 30%
• ProShares Ultra TSLA (TSLI): around 29%
• Direxion Daily TSLA Bull 2X Shares (TSLL): around 29%
• Leverage Shares 2X Long TSLA Daily ETF (TSLG): roughly 29%
• Graniteshares 2x Long TSLA Daily ETF (TSLR): about -29%
• Corgi TSLA 2x Daily ETF (TESC): 28%

Notice a pattern? They all lost roughly twice what Tesla did. That's by design — these funds use derivatives to deliver 2x the daily return of the underlying stock. When Tesla drops 14.5%, a 2x fund should theoretically fall 29%. And that's exactly what happened.

But here's the catch: the leverage resets every day. That means these funds are meant for short-term trading, not long-term holding. If you buy and hold a 2x leveraged ETF through a volatile period, the math can work against you in ways that aren't obvious at first glance. Thursday was a textbook example of the downside risk.

Why Tesla Got Punched So Hard

It wasn't just an earnings miss. Tesla's revenue actually beat Wall Street estimates. The problem was everything else.

Adjusted earnings came in below expectations as automotive margins weakened. More concerning, the company reported negative free cash flow for the first time in more than two years. Capital expenditures surged to about $5.8 billion in the quarter, and management said they'll exceed $25 billion in 2026 — and keep rising after that.

Where's all that money going? Robotaxis, Optimus humanoid robots, AI computing infrastructure, and next-generation manufacturing facilities. It's a massive bet on the future, but investors are starting to ask: when do these investments start paying off? Several analysts cut their price targets after the report, questioning the timeline for returns.

The market's message was clear: show me the money — or at least a credible path to it.

A Stress Test for Single-Stock ETFs

Tesla has always been a favorite among retail traders, so it's no surprise that there's a whole ecosystem of leveraged and inverse ETFs built around it. Thursday's action was a stress test — and it showed just how quickly these products can amplify losses around high-impact events like earnings.

These funds are designed for sophisticated investors who want short-term tactical exposure. They're not for grandma's retirement portfolio. When the underlying stock moves 14.5% in a day, a 2x fund can lose nearly a third of its value. That's the kind of volatility that separates traders from investors.

With Tesla likely to remain one of the most watched stocks in the AI and EV space, expect more wild swings — and more outsized moves in these leveraged ETFs. The ride isn't over yet.
