They Bought the Dip With 3x Leverage — Then the Dip Kept Dipping: SOXL's Record $6.1 Billion Bet Is Down 43% in October

Investors poured a record $6.1 billion into the Direxion Daily Semiconductor Bull 3X ETF (SOXL) last week, betting that the October chip-stock slide was about to reverse. Instead, SOXL fell another 10.8% this week — its third straight weekly decline — and is now down more than 43% in October, according to FactSet data reported by MarketWatch.

What happened

SOXL is a leveraged exchange-traded fund designed to deliver 300% of the daily move of a semiconductor index. As chip stocks slid through October on growing skepticism about returns from the AI infrastructure buildout, dip-buyers piled in at a record pace: $6.1 billion of inflows in a single week, the largest in the fund's history, per FactSet. The buying continued daily right up until Thursday — the day SOXL plunged 20.5% in a single session, its worst day since June 23, as semiconductor shares sold off sharply.

The key numbers

• Record inflows: $6.1 billion into SOXL last week (FactSet)
• This week: SOXL fell another 10.8% — a third straight weekly decline
• October damage: SOXL is down more than 43% this month
• Worst day: Thursday's 20.5% plunge was SOXL's biggest one-day drop since June 23
• Unleveraged comparison: the iShares Semiconductor ETF (SOXX) fell 6.8% on Thursday and is down about 15.9% in October — painful, but a fraction of the leveraged loss
• Still up big on the year: SOXX has gained almost 59% in 2026, which is why so many traders assumed October was just a dip

Why it's blowing up

The story has gone viral in finance circles because it is the year's cleanest example of leverage punishing a popular trade. Chip stocks have been the engine of the AI rally all year, and "buy the dip" has worked repeatedly in 2026 — so traders reached for the most aggressive tool available. But leveraged ETFs reset their exposure daily, which means a choppy, grinding decline hurts far more than the headline index move suggests. As MarketWatch put it: they tried to buy the dip, but the dip kept dipping. Bloomberg had already flagged the setup a week earlier, reporting that chip stocks had shed roughly $1 trillion in market value while billions flowed into semiconductor ETFs — including about $3.8 billion into SOXL in a single week even as it was falling.

Why are chip stocks falling at all?

The pressure is about AI spending, not chip demand. Investors are questioning whether the aggressive pace of AI infrastructure spending by tech giants will produce returns that justify today's valuations. "The semis have been so sensitive to the AI-infrastructure buildout," Mike Reynolds, vice president of investment strategy at Glenmede, told MarketWatch on Friday. "The AI trade has come under some skepticism here." Reynolds added that after such an aggressive rally, investors taking "a sober second look" is healthy. The weakness has been powerful enough to swing the whole market: the S&P 500's information-technology sector has now fallen for three straight weeks, its longest weekly losing streak since March.

What's next

All eyes now turn to next week's mega-cap tech earnings, when Microsoft, Alphabet and Meta report — the companies whose AI spending plans started this debate. Their guidance on capital expenditure will likely decide whether October's chip slide reads as a healthy reset or the start of something deeper. For SOXL holders, the math is unforgiving either way: after a 43% drawdown, the fund needs a gain of roughly 75% just to get back to even.

FAQ

What is SOXL?

SOXL is the Direxion Daily Semiconductor Bull 3X ETF, a leveraged fund that aims to deliver 300% of the daily performance of a semiconductor index. Because it resets daily, its long-term returns can diverge sharply from three times the index's return.

How much money flowed into SOXL, and what happened next?

Investors put a record $6.1 billion into SOXL last week, according to FactSet. Chip stocks kept falling anyway: SOXL dropped another 10.8% this week, including a 20.5% single-day plunge on Thursday, and is down more than 43% in October.

Why are semiconductor stocks falling in October 2026?

Investors are questioning whether massive AI infrastructure spending will generate returns that justify chip stocks' valuations after a huge 2026 run. The iShares Semiconductor ETF (SOXX) is still up almost 59% this year, but down about 15.9% in October.

Why did leveraged buyers lose so much more than regular chip investors?

SOXL targets three times the index's daily move, so repeated down days compound quickly. In October, SOXX fell about 15.9% while SOXL fell more than 43% — the leverage amplified every leg down.
