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 SOXL last week, betting that beaten-down chip stocks were about to bounce. Instead the dip kept dipping: the 3x leveraged semiconductor ETF fell another 10.8% this week — its third straight weekly loss — and is down more than 43% in October, including a 20.5% single-day plunge on Thursday.

What happened

The Direxion Daily Semiconductor Bull 3X ETF (SOXL) is designed to deliver three times the daily move of a semiconductor index. When chip stocks wobbled earlier this month, dip-buyers treated that leverage as an opportunity: the fund took in a record $6.1 billion in a single week, according to FactSet data reported by MarketWatch and Morningstar, with money still flowing in daily through Thursday.

Thursday is when the bet broke. Semiconductor stocks sold off sharply as skepticism grew about whether the enormous spending on AI infrastructure will produce returns to match. SOXL plunged 20.5% in that one session — its largest single-day drop since June 23 — while the unleveraged iShares Semiconductor ETF (SOXX) fell 6.8% the same day. For the week, SOXL lost 10.8%, its third consecutive weekly decline, and its cumulative October loss passed 43%. SOXX, by comparison, is down about 15.9% in October.

Why it's blowing up

Partly it's the sheer size of the mistimed bet: a record inflow, in a single week, into one of the most aggressive retail instruments in the market, immediately before its worst day in four months. Partly it's what the bet was about. Chip stocks have been the engine of the AI trade — SOXX was up nearly 59% year-to-date at its peak — so a leveraged bet on their rebound was effectively a leveraged bet that AI spending skepticism is overdone.

Strategists framed the selloff as a reassessment rather than a collapse. "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." The broader market felt it too: the S&P 500's information technology sector has now fallen three straight weeks, its longest losing streak since March.

Key facts

• Record inflow: $6.1 billion into SOXL in one week — the most in the fund's history (FactSet).
• This week: SOXL −10.8%, its third straight weekly decline.
• October: SOXL down more than 43%; SOXX down about 15.9% over the same stretch.
• Thursday's hit: SOXL −20.5% in one day, its worst session since June 23; SOXX −6.8%.
• The driver: growing skepticism about returns on AI infrastructure spending, after a run that had SOXX up nearly 59% year-to-date at its peak.
• Friday: SOXL steadied, closing up about 1.8% at $83.56 — though still roughly 99% year-to-date in a year that shows both sides of 3x leverage.

Why the leverage cuts so deep

SOXL's 3x promise applies to a single day, because the fund resets its leverage daily. In a choppy, falling market that design works against holders even when the underlying index later recovers: each down day compounds from a smaller base, and each up day has to be three times as large just to keep pace. That is how an index down about 16% in a month becomes a fund down more than 43% over the same period — the gap between the two numbers is the cost of daily-reset leverage in a volatile slide, and it is the reason these funds are built for short-term trades, not for riding out a correction.

What's next

The next test is earnings: the chip and AI-infrastructure names reporting in the coming days will either validate the spending boom or deepen the skepticism driving this selloff, and SOXL holders will feel whichever way it goes at triple strength. The inflow data will also be telling — whether last week's record dip-buying was a one-week capitulation trade or the start of a longer standoff between retail conviction and institutional caution.

FAQ

What is SOXL and why did it fall 43% in October?

SOXL is the Direxion Daily Semiconductor Bull 3X ETF, which aims to deliver three times the daily move of a semiconductor index. Chip stocks sold off in October on skepticism about AI spending returns — the unleveraged SOXX fell about 15.9% — and SOXL's daily-reset 3x leverage amplified that into a loss of more than 43%.

How much money flowed into SOXL before the drop?

A record $6.1 billion in a single week, according to FactSet — investors buying the dip right up until Thursday, when the fund plunged 20.5% in its worst day since June 23.

Why does a 3x ETF fall more than 3 times its index over a month?

Because the leverage resets daily. In a volatile decline, losses compound from a shrinking base while gains must be proportionally larger to recover, so the fund's multi-week return can be far worse than three times the index's return over the same period.

Did SOXL recover on Friday?

Only slightly: it closed up about 1.8% at $83.56 on Friday, October 23, after Thursday's 20.5% plunge left it down 10.8% for the week and more than 43% for October.
