Tom Lee: Chip Selloff Is a Classic Buy-the-Dip Moment

Fundstrat's Tom Lee cites an 88% one-month recovery rate after steep semiconductor index drops, calling the latest chip selloff a textbook dip-buying opportunity for long-term investors.

Lead

Tom Lee, Head of Research at Fundstrat Global Advisors, stepped in front of the latest semiconductor rout on June 24 and called it an entry point. Appearing on CNBC, Lee pointed to a backtest showing that single-day drops of 6% or more in the VanEck Semiconductor ETF (SMH) and the iShares Semiconductor ETF (SOXX) have historically resolved higher one month later in 88% of cases, with a median recovery gain of 12%. The call came after the Philadelphia Semiconductor Index (SOX) had fallen more than 10% on June 4 — its steepest one-day decline since 2020 — erasing over $1.3 trillion in sector market capitalization.

What Happened

The selloff originated with Broadcom's (AVGO) third-quarter earnings release on June 3, when the company guided AI chip sales to $16 billion — below the $17.2 billion consensus estimate. The miss triggered an immediate "sell the news" reaction. Broadcom shares fell 14% in a single session, pulling the broader chip complex down with it.

A stronger-than-expected U.S. employment report released on June 5 deepened the rout. The data pushed Treasury yields higher, compressing valuations for high-growth technology names and sustaining selling pressure into mid-June. By June 23, the Philadelphia Semiconductor Index remained approximately 7.5% off its recent peak, and Micron Technology (MU) had extended its own losses by a further 10.8%.

Tom Lee's Thesis

The TomLee bull case rests on three pillars. First, history: his team's backtest identified 17 prior instances since 2011 in which semiconductor ETFs posted single-day declines of 6% or more. In 88% of those cases, the same indexes were higher one month later, implying the current episode fits a well-worn pattern of mid-cycle dislocations within longer bull markets rather than a structural break.

Second, valuations have quietly improved. S&P 500 forward earnings have risen by nearly $50 per share since January 2026, while the index's forward price-to-earnings multiple has compressed from 19 to 18. Lee argues that the broad equity market is in fact cheaper on a fundamental basis than it was six months ago, even accounting for the year-to-date rally.

Third, chips are not the source of the selling pressure. Lee identified the pending inclusion of SpaceX in the Nasdaq-100 as the primary mechanical driver of near-term liquidation.

The SpaceX Rebalancing Effect

Funds tracking the Nasdaq-100 — including the Invesco QQQ Trust (QQQ), which holds approximately $495 billion in assets — must mechanically purchase SpaceX shares at inclusion. Analysts estimate the combined forced buying across Nasdaq-100 and Russell trackers at $22–$27 billion. To fund those purchases, index managers must trim existing holdings, with heavily weighted semiconductor names bearing a disproportionate share of the selling.

Lee characterized this dynamic as temporary and structural rather than fundamental — a capital reallocation event that creates volatility without altering the underlying demand picture for chips.

Strategic Context

Underlying demand for advanced semiconductors remains intact. The AI infrastructure buildout continues to drive orders for high-bandwidth memory, advanced logic, and networking chips, with hyperscaler capital expenditure budgets for 2026 running well above 2025 levels.

Broadcom's guidance miss reflected a single-quarter revision, not a reversal in the broader AI chip procurement cycle. Industry checks since the earnings release indicate that data-center customers have not materially altered their procurement schedules, and the company's AI revenue trajectory over a rolling four-quarter view remains sharply higher.

The parallel pressures — a SpaceX-driven index rebalancing worth tens of billions of dollars, elevated rate sensitivity from a resilient labor market, and a single guidance miss at a major supplier — converged in the same fortnight, amplifying moves that historical context suggests are self-correcting.

Market Reaction

Following Lee's June 24 appearance, SMH and SOXX each gained, reversing a portion of the prior session's losses. Bargain buyers moved into Nvidia, AMD, and ASML Holding (ASML) intraday, though broader market sentiment remained cautious pending further clarity on the Federal Reserve's rate path and the mechanics of the SpaceX index inclusion.

Outlook

The semiconductor sector enters the second half of 2026 carrying significant near-term technical overhang from the SpaceX Nasdaq-100 rebalancing, expected to complete around early July. Once that mechanical selling exhausts itself, the sector's demand fundamentals — anchored in AI infrastructure, edge computing, and automotive electrification — reassert as the primary price driver. Tom Lee's 88% historical recovery rate following comparable selloff episodes underscores that chips have repeatedly absorbed sharp drawdowns without interrupting the underlying cycle. Whether the current episode follows that pattern hinges on AI capital expenditure remaining intact through the second half of the year, a precondition that, for now, the data supports.
