SpaceX Frenzy Triggers Retail Fund Rotation Out of Chip Stocks
Alina Collins
Retail net selling of individual stocks hit its highest since November 2023, concentrated in semiconductor names like Micron and SanDisk, while space-themed buying surged to an 18-month peak — all driven by rising expectations of a SpaceX IPO.
Where is retail money leaving, and where is it going?
Vanda Research data shows retail investors are net-selling Micron (MU) and SanDisk (SNDK) most aggressively; semiconductors are the main source of outflows.
At the same time, retail buying of space-themed stocks hit a peak last seen in December 2024, closely tracking SpaceX IPO expectations.
This means → Retail isn't exiting the market — it's moving chips from "yesterday's story" to "tomorrow's story."
Is this a full-blown semiconductor exodus?
Not quite. Broadcom (AVGO) and Marvell (MRVL) are still drawing net retail inflows, showing that money hasn't abandoned chip stocks across the board.
In plain terms = Retail is selling consumer-memory chip names and keeping AI-infrastructure chip names — a structural rotation, not a systemic retreat.
What does the SOX flash-crash tell us?
On Tuesday the Philadelphia Semiconductor Index (SOX) plunged as much as nearly 9% intraday before paring losses to close down 1.9%.
The triggers were stacking up: SpaceX, OpenAI, and Anthropic are all expected to test public markets soon, on top of Alphabet's disclosed $80 billion equity financing plan. Sensitivity to new-share supply spiked.
This reflects a market pre-positioning for liquidity strain — even before any of these mega-IPOs actually prices.
Is the IPO supply shock really that scary?
Macro strategist Alfonso Peccatiello, citing a Goldman Sachs chart, argues that IPO impact should be measured as new issuance relative to Russell 3000 total market cap, not in raw dollar terms.
By that yardstick, "equity issuance as a share of total market cap is still very small"; the historical track record of using IPO waves to call market tops is "pretty terrible."
In plain terms = The dollar figures look alarming, but relative to the whole market they're modest — an IPO wave alone is unlikely to end the bull run.
Has the rate-hike narrative gone off the rails?
After last Friday's stronger-than-expected payrolls, markets revived rate-hike bets and chip stocks came under pressure.
Peccatiello argues that narrative may have "gotten out of hand": if higher rates reflect stronger nominal growth, the impact on risk assets is fundamentally different from the Fed actively hitting the brakes.
This means → Higher rates ≠ bearish by default. What matters is *why* rates are higher — a hot economy versus a restrictive central bank. Chip stocks behave very differently in each scenario.
How long can this fund-flow diversion last?
The IPO supply wave probably can't derail the broader bull market, but it is enough to divert retail attention away from existing chip proxies at the margin.
Whether this diversion persists depends on the actual timing of SpaceX and other mega-IPOs and how well the market absorbs them.
Put simply = Retail wallets are finite; more new listings mean less attention for old holdings — but only if those IPOs actually land.
