All Three Major U.S. Stock Indexes Extend Losses in Midday Trading; Philadelphia Semiconductor Index Falls 2.76%
0xBroomberg
US stocks extended intraday losses with the Philadelphia Semiconductor Index down 2.76% and Super Micro plunging over 18% on a $7 billion equity offering plan; Bank of America data showed investors dumped a record $10.8 billion in tech stocks last week, driven by institutional money.
Why did Super Micro suddenly crash 18%?
Super Micro fell 18.20% intraday, widening from 10.85% at the open.
The company announced a planned $7 billion equity raise to buy components needed to fulfill customer AI server orders.
This means → Super Micro's cash on hand cannot cover its backlog, so it is asking the market for money; equity offerings dilute existing shareholders, and the stock is paying the price.
How hard did the semiconductor sector get hit?
The Philadelphia Semiconductor Index fell 2.76%, extending losses from the open and becoming the session's main drag.
Individual names: Qualcomm −5.77%, Broadcom −4.94%, AMD −4.69%, TSMC −3.52%, Nvidia −2.91%, Intel −1.73%.
Memory chips were under pressure too, but diverged — Western Digital fell 5.62%, Micron −3.19%; SanDisk bucked the trend, up 1.38%.
In plain terms = almost the entire semiconductor chain sold off, from design to foundry to memory — virtually nowhere to hide.
How did Big Tech and compute-infrastructure names fare?
Most mega-caps declined: Amazon −2.08%, Meta −1.31%, Alphabet −0.78%, Microsoft −0.35%, Apple −0.15%.
Compute and data-infrastructure stocks stayed weak: Applied Digital −6.02%, Palantir −0.58%.
Oracle reversed an early 3% drop to trade up 0.19% — it reports earnings after the close, and the market is waiting for that scorecard.
A record $10.8 billion tech sell-off — where did the money go?
Bank of America data showed investors sold $10.8 billion in tech stocks last week — the largest weekly outflow since the bank began tracking in 2008.
Measured against S&P 500 tech-sector market cap, the outflow intensity hit its highest since 2014.
Clients sold a combined $14.2 billion in individual stocks last week, also a record; corporate buybacks as a share of market cap fell to their lowest since late 2023, with tech buybacks slowing the most.
This means → this is not just retail panic — large institutional money is the main seller, which matters more because institutional repositioning tends to last weeks, not days.
Are retail investors selling chips to fund SpaceX?
Some analysts suggested retail investors may be selling chip stocks to free up cash for SpaceX's Nasdaq listing on Friday.
Bank of America pushed back, noting that large institutional money — not retail — drove last week's tech sell-off.
In plain terms = the "retail raising cash for SpaceX" narrative sounds plausible, but the data does not support it as the primary driver.
What else on the macro front is weighing on the market?
US May inflation accelerated, though the core gauge rose less than expected month-on-month; economists still see room for further price increases, and a Fed rate hike this year remains a live possibility.
Geopolitical risk is also suppressing risk appetite — reports say Trump is "close to" ordering strikes on Iranian power plants and bridges.
On Tuesday, speculation emerged that a data-center build in Wyoming was paused, possibly signaling cooling AI compute demand.
This reflects a "triple headwind" hitting markets: sticky inflation + geopolitical uncertainty + wavering confidence in AI demand — and tech stocks are taking the first blow.
