Chip Stocks Fell 4.5% on a Hot CPI Day While ASML Said Demand Will Outrun Its Factories Through 2028: What Happened After the Last 107 Chip Selloffs

Chip stocks had their worst day in a month on Wednesday, October 14, and the trigger was not a chip company. The September CPI report at 8:30 AM showed inflation at 3.7% with core at 2.6%, both a tenth above forecast, per the BLS release as reported by CNBC. Treasury yields rose, the 10-year to 5.27%, and the stocks that depend most on cheap money and long time horizons sold off. The iShares Semiconductor ETF, SOXX, closed down 4.5%. Nvidia fell 3.2%, Micron 4.1%, and the Nasdaq lost 1.9% against 1.1% for the S&P 500 and 1.9% for the Russell 2000, per Yahoo Finance's market coverage.

The strange part is what the chip industry itself said the same morning. ASML, the only company that makes the lithography machines every advanced chip needs, reported a record quarter and told investors that demand will exceed everything it can build through 2028. Its U.S. shares closed down 3.9% anyway. That combination, record fundamentals and a falling stock, is the question this post is about, and we put a number on it: what the chip index did after every one of its previous 107 selloffs of 4% or more.

What ASML actually reported

From ASML's third-quarter release, filed with the SEC on October 14: total net sales of 11.7 billion euros, a record and toward the high end of its own guidance, a 57.5% gross margin, and net income of 5.0 billion euros. Fourth-quarter guidance is 14.2 to 15.2 billion euros of sales, and the full year is now 44 to 45 billion. The company bought back about 4.1 billion euros of shares in the quarter and pays an interim dividend of 1.88 euros a share on November 4.

The sentence that matters is in the CEO statement: with an order book "that continues to increase quarter on quarter," ASML now expects that its planned supply "for both 2027 and 2028 will not fully meet the demand of our customers," and it is studying how to add capacity for 2028 beyond the 30% increase it had already announced. Some customers are asking to place orders for 2029 and 2030. For the AI build-out, that is as direct a statement of demand as the supply chain produces. The stock fell because the day was about the discount rate, not about ASML, and because a memory-chip scare out of Asia earlier in the week had already put the sector on edge. TSMC reports Thursday at 2 AM Eastern with a record quarter of its own already visible in its monthly sales.

What happened after the last 107 chip selloffs

We took every trading day since SOXX's history begins in November 2011 on which the ETF fell 4% or more from the prior close, using daily closes from Yahoo Finance, and measured where it stood 1, 5, 20 and 60 trading days later. There were 107 such days before Wednesday. Two things stand out.

• 2026 is already the most volatile year for chips on record. Wednesday was the 22nd 4% down day this year, passing 2022's 21, the previous record, and 2020's 14. Eight of them came in July alone.
• On average the index was higher afterward, but the average hides the clusters. The median move the next day was +0.8% (up on 69 of 107), +2.4% after five days (up 68 of 107), +4.0% after 20 days (up 72 of 107), and +8.8% after 60 days (up 80 of 107).
• The bad clusters are where the money is lost. Selloffs come in runs: 21 in 2022, 14 in the spring of 2020, eight in July 2026. Inside a run, one 4% day is often followed by another. Of July's eight, the 20-day outcomes ranged from -15.9% to +10.8%. A single-day signal says almost nothing about whether you are at the start of a run or the end of one.
• The biggest drops were the best entries, in hindsight only. The three largest, March 16 and 12, 2020 (down 15.2% and 11.0%) and June 5, 2026 (down 10.4%), were followed by 20-day gains of 30.1%, 15.4% and 2.3%. Nobody buying those days knew that.

The honest reading: a 4% chip day has been a better buying day than selling day on average since 2011, a period that includes the longest bull market in chips in history, and that average is made of a few spectacular rebounds and many dull ones. It is not a signal, and 2026 has produced it more often than any year on record, which is itself the information.

What it means for the next two weeks

• The Fed is the overhang, not the chips. Hot CPI pushed up the odds of another hike even if the committee pauses on October 28; Yahoo's coverage cited about 78% of investors still expecting a hold. Our Fed meeting preview covers what stocks did after every pause since 1994.

The same session also hit the AI borrowers: Oracle fell 8.8% and CoreWeave 15.5% as yields on their debt jumped. Every 8% Oracle drop since 1986, and what came 60 days later is the companion read.

• Thursday is the test. TSMC's results and guide at 2 AM Eastern, then producer prices and retail sales at 8:30. If TSMC's capital-spending number matches ASML's language, the demand story is intact and the selloff was about rates. If it does not, the memory scare gets a second act.
• Size for runs, not days. Twenty-two 4% days in ten months means a chip position should be sized so that three of them in a week is survivable. Position sizing that treats a 10% drawdown as ordinary is the whole game in this sector this year.
• Do not confuse the stock with the business. ASML's day is the cleanest example you will see of a record quarter and a red close. If you hold chips on a thesis about AI demand, Wednesday did not change the thesis. If you hold them on momentum, it did. Rules written before the day are what separate the two.

If you would rather have those rules applied for you, with stops and position caps enforced inside your own brokerage account, that is what JorgAI does. You can set them up before Thursday's open.

Quick answers

Why did chip stocks fall on October 14, 2026? A hotter-than-expected CPI report (3.7% headline, 2.6% core) pushed Treasury yields and rate-hike odds higher, which hits long-duration growth stocks hardest, on top of a memory-chip scare earlier in the week. SOXX closed down 4.5%.

Did ASML beat earnings? Sales of 11.7 billion euros were a record and at the high end of guidance, net income was 5.0 billion euros, and the company raised its full-year outlook to 44 to 45 billion euros. It said demand will exceed its planned supply in 2027 and 2028. The U.S. shares still closed down 3.9%.

What happens after a 4% drop in chip stocks? Across the 107 such days since 2011, the SOXX ETF was higher 20 trading days later 72 times, by a median of +4.0%. The exceptions cluster in bad years, and 2026 has now produced 22 such days, the most on record.

Will the Fed raise rates in October 2026? Markets still lean toward a pause on October 28, with hike odds higher after CPI. The decision comes two days before the September PCE report.
