Key Highlights

  • Entegris soared to $167.05 on Friday, having nearly doubled since the start of the year, with the gain tied to falling Treasury yields and cooling rate-hike expectations after the September jobs report; no company-specific announcement was found.
  • The company does not make chips itself but supplies ultra-pure specialty chemicals, filters, purifiers and wafer-handling containers used throughout the chipmaking process, benefiting as chips shrink and tolerance for contamination falls.
  • Chip-equipment peers KLA and Lam Research both climbed, and ASML rose ahead of its third-quarter results due in mid-October, while Teradyne was the best performer in the S&P 500.
  • A sharp drop in Seagate and Western Digital after a report on Toshiba's hard-drive capacity plans showed how fast sentiment can turn within AI hardware, a risk relevant to a stock that has rallied as hard as Entegris this year.

Entegris shares soared on Friday, trading at $167.05, as the chip-materials supplier rode a powerful rally across the semiconductor industry. NASDAQ:ENTG has now nearly doubled since the start of the year, making it a standout performer this year among S&P MidCap 400 members. The gain was tied to falling Treasury yields and cooling rate-hike expectations after the September jobs report. No Entegris-specific announcement was found.

The Picks and Shovels of Chipmaking

Entegris does not make chips. It makes what chip factories need to make chips: ultra-pure specialty chemicals, filters and purifiers that strip contaminants from liquids and gases, and the containers and carriers that move delicate silicon wafers through a fab without damage.

As chips shrink and become more complex, the tolerance for even microscopic contamination falls. That gives suppliers like Entegris a role in nearly every advanced Manufacturing step. Its sales tend to rise with the number of wafers being processed and with the complexity of each new chip generation, including the AI processors and high-bandwidth memory now in heavy demand.

Chip Equipment Joins the Party

Entegris had plenty of company among companies that Supply chip factories. KLA and Lam Research, two major chip-equipment makers, both climbed, and ASML rose ahead of its third-quarter results in mid-October. Teradyne, which makes chip-testing machines, was the best performer in the S&P 500.

The rally reached the biggest names too. Nvidia hit a record high during the session after Morgan Stanley named it its top semiconductor pick, and the Nasdaq-100 notched a record close at 30,807.93. The Nasdaq Composite rose 319.27 points to 27,190.86 after touching an all-time high during the day.

Information technology was the second-best S&P 500 sector, behind only consumer discretionary, which got a lift from Tesla's better-than-expected deliveries.

What Moved Rates

The Bureau of Labor Statistics said the economy added 29,000 jobs in September, far short of the roughly 84,000 economists had expected, and revised July and August down by a combined 60,000. Wage growth also slowed, with average hourly Earnings at $37.81.

Traders responded by slashing the odds that the Federal Reserve, which raised rates on September 16 for the first time since 2023, will hike again at its October 27-28 meeting. Those odds fell to roughly one in five after the report, from about two in three earlier in the week.

Jennifer Timmerman of Wells Fargo Investment Institute said the report showed renewed slowing in Job growth heading into the fall, potentially foreshadowing enough moderation in economic activity to delay additional Federal Reserve interest-rate hikes.

The Bond Market was less convinced. Yields dropped after the release and then reversed, closing higher on the day, with the 10-year yield near its highest level since 2002.

A Big Run Raises the Bar

Entegris has rallied hard this year. A run of that size tends to make a stock more sensitive to any hint that chipmakers are slowing spending on new capacity. Friday's sharp drop in Seagate and Western Digital, after a report said Toshiba plans to double its hard-drive capacity, showed how fast sentiment can turn within AI hardware.

ASML's Mid-October Results Will Set the Tone

ASML's mid-October results will offer the first big read on chip-equipment Demand for the quarter, and they often move the whole supply chain. Entegris's own report will show whether wafer volumes and AI-related demand are lifting materials sales. Beyond that, the Fed's October 27-28 decision and the direction of long-term yields will shape appetite for high-growth chip stocks.
