NEW YORK, January 4, 2026, 07:13 ET — Market closed
- ACM Research last closed up about 14% at $44.88 in Friday’s session.
- Semiconductor shares led a broader rebound to start 2026, lifting smaller chip-related names.
- Investors next look to ACM’s Jan. 15 conference meetings and a Jan. 22 revenue-and-outlook update.
ACM Research Inc (ACMR.O) shares last closed up about 14% at $44.88 on Friday, after trading between $40.26 and $44.99 on volume of roughly 1.66 million shares.
The move came as chip stocks led Wall Street’s first session of 2026 higher, with the Philadelphia Semiconductor Index up 4%, Reuters reported. “Investors might be a little bit more conscious about some of the valuations” in AI-linked stocks, Joe Mazzola, head of trading & derivatives strategist at Charles Schwab, told Reuters. 1
For ACM, the swing puts fresh attention on a near-term calendar that could shape expectations for 2026 demand. The company said it will release a preliminary revenue range for fiscal 2025 and provide an initial 2026 revenue outlook before the U.S. market opens on Jan. 22, and it will host one-on-one meetings during Needham & Company’s Growth Conference on Jan. 15. 2
A “preliminary revenue range” is an early estimate, not final audited results. An “outlook” is management’s first public view of what the next year’s sales could look like.
That matters for equipment suppliers because revenue outlooks often serve as a proxy for customers’ spending plans. Traders tend to focus on whether management signals expanding tool demand or a pause in orders.
ACM makes semiconductor process equipment, including tools for cleaning and electroplating steps used during chip production, as well as tools tied to advanced packaging. A wafer is the thin, round slice of silicon that chipmakers process into chips.
The broader equipment group also had a tailwind on Friday. ASML jumped after Aletheia Capital upgraded the stock, Investors.com reported, keeping investors focused on how quickly chipmakers may ramp capital spending this year. 3
With U.S. markets closed on Sunday, the next read on sentiment comes when trading resumes Monday. Semiconductor-linked stocks have been sensitive to shifts in risk appetite and any change in expectations around big customers’ 2026 spending.
Before the next session, chart-watchers will note that ACMR finished near the $45 area after testing lows around $40 on Friday. A break above Friday’s high would put the focus on whether buyers can sustain momentum; a pullback toward Friday’s low would test near-term support.
The next scheduled company moments are the Jan. 15 conference meetings and the Jan. 22 premarket update. Investors will be watching the tone on 2026 demand and any clues on how the company expects growth to track against the broader chip cycle.
