NEW YORK, January 3, 2026, 10:41 ET — Market closed.
Shares of ACM Research closed up about 13.8% at $44.88 on Friday, outpacing the broader semiconductor rally on the first trading day of 2026.
The outsized move matters because it signals renewed risk appetite in smaller semiconductor names after a choppy end to December, with investors quickly rotating back into chip-related stocks as the calendar turned.
Chip stocks led the bounce, and the Philadelphia SE Semiconductor index rose about 4% on Friday. “Investors might be a little bit more conscious about some of the valuations that they’re paying for some of the AI plays,” Joe Mazzola, head of trading and derivatives strategist at Charles Schwab, said. 1
ACM Research makes tools used in semiconductor manufacturing, including equipment for cleaning and electroplating steps in chip production. 2
Moves were broad across the group, with semiconductor equipment peers also higher on Friday — Applied Materials gained about 4.6% and Lam Research rose about 8.1%, according to market data.
ACMR’s jump was sharper than the sector’s big-cap bellwethers, leaving traders debating how much of the move was a sector reset versus stock-specific positioning into the next company update.
The next scheduled catalyst is close: the company said it will publish a preliminary revenue range for fiscal 2025 and its initial 2026 revenue outlook before U.S. markets open on Jan. 22, and it will take part in the Needham Growth Conference on Jan. 15. 2
Investors typically look to those checkpoints for demand and customer commentary, especially in chip equipment where orders can swing quickly with capacity plans.
Before the next U.S. session on Monday, Jan. 5, attention will likely stay on interest-rate expectations and upcoming labor market data, which can move Treasury yields and, in turn, high-growth and semiconductor stocks. 3
On the chart, ACMR is sitting just below its 52-week high of $45.12; technical traders often watch that prior peak as “resistance,” or a level where selling can emerge, and look to the low-$40s as “support,” where buyers have tended to step in. 4
