New York, Jan 21, 2026, 11:42 a.m. EST — Regular session
- By 11:32 a.m. EST, Rambus had climbed roughly 18% to $130.26, after hitting an intraday high of $130.90.
- Chip stocks climbed across the board, led by the iShares Semiconductor ETF, which gained roughly 3%. Intel, AMD, and Micron also saw notable jumps.
- Investors are eyeing Rambus’ Feb. 2 earnings call, seeking any updates on guidance linked to data-center memory demand.
Rambus Inc shares surged roughly 18% on Wednesday, hitting a fresh 52-week peak amid a broader semiconductor sector rally.
This matters since Rambus, a smaller, high-beta player in the chip space, has seen its stock surge, setting higher expectations for the upcoming earnings report. When shares jump sharply like this, the next guidance often weighs heavier than the actual earnings figures.
Chip stocks surged across the board. Intel climbed roughly 11% by late morning, AMD rose about 8%, and Micron gained close to 8%. The iShares Semiconductor ETF was up around 3%.
“That’s really the big Intel bull case,” said Ryuta Makino, analyst at Intel investor Gabelli Funds, highlighting expectations for higher server CPU prices this year. Meanwhile, UBS analysts warned in a separate note that rising memory costs could dampen PC demand, even as data-center demand remains strong. (Reuters)

Rambus started the day at $120.81 before dipping to $111.50, then surged to an intraday peak of $130.90. By late morning, roughly 2.8 million shares had changed hands.
The company will report its fourth-quarter and full-year results on Feb. 2 at 2:00 p.m. Pacific time, according to a statement announcing the call. (Rambus)
Rambus investors are probably paying more attention to the company’s outlook on demand for server memory components and how quickly newer standards like DDR5 are being adopted, rather than last quarter’s revenue figures. DDR5, a faster type of memory, is increasingly common in the latest servers.
But the setup works both ways. A stock surging to a new high before earnings can still take a hit if the outlook is cautious or margins slip due to product mix, pricing shifts, or timing with customers—even if the results themselves are solid.
Traders are gearing up for Thursday’s major chip earnings, eyeing clues on server build trends and memory pricing. Then, Rambus takes the spotlight again with its February 2 call, where management’s comments will likely steer the narrative.
