NEW YORK, Jan 4, 2026, 21:05 ET — Market closed
- Astera Labs shares closed Friday up 7.9% at $179.56, after trading between $170.30 and $182.88 on volume of about 5.7 million shares.
- An SEC filing showed company officer Philip Mazzara filed a Form 144 to sell up to 30,000 common shares, valuing the proposed sale at $4,990,800 and naming Morgan Stanley Smith Barney LLC as broker. 1
- Investors are heading into CES 2026 in Las Vegas (Jan. 6-9) and the U.S. jobs report due Jan. 9; earnings calendars list Astera’s next report around Feb. 9. 2
Astera Labs, Inc. closed sharply higher on Friday, outpacing the broader market on the first trading day of 2026 even as an insider sale notice flagged potential supply for the weeks ahead.
The timing matters because chip stocks have regained traction just as investors brace for catalysts that can quickly reprice risk appetite and interest-rate expectations. The Philadelphia Semiconductor Index closed up 4.01% on Friday at 7,367.47. 3
The insider filing is not a report of a completed sale. Form 144 is a notice filed when an affiliate plans to sell securities under Rule 144 above certain thresholds, the SEC says.
Astera Labs sells connectivity technology used inside AI and cloud data centers, positioning it among the smaller, higher-beta chip names that tend to move with sentiment around infrastructure spending.
For traders, Friday’s range set the early technical map for Monday’s open. A hold above the prior session’s low near $170 would keep the upside momentum intact, while the $183 area marks the first nearby ceiling.
But the stock’s move leaves little room for macro disappointment, especially with January data back in focus. “The market is looking for direction,” Matthew Maley, chief market strategist at Miller Tabak, told Reuters. 4
Markets will also be tracking the Federal Reserve’s January calendar, including the Beige Book on Jan. 14 and the Fed’s two-day policy meeting on Jan. 27-28. 5
Company-specific catalysts are thinner near-term, with earnings expected in early February and investors likely to focus on any shift in demand signals tied to hyperscaler buildouts and AI server deployments.
Monday’s session will show whether ALAB’s surge draws follow-through buying after the weekend, or whether the planned insider sale and a packed macro calendar cools the trade. The next hard date on traders’ screens is the U.S. payrolls report on Friday, Jan. 9.
