On June 12, Astera Labs rose 4.77% in regular trading, trading at $376.61/share, with turnover of $222 million. The rally was driven by the announcement that the company has been selected for inclusion in the Nasdaq 100 index as part of its quarterly rebalancing.

Nasdaq published its quarterly adjustment results on the same day, confirming Astera Labs will join the benchmark index alongside CoreWeave, NEBIUS, Rocket Lab, and Teradyne, with the change set to take effect before market open on June 22. Index inclusion typically triggers mandatory allocation by passive index-tracking funds, driving concentrated short-term capital inflows into the stock.

The positive catalyst builds on recent fundamental tailwinds, including the company's expansion of its Taiwan operations and cloud-scale interoperability laboratory, deepening collaboration with major AI platform vendors such as AMD, Arm, Intel, and NVIDIA to accelerate AI infrastructure validation and system integration. Management previously disclosed that its chips and optical solutions are now integrated into nearly 90% of global AI computing clusters, with the Scorpio X series entering production ramp.
