On June 15, Astera Labs rose 5.88% in pre-market trading, trading at $387.88/share, with turnover of $1.3308 million.

On the news front, Nasdaq previously announced its quarterly rebalancing results, confirming Astera Labs will be added to the Nasdaq 100 Index alongside CoreWeave, NEBIUS, Rocket Lab, and Teradyne, with the adjustment set to take effect before the open on June 22. Index inclusion typically triggers mandatory allocation demand from passive funds, sustaining capital inflows ahead of the effective date. The Nasdaq 100 Index is tracked by over 200 investment products globally with assets under management exceeding $800 billion, amplifying the passive rebalancing effect.

In addition, the broader semiconductor sector rallied collectively, with Micron Technology up 6.97%, Marvell Technology up 5.26%, Advanced Micro Devices up 4.58%, Intel up 3.24%, and NVIDIA up 2.50%, providing further momentum through sector-wide linkage. The combination of index-driven capital flows and sector strength supported the continued upward move following the company's recent Taiwan business expansion and cloud-scale interoperability lab initiatives.
