Astera (ALAB) Surges 1.73% on AI Infrastructure Momentum as $1.24 Billion Volume Ranks 66th in Market Activity

On September 5, 2025, Astera (ALAB) traded at a 1.73% gain, with a trading volume of $1.24 billion, ranking 66th in the market. The stock has shown resilience following a 29% surge in early August, driven by strong earnings surprises and increased demand.

Astera Labs, a fabless semiconductor firm, is emerging as a key player in AI infrastructure. Its technology enables "rack-scale AI" by connecting GPUs, CPUs, and memory across multiple servers, addressing scalability challenges in data centers. Analysts highlight the company’s role in reducing bottlenecks as AI workloads intensify, with major tech firms projected to spend $400 billion on AI CAPEX in 2025.

Financially, Astera has outperformed expectations, surpassing Zacks Consensus EPS estimates for four consecutive quarters by an average of 32.2%. Wall Street analysts anticipate a 88.10% EPS growth in 2025 and 24.14% in 2026, driven by sustained demand for its connectivity solutions. The stock’s recent performance aligns with its fundamentals, as volume surged 220% during its August rally.

To run an accurate back-test, parameters such as universe scope, ranking logic, and portfolio weighting must be confirmed. For instance, the strategy could involve selecting the top 500 U.S.-listed stocks by daily trading volume, re-ranking daily, and employing equal weighting. Transaction assumptions, including 1-day holding periods, and benchmark comparisons (e.g., SPY) would further refine the test. Implementation details are critical to ensure alignment with the intended strategy.
