This Data Center Play Wavers In A Base After Gaining 50% In Three Weeks

Astera Labs (ALAB) is building a technical base and showing leadership within the hot data-center/AI group, which supports further upside for chip-infrastructure names. The stock reclaimed its 200-day moving average, sits above its 50-day which is beginning to turn up, and is completing the right side of a cup base with a 192.86 buy point (possible handle entry at 175.60). Fundamental momentum accompanies the chart setup: Q4 EPS rose 57% to $0.58 and sales jumped 92% to $270.6M; management guided Q1 to $0.53–$0.54 EPS on $286M–$297M revenue and reports May 5. Institutional accumulation and a top-tier IBD Composite Rating (96) and rising RS reinforce bullish bias, though the 21-day ATR of 7.8% signals above-average volatility. Overall, the piece is constructive for Astera and supportive for related AI/data-center stocks, while advising caution around potential pullbacks/handle formation.
