On June 9, Aehr Test Systems rose 8.3% in regular trading, trading at $106.06/share, with trading volume of $33.49 million. The rally was driven by the continued catalyst from the company's previously secured $41 million AI chip testing order and broad semiconductor equipment sector strength.

On the fundamental side, management recently disclosed that a top-tier AI chip customer's benchmark testing, which lasted over six months, has been successfully completed with positive feedback. CEO indicated that more details will be shared at the July 14 earnings call, strengthening expectations for subsequent large-scale orders. The stock had experienced a cumulative decline of over 16% on June 4-5 as the semiconductor equipment sector pulled back sharply, creating oversold conditions that fueled technical rebound momentum.

Within the Semiconductor Equipment sector, the industry rallied broadly today. Among peers, Lam Research rose 6.49%, KLA-Tencor rose 6.44%, Applied Materials rose 6.01%, AXT Inc rose 4.05%, and ASML rose 3.77%. The sector-wide recovery amplified the rebound in AEHR given its small-cap, high-beta characteristics.
