On July 9, Aehr Test Systems rose 8.34% in pre-market trading, trading at $76.7/share, with turnover of $2.93 million. The stock is staging an oversold recovery following a dramatic selloff that saw cumulative losses of nearly 20% between July 7 and July 8, which itself followed a 17.13% single-day plunge on July 2.

The rebound is primarily driven by a broad-based recovery across the semiconductor equipment sector. On the same day, Applied Materials rose 4.66%, Lam Research gained 4.46%, KLA-Tencor advanced 4.21%, Teradyne climbed 4.18%, and ASML Holding added 1.3%, reflecting systematic buying pressure returning to the sector after days of heavy selling.

On the fundamental side, the company previously secured a record $41 million AI chip testing order, with management noting that a top-tier AI chip customer completed over six months of benchmark testing successfully, strengthening expectations for follow-up large-scale orders. Additionally, a silicon photonics burn-in system follow-up order was received in June. The company is scheduled to report earnings on July 14.
