On the news front, the company's previously secured $41 million AI chip testing mega-order continues to provide fundamental support for the stock. Management recently disclosed that a top-tier AI chip customer's benchmark testing, which lasted over six months, has been successfully completed with positive client feedback. Expectations for subsequent large-scale orders have strengthened, with the CEO indicating he will provide further details at the July 14 earnings call.

Within the Semiconductor Equipment sector, the broader group traded higher in the session. Among peers, ASML Holding up 3.94%, Applied Materials up 3.14%, Lam Research up 2.96%, KLA-Tencor up 2.59%, and Teradyne up 1.91%, reflecting sector-wide tailwinds that further amplified the stock's rebound given its small-cap, high-volatility characteristics.
