Aehr Test's stock surged 11.89% during intraday trading on Tuesday, marking a significant upward movement for the semiconductor testing equipment company.

The rally was driven by multiple converging factors. The company's previously secured $41 million AI chip testing order continues to provide strong fundamental support for the stock. At the sector level, the semiconductor equipment industry posted broad-based gains, creating a favorable environment for individual stock rallies.

Additionally, the stock had previously pulled back sharply from highs due to profit-taking and director share sales. With selling pressure now fully absorbed, ongoing oversold recovery momentum further contributed to the upward price action.
