On May 22, Aehr Test Systems rose 8.31% in regular trading, trading at $89.35/share, with trading volume of $96.91 million.

The stock rebounded sharply after experiencing significant declines from its recent highs. The prior selloff was driven by profit-taking following a sustained multi-day rally, a director's reduction of 6,819 shares, and broad weakness across the semiconductor equipment sector. With selling pressure fully exhausted, oversold recovery demand pushed the stock higher from depressed levels.

On the fundamental side, the company's $41 million AI chip testing order continues to provide underlying support for the stock price. At the sector level, the semiconductor equipment industry strengthened broadly, with ASML Holding up 2.47%, Lam Research up 2.92%, KLA-Tencor up 1.54%, and Applied Materials up 0.28%, creating a favorable environment for the individual stock's rebound.
