Aehr Test's stock experienced a significant intraday decline of 11.89% during Monday's trading session, marking a sharp correction for the semiconductor equipment company.

The steep drop follows a sustained multi-day rally that had pushed the stock above its prior 52-week high, leading to substantial profit-taking pressure. Additionally, investor sentiment has been negatively impacted by the company's earlier $60 million common stock public offering, which raised concerns about equity dilution.

Further undermining confidence was a recent sale of 6,819 shares by a company director. The decline was amplified by broad weakness across the semiconductor equipment sector, with peers like Applied Materials, ASML Holding, and Lam Research also trading lower during the session.
