On June 4, Aehr Test Systems fell 8.23% in regular trading, trading at $110.55/share, with trading volume of $21.94 million.

On the news front, the semiconductor equipment sector is under broad-based selling pressure today, with major peers declining in tandem: Lam Research down 3.77%, Applied Materials down 3.36%, KLA-Tencor down 2.79%, Teradyne down 2.77%, and ASML down 1.87%. The sector-wide weakness has significantly weighed on individual stocks.

The stock had previously rallied sharply from its May 30 low near $91.91 to above $115, driven by a $41 million AI chip testing order catalyst. With substantial short-term accumulated gains, profit-taking has intensified amid the broader sector pullback. The stock's small-cap, high-volatility characteristics have amplified the magnitude of the decline relative to larger peers in the industry.
