Why Is AEHR TEST SYS (AEHR) Stock Down Today?

AEHR Test Systems fell 5.68% to $75.68 in Tuesday's session amid a sharp intraday decline and a wave of insider selling. The stock opened with a modest 0.9% gap up but quickly reversed course, hitting a session low of $74.83 before settling near $75.75. The move follows a 12-month surge of 695% and a recent pullback of nearly 19% over eight trading sessions.

What Happened

The stock's decline was driven by a combination of weak fundamentals and a notable sell-off by insiders. Aehr Test Systems reported a trailing twelve-month revenue decline of 15.2%, an unprofitable EPS of -$0.23, and a net margin of -14.3%. These figures highlight the company's ongoing financial challenges despite its recent rally. On August 14, 2026, several insiders including EVP of Sales and Marketing Vernon Rogers and directors Rhea J. Posedel and Howard T. Slayen sold shares. These transactions occurred against a backdrop of $18.9 million in insider sales over the past 90 days, with no insider purchases recorded.

What The Data Shows

The stock opened at $81.00, but by 10:00 AM ET, it had fallen to $74.83, a level that marked a fresh 52-week low. The session's volume of 0.5 million shares was above the 3-month average by a factor of 0.2x, indicating increased selling pressure. Over the past 8 sessions, the stock has dropped from $96.43 to $77.74, a loss of 19.4%. The broader technology sector also saw downward momentum, as noted in multiple Benzinga reports highlighting pre-market declines in several tech stocks.
