Aehr Test Systems' stock surged 16.2% to $14.94 per share this afternoon, reflecting market optimism about its growth prospects, particularly against the backdrop of strong demand in the AI infrastructure sector.
The surge is attributed to Vicor's unexpected second-quarter revenue guidance increase, which indicates rising demand for AI infrastructure and positively impacts Aehr Test Systems. Additionally, Aehr secured a $41 million order from its lead hyperscaler customer, pushing its total orders for the second half of fiscal 2026 to over $92 million, significantly exceeding its previous guidance of $60 million to $80 million.
Although Aehr is a couple of years away from profitability, the ongoing growth in orders will bolster investor confidence, and if Vicor's positive signals continue, Aehr may receive more orders in the future, further solidifying its position in the AI data center market.

US Stocks Plunge as Tech Sector Weighs Down Market
- Market Weakness: On Wednesday, the S&P 500 Index fell by 1.21%, the Dow Jones Industrial Average dropped by 0.98%, and the Nasdaq 100 Index declined by 0.99%, reflecting market concerns over potential interest rate hikes by the Fed, particularly amid weak performance in technology stocks.
- Economic Data Support: Despite the market downturn, US May retail sales rose by 0.9% month-over-month, surpassing expectations of 0.6%, indicating resilient consumer demand, while pending home sales increased by 3.8% month-over-month, marking the largest gain in 20 months, potentially providing some support to the market.
- Fed Policy Outlook: The Fed maintained interest rates at its meeting on Wednesday but indicated through its dot plot that at least one more 25 basis point hike is expected this year, with the 2026 year-end federal funds rate projection raised to 3.75%, reflecting a cautious outlook on future economic conditions.
- International Market Response: While US stocks declined, overseas markets performed strongly, with the Euro Stoxx 50 reaching a new record high and closing up 0.68%, demonstrating global investor confidence in economic recovery, which may contrast with the US market's performance.
