Biggest stock movers Friday: TSLA, AEHR, and more

Stock futures edged slightly lower in Friday’s premarket trading as investors eagerly awaited a series of major bank earnings reports set to be released today.

Here are some of Friday’s biggest stock movers:

Biggest stock gainers

• Aehr Test Systems (AEHR) shares surged more than 11% after the company reported upbeat FQ1 results. Despite the revenue falling approximately 37% Y/Y, Aehr Test Systems’ CEO, Gayn Erickson, expressed optimism about the company’s future, highlighting strong demand for their silicon carbide wafer level burn-in test systems, especially in the growing electric vehicle market. Erickson expects material bookings from expanding markets like AI processors, GaN semiconductors, and data storage devices, forecasting significant contributions to revenue. He also mentioned the successful integration of Incal Technology, boosting their capabilities in AI accelerators and data centers. With these growth drivers, Erickson reaffirmed the company’s FY2025 financial guidance for total revenue of at least $70M and net profit before taxes of at least 10% of revenue.
• Celsius Holdings (CELH) shares rose nearly 3% after Stifel highlighted positive takeaways from the National Association of Convenience Stores trade show. Analyst Mark Astrachan noted a more optimistic tone from brand owners and retailers regarding the potential for stronger convenience store category sales in 2025, a key channel accounting for 62% of energy drink sales. Looking ahead to Q4, Astrachan acknowledged potential weather-related impacts in the southeast U.S. but anticipates improving sales trends, driven by innovation, favorable comparisons, and pricing. He also expects Celsius Holdings to follow rival Monster Beverage (MNST) in raising prices by mid-single digits.

Biggest stock losers

• Tesla (TSLA) shares fell as much as 6% after CEO Elon Musk unveiled the highly anticipated ‘Cybercab’ robotaxi. Although Musk announced that the two-seater, driverless vehicle could enter production before 2027 with a price tag below $30,000, analysts criticized the presentation for its lack of clarity on the technology behind it. Musk, who made a grand entrance at the Los Angeles event in a Cybercab, emphasized that the regulatory challenges would need to be addressed before the service became operational.
