AEHR TEST SYS

Nearly the entire institutional register of Aehr Test Systems (AEHR) is new: six of its 10 reporting holders arrived in Q2 2026, in a base worth just $2.9 million in total reported value. Y-Intercept (Hong Kong) Ltd is the largest holder by a wide margin at $1.2 million, or 41.3% of all institutional value, followed by B. Riley Wealth Advisors (16.3%) and Winthrop Partners (9.6%) — both also new positions. Combined, the six new entrants (Y-Intercept, B. Riley, Winthrop Partners, Brookstone Capital Management, Wealth Enhancement Advisory Services, and TEMA ETFs) account for roughly 87% of all institutional value in the stock, meaning almost the entire visible institutional ownership base appeared in a single quarter. Among the four pre-existing holders, CoreCap Advisors was the standout buyer, more than tripling its stake (+241.8% in shares, a real $85,013 addition), while GAMMA Investing and Versant Capital Management both trimmed modestly.
