Investing in the artificial intelligence theme has been nothing short of a wild ride in 2026, especially when it comes to stocks that are not household names. Few stocks provide a better example of this dynamic than the semiconductor testing equipment company Aehr Test Systems (NASDAQ: AEHR).
Throughout the year, Aehr has moved from a market capitalization of less than $700 million to well over $3 billion. This has resulted in a year-to-date (YTD) return that exceeds 400%, making Aehr easily one of the best-performing stocks of 2026.
