Ultra Clean Holdings Inc

Ultra Clean Holdings surged on strong quarterly results and a sharp inflection in the outlook for semiconductor capital spending, according to Rewey Asset Management's second-quarter 2026 investor letter. The stock delivered a 127.81% return during the quarter, making it the top performer in the RAM Smid Composite, which gained 20.06% overall. Rewey noted that memory chips are now in short supply as artificial intelligence becomes a massive consumer of memory, and while the firm believes the upcycle is still in its early stages, it has trimmed its position into strength. Ultra Clean Holdings closed at $101.46 per share on July 22, 2026, with a one-month return of negative 17.80% and a 52-week gain of 319.14%, giving it a market capitalization of $4.55 billion.
