    JUSTIFIEDCONFIDENCE5/5

    Ultra Clean Holdings rose 16.2% on the day and accelerated another 5.54% in five minutes after reporting a substantial quarterly earnings and sales beat. The 22.3% EPS beat, 4.25% revenue beat, and 310.7% year-over-year EPS growth provide a concrete catalyst broadly consistent with a sharp repricing.

    WHYA 16.2% move, with a late 5.54% burst, is large but proportionate to a 22.3% EPS beat and 310.7% year-over-year EPS growth.

UCTT opened at $48.65, dipped to $46.91 shortly after the open, and then climbed through the session to a $51.98 high before ending regular trading at $51.48, up 10.2% from the previous close. TapeRank found no halts, and its read tied the late acceleration to the company’s quarterly results: an SEC 8-K reported operating results, while Benzinga said adjusted EPS of $1.15 and sales of $759 million beat estimates of $0.94 and $728.066 million. After the close, the stock reached $54.00 and then $57.07, its largest recorded move at 22.2% on the day.
