Penguin Solutions and Manpower Group have been highlighted as Zacks Bull and Bear of the Day

Penguin Solutions (PENG) took Zacks' Bull of the Day after Q4 earnings per share more than doubled and the company raised its fiscal 2027 guidance by 40%. The source ties the strength to AI infrastructure demand.

Manpower Group (MAN) landed the Bear of the Day label after a Q3 revenue miss and weak forward guidance. Analyst estimates are being cut as recovery momentum slows, a sign that Wall Street is marking down its outlook for the staffing firm rather than waiting for confirmation.

The same piece flags a separate risk for Chinese automakers. A China-EU hybrid vehicle import quota could affect BYDDY, XPEV, and NIO. The source frames this as a potential impact rather than a settled outcome, so the effect on each name remains unquantified.

Interpretation: the 40% guidance raise gives PENG a concrete earnings-revision tailwind, while MAN faces the opposite dynamic, with downward estimate cuts typically pressuring sentiment until a new baseline sets. The contrast between a doubling in EPS and a revenue miss with soft guidance makes this a clean divergence pairing between AI-linked demand and cyclical hiring exposure.
