Tempus AI, Inc. Class A Common Stock

Nearly 29 points of spread separated the top and bottom of the board at Monday's close, with Ciena up 14.29% to $445.37 and Tempus AI down 14.21% to $71.68. Four of the five leaders sit in AI infrastructure names.

Both Petrobras lines closed double digits higher, the only names in a 383-stock board to do it. MercadoLibre and Tempus AI each added more than 9%, while the worst loser gave up under 5%, so the upside skew was lopsided.

Three names in our 383-stock board closed with double-digit gains, led by Accenture's 15.6% jump to $211.97, a move that size is rare for a mega-cap consultant. The downside was far tamer, with AMC's 8.2% slide the worst of it.

Tempus AI closed 14.46% higher, the biggest move in a 111-name priority list where four other gainers ran 9% or better. The downside was far tamer: DraftKings led decliners at 7.38%, and nothing else lost more than 6.4%.

Tempus AI closed the session up 10.5%, the only double-digit move among 111 tracked names. The downside was deeper and broader: Axon, Cava and Clover Health all gave up more than 9%.
