IDEXX Laboratories closed up 21.88%, the single largest move in a 383-name universe. Lumentum and Marvell sat at the other end of the session.

Tempus AI's Q3 earnings beat added roughly $1.5 billion of market value in one session. Whether the move holds through the close is the question for anyone still deciding on AI diagnostics.
Q3 was another record quarter, as we delivered $411.5 million of revenue, led by accelerating unit growth of 32% in our oncology business and increasing momentum of 33% revenue growth in Data & Applications.
The selling came first: a Form 4 shows Lefkofsky unloading shares on October 29, five days before he stepped up to call the quarter a record. Insider sales ahead of good news are common at founder-led companies, but anyone owning this one should note the CEO was trimming into the strength he just described.
Q3 was another record quarter, as we delivered $411.5 million of revenue, led by accelerating unit growth of 32% in our oncology business and increasing momentum of 33% revenue growth in Data & Applications.
Lefkofsky sold shares on September 24, five and a half weeks before stepping up to call the quarter a record, so the Form 4 came while he already had a line of sight on results. The words and the trade point in opposite directions, and insider timing is now part of the story for anyone buying the growth narrative at a $13.4 billion market cap.
Tempus AI turned its first adjusted profit, exceeding expectations that called for a loss, and raised full-year revenue guidance to roughly $1.6 billion.
1,301 companies report next week, and Monday alone front-loads the read on consumer, travel and chips before the open: Estée Lauder, Marriott, Fox, Check Point and Tower Semiconductor. With misses getting punished harder than usual this season, positioning ahead of Monday morning matters.

A 15.3% slide to $71.98 wipes roughly $2 billion off a $12.6 billion AI diagnostics name in a single session. Moves this big reset the whole trading range, so watch where it opens next.
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.
A 12.7% intraday slide to $74.22 strips roughly an eighth off a $13 billion market cap in a single session. Whether the $85 open gets reclaimed is the level to keep an eye on.
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.
