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.
Latest Activity
Chips and hardware took the top five slots at Thursday's close, led by ON Semiconductor's 5.52% gain, while every big decliner but one was a cybersecurity name. Zscaler's 9.88% drop to $193.43 was the worst in the group.
Fabrinet closed down 20% at $477.37, the deepest single-day loss in a 110-name priority list, with optical peers Applied Optoelectronics and Coherent also off double digits. Duolingo led all gainers at 8.3%.
AI optical demand pushed Fabrinet's quarterly revenue up 45% year over year to a record, its fifth straight quarter beating expectations. Guidance for the September quarter calls for $1.375 billion to $1.425 billion in revenue and non-GAAP EPS of $4.10 to $4.25, so the acceleration is not slowing yet.
Nearly 16 points separated the best and worst names in a 110-stock board at Monday's close, with SanDisk up 8% at $1,773 and Clover Health down almost 8%. Hardware led, small-cap growth lagged.
Fabrinet reports after the close at 4:15 PM ET, and as the contract manufacturer behind much of the industry's 800G optics, its commentary sets the tone for Lumentum, Coherent and AAOI. The $20.4 billion market cap leaves little room for a soft AI demand read.
Home Depot reports Tuesday before the open, the cleanest read yet on whether the housing-tied consumer is still spending. It anchors a 103-company week that also puts Baidu, Klarna and optical supplier Fabrinet on the tape.
