SanDisk finished Monday as the clear standout on a 110-stock board, rising 8.06% to close at $1,773.38, pulling hardware names into the spotlight as the session's dominant theme.

Coherent added 7.91% as the second-best performer, with Fabrinet, DigitalOcean and Futu Holdings also higher, reinforcing the strength in hardware-oriented names.

On the other side of the ledger, Clover Health fell 7.72% as the session's worst performer, joined by Trade Desk, SoundHound AI, Opendoor Technologies and Lemonade in a small-cap growth cohort that lagged.

Hardware led and small-cap growth lagged, a divergence that investors tracking either segment will want to keep an eye on heading into the next session.

A single $44 million bet on Micron calls expiring October 2 is the tell: someone is positioning for a violent upside move in memory and semis within two weeks.

"Someone" just bought a boatload of short data (October2) calls Intel 115 $3.8 m; Marvell 250sm $3.8 million; Sandisk 1600s $41 million, Micron $1000s $44 million. If i didn't know any better I would say Leopold is back!!!

Two years into Eric Bleeker's AI Portfolio pick, Coherent has turned $10,000 into roughly $35,080, and it survived a 30% drawdown in spring 2025 to get there. Anyone who sold during that slump missed the optical transceiver demand wave that followed.
