Nuclear/power names rip on Google and Amazon data-center deals; storage drives sink on Toshiba supply threat — Two clean, news-driven clusters this morning: utility/nuclear names (CEG, VST, TLN) are extending gains on fresh data-center power demand deals and policy tailwinds, while hard-drive makers (STX, WDC) are down hard on a competitor capacity-expansion scare. MRVL and ALAB are also firm into Marvell's Investor Day.

Candidates worth a look

7 names flagged from the watchlist.

IDEA CEG
Price
$301.00
That day
+12.5%

Google signed a 20-year deal adding 890MW of nuclear capacity to the PJM grid, just days after Amazon signed its own 20-year deal with Constellation -- biggest, cleanest mover on the whole list.

IDEA VST
Price
$156.62
That day
+8.1%

Reports of a roughly $4B federal loan package to fund capacity upgrades at three Vistra nuclear plants; riding the same data-center power demand wave as CEG.

IDEA TLN
Price
$356.74
That day
+7.5%

Extending gains alongside CEG/VST on the same nuclear power demand and policy tailwind -- genuine group move, worth watching if it holds into the close.

IDEA MRVL
Price
$298.26
That day
+10.0%

Running into today's Investor Day with AI data-center revenue as the focus; already up ~221% YTD so expectations are high -- a strong reaction either way is plausible.

IDEA ALAB
Price
$394.15
That day
+8.8%

Already a holding (8.24 sh at 303.25 avg cost, nicely green). Moving in sympathy with MRVL's AI-infra chip rally into Marvell's Investor Day -- no standalone ALAB headline found, so treat as a sector sympathy move.

IDEA STX
Price
$833.97
That day
-6.0%

Toshiba reportedly plans to double HDD output by FY27 to chase AI-datacenter storage demand, threatening the tight supply/demand picture that drove STX's 200%+ YTD run.

IDEA WDC
Price
$418.31
That day
-5.3%

Same Toshiba capacity-expansion overhang hitting STX; some desks already calling the initial selloff overdone, so watch for a relief bounce.

What this is (and isn't)

A second, independent lens on the same watchlist.

Every weekday morning, about 15 minutes after the market opens, a separate job re-reads the same maintained watchlist used by the overnight trading bot — but this time against live intraday action instead of yesterday's close. It's looking for setups that only become visible once the market is actually trading: a gap that's holding, a name reversing off the open, a sector moving together.

Timing

9:30 AM ET
The market opens. The overnight trading decisions (see the Morning Note) were already booked hours earlier at yesterday's close.
~9:45 AM ET
This job fires, pulls live intraday quotes for the full watchlist, and this page updates with whatever it found — or didn't.
~1:00 PM ET
A third job takes an afternoon-session read — index structure, breadth, sector leadership — on the Midday Report page.
