AI-infrastructure names extend their run; storage megacap STX cools off — Dell and Qualcomm are both pushing further into AI-datacenter-driven highs this morning, while Seagate pulls back after its huge 2026 run. Rest of the watchlist is quiet with no other setups standing out.

Candidates worth a look

3 names flagged from the watchlist.

IDEA DELL
Price
$559.06
That day
+4.7%

Extending its record-high breakout (RBC Outperform initiation, $95B AI server backlog, joins S&P 100 on 9/21) -- already a held position, up sharply from our 516.39 avg cost.

IDEA QCOM
Price
$188.40
That day
+4.6%

Continuing the momentum from its Amazon data-center partnership news -- stock has been on a multi-day surge (+6% intraday moves recently) on data-center ambitions, not just a one-day pop.

IDEA STX
Price
$779.26
That day
-3.3%

Pulling back after a ~209% YTD run on AI/cloud storage demand -- looks like valuation-driven profit-taking (analysts flagging it as overvalued) rather than a change in the underlying AI-storage thesis.

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.
