Qty # 25 · Last Price $1,000.26 · Value $25,006.50 · Total Cost $23,635.60

MU’s real engine is AI-driven HBM demand and disciplined memory supply, not a private-equity “breakout” call. Stay long and buy weakness in pieces—own it, don’t trade it.

Qty # 20 · Last Price $225.73 · Value $4,514.60 · Total Cost $4,537.18

NVDA’s 2% dip is noise while AI accelerator demand, HBM supply, and CoWoS capacity keep the earnings machine humming. Buy weakness in pieces and own it, don’t trade it—this position is barely underwater and the AI semiconductor trade is still on.

11.01%

Qty # 30 · Last Price $368.16 · Value $11,044.80 · Total Cost $9,949.00

TSLA’s 3.98% pop is sentiment-driven, while EV margins and Cybercab execution remain the fundamental pressure points. Stay long after an 11.01% gain, but don’t chase this move—own it, don’t trade it.

Watchlist

AVGO

BROADCOM INC COM

$368.56 $10.66 (2.98%)

AI infrastructure is still the trade, but Broadcom’s earnings must prove that custom silicon and networking growth can outrun heavy AI capex and supply-chain pinch points. A 3% pop doesn’t change the setup—I like this name on post-earnings weakness, not ahead of the implied-move coin flip.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$199.77 -$10.28 (-4.89%)

AI infrastructure is still the hottest trade, but CBRS giving back 4.9% after a Europe-driven surge says expectations are running ahead of confirmed economics. Watch the European deal’s revenue, margins, and customer concentration before chasing—buy only after the story proves it can scale.

GOOGL

ALPHABET INC CAP STK CL A

$338.36 -$0.10 (-0.03%)

The flat tape changes nothing; watch Google Cloud growth and whether AI capex converts into durable margin expansion. I like this name on weakness, but at $338 the trade needs earnings power, not hype.

IRDM

IRIDIUM COMMUNICATIONS INC COM

$47.80 $0.59 (1.25%)

Satellite communications remain a cash-flow story, and this tiny $95,342 officer sale is noise—not a change in the setup. Watch subscriber growth, service margins, and constellation-replacement capex; I like IRDM here, but buy weakness in pieces.

LITE

LUMENTUM HLDGS INC COM

$978.53 $97.28 (11.04%)

The AI optics trade is on, but an 11% surge after more than doubling this year makes fresh chasing reckless. Watch cloud capex, optical-component margins, and customer concentration—buy weakness in pieces if the fundamentals keep accelerating.

LRCX

LAM RESEARCH CORP COM NEW

$320.42 $12.77 (4.15%)

The semiconductor-equipment trade is on, but after a 4% pop on target hikes, watch memory capex and advanced-packaging demand before chasing LRCX. I like this name on weakness because etch intensity rises with more complex chips.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$170.30 -$4.03 (-2.31%)

PLTR’s growth and profitability story remains elite, but at $170 the valuation demands flawless execution and accelerating commercial adoption. Today’s dip does not change the setup—watch margins and customer concentration, and wait for a sharper reset before the trade is on.

PWR

QUANTA SVCS INC COM

$639.05 $14.64 (2.34%)

Grid infrastructure is the trade as power demand and transmission bottlenecks drive multiyear spending, and Quanta’s venture adds another growth lever. At $639 after a strong run, watch backlog growth and margins—I like the business, but buy weakness instead of chasing.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$272.02 $15.81 (6.17%)

The NAND-controller trade is on, but a 6% pop on a generic buy-now headline does not change the setup. Watch NAND pricing, client-SSD demand, customer concentration, and gross margins before chasing SIMO here.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$439.00 $10.09 (2.35%)

AI foundry demand keeps the trade on, but watch HBM supply, CoWoS capacity, and capex discipline for proof that margins can keep climbing. The 2.35% move does not change the setup—I like TSM here, but buy weakness in pieces.
