Memory is the AI semis battleground: Micron is getting punished on cycle fear, capex anxiety, and doubts that HBM strength can keep margins expanding. At a 19% drawdown I would not puke it; buy weakness in pieces, because the HBM/data-center memory trade is still on.

Qty # 10 · Last Price $1,354.82 · Value $13,548.20 · Total Cost $22,775.00

Sector first: chip derisking is hitting everything, and SNDK at -40% in the position is not a buy-more moment just because AI storage is real. I’d keep a core, demand NAND margin proof and enterprise SSD pull-through, then buy weakness in pieces when the fundamentals turn; until then, own it small, don’t trade it.

Qty # 50 · Last Price $529.66 · Value $26,483.00 · Total Cost $31,833.90

Applied Materials is the essential backbone of the semiconductor supply chain and the CoWoS ramp remains a massive structural tailwind. You are down, but the margins are too strong to panic so you have to own it, don't trade it.

-14.09%

Qty # 20 · Last Price $495.76 · Value $9,915.20 · Total Cost $11,541.60

Semis first: this AMD headline set is consumer CPU noise, while the real stock driver is MI accelerator demand, HBM supply, CoWoS access, and data-center margins. Do not chase the red tape; hold it as a show-me position and buy weakness only in pieces when AI server traction proves the trade is on.

-35.25%

Qty # 30 · Last Price $214.96 · Value $6,448.80 · Total Cost $9,960.00

Power infrastructure is the story: emissions pressure at mega data centers makes clean, firm onsite generation more valuable, and BE is in the right lane. The stock is ripping but the position is still down hard, so I’d stay long, buy weakness in pieces, and demand proof in backlog conversion, gross margin, and repeat data-center customers.

-2.88%

Qty # 25 · Last Price $1,057.84 · Value $26,446.00 · Total Cost $27,230.50

GEV is a pure play on the massive structural need for grid power and electrification infrastructure. Own this name for the long haul because the supply-chain bottleneck in transformers remains the ultimate bull case.

-28.23%

Qty # 150 · Last Price $95.04 · Value $14,256.00 · Total Cost $19,863.49

Semis are in the penalty box: the AI multiple got too hot, fund outflows are forcing de-risking, and INTC still needs proof that margins and foundry capex can earn their keep. I would not chase a bounce; keep it sized as other holdings, buy only real weakness in pieces, and demand execution before calling this anything but a turnaround position.

-38.89%

Qty # 90 · Last Price $188.68 · Value $16,981.20 · Total Cost $27,788.00

Marvell is the premier play on custom silicon and optical interconnects that you need to hold through this data center infrastructure supercycle. Ignore the short-term noise and add to your position on any weakness because the margin expansion story remains intact.

Qty # 2 · Last Price $123.99 · Value $247.98 · Total Cost $419.81

Space is high-beta growth, and today the trade is off: the Starship scrub handed shorts a clean catalyst while the AI-led selloff pulled every long-duration story lower. Own it, don’t trade it; I’d stop averaging down until launch cadence gets clean, because reuse economics and launch reliability decide this name, not the IPO-price line.

Qty # 20 · Last Price $398.37 · Value $7,967.40 · Total Cost $9,528.00

Semis are still the center of the AI capex trade, and TSM just gave you the receipts: Q2 beat, leading-edge demand, TD Cowen target to $440. The stock is ugly today and the position is underwater, but CoWoS capacity, pricing power, and margin scale say stay long and buy weakness in pieces, own it don’t trade it.

WDC

Qty # 20 · Last Price $477.22 · Value $9,544.40 · Total Cost $15,809.28

Storage is catching a bid, but with chips weakening and WDC still down hard, this is a stay-small name, not a victory lap. I’d trim strength and keep only a tracking position, because the better fundamentals sit in AI capex winners with tighter supply chains and expanding margins.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$495.76 -$5.18 (-1.03%)

Semis drive this story, not Netflix ad chatter, so this headline does not move AMD. Watch data-center GPU share, HBM and CoWoS supply, and hyperscaler capex breadth; I like the setup on weakness, but Nvidia remains the benchmark.

AVGO

BROADCOM INC COM

$370.82 -$3.62 (-0.97%)

Semis first: AVGO is still a premier AI infrastructure tollbooth, but slower hyperscaler spending growth makes the setup about order durability, not the one-day dip. Watch custom silicon bookings, networking margins, and customer concentration; I like the name on weakness, but the trade is on only if capex budgets hold.

GLW

CORNING INC COM

$154.61 -$3.78 (-2.39%)

No fresh headlines, so this is sector-first: Corning lives or dies on AI optical demand, display glass pricing, and margin leverage without runaway capex. The 2.39% dip is noise; watch order commentary and cash-flow guidance, because I like this name on weakness if optical keeps carrying the story.

GOOGL

ALPHABET INC CAP STK CL A

$346.77 -$7.69 (-2.17%)

AI is the sector tape, and a reported Gemini delay hurts because Alphabet is being valued on execution speed, not just ad dominance. Watch whether this is a timing hiccup or a real share-loss risk in enterprise AI; if search margins stay clean and capex discipline holds, this pullback does not break the setup.

LITE

LUMENTUM HLDGS INC COM

$732.82 $26.59 (3.77%)

Optical is the AI plumbing trade, and LITE moving 3.77% on no fresh news says the tape still wants datacenter bandwidth names. Watch orders, margins, and supply tightness in high-speed transceivers; I like the setup, but the buy is on weakness, not after a quiet rip.

Q

QNITY ELECTRONICS INC COMMON STOCK

$136.35 $0.88 (0.65%)

No fresh headlines, so the +0.65% move is just tape, not a new setup. Watch the next earnings print for margin durability and demand signals; without that, I wait for a cleaner pitch.

RDDT

REDDIT INC CL A

$181.18 -$4.08 (-2.20%)

RDDT is an internet ad platform with a scarce AI-data asset, and a down day with no fresh headlines does not break the story. Watch ad pricing, daily users, data-licensing revenue, and margin flow-through; I like this name on pullbacks, not on air pockets.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$264.32 -$8.12 (-2.98%)

Semis are soft today, and with no fresh headline, SIMO’s move is just tape pressure until NAND/controller demand or customer inventory data says otherwise. Watch margins and China exposure; I like the setup only on weakness tied to sector panic, not company-specific deterioration.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$398.37 -$11.37 (-2.77%)

Foundry cycle is intact: TSM beat Q2 and guided on leading-edge demand, so the tells are AI wafer starts, CoWoS/HBM packaging capacity, and gross margins against capex and power costs. Down 2.77% on a beat is profit-taking, not a thesis break; I like this name on weakness, but customer concentration and Taiwan risk stay front and center.
