Qty # 60 · Last Price $853.20 · Value $51,192.00 · Total Cost $63,243.50

AI memory is still the toll booth, and Micron’s HBM pricing power matters more than one China-competition scare dragging the tape down 5.65%. At a 19% position drawdown, I’d hold the core, buy weakness only in pieces, and trim fast if the gross-margin story cracks.

Qty # 10 · Last Price $1,411.08 · Value $14,110.80 · Total Cost $22,775.00

Memory is getting sold as a group, and SNDK is no exception: profit-taking is fine, but a 38% drawdown says this trade has lost control until pricing and margins reassert. I would not chase a bounce; trim strength, buy weakness only in pieces, and make SanDisk earn back the right to be owned, booyah.

-11.90%

Qty # 50 · Last Price $560.93 · Value $28,046.50 · Total Cost $31,833.90

Semicap equipment is under pressure, and with no fresh headlines this is multiple compression, not a thesis break. I’d stay long but not add into the first downtick: margins, China exposure, and AI capex orders have to do the talking, so AMAT remains own it, don’t trade it.

-13.19%

Qty # 20 · Last Price $500.94 · Value $10,018.80 · Total Cost $11,541.60

This is a biotech headline, not an AMD headline, so it does not change the call: AMD is still a data-center GPU and server share story. With the position down 13%, I’d buy weakness in pieces, but margins, HBM, and CoWoS capacity have to carry the next leg.

Total Gain %
-37.73%

Qty # 30 · Last Price $206.73 · Value $6,201.90 · Total Cost $9,960.00

Power infrastructure is the sector call: AI data centers need firm power, and Bloom is selling a real grid-pinch answer. After this 14% hit and 38% drawdown, I would hold the core, buy weakness only in pieces, and demand backlog-to-margin proof.

GEV

Total Gain %
-4.87%

Qty # 25 · Last Price $1,036.22 · Value $25,905.50 · Total Cost $27,230.50

Power equipment and grid buildout remain the story, but with no fresh catalyst and the position down 4.87%, this is a discipline check, not a panic sell. I’d stay long only if margins and backlog conversion keep compounding; otherwise trim strength because at $1036.22 this name has no room for execution slippage.

INTC

-26.77%

Qty # 150 · Last Price $96.98 · Value $14,547.00 · Total Cost $19,863.49

Semis are selling first and thinking later: Micron's China fear is dragging Intel by association, while the Google Cloud/Gemini rollout is internal efficiency, not a margin-reset catalyst. At -26.77% in the position, I'd stop adding until Intel shows foundry demand, gross-margin recovery, and real AI PC/server share gains; for now this is a hold, not booyah.

-39.01%

Qty # 90 · Last Price $188.30 · Value $16,947.00 · Total Cost $27,788.00

Semis are getting hit on Micron’s China memory scare, but MRVL is not a commodity DRAM story; it is AI networking, custom silicon, optical, and margin recovery. Down 39% on the position, I stay long and buy weakness in pieces, with a hard line that data-center orders and margins must keep improving or the thesis is broken.

SPCX

-37.54%

Qty # 2 · Last Price $131.11 · Value $262.22 · Total Cost $419.81

SpaceX in the other-holdings bucket is broken here: down 37% with only all-time-low and IPO-price headlines, there is no margin story, no capex payback story, no fundamental defense. I’d trim the dead weight, keep only a tracking position, and make it earn back the right to buy weakness in pieces.

TSM

-$1,333.20
Total Gain %
-13.99%

Qty # 20 · Last Price $409.74 · Value $8,194.80 · Total Cost $9,528.00

Semis first: TSMC raising capex and revenue forecast says AI chip demand is still ripping, with advanced-node capacity and CoWoS as the choke points. Down 2.32% today and -13.99% on the position is pain, not thesis damage; I’d own it, don’t trade it, and buy weakness in pieces.

WDC

-40.94%

Qty # 20 · Last Price $466.81 · Value $9,336.20 · Total Cost $15,809.28

Storage is getting sold with semis after a crowded memory run, not because cloud HDD demand or AI data-center capacity suddenly cracked. With the position down 40.94%, this is not a hero-buy; hold the core and only add in small pieces when margins and pricing show up in earnings.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$500.94 -$28.20 (-5.33%)

This is a media headline, not a chip read, so it does nothing for the AMD setup; watch AI accelerator demand, HBM supply, CoWoS capacity, and hyperscaler capex. Down 5% without AMD-specific news, I’d buy weakness only if datacenter GPU momentum and margin leverage stay intact.

AVGO

BROADCOM INC COM

$374.45 -$19.83 (-5.03%)

Semis are getting hit, but AVGO is still the AI infrastructure tollbooth: custom silicon, networking, VMware cash flow, and the CoWoS/HBM supply chain matter more than one ugly red day. Watch whether this weakness is just sector volatility against Morningstar’s undervalued call; I like this name on disciplined pullbacks, not panic chasing.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$180.46 -$3.55 (-1.93%)

No fresh headlines, no edge: CBRS is drifting with the tape, not flashing a fresh buy signal. I’d wait for company-specific news on margins, demand, or capex before chasing; down 1.93% is noise until the fundamentals move.

GLW

CORNING INC COM

$158.39 -$16.02 (-9.19%)

Optical and AI infrastructure first: no fresh headline means this is a tape reset, not a confirmed thesis break. Watch it, don’t chase it; I want July 28 earnings to prove data-center glass demand, margins, and capex customer spend are still holding before I like this name here.

GOOGL

ALPHABET INC CAP STK CL A

$354.46 -$16.46 (-4.44%)

AI is a shipping-cadence market, and a Gemini 3.5 Pro delay is a real narrative hit because Google has to prove TPU capex and model quality can translate into cloud share. Watch the next Cloud growth print and AI rollout pace; margins holding makes this a buy-the-fear setup, but execution has to show up.

LITE

LUMENTUM HLDGS INC COM

$706.23 -$45.77 (-6.09%)

No fresh headline means this is sector tape, not a thesis break: optical got too hot on AI capex and LITE is paying for it today. Watch datacenter orders, telecom inventory cleanup, and gross margin leverage; if those hold, I like this name on weakness, not on a chase.

LRCX

LAM RESEARCH CORP COM NEW

$320.96 -$14.47 (-4.31%)

Semicap is getting hit, but no fresh headline means this is sector multiple compression, not a Lam-specific crack. Watch memory capex, HBM tool demand, China revenue exposure, and gross margins; if those hold, I like this name on weakness.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$134.44 $0.68 (0.51%)

PLTR has no company-specific catalyst in this tape, so the setup is still enterprise AI budgets and government deal flow, not one random SPCX wobble. Watch margins, remaining performance obligations, and AIP customer expansion; above $134 this is a rich-multiple name where the trade is on only if growth keeps punching through.

PWR

QUANTA SVCS INC COM

$631.02 -$17.82 (-2.75%)

PWR is grid-power infrastructure, and a 2.75% down day with no fresh headlines does not change the electrification setup. Watch utility capex, data-center power demand, and backlog margins; I like this name on weakness, but only in pieces.

Q

QNITY ELECTRONICS INC COMMON STOCK

$135.47 -$4.76 (-3.39%)

No fresh headlines, so this 3.4% drop is tape pressure, not a thesis change. I’d wait for a real catalyst in margins, demand, or guidance before saying the trade is on.

RDDT

REDDIT INC CL A

$185.26 -$12.77 (-6.45%)

RDDT is a high-multiple internet ad name, so a 6.45% down day without fresh headlines says valuation compression, not thesis break. Watch ad load, user growth, AI licensing revenue, and margin leverage; I like the setup only on disciplined weakness, not a chase.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$272.45 -$20.95 (-7.14%)

This headline is not SIMO-specific; it is bank-litigation noise, not NAND controller demand, margins, or customer inventory. Watch the real setup: PC and handset restocking, NAND capex discipline, and whether this 7% hit creates a cleaner entry after guidance holds.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$409.74 -$9.74 (-2.32%)

Semis are cooling today, but TSM is still the toll road for AI capex: watch CoWoS capacity, advanced-node pricing, and whether Nvidia/Apple concentration keeps margins fat. Down 2.3% does not change the setup; I like this name on weakness, but the trigger is capacity commentary and gross margin, not a random fund-position headline.
