Qty # 60 · Last Price $984.75 · Value $59,085.00 · Total Cost $63,243.50

Semis first: memory is still the AI bottleneck, and Tokyo putting billions behind Micron says HBM capacity matters more than today’s ugly tape. Stay long and buy weakness in pieces; own it, don’t trade it, unless margins crack from oversupply and capex outruns pricing.

Qty # 10 · Last Price $1,744.43 · Value $17,444.30 · Total Cost $22,775.00

Memory is getting bought again, and Sandisk belongs in the AI storage lane where capex is still king. I’d stay long, buy weakness in pieces, and demand margin proof before getting aggressive.

Qty # 50 · Last Price $592.79 · Value $29,639.50 · Total Cost $31,833.90

Semicap is still the AI plumbing trade, and AMAT lives where HBM, advanced packaging, foundry capex, and margin discipline matter. No fresh headline means no new catalyst, so I’d stay long but keep it as an “own it, don’t trade it” holding unless the capex cycle starts cracking.

Qty # 20 · Last Price $552.05 · Value $11,041.00 · Total Cost $11,541.60

Semis first: autos are becoming AI data centers on wheels, and AMD getting Turing onto its GPUs is a real demand signal outside the hyperscaler lane. I like the name here but this is not thesis-changing yet; stay long, buy weakness in pieces, and watch GPU supply, software attach, and margins.

-11.13%

Qty # 30 · Last Price $295.05 · Value $8,851.50 · Total Cost $9,960.00

Energy infrastructure first: Tokyo backing Micron’s chip buildout says AI capex still needs power, and BE sits right in the grid-power pinch point. At $295.05 with the position still down 11%, I’d stay long but only add on weakness if margins and backlog keep improving.

5.77%

Qty # 25 · Last Price $1,152.04 · Value $28,801.00 · Total Cost $27,230.50

GEV is a power scarcity story: grid buildout, gas turbine demand, services backlog, and pricing power keep the fundamentals in charge even with no fresh headlines. At $1152 after a +5.77% position gain, I’d stay long but stop chasing green candles, buy weakness in pieces, own it, don’t trade it.

Qty # 150 · Last Price $122.20 · Value $18,330.00 · Total Cost $19,863.49

Semis have the bid and Trump lit up the PC trade through Dell, but INTC is still a margin-and-capex story, not a victory lap. I’d keep it small, buy weakness in pieces only, and demand real foundry customer wins before calling the trade on.

Qty # 90 · Last Price $249.27 · Value $22,434.30 · Total Cost $27,788.00

Semis need fresh orders or margin leverage to work, and MRVL has no new HBM, optical, or custom silicon catalyst on the board today. At down 19%, I’d buy weakness only in pieces and demand proof that data-center revenue is accelerating.

-23.57%

Qty # 2 · Last Price $160.42 · Value $320.84 · Total Cost $419.81

Aerospace and satellite broadband are the sector read: Starlink launch cadence plus Nasdaq-100 inclusion creates forced ownership, while the chip-test payload is optional upside until it proves margin or capex leverage. Down 23.57% in the position, I would stay long and add only in pieces on weakness because the core story is scale, launch reuse, and distribution; own it, don't trade it.

Qty # 20 · Last Price $451.79 · Value $9,035.80 · Total Cost $9,528.00

Semis are under pressure on AI valuation fear, but Samsung’s blockbuster earnings and SK Hynix chasing U.S. AI investors say the demand curve is still alive and the bottlenecks are HBM, CoWoS, and leading-edge wafer capacity. For TSM, stay long and buy weakness in pieces; this is the toll road on AI capex, not a broken thesis, booyah.

Qty # 20 · Last Price $577.46 · Value $11,549.20 · Total Cost $15,809.28

Storage and memory are catching a bid with chips recovering, but WDC is not the cleanest AI supply-chain play unless HDD pricing and cloud capex keep tightening capacity. Down 26.95% in the position, I’m not chasing a flat tape at $577.46; buy weakness in pieces or keep the capital for higher-quality memory winners.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$552.05 $0.00 (0.00%)

This is an AI-infrastructure read, not an AMD-specific catalyst: industrial buyers are validating the cycle, and the real tells are hyperscaler capex, HBM supply, CoWoS allocation, and MI350 customer breadth. At $552.05 with no move today, the setup has not changed: I like the name on the watchlist, but the trade is on only when real customer wins or supply unlocks show up.

AVGO

BROADCOM INC COM

$373.90 $0.00 (0.00%)

AVGO is the AI infrastructure toll road: custom silicon, networking, optical, and VMware margins are the whole story. I like this name here, but in watchlist mode the tell is order visibility and CoWoS/HBM supply, not a flat one-day print.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$192.01 $0.00 (0.00%)

AI compute stays the sector, but no fresh headlines means no new catalyst and no reason to chase a flat tape. Watch margins, customer concentration, HBM/CoWoS access, and power constraints; if those improve, the trade is on.

GLW

CORNING INC COM

$194.80 $0.00 (0.00%)

Optical and specialty glass are the story here, with AI data-center demand and fiber capex needing to show up in margins, not just revenue talk. I like watching GLW for operating leverage, but without fresh headlines the trade is patience, not chase.

GOOGL

ALPHABET INC CAP STK CL A

$366.46 $0.00 (0.00%)

Big Tech capex cage fight, and GOOGL has the cash engine to stay in it, but the test is margins as Gemini, cloud, TPU, data centers, and power bills ramp. On watchlist, don’t chase a flat $366.46 tape; wait for cloud acceleration and ad share defense, then buy weakness in pieces.

LITE

LUMENTUM HLDGS INC COM

$731.25 $0.00 (0.00%)

Optical is still an AI infrastructure trade, but with no fresh headlines and a flat tape, LITE has to prove datacenter laser demand and margin expansion. Watch customer concentration, capacity, and hyperscaler capex; I like the setup only on real bookings strength, not dead-tape chasing.

NVDA

NVIDIA CORPORATION COM

$195.55 $0.00 (0.00%)

AI semis are still the sector to beat, but the market is now asking whether Nvidia’s valuation already prices in share loss instead of endless GPU dominance. For a watchlist name, I watch gross margin, HBM/CoWoS supply, and hyperscaler capex; if those stay firm, I like this name on weakness, booyah.

PWR

QUANTA SVCS INC COM

$674.04 $0.00 (0.00%)

Grid power is the sector, and PWR is still an AI infrastructure toll road as long as backlog, electric margins, and data-center capex hold up. No fresh headline means no chase here; watch weakness for a cleaner setup, booyah.

Q

QNITY ELECTRONICS INC COMMON STOCK

$146.68 $0.00 (0.00%)

No fresh headlines means no new fundamental catalyst, so Q needs margin leverage and cleaner demand to make the trade worth chasing. At $146.68 flat, I watch it, I do not force it; the setup only improves on real earnings power.

RDDT

REDDIT INC CL A

$200.86 $0.00 (0.00%)

The trade is on if Reddit can turn messy community intent into high-margin ad dollars without wrecking the product. At $200.86 flat on the day, watch B2B ad demand, brand-safety tools, and data licensing because margins decide whether this is a real platform story or just traffic with attitude.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$318.86 $0.00 (0.00%)

This headline is bank-litigation noise, not a SIMO catalyst, so keep the lens on semis and NAND controller demand. For a watchlist name, I want margin lift from mix and cleaner customer inventory before saying the trade is on.
