Qty # 60 · Last Price $848.95 · Value $50,937.00 · Total Cost $63,243.50

Memory is under pressure: SK hynix sentiment is ugly and CXMT's IPO demand getting hit tells you investors are punishing the whole DRAM/NAND complex, not just MU. Stay long, don't average blindly; buy weakness in pieces only where HBM pricing, CoWoS-linked demand, and capex discipline stay intact, because AI memory is a cycle you own when supply stays tight.

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

Storage is the AI buildout piece here, but with no fresh headlines this is a margin-and-cycle call, not a victory lap. Down 40.51% on the position, I would not press it at $1354.82; buy weakness in pieces only if NAND pricing and capex discipline keep improving.

-16.81%

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

Semicap equipment is a margins-and-capex story, and AMAT needs foundry, memory, and advanced packaging spend to keep the HBM and CoWoS buildout moving. No fresh tape means no chase; with the position down 16.81%, I’d keep a core and only add weakness in pieces.

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

Semis first: with no fresh headline, AMD is still a data-center AI execution story, and it needs MI-chip revenue, clean supply, and better margins to matter. At down 14% in the position, I’d hold the core and add only on real weakness; the trade is on when data-center margin proves the story.

-35.25%

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

Clean power is the sector, and these headlines are noise, not signal for Bloom; the real story is fuel-cell demand tied to AI data-center power, margins, and project economics. At a -35% position loss, I’d keep it on a tight leash: buy weakness only in small pieces after real bookings and margin traction show up, because hope is not a thesis.

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

Sector first: power equipment beats chip angst here, because Big Tech earnings reinforce the grid bottleneck, gas turbine backlog, and electrification capex GEV sells into. I like this name on weakness, but at $1,057.84 buy it in pieces and demand margin execution, not rotation noise.

-28.23%

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

Semis are getting tested after the rotation cracked, and Intel has to prove Thursday night that margins, foundry losses, and AI relevance are improving. With the position down 28%, I’d keep it on a short leash: no hero buying before the print, add only after concrete capex discipline, otherwise trim strength.

-38.89%

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

Semis are still the sector, but MRVL needs proof in custom AI silicon and optical before it gets re-rated; margins and hyperscaler concentration matter more than the flat tape. Down 39%, I would not panic-sell it with no bad news, but I would keep it sized as a show-me holding and add only on confirmed AI revenue acceleration.

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

Space and AI infrastructure first: SPCX is a broken tape, but Foxconn’s reported $52B GB300 cabinet order screams massive compute capex and real customer pull. No hero averaging down; keep it small, own only a starter, and buy weakness in pieces only when margins and delivery milestones show up.

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

Semis first: TSM is the AI foundry toll road, and these small institutional buy headlines are noise, not the catalyst. Stay long, add only on weakness, because CoWoS capacity, HBM pull-through, and margins matter more than one RIA filing.

-39.63%

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

Storage is the tell: reckless cyber actors make backup, recovery, and clean data custody more mission-critical, which gives WDC a real demand floor despite the ugly position loss. I would not chase a flat tape at $477.22; buy weakness in pieces, demand margin discipline, and trim the laggard if pricing rolls over.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$495.76 $0.00 (0.00%)

Semis are under fresh China AI pressure, and AMD has to prove its AI GPU roadmap can win real hyperscaler dollars while local models like Kimi K3 squeeze the narrative. Watch margins, HBM and CoWoS supply, and customer breadth; I like this name on weakness, not after the headline heat.

AVGO

BROADCOM INC COM

$370.82 $0.00 (0.00%)

AVGO is still a semis-plus-infrastructure name, so watch AI custom silicon, networking demand, VMware margins, and customer concentration more than a flat day at $370.82. I like this name on weakness if margins hold and AI capex stays hot; chase only if the next print proves the growth is accelerating.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$172.86 $0.00 (0.00%)

AI hardware is the sector call, but with no fresh headline, CBRS has to prove revenue quality, gross margin, and supply-chain execution around wafer-scale systems, power, and data-center deployment. I like it as a watchlist name on weakness; the setup changes when customers broaden beyond a few whale AI buyers and margins prove this is more than IPO heat.

GLW

CORNING INC COM

$154.61 $0.00 (0.00%)

No fresh tape, so GLW is a fundamentals watch: optical demand from data centers and telecom, display glass pricing, and margins have to do the talking. I’d wait for a catalyst or a pullback, because without news and a flat print, the trade is on only if AI optical orders and pricing power keep accelerating.

GOOGL

ALPHABET INC CAP STK CL A

$346.77 $0.00 (0.00%)

GOOGL is a mega-cap AI-advertising earnings story now, and the market wants proof that Search, YouTube, and Cloud can absorb AI capex without margin damage. For a watchlist name, I like buying only a real post-earnings reset; at $346.77 flat on the day, the trade is on only if revenue growth and cloud margins beat the capex scare.

IRDM

IRIDIUM COMMUNICATIONS INC COM

$46.68 $0.00 (0.00%)

Satellite connectivity and resilient navigation are the aerospace-defense lane, but this Q-CTRL headline is not an IRDM catalyst unless it pulls LEO comms into aviation redundancy budgets. Watch government, IoT, and aviation uptake; I like the theme, but the setup needs a real Iridium tie-in before the trade is on.

LITE

LUMENTUM HLDGS INC COM

$732.82 $0.00 (0.00%)

No fresh headlines means no new catalyst; for LITE the watch is optical demand tied to AI data centers, telecom digestion, margins, and whether supply tightens. I like the sector setup, but I’d buy weakness only when orders and guidance confirm the trade is on.

LRCX

LAM RESEARCH CORP COM NEW

$313.30 $0.00 (0.00%)

That World Cup ticketing headline is pure noise for LRCX; this is semicap equipment, and the read-through is memory capex, HBM pull-through, China controls, and gross margin leverage. Flat tape at $313 says wait for the next wafer-fab spending signal, because the trade is on only when Lam shows orders are accelerating.

NVDA

NVIDIA CORPORATION COM

$202.81 $0.00 (0.00%)

Semis are still the toll road, but this headline says the marginal AI dollar is hunting software and device monetization, not just more GPU capex. For NVDA watch hyperscaler capex, HBM and CoWoS supply, and gross margin durability; I like the name, but buy weakness in pieces, not flat tape.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$132.38 $0.00 (0.00%)

AI software is where the trade is on, but PLTR has to prove enterprise AI turns into durable spend, not token-rental theater, and Karp is pressing that exact pressure point. At $132 with no move today, watch AIP deal velocity, operating margins, and customer concentration; I like the setup only on weakness unless growth re-accelerates cleanly.

PWR

QUANTA SVCS INC COM

$628.53 $0.00 (0.00%)

PWR is the grid-power toll road: transmission, utility hardening, data-center load, and renewables interconnects keep the backlog story alive even with the stock parked at $628.53. Watch margins and labor capacity, because clean execution keeps this a buy-on-weakness watchlist name; chase only if backlog and guidance move higher.

Q

QNITY ELECTRONICS INC COMMON STOCK

$136.35 $0.00 (0.00%)

No fresh headlines means no new catalyst: watch whether the sector is rewarding margin durability, capex discipline, and clean demand. At $136.35, the setup has not changed; I wait for a real fundamental trigger before saying the trade is on.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$264.32 $0.00 (0.00%)

This is SiC wafer cleanup, not a direct SIMO catalyst; power semi supply is getting rationalized while controller names still need NAND demand to do the work. Watch customer orders, gross margin, and SSD controller share, because without those improving, the trade is not on.
