Qty # 60 · Last Price $904.28 · Value $54,256.80 · Total Cost $63,243.50

Memory is the battleground: China competition threatens commodity DRAM margins, but AI HBM demand keeps Micron in the right lane. With the position down 14%, I would buy weakness in pieces, ignore ETF-driven pops, and stay long unless gross margins crack from pricing pressure.

Qty # 10 · Last Price $1,615.00 · Value $16,150.00 · Total Cost $22,775.00

Memory is still the AI plumbing trade, but SNDK’s tape is being shoved around by leveraged-ETF tourists and profit-taking, not a change in storage demand. At a 29% position drawdown, I’d buy weakness in pieces only where NAND pricing, hyperscaler capex, and margins are firming; own it, don’t trade it.

Qty # 50 · Last Price $579.43 · Value $28,971.50 · Total Cost $31,833.90

Semicap equipment is the AI capex tollbooth, but with no fresh catalyst and the position down 8.99%, AMAT is a hold, not a hero add. I’d stay long, buy weakness only in pieces, and watch China exposure, HBM spending, and foundry capex before adding size.

Qty # 20 · Last Price $529.14 · Value $10,582.80 · Total Cost $11,541.60

Semis are getting hit on a Micron memory scare, but AMD is not a memory house; the real fight is MI-series share, HBM access, CoWoS supply, and AI margins. I stay long in a smaller other-holdings slot, buy weakness in pieces, and trim rips until AMD proves it can take share against Nvidia’s H200 China push.

-27.90%

Qty # 30 · Last Price $239.38 · Value $7,181.40 · Total Cost $9,960.00

The trade is on in power infrastructure, and BE sits right in the bottleneck: AI data centers need clean, on-site electrons because the grid is missing supply targets. I like holding it, not chasing it, because Oracle-style emissions pressure supports fuel cells, but that -27.90% position says buy weakness in pieces and demand margin proof.

Qty # 25 · Last Price $1,055.28 · Value $26,382.00 · Total Cost $27,230.50

Power and grid are still the scarce-capacity trade, and GEV sits right in it with turbines, electrification, grid power, and service margins. With no fresh headline and the position down 3.12%, I would not force it today; own it, don’t trade it, and add only on real weakness.

Qty # 150 · Last Price $102.99 · Value $15,448.50 · Total Cost $19,863.49

Semis are getting hit by China-memory fear, but Intel is not a Micron story; it is a yield, capex, and in-house execution story around Nova Lake. I like the turnaround as a hold: own it, don't trade it, buy weakness in pieces, and demand proof that better yields flow into margins instead of another capex sink.

Qty # 90 · Last Price $206.26 · Value $18,563.40 · Total Cost $27,788.00

Semis are getting hit by the Micron China fear tape, but MRVL is a custom silicon and optical data-center story, not a commodity DRAM story. With the position down 33%, own it, don’t trade it, and add only in pieces while hyperscaler capex and AI ramp margins stay intact.

Qty # 2 · Last Price $135.27 · Value $270.54 · Total Cost $419.81

Space and defense is a brutal tape when scarcity value breaks, and SPCX below IPO price says the market wants cash flow, margins, and proof from Starlink, not stories. Do not average down blindly here; hold only what Marco can tolerate, wait for a real catalyst, and make the stock earn fresh capital.

Qty # 20 · Last Price $419.48 · Value $8,389.60 · Total Cost $9,528.00

Semis are still the AI toll road, and TSMC just proved it with a 77% Q2 profit jump that says demand, pricing, and utilization are overpowering capex fears. Down 11.95% in the position, I’d stay long and buy weakness in pieces, but watch customer concentration, Taiwan risk, and CoWoS/HBM capacity because that is where the pinch can hit margins.

Qty # 20 · Last Price $513.84 · Value $10,276.80 · Total Cost $15,809.28

Memory is hot, but WDC is riding SK Hynix ETF froth more than fresh fundamentals today, and I do not chase that with the position down 35%. I’d hold the core only, buy weakness in pieces after NAND and nearline HDD margins confirm, and treat this as profit-taking, not a broken thesis.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$529.14 $0.00 (0.00%)

AMD’s setup is still AI infrastructure: TSMC’s pricing power confirms advanced-node demand, but it also puts a margin tax on fabless customers like AMD. Watch MI accelerator traction, EPYC demand, and wafer-cost pass-through; I like this name on weakness, not after a chase.

BE

BLOOM ENERGY CORP COM CL A

$239.38 $0.00 (0.00%)

Clean power is hot, but Bloom still has to prove margins, backlog quality, and fuel-cell project timing are durable. At $239, I like watching customer wins and gross margin progression before chasing the Zacks Rank #1 headline; the trade is on only if fundamentals confirm.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$184.01 $0.00 (0.00%)

No fresh catalyst, so CBRS is a watch-the-sector tape, not a chase-the-print setup. I want confirmation from fundamentals next: margins, order quality, and whether demand is broadening before I say the trade is on.

GLW

CORNING INC COM

$174.41 $0.00 (0.00%)

No fresh headlines means GLW is a sector read, not a catalyst trade: watch optical fiber, display glass pricing, and AI data-center capex. I like it only on weakness; the setup needs margin proof, not a flat-tape chase.

IRDM

IRIDIUM COMMUNICATIONS INC COM

$48.67 $0.00 (0.00%)

Satellite connectivity is a real theme, but IRDM has to show service revenue durability, margin leverage, and clean capex discipline on July 22 before the trade is on. I like the setup only if management confirms demand without spending creep; otherwise it is a watch, not a chase.

LITE

LUMENTUM HLDGS INC COM

$752.00 $0.00 (0.00%)

Optical is the tape to watch: AI data-center spend needs lasers, transceivers, and tight supply discipline, and LITE only works if orders convert into margin power. No fresh headlines means no chase here; watch bookings, pricing, and customer concentration, then buy weakness in pieces if the fundamentals confirm.

LRCX

LAM RESEARCH CORP COM NEW

$335.43 $0.00 (0.00%)

No fresh tape, no changed setup. Semi equipment is a capex call, so watch memory spending, China export controls, and whether HBM demand keeps pulling orders through Lam’s etch franchise.

NVDA

NVIDIA CORPORATION COM

$212.50 $0.00 (0.00%)

The sector read is simple: sovereign AI capex is still pointed straight at NVIDIA’s full stack, and Japan’s Vera Rubin factory keeps demand alive beyond hyperscalers. Watch margins and supply first, HBM, CoWoS, optical, grid power, because at $212.50 flat on the day the setup is unchanged: I like this name here.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$133.76 $0.00 (0.00%)

No real PLTR headline here, so the stock is marking time while the AI software sector waits for hard evidence of enterprise adoption turning into margin leverage. Watch revenue durability, government-commercial mix, and whether AIP demand keeps compounding; I like the name, but I would not chase a flat tape without a fresh catalyst.

PWR

QUANTA SVCS INC COM

$648.84 $0.00 (0.00%)

PWR is still a grid-power and electrification kingpin, so with no fresh headlines the watch is backlog quality, utility spend, data-center power demand, and labor/material cost discipline. At $648.84 after a flat tape, the setup is unchanged: I like this name on pullbacks, but I want margin durability before calling the trade on.

Q

QNITY ELECTRONICS INC COMMON STOCK

$140.23 $0.00 (0.00%)

No fresh headlines and a flat $140.23 print say there is no new trade signal in Q today. Watch margins, demand durability, and capex discipline; without a catalyst, this is monitor, not chase.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$293.40 $0.00 (0.00%)

This headline is noise for SIMO; it’s SVB litigation, not the NAND controller cycle. Watch flash demand, controller pricing, and OEM customer concentration, because the trade only works if storage volumes and margins reaccelerate.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$419.48 $0.00 (0.00%)

Semis are the AI-infrastructure toll road, and TSM is the gatekeeper on leading-edge wafers, CoWoS packaging, and HBM demand. At $419.48 and flat today, the setup changes nothing: watch capex, gross margin, and Nvidia/Apple concentration, because weakness tied to noise is a buy-the-dip setup.
