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

Memory is the AI semi tell: HBM and high-end DRAM stay central, but China competition fear attacks future gross margins and that is why MU is acting broken. At a 19% position drawdown, I would not panic-sell; I would buy weakness in pieces only if the AI memory pricing thesis stays intact, because this is own it, don't trade it territory.

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

Storage is still an AI infrastructure trade, but SNDK is getting hit with profit-taking across memory, not a broken thesis. Down 38% in the position, I would buy weakness only in pieces and demand proof that margins and enterprise AI storage demand are turning before getting aggressive.

-11.90%

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

Semicap is a capex cycle, and with no fresh headlines on AMAT, the real drivers are foundry spend, China restrictions, advanced packaging, and memory recovery. Down 11.90% in the position, I’d hold core exposure but trim rallies until orders and margins prove the next upcycle is real.

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

Semis are getting hit by a memory fear, but AMD is not a DRAM house; the real story is AI accelerator share, HBM/CoWoS access, and server CPU margins. At -13% on the position, I would not panic-sell a sympathy downdraft; own the core, trim only if the AI backlog or gross-margin path breaks.

-37.73%

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

Data-center power is the story, and Oracle cutting emissions around Project Jupiter keeps clean onsite generation in the conversation for Bloom Energy. BE still has execution risk after a 37.73% position drawdown, so I’d hold core only and demand real backlog, margins, and grid-power wins before adding.

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

Power equipment and grid electrification remain the scarce-capacity trade, and with no fresh headlines the GEV story is backlog, pricing, turbine execution, and grid capex. Position is red but the sector is strong: stay long, buy weakness in pieces, own it, don’t trade it.

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

Semis are getting hit on China memory fear, but INTC’s real fight is execution: foundry margins, capex burn, and proving AI/server relevance. At -26.77%, keep it on a short leash, trim rallies, and make management earn any add.

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

Semis are being sold as one basket on China memory fear, but MRVL is an AI infrastructure name built on custom silicon, optical, and data-center capex, not a DRAM knife fight. At a 39% drawdown, I’d buy weakness in pieces and own it, don’t trade it, because the trade is on when the group stops confusing Marvell with Micron.

Total Gain %
-37.54%

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

Space is a brutal sector when the headline flow is only broken-price action and no new margin, launch cadence, contract, or cash-flow catalyst. At -37.54%, I would not average down just because SPCX is below IPO; this stays in the penalty box until fundamentals say the trade is on.

-13.99%

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

AI semis are still the trade, and TSMC beating Q2 plus raising capex and revenue guidance says leading-edge demand is real, not hype. I like this name on weakness in pieces despite the 13.99% position drawdown, because customer pull and capacity spend matter more than a flat tape today.

-40.94%

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

Memory and storage are in a sell-the-winners reset, and WDC is getting hit with the chip tape after profit-taking in SK Hynix and SanDisk. Do not chase at $466.81 with the position down 40.94%; buy weakness in pieces and demand proof that HDD margins, cloud capex, and supply discipline keep improving.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$500.94 $0.00 (0.00%)

This Netflix ad headline is media, not a clean AMD catalyst; the chip read is still AI capex, MI-series traction, HBM supply, and whether hyperscalers want a second source beyond Nvidia. Watch for real data-center revenue acceleration before chasing a flat tape, but if the AI order book keeps broadening, I like this name on weakness.

AVGO

BROADCOM INC COM

$374.45 $0.00 (0.00%)

AI infrastructure is still the AVGO setup, but this Reuters headline says the market is testing the hyperscaler capex runway, and that hits custom silicon, networking, and optical demand first. I like this name on weakness only; chase nothing at $374 until Broadcom proves AI backlog and VMware margin power are still expanding.

BE

BLOOM ENERGY CORP COM CL A

$206.73 $0.00 (0.00%)

BE's headline tape gives you nothing company-specific here; the setup is still grid power, data-center load, project margins, and whether fuel-cell deployments convert into durable service economics. At $206.73 with no move today, I’d watch backlog quality and margin cadence before chasing, because in clean power the trade is on only when orders turn into cash, booyah.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$180.46 $0.00 (0.00%)

No fresh headlines, no sector catalyst, no reason to chase a flat print at $180.46. Watch margins, capex needs, and customer concentration next; until the fundamentals talk, this stays watchlist only.

GLW

CORNING INC COM

$158.39 $0.00 (0.00%)

No fresh tape, so the setup is sector-first: GLW is a glass and optical infrastructure name tied to data-center fiber, display glass utilization, and auto specialty glass. I want margin expansion and optical order strength before chasing; no news means the trade is not on, just keep it on the screen.

GOOGL

ALPHABET INC CAP STK CL A

$354.46 $0.00 (0.00%)

AI platform names live and die on product cadence, and a Gemini 3.5 Pro delay hits the one place Alphabet cannot look second-rate: keeping developers and enterprise customers locked into its stack. Watch capex discipline, cloud growth, and search monetization; I like the franchise, but the trade is on only after management proves the AI roadmap is back on time.

IRDM

IRIDIUM COMMUNICATIONS INC COM

$46.61 $0.00 (0.00%)

Satellite communications is a certification story: watch whether the FAA receiver upgrade cycle pulls real aviation demand toward Iridium-enabled GNSS services or stays a Collins cleanup. At $46.61 and flat, the trade is not on yet; I like the name only if mandates convert into recurring high-margin connectivity revenue, not one-off hardware noise.

LITE

LUMENTUM HLDGS INC COM

$706.23 $0.00 (0.00%)

No fresh headlines means no new edge, so watch optical AI demand, datacom margins, and customer concentration before chasing LITE. If hyperscaler capex keeps pulling optical networking, the trade is on; if orders slip, this is a show-me name.

LRCX

LAM RESEARCH CORP COM NEW

$320.96 $0.00 (0.00%)

Semicap is the AI toll road, and Lam is a core toll collector in etch and deposition as HBM, NAND recovery, and leading-edge foundry capex lift wafer-fab intensity. At $320 with a flat tape and a noisy momentum headline, do not chase; watch orders, memory margins, and China restriction risk, then buy real weakness because this is a quality cycle name.

PWR

QUANTA SVCS INC COM

$631.02 $0.00 (0.00%)

PWR is a grid-power winner, and no fresh headlines means the setup is still about backlog, margin discipline, and utility capex. I would watch for any pullback tied to rates or construction-cost noise, because the data-center power buildout keeps this name on the buy-weakness list.

Q

QNITY ELECTRONICS INC COMMON STOCK

$135.47 $0.00 (0.00%)

Q is a watchlist name with no catalyst today, so the setup has not changed at $135.47. I’d wait for fresh evidence on margins, demand, and customer concentration before chasing; the trade is not on yet.

RDDT

REDDIT INC CL A

$185.26 $0.00 (0.00%)

Internet ads first, AI data licensing second: RDDT needs user growth, ad pricing, and high-margin licensing revenue to keep compounding. No fresh headlines and a flat tape do not change the setup; I like the story, but I’d wait for weakness or a clean earnings beat before getting aggressive.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$272.45 $0.00 (0.00%)

This SpaceX headline is not SIMO news; it is high-beta tech risk appetite noise, while Silicon Motion trades on NAND controllers, gross margins, and customer inventory turns. Watch mobile and PC SSD demand plus China concentration; I like this name only on weakness after margins confirm, not on a dead-flat print at $272.45.
