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

Memory is the AI bottleneck, and Micron’s HBM cycle, pricing power, and capex discipline matter more than one China competition scare dragging semis. The position is painful, but the trade is on: buy weakness in pieces, don’t chase green, own the AI memory cycle.

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

Memory is getting hit on ETF froth and profit-taking, not a broken AI storage thesis; NAND demand, cloud capex, and data-center power bottlenecks still keep SanDisk levered to the buildout. At down 29% in the position, I’d buy weakness in pieces and demand margin evidence because this tape is punishing anything that ran on leverage, booyah.

AMAT

-8.99%

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

Semi equipment is under pressure, and with no fresh headline to change the setup, AMAT is still a capex-cycle name tied to foundry spend, memory spend, margins, and China controls. Down 9% in the position is not a panic sell, but I would buy weakness only in pieces until orders and margins prove the turn.

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

Semis are trading as one risk bucket today, but this AMD hit is guilt by association from Micron’s China memory scare, not a direct demand read on EPYC or AI accelerators. I would stay long and buy weakness in pieces, because the real AMD debate is HBM and CoWoS capacity, margins, and AI server share, not commodity memory panic.

BE

-27.90%

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

Grid power is the AI bottleneck, and that keeps Bloom Energy in the conversation for data centers that need fast, behind-the-meter power. The trade is on, but BE is still a show-me story on margins and scale, so I’d buy weakness in pieces and refuse to chase it here.

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

Grid power is still the right sector, but with no fresh catalyst and GEV off 1%, I would not chase it at $1055.28. Stay long core, buy weakness in pieces, own it don’t trade it.

-22.23%

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

Semis are getting sold as one China-risk basket, but Intel is not a memory name, so this is sympathy pain plus political noise, not a fresh thesis breaker. I’d stop adding, demand proof on margins and foundry capex discipline, and treat any bounce as a chance to trim this Other holding.

-33.20%

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

Semis are getting whacked by China memory fear, but MRVL is not Micron; the real story is AI custom silicon, optical, and whether data-center growth can outrun carrier softness. Down 33% in the position, I would not chase hero adds today; stay disciplined, demand margin proof, and wait for the trade to come back to MRVL on fundamentals.

SPCX

Total Gain $
-$149.27
Total Gain %
-35.56%

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

Space is exciting, but this headline is pure tape damage: all-time low, below IPO price, and no margin, Starlink, capex, or launch-cadence detail to underwrite the dip. For an Other holdings sleeve, I’d cut risk or hold only a stub; the trade is not on until fundamentals, not price nostalgia, take back control.

TSM

Day's Gain $

Day's Gain %

-$1,138.40
Total Gain %
-11.95%

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

Semis first: TSM is still the AI toll road, but these headlines say positioning, not earnings power; the real tells are CoWoS capacity, HBM pull-through, grid power, and capex discipline. Down nearly 12% in the position, I’d buy weakness in pieces only if Marco wants more Taiwan and customer-concentration risk; otherwise own it, don’t trade it.

WDC

Day's Gain $
-$989.60
Day's Gain %

Total Gain %
-35.00%

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

Storage is a cyclical tape, not a broken thesis: the headlines scream profit-taking after an ETF-fueled memory squeeze, and WDC is getting punished with the group. At -35% in the position, own it, don’t trade it; I’d add only in pieces because cloud capex and storage margins matter more than hot-money ETF flows.

Watchlist

AVGO

BROADCOM INC COM

$394.28 $5.17 (1.33%)

Semis first: AVGO is the high-margin AI infrastructure toll road, with custom silicon, networking, and VMware cash flow doing the heavy lifting. Morningstar calling it undervalued keeps the watchlist setup alive, but I’d watch AI order visibility, hyperscaler concentration, and CoWoS/HBM supply before chasing a green day.

GLW

CORNING INC COM

$174.41 -$13.23 (-7.05%)

No fresh headlines means I treat this -7% GLW move as tape pressure first, not a broken story. Watch optical connectivity orders, display glass pricing, and margin flow-through; I like this name on weakness if those fundamentals stay intact.

LITE

LUMENTUM HLDGS INC COM

$752.00 -$62.80 (-7.71%)

Optical is guilty until hyperscaler capex and AI transceiver demand prove otherwise, and a 7.7% drop with no fresh headline says the tape is testing conviction. Watch margins, backlog, and supply-chain pinch points; I like this name only on proof, not hope.

NVDA

NVIDIA CORPORATION COM

$212.50 $0.70 (0.33%)

AI semis are still the power sector, and NVDA is resting while the business keeps doing the heavy lifting. Watch data-center margins, HBM and CoWoS supply, and hyperscaler capex; if those stay strong, I like this name on weakness.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$133.76 $0.04 (0.03%)

AI defense software is still a premium-multiple lane, and this flat tape says PLTR needs fresh proof: AIP conversion, federal budget follow-through, and operating leverage. I like the franchise, but at $133.76 the setup is watchlist-only: buy weakness in pieces, don’t chase a no-news move off a SpaceX headline.

PWR

QUANTA SVCS INC COM

$648.84 -$12.10 (-1.83%)

Grid infrastructure is still the story: PWR is a premium play on utility capex, data-center power demand, and transmission bottlenecks, and this 1.8% dip is noise without fresh headlines. I’d watch backlog quality, margin conversion, and transformer or labor pinch points; buy weakness in pieces only if the capex cycle stays intact.

Q

QNITY ELECTRONICS INC COMMON STOCK

$140.23 -$1.44 (-1.02%)

No fresh headlines, so Q is just drifting with the tape at $140.23, down 1%, and the setup has not changed. Watch the next print for margin durability, capex discipline, and customer concentration; without that, the trade is not on, booyah.

RDDT

REDDIT INC CL A

$198.03 -$5.24 (-2.58%)

Social media is an ad-cycle and data-licensing sector story, and this Valve parts headline is not a Reddit thesis changer. The 2.6% dip is noise; watch engagement, ad pricing, AI licensing, and moderation costs, because I like RDDT only if those fundamentals stay hot.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$293.40 -$15.01 (-4.87%)

Semis are getting hit, and this SILITH/UMC photonics headline does not directly change the SIMO setup. For SIMO, watch NAND controller demand, SSD inventory digestion, gross margin discipline, and whether AI storage pull-through finally shows up in numbers.
