Qty # 60 · Last Price $937.00 · Value $56,220.00 · Total Cost $63,243.50

Semis are getting hit by macro risk and AI trade angst, but MU’s bull case is HBM demand, tighter DRAM supply, and AI server memory content. Down 11% in the position, I stay long and would buy weakness in pieces; this is own it, don’t trade it unless pricing rolls over.

-26.50%

Qty # 10 · Last Price $1,673.97 · Value $16,739.70 · Total Cost $22,775.00

Storage is still the AI bottleneck trade: DRAM and NAND supply is tight, prices are rising, and that supports SNDK margins even with Samsung and SK Hynix throwing massive capex at the shortage. The -12.6% air pocket is macro panic from US-Iran, not thesis damage, so I would stop adding size blindly but stay long and buy weakness only in pieces.

Qty # 20 · Last Price $534.39 · Value $10,687.80 · Total Cost $11,541.60

AI semis first: AMD’s problem is not the chip, it’s the software moat, and a tiny CUDA compiler beating AMD’s own tools is a direct shot at ROCm. Meta’s AI capex keeps the river running, so I’d buy AMD weakness in pieces here, but this stays a show-me holding until MI-series wins prove real margin power.

BE

Total Gain %
-29.67%

Qty # 30 · Last Price $233.49 · Value $7,004.70 · Total Cost $9,960.00

Clean power is a grid-capacity trade, but these headlines give me no Bloom-specific catalyst, so the 4.55% drop is noise, not a thesis changer. At down 29.67% in the position, I’d stay small and make BE prove it with margin progress, backlog quality, and real power-demand wins before adding.

Qty # 25 · Last Price $1,042.60 · Value $26,065.00 · Total Cost $27,230.50

Power equipment is the sector, and with no fresh headlines this is multiple compression, not a broken grid-power thesis. Own it, don't trade it, but at $1042 I add only on real weakness because margins, backlog quality, and turbine demand have to stay pristine.

Qty # 150 · Last Price $103.12 · Value $15,468.00 · Total Cost $19,863.49

Semis are splitting into AI winners and capex sinkholes, and Intel’s $5.7 billion Ireland spend screams margin pressure before it screams payoff. Stay disciplined: trim strength, demand real foundry customer proof, and keep fresh money in cleaner AI-infrastructure winners.

Qty # 90 · Last Price $217.53 · Value $19,577.70 · Total Cost $27,788.00

Semis are repricing July's AI froth, and MRVL is getting hit because custom silicon and optical growth still need clean capex digestion and margin proof. At down 30% on the position I would not puke it into a risk-off tape, but this is a show-me holding: stay long only if you believe AI data-center capex keeps feeding MRVL's pipeline.

Qty # 2 · Last Price $139.14 · Value $278.28 · Total Cost $419.81

Space is getting de-risked fast: SPCX is no longer a momentum darling, and the trade is on valuation compression, not a broken launch or Starlink story. I’d keep only a right-sized core here and buy weakness in pieces only if margins, capex discipline, and launch cadence stay intact.

-11.51%

Qty # 20 · Last Price $421.58 · Value $8,431.60 · Total Cost $9,528.00

Semis first: TSM's June sales beat says AI wafer demand and advanced packaging are still pulling, so the -2.89% move is noise, not a thesis break. I stay long and buy weakness in pieces, with focus on gross margins, CoWoS capacity, HBM partners, and customer concentration before adding size.

WDC

-29.72%

Qty # 20 · Last Price $555.55 · Value $11,111.00 · Total Cost $15,809.28

WDC is getting pulled down with semis on macro fear, but the real story is storage-cycle torque: NAND pricing, enterprise SSD demand, and AI data growth beat the Iran headline noise. With the position down 29.72%, I’d buy weakness in pieces, not chase, because this is a cyclical memory winner for the second half setup, booyah.

Watchlist

AMD

ADVANCED MICRO DEVICES INC COM

$534.39 -$23.50 (-4.21%)

Chips are getting hit by oil, geopolitics, and earnings anxiety, but AMD’s real scoreboard is AI accelerator demand, gross margin, HBM supply, and CoWoS access. The trade is on only if earnings show data-center acceleration; otherwise this dip is a warning, not a gift.

BE

BLOOM ENERGY CORP COM CL A

$233.49 -$11.12 (-4.55%)

Energy tech first: this Forbes lending headline is not a BE catalyst, so the 4.55% hit needs real Bloom-specific order flow to matter. Watch data-center power wins, service margins, grid bottlenecks, and electrolyzer demand; I like the theme, but the name has to earn $233 with fundamentals.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$204.62 -$10.46 (-4.86%)

No fresh news, so this is just heat coming out of the AI accelerator trade, not a broken story. Watch margins, customer concentration, and supply-chain access to HBM and advanced packaging; I like the setup only if weakness comes with clean demand, not hype.

IRDM

IRIDIUM COMMUNICATIONS INC COM

$48.59 -$1.47 (-2.94%)

Space telecom is hot, but this ARK headline is money chasing SpaceX, not a clean IRDM catalyst, so the 3% dip does not change the setup. Watch service revenue, government and maritime demand, direct-to-device competition, and margin leverage from the existing constellation; I like IRDM only if those fundamentals beat the space-sector hype.

LITE

LUMENTUM HLDGS INC COM

$768.15 -$33.86 (-4.22%)

LITE is an optical-AI infrastructure name, so watch datacenter demand, hyperscaler concentration, and margins through lasers and transceivers. With no fresh headline, today’s 4% drop is not the trade; buyable weakness needs bookings confirmation, not just booyah off the chart.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$130.04 $3.25 (2.56%)

PLTR is riding the defense-AI software bid, but the headline that matters is a Palantir rival landing U.S. deals because contract momentum drives the multiple here. Watch federal deal flow and commercial margin leverage; at $130 after another green day, I like the theme but I’d wait for weakness before chasing, booyah.

PWR

QUANTA SVCS INC COM

$646.70 -$11.86 (-1.80%)

Power infrastructure is still the sector to watch: grid hardening, data-center load, utility capex, all right in PWR’s wheelhouse. A 1.8% down day with no fresh headlines does not change the setup; watch backlog conversion and margins, and buy weakness only in pieces.

Q

QNITY ELECTRONICS INC COMMON STOCK

$140.98 -$2.82 (-1.96%)

No fresh headlines means this is sector tape, not a company-specific reset; the down 1.96% move does not change the setup. Watch semicap materials demand, HBM and advanced-packaging exposure, China friction, and post-spin margin cleanup; I like this name only on weakness.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$299.51 -$26.84 (-8.22%)

This tape gives no real SIMO-specific headline, so an 8% drop reads like sector and positioning pressure in storage semis; watch NAND demand, gross margin, and customer concentration. I’d wait for the earnings guide and inventory commentary before chasing weakness, because the trade is on only if margins hold and AI/server SSD pull-through shows up.
