Qty # 20 · Last Price $958.73 · Value $19,174.60 · Total Cost $18,565.95

Memory is the AI toll booth right now, and Micron is getting paid as HBM tightness, pricing power, and less brutal cycle discipline push margins higher. Stay long, buy weakness in pieces, but do not chase every green tick after a 2.77% pop because the trade is on only while AI capex keeps feeding DRAM demand.

-2.68%

Qty # 20 · Last Price $220.78 · Value $4,415.60 · Total Cost $4,537.18

AI semis are still the sector, and NVDA’s Q2 strength says demand, margins, and accelerator pull-through remain bigger than the near-term volatility. I’d stay long and buy weakness in pieces because the trade is on, but Marco executes.

Qty # 10 · Last Price $1,566.70 · Value $15,667.00 · Total Cost $17,217.75

Storage is the AI buildout sleeper, and SanDisk at 7 times forward earnings is still being priced like the memory cycle dies tomorrow. Position is red, stock is ripping today, so I would not chase the 5.5% move; buy weakness in pieces if NAND pricing and AI storage demand keep tightening.

4.52%

Qty # 100 · Last Price $164.58 · Value $16,458.00 · Total Cost $15,746.75

Semis first: SK hynix is an AI memory levered story, and the market is paying for HBM strength, margins, and tight supply, not a generic fair-value screen. At $164.58 up 2.20% today and +4.52% on the position, I’d stay long but buy weakness in pieces, because the trade is on as long as HBM demand and capacity discipline hold.

Qty # 30 · Last Price $367.95 · Value $11,038.50 · Total Cost $9,949.00

Autos are back in play today, but TSLA at +5.5% is still a fundamentals fight over volume growth, margin pressure, autonomy credibility, and battery cost curves. I’d stay long but not chase this spike; buy weakness in pieces if the EV demand story and AI/robotaxi optionality keep improving.

Watchlist

AVGO

BROADCOM INC COM

$370.34 $1.55 (0.42%)

AVGO is still a premier AI infrastructure toll-taker, but at $370 you need fiscal Q3 to confirm the VMware margin lift, custom silicon demand, and networking backlog are all still firing. Watch the earnings guide like a hawk; if HBM, optical, or hyperscaler capex commentary stays hot, the trade is on.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$184.24 $5.16 (2.88%)

AI accelerators are still the battleground, and Cerebras has the sizzle, but I want proof on real hyperscaler demand, margins, and whether supply constraints like advanced packaging can scale cleanly. The move does not break the setup; watch whether that $291 target is backed by revenue acceleration, because without customers and gross margin leverage, it is just heat, not earnings power.

GLW

CORNING INC COM

$148.73 $0.03 (0.02%)

GLW is a materials-and-optical infrastructure watch, and a flat tape into the ex-dividend date says this is income support, not a fresh catalyst. Watch the real drivers: optical demand, display glass pricing, margin leverage, and whether AI data-center buildouts pull more fiber through Corning’s pipeline.

GOOGL

ALPHABET INC CAP STK CL A

$339.35 -$7.24 (-2.09%)

GOOGL is still an AI and ads compounder, but the market wants proof that search margins can hold while cloud capex keeps climbing. Watch the next print for cloud acceleration, Gemini monetization, and whether YouTube keeps taking ad dollars; if those hit, I like this name here.

IRDM

IRIDIUM COMMUNICATIONS INC COM

$46.98 $0.38 (0.82%)

Satellite comms is a niche infrastructure story, and without fresh headlines the setup is about service revenue durability, handset/device demand, and whether capex stays disciplined. I like watching IRDM on weakness, but the trade is on only if margins hold and management keeps proving the cash flow story.

LITE

LUMENTUM HLDGS INC COM

$914.76 $19.76 (2.21%)

AI optics is the trade, but this headline says Lumentum is being singled out, not the whole group, so watch whether orders and margins confirm real share gain in optical interconnects. I like the setup only if the CoWoS/HBM buildout keeps pulling higher-speed transceivers through the supply chain; otherwise this move is just momentum wearing an AI badge.

LRCX

LAM RESEARCH CORP COM NEW

$301.49 -$0.41 (-0.14%)

Semicap equipment is hostage to memory capex, and LRCX needs NAND and DRAM spend to firm up before the trade really gets paid. The insider-sale headline is noise under a 10b5-1 plan; watch wafer-fab equipment orders, China exposure, and whether AI memory demand pulls Lam’s etch and deposition stack higher.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$186.38 $0.09 (0.05%)

Software and AI infrastructure are still the right pond, but PLTR at $186 needs revenue growth and government-to-commercial conversion to justify that premium. Watch the margins, watch customer concentration, and buy weakness only if the AI platform keeps turning pilots into real contracts.

PWR

QUANTA SVCS INC COM

$607.09 $4.39 (0.73%)

PWR is a grid power and electrification toll road, and the move says investors still want exposure to transmission, data-center load, and utility capex. Watch backlog quality and margins on high-voltage equipment work, because if execution stays clean, I like this name on weakness, booyah.

Q

QNITY ELECTRONICS INC COMMON STOCK

$119.43 -$0.75 (-0.62%)

Materials and electronics supply chain name, so the tell is shareholding quality plus whether end-demand in semis can support margins after the spin-style hype fades. I’d watch the report, wait for real institutional sponsorship and clean earnings power, and only buy weakness if the fundamentals say the trade is on.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$246.84 $1.03 (0.42%)

SIMO is a niche storage-controller semiconductor watchlist name, and this headline is noise because it is tokenized-stock plumbing, not fundamentals. Watch NAND demand, gross margins, and customer concentration; the setup only gets interesting if real semiconductor orders confirm the move.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$415.32 -$2.20 (-0.53%)

TSM is still the toll road for AI silicon, but this headline says Taiwan wants investors to broaden the lens beyond one mega-cap and into the full supply chain. Watch CoWoS, HBM packaging, power constraints, and customer concentration, because if those stay tight and Apple/Nvidia/AMD demand holds, I like this name on weakness.
