Qty # 20 · Last Price $958.16 · Value $19,163.20 · Total Cost $18,565.95

Memory is the sector tell: AI demand is real, but MU still has to prove pricing power and HBM margin durability before I chase a stumble. I’d stay long, buy weakness in pieces, and keep the eye on HBM supply, capex discipline, and whether cloud orders stay hot.

Qty # 20 · Last Price $228.45 · Value $4,569.00 · Total Cost $4,537.18

AI semis remain the lead sector, and NVDA still has the cleanest demand story if hyperscaler capex keeps feeding GPUs, networking, HBM, CoWoS, and power-hungry data centers. At $228.45 after a green day, I would stay long but buy weakness in pieces, because this is still own it, don’t trade it unless the spending cycle cracks.

-9.69%

Qty # 10 · Last Price $1,554.99 · Value $15,549.90 · Total Cost $17,217.75

Storage is still in the AI buildout lane, and SNDK’s drawdown looks more like multiple reset than thesis break because data centers need capacity, bandwidth, and power-hungry infrastructure. I’d stay long but buy weakness in pieces, because the trade is on only if NAND pricing and AI storage demand keep margins moving the right way.

3.95%

Qty # 100 · Last Price $163.68 · Value $16,368.00 · Total Cost $15,746.75

Memory is the sector to watch, and SKHY is still an HBM/AI capex story with Japan plant optionality adding supply-chain leverage but also spending risk. I like the name, but after a modest gain in the position I would stay long and buy weakness in pieces, not chase a tight-range tape.

TSLA

13.49%

Qty # 30 · Last Price $376.37 · Value $11,290.95 · Total Cost $9,949.00

Autos are back in charge today, and TSLA gets the bid because Q2 revenue growth says demand is not dead despite recall noise out of China. I like holding it, not chasing a 5% up day; buy weakness in pieces because the Cybercab story only works if margins, batteries, and manufacturing execution keep improving.

Watchlist

AVGO

BROADCOM INC COM

$357.16 -$10.08 (-2.74%)

Semis first: AVGO is an AI infrastructure toll collector, but this tape is demanding proof in margins, AI backlog, and custom silicon demand after earnings. Watch the guide, not the day-one swing; if HBM, CoWoS, and hyperscaler orders stay tight, I like this name on weakness, booyah.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$190.44 $5.92 (3.21%)

AI compute is the sector, and the Finland deal says Cerebras is chasing sovereign data-center demand while the market still wants proof on margins, power access, and chip supply. I like the watchlist setup only on weakness because the move is already hot today, but Cathie Wood buying keeps the speculative bid alive.

GOOGL

ALPHABET INC CAP STK CL A

$342.48 $5.36 (1.59%)

GOOGL is still an AI capex debate first and an ad/search compounder second, so watch whether spending turns into real product dominance instead of margin pressure. I like the setup only if the market starts rewarding AI monetization, because right now the trade is on for proof, not promises.

LITE

LUMENTUM HLDGS INC COM

$847.37 -$23.21 (-2.67%)

Optical is still one of the hottest AI plumbing lanes, but a planned insider sale after prior selling is a yellow flag, not a thesis-killer. I’d watch whether demand for datacenter transceivers and components keeps margins expanding; if that cracks, the trade is off.

LRCX

LAM RESEARCH CORP COM NEW

$292.66 $4.34 (1.51%)

Semi equipment is still a capex-cycle call, and LRCX needs memory and foundry spend to keep firm before I’d chase a green day. The insider sale looks like vesting and option mechanics, so the real watch is orders, margins, and whether wafer fab equipment demand keeps broadening.

PWR

QUANTA SVCS INC COM

$620.06 $9.28 (1.52%)

Power and grid infrastructure remain the bull market under the AI bull market, and Quanta is levered to the real bottleneck: transmission, substations, utility capex, and data-center power. At 37.7x forward earnings after a push to $620, I like the company more than the price here; watch for backlog growth and margin discipline, buy weakness in pieces, booyah.

Q

QNITY ELECTRONICS INC COMMON STOCK

$118.47 $0.78 (0.66%)

Materials and electronics packaging are where AI demand gets real, but this headline says valuation is already doing heavy lifting. Watch whether Qnity can turn those packaging slurries into margin-accretive wins; otherwise the trade is on only after a pullback.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$235.70 -$6.81 (-2.81%)

Semis first: this is a controller name, so I’m watching NAND demand, client SSD pricing, and inventory digestion, not a thin tokenized-stock price blip. Down 2.8% on no real company headline does not change the setup; I’d wait for fundamentals before calling the trade on.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$417.01 $1.51 (0.36%)

TSM is the toll road for AI silicon, but today’s flat move says the market is looking through Taiwan tape weakness and staying focused on CoWoS capacity, HBM attach, and Apple/Nvidia demand. Watch margins and capex discipline; I like this name on pullbacks, but the trade is patience, not chasing.
