Qty # 5 · Last Price $1,551.99 · Value $7,759.95 · Total Cost $8,557.80

The AI storage trade is still on, but after a 500% run SNDK is getting punished as investors reassess the buildout’s pace. Stay long, don’t chase, and buy weakness in pieces because AI demand still needs massive storage capacity—booyah.

Qty # 120 · Last Price $175.63 · Value $21,075.60 · Total Cost $19,252.75

SKHY’s 7.6% drop after a powerful run says momentum cracked at the highs, and a 9.5% position gain is worth protecting. I’d trim here and keep only a smaller stake until support proves real—don’t let a winner turn into dead money.

EV growth is real with Q2 revenue up 25.52%, but Optimus and robotaxi hype still carries more narrative than proven economics. Stay long, don’t chase—buy weakness in pieces and demand margin expansion before adding aggressively.

Watchlist

AVGO

BROADCOM INC COM

$344.72 -$17.27 (-4.77%)

AVGO’s 4.77% drop improves the setup, but the real tell is whether AI networking and custom-silicon growth can offset customer concentration and heavy capex demands. I like this name on further weakness in pieces—the AI infrastructure trade is still on.

CBRS

CEREBRAS SYSTEMS INC COM CL A

$181.21 -$10.72 (-5.59%)

Cathie Wood is buying the weakness, but a 5.59% drop says the market still wants proof that Cerebras can diversify customers and scale gross margins. Watch bookings and supply-chain execution; the AI-accelerator trade is on, but CBRS has to earn the premium.

GOOGL

ALPHABET INC CAP STK CL A

$349.39 $10.89 (3.22%)

Alphabet’s 3.22% rebound says the regulatory scare is not breaking the AI-and-cloud setup, but legal exposure remains the headline risk to watch. I like this name on the watchlist, but don’t chase the bounce—wait for clarity on remedies and any hit to search economics.

LITE

LUMENTUM HLDGS INC COM

$835.03 -$92.00 (-9.92%)

LITE’s 9.9% drop after a 114% year-to-date surge resets the setup, but the optical trade is still on as AI data centers demand faster links. Watch U.S.-China regulatory risk and whether margins keep pace with capacity spending; I like this name only on disciplined weakness.

LRCX

LAM RESEARCH CORP COM NEW

$273.49 -$24.73 (-8.29%)

Semiconductor equipment is getting crushed across the board, so LRCX’s 8% drop does not signal a company-specific breakdown. Watch memory and HBM capex demand; if spending stays firm, I like this name on the watchlist after the washout.

PLTR

PALANTIR TECHNOLOGIES INC CL A

$173.31 $6.08 (3.64%)

PLTR’s 3.64% pop does not make a $173 stock undervalued; watch revenue growth, margins, and commercial customer expansion. I like the AI platform, but the valuation demands flawless execution—buy weakness, not excitement.

PWR

QUANTA SVCS INC COM

$622.02 -$28.56 (-4.39%)

PWR is still a prime grid-capex play, but watch backlog growth, labor costs, and margin conversion after today’s 4.39% drop. I like this name on the watchlist; the setup holds unless utility spending or project execution cracks.

SIMO

SILICON MOTION TECHNOLOGY CORP SPONSORED ADR

$236.81 -$47.67 (-16.76%)

SIMO’s 16.8% plunge resets the valuation, but the setup still rides the NAND cycle and demand for storage controllers rather than the cleanest AI infrastructure bottlenecks. Watch controller margins, customer concentration, and NAND pricing before chasing—if those hold, I like this name on stabilization, not during the free fall.

TSM

TAIWAN SEMICONDUCTOR MANUFACT SPONSORED ADS

$418.01 -$15.23 (-3.52%)

Semis are still the trade, and four straight sessions of foreign buying in Taiwan say institutional demand remains intact despite TSM’s 3.52% drop. Watch whether those inflows persist and broaden beyond panels into foundry leaders; if they do, I like TSM on weakness.
