AI storage demand is turning Sandisk from a pure memory cyclical into an infrastructure beneficiary, but a 2,440% run leaves zero room for a NAND pricing or capex stumble. Stay long, don’t chase—buy weakness in pieces below 24 times trailing earnings.

Tesla’s 25.5% Q2 revenue growth keeps the AI, Optimus, and robotaxi story alive, but $365 already prices in years of flawless execution. Stay long for optionality, but I’d trim strength until margins and real autonomy revenue catch up with the valuation.

Watchlist

CBRS

CEREBRAS SYSTEMS INC COM CL A

$191.93 $0.00 (0.00%)

Cathie Wood’s $17.2 million buy says the AI-accelerator trade is still on, but one fund’s conviction does not validate the business. Watch customer concentration, gross margins, and access to advanced packaging before chasing CBRS at $191.93.

GOOGL

ALPHABET INC CAP STK CL A

$338.50 $0.00 (0.00%)

Regulatory pressure is driving the slide, but the real tell is whether legal remedies threaten Search distribution or AI-driven margins. At $338.50, the setup is unchanged: watch the legal fallout and cloud growth before buying the weakness.

LITE

LUMENTUM HLDGS INC COM

$927.03 $0.00 (0.00%)

Lumentum is an optical-AI infrastructure play, so watch datacenter demand, customer concentration, and whether any U.S.-China action tightens the supply chain or hits revenue exposure. After a 114% year-to-date surge, the setup demands accelerating margins and orders—don’t chase it here; buy weakness only if the fundamentals keep compounding.

LRCX

LAM RESEARCH CORP COM NEW

$298.22 $0.00 (0.00%)

Wafer-fab equipment is the AI infrastructure trade, and LRCX has real leverage to HBM and advanced packaging with record revenue and expanding margins. After a near-tripling, don’t chase—watch margin durability and buy weakness in pieces.

PWR

QUANTA SVCS INC COM

$650.58 $0.00 (0.00%)

The grid-power buildout keeps the trade on for Quanta as utilities upgrade transmission and data centers strain electricity infrastructure. Watch backlog growth, labor costs, and execution margins; I like this name on weakness, not at any price.
