Semis are risk-on, and a 13% rip in AMD says the market is paying for AI accelerator leverage, not short-term noise. Watch margins, MI-series customer breadth, HBM and CoWoS supply, and capex discipline; chase nothing here, buy weakness if the AI server story keeps accelerating.

• What's Going on With Broadcom Stock Friday?

Semis are in charge and AVGO is acting like AI infrastructure is still the trade, with custom silicon, networking, and VMware margin leverage driving the setup.

Fuel cells are back in the AI power trade, and BE’s 26% rip says the market is paying up for onsite power, margin expansion, and hyperscaler demand after that ugly sector washout.

• Kaplan Fox Encourages Investors of Cerebras Systems Inc. (CBRS) Who Suffered Losses to Contact the Firm Regarding a Securities Investigation

• Lumentum Holdings Stock (LITE) Opinions on AI Infrastructure Selloff

Optical is back in the AI infrastructure trade: 90% revenue growth says Lumentum is selling real picks-and-shovels into data-center capex. After a 15% rip, watch margins and customer concentration next because the trade is on only if operating leverage follows the revenue, booyah.

• Dear Lam Research Stock Fans, Mark Your Calendars for July 29

Semicap just sent a message: LRCX is ripping because the beat-and-raise was real, with AI memory and NAND capex pulling revenue and guide higher. Watch HBM, NAND wafer starts, China controls, and AMAT/KLAC confirmation; I like this name on pullbacks, not after an 18% chase.

• Prediction: Nvidia Stock Hasn't Peaked. It Is Going to $500 by 2029 | The Motley Fool

The AI semiconductor trade is still on, but a $500-by-2029 call only works if Nvidia keeps turning HBM, CoWoS access, networking, and Blackwell demand into margin-rich revenue. Watch hyperscaler capex and supply-chain bottlenecks first; I like this name on weakness, not after a straight-line chase.

• Prediction: Palantir's Stock Will Make a Huge Move on Aug. 3

Enterprise AI software is still in favor, but PLTR at $122.26 needs a flawless Aug. 3 print: accelerating U.S. commercial growth, durable government demand, and margins that justify the multiple. Watch earnings reaction, not the 60-basis-point dip; if guidance stumbles, the trade is lower, and if they raise cleanly, the premium multiple gets defended.

• Silicon Motion Technology (Nasdaq:SIMO) - Stock Analysis - Simply Wall St

Semis are still the trade, and SIMO’s 22% rip says the market is paying up for controller exposure tied to hyperscaler and neo-cloud storage spend. Watch margins and design wins now, because after that monster YTD move I like the theme but I would not chase without proof the demand is durable.
