AI chip trade just hit the brakes

The trade everyone loved is suddenly wobbly

For the last 14 months, Wall Street treated the AI rally like a two-step dance: step into semiconductors, sidestep software. That play was crushing it. But in July, the relationship blew up — the SOXX/IGV ratio is down nearly 20% month-to-date, which is the kind of move that makes momentum traders spill coffee on their keyboards.

Chips got punched, software got a pass

The chip complex has taken a bruising. Marvell, Astera Labs, Teradyne, and Intel are all down sharply, while Nvidia is the lone green speck in a sea of red. Meanwhile, the software ETF is up on the month, which is basically the market saying, “Wait, maybe the whole AI stack isn’t one giant one-way trade.”

What changed?

A few things hit at once:

• positioning got crowded after a monster run;
• investors started questioning whether hyperscalers can keep hiking AI capex at the same pace;
• and a new open-weight model from Moonshot AI stirred up the uncomfortable idea that frontier-ish AI could get cheaper and more accessible.

That matters because if the models get easier to run, the chip gravy train may not be as automatic as the bull case assumed.

Not a fundamentals problem — yet

Here’s the weird part: this hasn’t been a classic earnings panic. The article says semiconductor estimates haven’t really come down; the pain has been about valuation, not the actual numbers. Translation: the market is de-rating the sector before the spreadsheet boys and girls have even had time to revise their models.

Software is getting the opposite treatment. It’s still not exactly cheap-cheap, but it’s no longer priced like every app company is about to be replaced by a chatbot in a trench coat.

Big picture: this may just be a pause in the AI megatrend, not a funeral. But if hyperscaler spending cools off or second-quarter earnings disappoint, this rotation could have legs.
