Yesterday, U.S. stock futures saw a collective surge in chip stocks, but note that the biggest rally this time was not NVIDIA, but Micron Technology, which jumped over 5%.

ARM and SanDisk followed with a 5% increase, AMD and Western Digital rose over 4%, and even Qualcomm and Intel gained more than 3%.

The rapid rise is because there is a very important hidden factor behind it.

This timing is very delicate.

On June 15th, just one week before Micron’s earnings report, funds collectively rushed to front-run, indicating what?

It suggests that the market is betting early on a signal:

The memory chip cycle has completely reversed.

Look at who is leading the rally?

Micron makes memory, SanDisk and Western Digital produce flash storage and hard drives, Seagate makes mechanical hard drives.

It’s not the traditional GPU computing crowd leading the rally.

This is the core point:

Funds are shifting from “computing power” to “storage capacity.”

Over the past year, everyone focused only on NVIDIA, thinking AI is all about computing power.

But now the logic has changed.

If data cannot be stored or transmitted, your computing cluster is just a pile of scrap metal.

Behind this rally is the market finally acknowledging:

HBM (High Bandwidth Memory) is the tightest wall choking AI development.

Micron is rising the most aggressively because it is a core supplier of HBM3E.

How tight is the supply of this product now?

NVIDIA’s GPUs are waiting to be used, orders are full, and profit margins are soaring.

If next week’s Micron earnings guidance for HBM again exceeds expectations, this show is just getting started.

It’s not over yet.

Besides AI storage demand, there is a bigger fundamental factor:

The entire storage industry, from smartphones to PCs, from enterprise to consumer, after two years of fierce destocking, finally bottomed out, and prices are starting to rise.

For asset-heavy companies like Western Digital and Seagate, once they enter a price-increase cycle, profit elasticity can be astonishing.

This is not just storytelling; it’s the hard logic of cyclical stocks.

Today, Qualcomm and ARM also moved.

This indicates that funds are starting to shift their focus from cloud AI to the devices in our hands.

AI PCs and AI smartphones are coming.

Once the upgrade cycle of terminal devices kicks off, Qualcomm and ARM will be the most immediate beneficiaries.

This potential is even greater than just speculating on data centers.

So, to sum up:

Today’s collective rally is essentially driven by two simultaneous logical resonances: “storage cycle reversal” and “explosive growth in AI storage demand.”

This is not just a simple follow-the-leader rally; big funds are using real money to redefine the second half of AI investment:

From computing power to storage capacity;

From the cloud to the terminal.
