# 🔥💾 David Tepper is betting on $Micron Tech(MU.US). This is not a short-term trade, but a heavy bet

🔥💾 David Tepper is betting on $Micron Tech(MU.US). This is not a short-term trade, but a heavy bet on the supply side of AI.

While many are still discussing the valuation recovery of software,

David Tepper has already shifted his portfolio further upstream in Q4.

According to disclosures, Appaloosa increased its $Micron Tech(MU.US) position by 200%,

bringing the size to approximately $428 million,

making it one of the top four largest holdings.

This is not a test.

This is a structural increase.

At the same time, he also established a new $ISHRS MSCI S Korea Capped(EWY.US) position,

indirectly betting on Samsung and SK Hynix.

The logic is clear—

If AI is the wave,

the real bottleneck is in memory.

Model training, inference, and increasing server density,

HBM and DRAM are hard constraints.

When supply is constrained and demand explodes,

price elasticity is far higher than software.

This is also why the memory chain has seen "independent performance" this year,

while software is under pressure.

The market is starting to reprice—

In the AI era,

"computing infrastructure" takes priority over "application narratives."

What I see is not simple rotation.

It's capital restructuring the profit distribution within the AI industry.

In the past two years,

profits were concentrated in $NVIDIA(NVDA.US).

Now, capital is starting to spread to memory, equipment, and materials.

Tepper's portfolio adjustment signals one thing:

If you want to participate in AI,

prioritize embracing the certainty of the supply side.

Not the story.

But there is a key variable here—

Will the memory cycle reverse as quickly as it has historically?

If supply is released within 12–18 months,

the profit peak may come earlier.

If structural shortages persist,

then it's not a cycle, but a new platform.

What I'm more concerned about is:

Is this chasing the rally at the top of the cycle,

or confirmation of the early stage of a supercycle?
