This 1 Stock Proves It: The AI Trade is Not Over.

Here's a statistic that doesn't make intuitive sense:

A note from our sponsors...

Micron Technology (NASDAQ: MU) is up over 700% in the past year … 

… But the stock has only gotten cheaper.

Not cheaper in the "the stock pulled back" sense. Cheaper in the fundamental sense: earnings projections have accelerated so far beyond even the dramatic price appreciation that the forward valuation has actually contracted. That's not a setup you see often, and it's exactly the kind of gap our Zen Ratings system is built to find.

MU is our highest-rated semiconductor stock. Here's why the trade isn't over.

Why Memory Is Different This Cycle

Every previous memory semiconductor upcycle was purely cyclical. Supply and demand for PCs, smartphones, servers … the cycle runs hot, oversupply hits, the stocks crater, repeat.

But this cycle has something different layered underneath it, and understanding this part could be your edge as the next phase unfolds…

High Bandwidth Memory, or HBM, is required by every serious AI accelerator being built right now. Nvidia's Blackwell chips need it. Every next-generation data center GPU needs it. The entire AI infrastructure buildout is physically dependent on it.

And only three companies in the world can produce HBM at scale. Micron is one of them.

The HBM market is completely sold out through 2026, with major cloud providers receiving significantly less supply than requested, and Micron's Cloud Memory Business Unit is already achieving approximately 66% gross margins.

That's a structural position in the AI infrastructure stack that didn't exist in previous upcycles.

The Valuation Paradox

Here's the number that matters most right now.

MU trades at a forward P/E of roughly 9 to 11x, versus the semiconductor industry average of 31x. A stock in the top tier of its industry, growing faster than virtually any peer, trading at roughly a third of the sector multiple.

The PEG ratio sits at just 0.3, which is one of the lowest readings in the entire semiconductor space. That number reflects a business where earnings are growing so much faster than the stock price that traditional valuation metrics struggle to capture it.

Net income is forecast to grow 251% next year versus 38% growth forecast for the broader semiconductor industry. The market is applying a cyclical discount to a business that increasingly has a structural growth engine underneath it.

The Triple-A That Matters

Our Zen Ratings system gives MU an A overall. It’s our highest-rated semiconductor name.

The Component Grade profile is unusual. As in Growth, Momentum, and Financials simultaneously is a combination that's hard to find. 

• A in Growth means the revenue acceleration is real and already showing up across 22 different metrics. 
• A in Momentum means the market is actively pricing it in — this isn't a contrarian bet waiting for discovery (a quick look at the stock chart over the past year could tell you that). 
• A in Financials means the balance sheet is clean enough to sustain the investment cycle without diluting shareholders. Return on equity sits at 39.82% and return on invested capital at 37.40%.

But the B in Value is perhaps the most interesting grade of all, in my opinion. It reflects what the grades always reflect for a stock in the middle of an earnings acceleration: the trailing metrics haven't caught up to the forward picture yet. On a forward basis the valuation is still anything but stretched. On that note, most “value investors” are doing it all wrong, and will always miss stocks like this … here’s why. 

The One Caveat

The D rating in Safety is real and worth naming directly.

Memory semiconductors are among the most volatile stocks in the market. When the cycle turns, it turns hard, its high beta means that MU moves roughly twice as much as the broader market in both directions. This is not a defensive position. It's a high-conviction growth bet that requires understanding what you own and sizing accordingly.

There’s one other component grade where MU also scores a D. Click here to see its full Component Grade breakdown. 

Another point to watch: Micron reports Q3 2026 earnings on June 24. Two consecutive quarters of guidance raises have reset expectations significantly higher. If HBM demand continues to outrun supply and margin expansion holds, the forward multiple could compress further even as the stock moves higher.

Bottom Line

The memory trade has evolved. What started as a cyclical recovery has developed a structural AI foundation that makes this cycle different from the ones before it. MU is our highest-rated semiconductor name … up 700% in a year, somehow still trading at 9 to 11x forward earnings, with the fastest earnings growth in its sector and HBM supply sold out through the end of the year.

The trade likely isn't over.
