Micron’s Earnings Were Incredible - But Are AI/Semiconductor Expectations Becoming Dangerous?

We may be witnessing one of the craziest bull runs of our lifetime, but this past week was a good reminder that even in a bull market, things can get shaky fast.

Nasdaq was down around 5% for the week and the S&P was down around 2%, so clearly it wasn’t a great week. I don’t think there was one single reason for it either. There were a few things happening at the same time, and honestly some of the price action didn’t make perfect sense to me.

Before getting into Micron, I think the broader setup matters.

First, there was still geopolitical noise in the background. Last week it looked like tensions in the Middle East were cooling down after the ceasefire news, but then we still had reports of smaller attacks around the Strait of Hormuz and some U.S. retaliation headlines.

I don’t think the market really cares about every single war headline at this point though. To me, the two things that matter more are oil and the 10-year yield.

If oil keeps cooling down and the 10-year stays under control, I think the market can mostly ignore the geopolitical stuff. Lower oil helps the inflation story, and lower yields obviously help growth/tech names.

So even though the war headlines were there, I don’t think that was the main reason the market struggled this week.

The bigger event was Micron.

Micron is right in the middle of the AI trade because of memory, DRAM, HBM, and data center demand. So this report wasn’t just about Micron. It was basically a read-through for the whole AI semiconductor supply chain.

And the numbers were ridiculous.

Q3 Results

|Metric|Consensus Estimate|Actual Reported|Beat|

|:-|:-|:-|:-|

|Revenue|$35.69B|$41.46B|\+16.17%|

|Adjusted EPS|$20.49|$25.11|\+22.55%|

Those are monster numbers, but honestly I wasn’t even that focused on the previous quarter. I already expected them to beat. I figured they would easily clear the $35.7B revenue estimate and the roughly $20.5 EPS estimate.

What I cared about was guidance.

That’s what Wall Street really cares about anyway. Not just what happened last quarter, but whether the company can keep growing.

And this is where the report got really interesting.

Q4 Guidance

|Metric|Wall Street Expectations|Micron Guidance|

|:-|:-|:-|

|Revenue|\~$43B|$49B–$51B|

|Adjusted EPS|\~$25|$30–$32|

|Gross Margin|\~81.8%|\~86%|

That’s a huge beat-and-raise.

Going into the report, this was basically how I was thinking about it:

If Micron guided EPS at $25 or below, I was probably going to seriously consider selling my semi positions.

If they guided above $25 but below $27, I was still probably going to start reducing exposure.

If they guided above $27, I would keep holding, but keep watching the rest of the AI/semi narrative very closely.

Then they guided around $31.

So yeah, that changed things.

The earnings are clearly strong. AI demand is clearly turning into real revenue, real margins, and real earnings power. I don’t think anyone can deny that.

But here’s where I get more cautious.

The problem is no longer whether Micron is doing well. They obviously are.

The problem is expectations.

Micron’s EPS trajectory has been insane. It went from around $5 toward the end of last year, then around $12, then $25, and now they’re guiding around $31.

That’s amazing, but it also creates a problem. Once a company keeps crushing expectations, the market starts expecting them to keep crushing expectations.

At this point, just hitting $31 might not even be enough. If investors are now expecting another 20% upside surprise, then Micron may need something closer to $37 EPS next quarter just to keep the same momentum going.

Then after that, the next quarter’s guidance would probably need to be even higher. Maybe $40+ EPS.

That starts to get crazy.

This is where I think the risk/reward gets tricky. The stock has already had a huge move. The market might already be pricing in not just good execution, but almost perfect execution.

It feels like Micron is no longer being asked to get an A.

It’s being asked to get a 100 every quarter.

And in this market, even a 95 might not be enough.

That’s the part that gave me a reality check.

I’m not saying Micron is weak. It’s not. The company is executing extremely well. But expectations are now so high that I don’t think the setup is as easy as “earnings good, stock go up.”

Another thing is Micron isn’t the only AI/semi earnings event coming up.

In July, we still have names like ASML, TSMC, Texas Instruments, Intel, Microsoft, Google, Lam Research, and others reporting.

Each one of those reports could move the AI trade.

They could confirm the bull case and send everything higher. Or they could expose cracks in demand, margins, capex, customer concentration, or how much Big Tech can realistically keep spending on AI infrastructure.

That’s really my bigger concern.

The chip companies are making insane money right now, but a lot of that money is coming from Big Tech’s AI spending. At some point, the market is going to start asking whether that level of spending is sustainable.

Great for semis in the short term, yes. But if the customers themselves start getting pressured, then the whole trade gets more complicated.

There’s also the reported OpenAI IPO delay. I don’t want to make that bigger than it is, but I do think it matters for sentiment.

If OpenAI is really considering delaying its IPO until 2027 because the valuation may not hold up in the current market, that tells me investors might be getting more selective with AI valuations.

That doesn’t mean OpenAI is in trouble. But it does make me wonder if the market is starting to become less willing to pay any price for AI growth.

And if private AI valuations start getting questioned, eventually that can bleed into public AI and semiconductor valuations too.

There were other things this week too, like inflation data, but I honestly don’t think that was the main story. The market feels more focused on AI expectations, earnings, capex, and whether the whole trade is getting stretched.

So my view is basically this:

Micron’s earnings were excellent.

The guidance was even better.

The AI demand story is still alive.

But expectations are now extremely high.

I’m still holding my semiconductor positions for now because the earnings are too strong to ignore. But I’m definitely more cautious than I was before. Over the next few months, I plan to gradually reduce some of my semiconductor exposure if the market gives me a good opportunity.

That could be into strength if the sector rallies hard again. Or it could be if I start seeing cracks in earnings or guidance.

I don’t think this is a market where I’d panic sell everything at once. The trend is still strong and there could easily be more upside.

But I also don’t think this is the time to get reckless with leverage or options. The risk is too high now.

If you’re holding semi names here, I think you have to ask yourself one question:

Would you be okay taking a 20% to 30% hit if the AI narrative turns?

Because I think that’s very possible from here.

The upside is still there, but the downside is too. To me, this is starting to look more like a 50/50 risk-reward setup.

I’m bullish on the businesses.

I’m just more cautious on the stocks.

Curious how everyone else is looking at this. Is Micron still a buy after this report, or are expectations getting too high?
