Why Do We Always Find Great Stocks After They Take Off?

What $CRDO and $UBER taught me about spotting change before the story becomes obvious.
October 2026 Β· ~4 min read
The familiar feeling
THE STOCK IS ALREADY UP 100%.
Your first thought:
β€œI missed it.”
But did you miss the stock β€” or the change happening inside the business?
01 Β· CRDO

I followed AI one layer deeper.

AI was already obvious. Nvidia was already obvious. So instead of asking β€œwhat's the next Nvidia?” I started asking a different question:

What becomes more important if all this AI compute keeps growing?

CRDO

That is what made Credo interesting to me. But the story only mattered if the numbers started confirming it.

FY24 REVENUE$193M
FY25 REVENUE$437M
FY26 REVENUE$1.3B

AEC became a major growth engine. The question I care about now is what comes after it: optics, SerDes, DSP, PCIe, silicon photonics and potentially a broader AI-connectivity platform.

Is AEC the destination β€” or Credo's entry point into something much bigger?
What CRDO taught meSometimes the opportunity isn't the obvious winner. It's what becomes more important because the obvious winner succeeds.
02 Β· UBER

Everyone knew Uber. That wasn't the opportunity.

Millions of people already knew the product. The interesting question was whether Uber could turn its enormous platform into a profitable, cash-generating business.

Better Economics

Free Cash Flow

Profitable Growth

The product didn't suddenly change. The economics did. That made the business look fundamentally different.

What UBER taught meYou don't always need to discover an unknown company. Sometimes the opportunity is recognizing when a familiar company becomes a much better business.

Then it clicked.

Two completely different stocks. Same signal: something changed, and the numbers started proving it.

My framework

The 5 questions I ask now.

01WHAT CHANGED?Why is the business different today?
02CAN I SEE IT?Revenue Β· margins Β· FCF Β· customers.
03HOW BIG?Products Β· markets Β· operating leverage.
04WHAT BREAKS IT?Competition Β· execution Β· technology.
05WHAT'S PRICED IN?Great company β‰  great price.

I don't need a 30-point checklist. I want to understand what changed, whether it's real, how large the opportunity could become, what could make me wrong, and how much success the market already expects.

Being β€œlate”

Earlier doesn't automatically mean better.

$10Very little evidence
$20The inflection starts appearing
$40The business begins proving itself

You may pay a higher price later, but you may also have substantially more information. That doesn't make $40 attractive by itself β€” it means β€œthe stock already went up” isn't enough to decide whether the opportunity is over.

Did I miss the stock?

How much of the opportunity is still ahead?

CHANGE β†’ EVIDENCE β†’ OPPORTUNITY β†’ RISK β†’ PRICE
I'll still miss plenty of winners. I'm not trying to catch every stock before it moves. I'm looking for businesses where something important is changing, the numbers are beginning to prove it, and a meaningful part of the opportunity may still be ahead.

Credo reinforced that for me. Uber showed me the same pattern from a completely different direction. Now I'm looking for the next one.
