🔴 The bad news: I was no longer confident in my ability to detect a moat.

Here's why that's so important👇Image

How expensive is $NVDA really?

🟢 Price / Free Cash Flow (forward): 52

Those aren't obscene, but they are one of many data points. Image

April 6th

I said: " $TSLA is cheap!"

It's up 37% in the last week alone!

Is it still cheap?

My answer⤵️ First, we need to take into consideration that free cash flow is plunging.

Inventory is up (a very bad sign for a vertically integrated company)

And spending on AI has been huge. Image

📊 $TSLA valuation: Is the 65% dip a buying opportunity?

What today's price assumes about the future⤵️ Most only look at traditional ratios and say:

"This is WAY too expensive."

🔴 Price/Earnings (P/E): 33
🔴 Forward P/E: 59
🔴 Price/Free Cash Flow (P/FCF): 108
🔴 Forward P/FCF: 113

They aren't wrong, but it's incomplete.

What if we do a reverse DCF?⤵️

This might seem blasphemous, but I don't think $CRWD is *crazy* expensive right now.

Just *normal* expensive.

Here's why👇 Management has gone on the record saying $CRWD can reach 38% Free Cash Flow margins.

That's $0.38 of every $1.00 in sales going in the company's pocket. Image

The three cheapest stocks in The Antifragile Portfolio today, in reverse order⤵️ 3) Amazon $AMZN

Amazon is an odd beast. It can go on capex binges, then capex fasts.

I like to use Price/Operating Cash Flow (**real** cash from operations) to check valuation.
