Micron (MU) is booming, and it still doesn't look ‘expensive’ based on next year's earnings. So why does our own valuation say it could be worth 40% less?

📉 Boom-time math: Our discounted cash flow valuation puts Micron's fair value near US$565.
🎥 Straight from the founder: Al Bentley explains why a company's value is really all its future cash flows, brought back to today.
☀️ More than hot air: Why the summer's most obvious demand story comes with a catch.

A stock is worth every dollar of cash the company will ever produce, added up and discounted back to today. Not this year's profit at some arbitrary earnings multiple. 

Micron (MU) makes the point beautifully. AI has its memory chips sold out and it's throwing off record cash, and even after a huge run it trades at only about 7 times next year’s projected earnings, which hardly screams expensive. 

But run the cash flows forward and it shifts. Our discounted cash flow model, using analyst estimates, expects Micron's free cash flow to decline in the out-years, the way memory cycles have always eventually turned. Discounting those further out years of cash results in a fair value near US$565, well under the recent US$950 price. Same company, but two different answers, because one looks at the next year and the other considers every year. 

What's a boom you're happy to own because you think it's here to stay?
