Valuation isn't a mysterious art reserved for Wall Street analysts — it's a learnable discipline, and this book teaches you the actual mechanics of figuring out what something is worth.

The short version: a quick read to help you decide. Not a replacement for the book.
Most investing books tell you what to look for. This one teaches you how to calculate it yourself.
Every asset has an intrinsic value based on its cash flows, growth, and risk — and that value can be estimated, even if never known with certainty.
1. All valuation is about cash flows, growth, and risk.
Every model is really just an argument about these three things.
2. Discounted cash flow is a story, told in numbers.
The value of the exercise is often in the discipline of the assumptions.
3. Relative valuation (multiples) is a shortcut — know its blind spots.
It assumes the market has priced the comparison group correctly.
4. Growth is expensive to buy and easy to overpay for.
The market routinely overestimates how long high growth can persist.
5. Uncertainty is not a reason to skip valuation — it's a reason to do it with ranges.
A wrong point estimate is worse than an honest range.
Anyone who wants to move beyond "this stock feels expensive/cheap" and actually build a number to test that feeling against.
