Don’t Let Valuation Models Fool You: Think Like a Business Owner
#Issue 27 The One Question That Matters More Than Any Financial Model
Most people think investing is all about complex valuation models—DCF, terminal value, WACC, and so on. But the truth is, these are just tools. And tools are only useful if you know how and when to use them.
In reality, the most powerful valuation tool is common sense.
Ask yourself a simple question:
“Would I be happy to buy this entire business and own it for the rest of my life at this price?”
If the answer is yes, then you’re valuing the business the right way—like an owner, not an analyst.
When you think like an owner, you don’t get distracted by fancy formulas. You try to understand the business deeply:
Where does the money come from?
How predictable are the profits?
Does it need a lot of money to grow?
Is that money needed once or again and again?
Without understanding the business, no model will help you. You’ll just keep changing numbers and getting different results. One day your model says it’s undervalued, the next day it looks expensive—and all because you changed a few assumptions.
Why Simple Thinking Wins
Here’s something powerful: if someone doesn’t know how to use a complex model like DCF, they might actually have an advantage. Why? Because they can’t fool themselves with numbers.
If you know DCF too well, you might end up twisting the numbers to justify what you already want to believe. That’s dangerous. As the quote says:
“The last level of deceit in life is deluding yourself.”
Once you start lying to yourself, there’s no going back.
Final Thought
You don’t need to be a finance expert to value a business well. You just need to understand the business clearly and think long-term. Keep it simple. Don’t play games with numbers. Don’t trick yourself.
And always ask:
“Would I buy the whole business at this price?”
If the answer is yes, you’re on the right track.
Happy Weekend!
With Love,
