Price vs. Value: The Philosopy of Valuation
Understand the fundamental difference between what you pay (price) and what you get (value), and why valuation is more art than science.
Learning Objectives
- Distinguish between market price and intrinsic value
- Understand the role of bias and uncertainty in valuation
- Learn why every number in a model needs a narrative
- Recognize that valuation is subjective
Price vs. Value#
"Price is what you pay. Value is what you get." – Warren Buffett
This famous quote encapsulates the heart of investing. In the stock market, you see a price every second. But that price changes constantly based on news, sentiment, and liquidity. Does the value of the business change every second? Of course not.
The Core Distinction#
| Concept | Definition | What Drives It |
|---|---|---|
| Price | The amount you pay to buy a share | Supply, demand, mood, momentum, liquidity |
| Value | The true worth of the business's future cash flows | Earnings, cash flow, growth, risk, assets |
Example: The House in a Storm#
Imagine you buy a rental property for $500,000. It generates $30,000 a year in rent.
- Scenario: A massive thunderstorm hits the town. Panic ensues. Nobody wants to buy real estate today. The highest offer you get is $400,000.
- The Price: Has dropped 20% to $400,000 because of fear/sentiment.
- The Value: Did the storm destroy the house? No. Did tenants stop paying rent? No. The house still generates $30,000/year. The intrinsic value remains $500,000.
As an investor, your goal is to buy the house when the storm hits (Price < Value).
The Three Truths of Valuation#
Professor Aswath Damodaran, often called the "Dean of Valuation," emphasizes three critical truths that every investor must accept:
1. All Valuations are Biased#
You cannot value a company in a vacuum. If you like the CEO, use their products, or read positive news, you subconsciously adjust your inputs (like growth rates) to get a higher value.
- The solution: Be honest about your bias. Ask yourself, "Why do I want to value this company?" and "What if I'm wrong?"
2. Most Valuations are Wrong#
The future is uncertain. You are forecasting cash flows for 5 or 10 years into the future. You will be wrong.
- The solution: Don't aim for a precise number (e.g., "$124.32"). Aim for a range (e.g., "$110 to $140"). Valuation provides an estimate, not a fact.
3. Simpler is Often Better#
Complex models with thousands of inputs create a false sense of precision. If you have to estimate 100 variables, you have 100 chances to make a mistake.
- The solution: Focus on the big drivers: Revenue growth, margins, and risk.
Numbers vs. Narrative#
A spreadsheet is just a tool. A good valuation connects numbers to a story.
- All Story, No Numbers: "This company will change the world!" (But how will they make money? When?)
- All Numbers, No Story: "They will grow 20% forever." (Why? What competitive advantage allows that?)
Example: Valuing a Ride-Sharing Company#
- Bad Valuation: Plugging random growth rates into Excel until the price looks right.
- Good Valuation (Narrative + Numbers):
- Narrative: "Ride-sharing will replace 2nd car ownership for urban millennials because it is cheaper and more convenient."
- Numbers: "Total Addressable Market is $X billion. The company can capture 20% market share. Operating margins will improve to 15% as they stop subsidizing rides."
Key Takeaways
- Price is market sentiment; Value is intrinsic worth based on fundamentals.
- Think of the "House in a Storm": Price changes with mood, Value changes with cash flow.
- Valuation is subjective and prone to bias—admit it and adjust.
- Precision is an illusion; value is a range, not a single point.
- Combine quantitative models with a qualitative narrative for the best results.
