Module 7: Valuation – Price vs. Value

We know how to read the financial statements; now we must determine if the numbers on them are "cheap" or "expensive".

1. The Supermarket Analogy

Imagine you walk into a supermarket to buy toothpaste. Toothpaste A costs $2. Toothpaste B costs $15. You immediately know B is "expensive" because you have an internal anchor of what toothpaste is worth. In the stock market, the "Price" (displayed on your brokerage terminal) tells you nothing in isolation. A stock trading at $2,000 can actually be "cheaper" than a stock trading at $50. To judge true value, we need Valuation Ratios.

2. The P/E Ratio (Price-to-Earnings)

This is the most common metric in the world. P/E =

  • The Meaning: It tells you how much you are paying for $1 of corporate earnings.
  • The Context: The historical S&P 500 average P/E is roughly 15x to 18x. If the market drops below 15x (e.g., during the 2008 crash), it’s generally a systemic discount. If it crosses 25x, it’s a bubble.
  • The Trap: A low P/E isn't always good. Sometimes a company is cheap because its business model is dying (a Value Trap). Always ask: Why is this cheap?

3. The P/B Ratio (Price-to-Book)

Used primarily for valuing Banks and Financial Institutions (like JPMorgan Chase or Bank of America).

P/B =

  • The Logic: For a manufacturing factory, book value (machinery) depreciates and is hard to calculate. For a bank, the book value (money and loans) is their actual raw material.

4. PEG Ratio (Price/Earnings-to-Growth)

Developed to fix the flaws of the P/E ratio. If a tech company is growing at 50% per year, it mathematically deserves a higher P/E than a utility company growing at 2%.

PEG =

  • Peter Lynch’s Rule:
    • PEG < 1: Undervalued (Buy).
    • PEG = 1: Fairly Valued.
    • PEG > 2: Expensive.

5. Intrinsic Value & Margin of Safety

Benjamin Graham, the father of value investing, taught us that every stock has an Intrinsic Value (a True Worth). If the Intrinsic Value is $100, you should not buy it at $100. You should buy it at $70. The $30 difference is your Margin of Safety. It is your mathematical cushion against being wrong. If you buy at a discount, even if the company performs strictly "okay," you won't lose your principal.

Case Study & Self-Assessment

Case Study: Microsoft is a phenomenal, world-class business. During the late 1999 Dot-Com bubble, Microsoft's P/E ratio exceeded 60x.

  • Analysis: Valuation is the difference between a great company and a great investment. Microsoft was a great company. But buying it at a P/E of 60x meant it was a terrible investment at that specific moment. It took over a decade for the stock price to recover to its 1999 highs, despite the company growing earnings the entire time. Your job is to wait patiently until the market offers a "mismatch" price.

Quiz:

  1. Why is the P/B (Price-to-Book) ratio generally more appropriate for analyzing a commercial bank than a software company?
  2. If Company X has a P/E of 30, and its earnings are growing at 15% a year, what is its PEG ratio? Is it considered cheap or expensive according to Peter Lynch?
