The Pitfalls of the PEG Ratio
Introduction
The Price/Earnings to Growth (PEG) ratio is often used in stock valuation, combining a company's P/E ratio with its earnings growth rate. Many analysts believe a stock is fairly valued when its PEG ratio is one. For instance, if a stock has a P/E of 10 and a growth rate of 10%, it's often deemed fairly valued. However, this simplistic approach is misleading. Let's explore why.
The Misleading Simplicity
You've likely encountered claims that equate a stock's fair value to a PEG ratio of one. At first glance, this sounds reasonable. If a stock grows at 8%, its fair P/E should be 8. A 5% growth? A P/E of 5. But what about a company with 0% growth? According to the PEG logic, it should have a P/E of 0, making it worthless. Clearly, this doesn't make sense.
For further insights into common misunderstandings about the PEG ratio, you can consult sources like [MoneyChimp](http://www.moneychimp.com/glossary/peg_ratio.htm), [The Motley Fool](http://www.fool.com/School/TheFoolRatio.htm), and [Investopedia](http://www.investopedia.com/articles/analyst/043002.asp).
A More Sensible Approach
For companies with 0% growth, their fair P/E ratio shouldn't be zero. Rather, it should be slightly above a risk-free interest rate, like a 10-year treasury bond. If such a bond yields 4.6%, the stock should offer a 7.6% yield. This implies a P/E ratio of about 13.2.
The Flaws of Infinite Growth Assumptions
The PEG ratio also assumes perpetual growth, which is unrealistic. For example, if a company grows at 10% for five years but then slows to 2%, the PEG ratio doesn’t account for this change. Therefore, relying solely on the PEG ratio for fair value determination is flawed.
Conclusion
While it's logical to value stocks with higher growth rates at higher P/E ratios, using a PEG ratio of one as a universal measure of fair value is incorrect. Although there's no precise formula for calculating this, further reading on Calculating Fair Value with Growth and Fair Value with Negative Growth can provide deeper insights.
By understanding these nuances, investors can make more informed decisions rather than relying on oversimplified metrics.
