What is PEG?

PEG, or Price/Earnings-to-Growth ratio, compares a company’s P/E ratio to its expected earnings growth rate. It is used to assess whether a stock is fairly valued, overvalued, or undervalued considering its growth prospects.

How do you interpret PEG?

PEG (Price/Earnings to Growth) ratio adjusts the P/E ratio by the company’s earnings growth rate, providing a more nuanced view of whether a stock is overvalued or undervalued considering its growth potential.

How to Calculate PEG?

To calculate the PEG ratio, divide the Price-to-Earnings (P/E) ratio by the company’s earnings growth rate.

PEG = (Price/Earnings) / Annual Earnings Growth Rate

where

• Price/Earnings: The P/E ratio, or the stock price divided by earnings per share.
• Annual Earnings Growth Rate: The projected annual rate of growth in earnings.

Why is PEG important?

PEG is important because it adjusts the P/E ratio to account for expected growth. While P/E alone only looks at current earnings, PEG incorporates future growth, providing a more comprehensive view of the stock's valuation. It helps investors identify companies that may be undervalued when growth potential is factored in.

How does PEG benefit investors?

The PEG ratio benefits investors by combining current valuation (via the P/E ratio) with future growth expectations. It helps investors assess whether a high P/E ratio is justified by strong future growth, or whether a low P/E might be hiding a company with poor growth prospects. The PEG ratio is especially useful for comparing companies within the same industry that have different growth rates.

Using PEG to Evaluate Stock Performance

PEG is often used to evaluate whether a company’s stock is overvalued or undervalued relative to its growth potential. A low PEG ratio suggests that a stock is undervalued given its growth prospects, while a high PEG ratio could indicate that a stock’s price has outrun its growth potential.

FAQ about PEG

What is a Good PEG?

A PEG ratio below 1 is typically considered attractive, as it indicates that the stock is undervalued relative to its growth potential. A PEG of 1 generally signals that the stock is fairly valued. However, industry-specific norms should be considered.

What Is the Difference Between Metric 1 and Metric 2?

The P/E ratio looks at a company’s valuation relative to its current earnings, while the PEG ratio adjusts the P/E ratio to account for expected future earnings growth. PEG provides a more forward-looking view of the stock’s value.

Is it bad to have a negative PEG?

A high PEG ratio (greater than 1) could indicate that a stock is overvalued relative to its growth potential. However, if the company’s future growth is expected to be robust, a higher PEG ratio might be justified.

What Causes PEG to Increase?

The PEG ratio increases when either the P/E ratio rises or the expected earnings growth rate decreases. This could signal that a company’s stock price has risen without a corresponding increase in earnings growth potential.

What are the Limitations of PEG?

The PEG ratio assumes that earnings growth rates are accurate and constant over time, which may not always be true. It also doesn’t account for other factors like cash flow or balance sheet strength, and it may be less useful for cyclical companies with volatile earnings growth.

When should I not use PEG?

PEG may not be appropriate for evaluating companies with highly volatile or unpredictable earnings growth, such as startups or cyclical businesses. It is also less useful in industries where growth expectations are uncertain.

How does PEG compare across industries?

PEG ratios vary across industries based on expected growth rates. For example, technology and healthcare companies often have higher PEG ratios due to strong growth prospects, while utilities or consumer staples tend to have lower PEG ratios because of slower growth expectations. It’s important to compare PEG ratios within the same industry for meaningful analysis.
