What is PEG Ratio?

The PEG ratio represents the price-earnings-to-growth ratio, which measures how the stock is valued against its earnings growth. Unlike the price-earning ratio, which is the company’s earnings per share, the PEG ratio also considers future growth to determine if the stock is worth more or less than its stated price. Since the PEG ratio emphasises growth, it provides a relative basis for analysing companies with varying growth levels. It is stated that any PEG value that is less than 1 implies that the stock is undervalued relative to its expected growth. Read on to learn more on what is PEG ratio is, how is it calculated, its advantages, disadvantages and more in detail. 

Example of PEG Ratio

PEG ratio, meaning in finance, refers to the use of the Price Earnings to Growth (PEG) ratio. It is a financial metric to check a stock's worth by comparing the Price to Earnings (P/E) ratio to its earnings growth rate. The PEG ratio formula is: 

PEG = P/E Ratio ÷ Earnings Growth Rate

Let’s consider a stock with a P/E ratio of 30 and an expected earnings growth rate of 15%. So the PEG ratio will be:

PEG = 30 ÷ 15 = 2.

A PEG ratio value of 2 suggests that the stock is priced at two times its expected growth rate.

What is Considered to be a Good PEG Ratio?

A good PEG ratio is typically considered to be below 1. This indicates that the stock is undervalued as compared to its expected growth. The future earnings are not reflected fully by the stock price. If the PEG ratio is above 1, then it indicates that the stock is overvalued.

How to Calculate the PEG Ratio?

After understanding what is PEG ratio, let’s understand how to calculate PEG ratio. You can calculate the PEG ratio in a few simple steps, as mentioned below.

  1. Find the P/E Ratio: To calculate the PEG ratio, we need to first find the P/E ratio. The formula of the P/E ratio is Current Stock Price ÷ Earnings per Share (EPS).
  2. Determine the Earnings Growth Rate: In this step, we have to calculate the company's yearly EPS growth rate. You can obtain EPS growth rates from past financial reports or projections from analysts. The growth rate indicates the pace at which the company's earnings are increasing each year.
  3. Apply the PEG Ratio Formula: Lastly, you have to apply the PEG ratio formula, which is PEG Ratio = P/E Ratio ÷ Annual Earnings Growth Rate

What Does the PEG Ratio Tell You?

Valuable insights are provided by the PEG ratio in the stock market. Let’s take a closer look at them. 

  • A low P/E ratio might suggest that a stock can be a suitable investment option. However, incorporating the growth rate through the PEG ratio can offer a more accurate picture.
  • In general, a lower PEG ratio indicates that perhaps the stock is relatively undervalued based on its future earnings potential.
  • Considering a company's growth rate reflects companies with high P/E ratios but strong growth prospects.
  • The interpretation of the PEG ratio varies from industry to industry and depends on the type of company.
  • Many investors consider a PEG ratio below 1 as ideal, suggesting an undervalued stock.
  • A PEG ratio of 1.0 represents the fair value of a security.
  • A PEG ratio above 1.0 suggests overvaluation, while a ratio below 1.0 points to potential undervaluation.

Advantages and Disadvantages of the PEG Ratio

The following are the advantages and disadvantages of the PEG ratio.

Advantages of the PEG Ratio

Disadvantages of the PEG Ratio

Considers both price and expected earnings growth, providing a more balanced valuation than the P/E ratio alone.Heavily dependent on accurate growth estimates, which can be speculative.
It can be applied to any industry and is thus a cross-industry metric.Does not work well for companies that have earnings with volatile or cyclical patterns.
PEG ratios easily compare companies within the same industry. It does not consider qualitative elements like the quality of management or market conditions.
This is particularly useful in the evaluation of rapidly growing companies where the P/E ratio may not be a reliable indicator.It can be misleading when the expectations of growth are too optimistic or inaccurate.

Conclusion
Price-to-earnings ratios and the predicted earnings growth are compared to determine a stock's valuation using the PEG ratio. Investors should be aware of the PEG ratio since it allows them to assess if a given stock is overpriced or undervalued. The PEG ratio is highly dependent on the accuracy of the growth estimates of a company. Yet, it is a useful metric for spotting potential investment opportunities in the stock market.
