What is the PEG ratio and how is it used?

By PriyaSahu

       The PEG ratio is a tool investors use to check if a stock’s price is fair compared to its earnings growth. It combines the Price to Earnings (P/E) ratio with the company’s expected growth rate. This helps you understand if a stock is cheap, expensive, or fairly valued based on how fast the company is expected to grow. The PEG ratio helps in making better investment decisions by looking beyond just the P/E number.



What is the PEG Ratio?

PEG stands for Price/Earnings to Growth ratio. It is calculated by dividing the P/E ratio by the expected annual earnings growth rate of the company, usually in percentage. This ratio tells you how much you are paying for each unit of growth. A PEG ratio below 1 often means the stock could be undervalued, while a PEG above 1.5 might indicate overvaluation.



How to Calculate the PEG Ratio?

To calculate PEG, first find the P/E ratio by dividing the current stock price by the earnings per share (EPS). Then divide this P/E by the company’s expected growth rate. For example, if a stock has a P/E of 20 and expected growth of 25%, the PEG = 20 ÷ 25 = 0.8. This means you are paying less than 1 times the growth, which could be a good investment.



How Do Investors Use the PEG Ratio?

Investors use the PEG ratio to find stocks that have strong growth but are not overpriced. Unlike the P/E ratio alone, PEG considers how fast earnings grow, giving a better idea of value. A PEG below 1 usually means the stock might be undervalued. Investors look for these stocks to get good returns over time.

For example, two companies might have the same P/E ratio, but the one with a higher growth rate and lower PEG is often a better choice.



Benefits of Using PEG Ratio

The PEG ratio helps you avoid paying too much for stocks that grow slowly. It also helps spot stocks that are growing fast but still priced fairly. PEG is a better measure than P/E alone because it includes growth, which is very important for long-term investors. It is especially useful for industries like technology, where growth rates are higher.



Limitations of the PEG Ratio

The PEG ratio depends on future growth estimates which may not always be accurate. If growth is overestimated, PEG might give a wrong signal. Also, PEG does not consider company debts, cash flow, or risks. So, it should be used along with other financial tools and research to make smart decisions.



Where to Find PEG Ratio Information?

You can find PEG ratio data on financial websites like Moneycontrol, NSE India, or brokerage platforms. Many stock market apps in India also show PEG ratios along with other stock details. It is good to check growth estimates from multiple sources and keep updated with company news for best decisions.
