PE Ratio (Price to Earnings Ratio) - Know in Detail| Espresso

# What is the PE Ratio in the Share Market?

When you decide to invest in the share markets, there are several choices that you need to make. The most crucial of them is selecting the right stocks for your investment. However, choosing the right stock is not as straightforward as it seems. As an investor, you need to take your decision based on several important factors.

One such factor is the price-to-earnings ratio or the PE ratio of the company. It is one of the widely used tools for conducting stock market analysis and taking investment decisions. Let us explore what is PE in the share market, its different types, and how you can use it to make your investment decisions.

## What is the PE Ratio in the Share Market?

The price-to-earnings ratio or PE ratio in the share market is the relation between a company’s current share price and its earnings per share (EPS). It reflects the amount that the investors are willing to pay for the company’s profits. As an investor, you can use the PE ratio of a company to evaluate its potential to grow in the future.

A high PE ratio means that investors are optimistic about the company’s growth in the future and are hence, willing to pay more to buy its shares. However, it also means that the company’s stocks are overvalued.

Similarly, if a company’s PE ratio is low, it means that the investors are not expecting it to grow in the future and are hence, not willing to pay a premium for buying its shares.

## How to Calculate the PE ratio of a Company?

The PE ratio of a stock or company can be calculated by simply dividing the current market price of a single stock by the company’s earnings per share. Below is the formula for calculating the PE ratio of a stock:

P/E Ratio = Current market price of the share / Earnings per share

As you can see, the P/E ratio signifies how much the investors are willing to invest in a company’s share against ₹1 of its earnings. So, for instance, if the PE ratio of a company is 10, it simply means that the investors are willing to spend ₹10 on a company’s share against ₹1 of its profits.

Quite understandably, in case a company is not making any profits or facing losses, the PE ratio would be negative.

## Types of PE ratio

Now that we have discussed what is PE ratio in the share market, let’s have a look at its types:

• Forward PE ratio

The forward PE ratio is calculated by dividing the current market price of a share by the estimated EPS of the company over the next 12 months. Since the forward PE ratio is based on the estimations of the future earnings of a company, it is also called the estimated PE ratio.

You can use the forward PE ratio to assess how a company can perform in the future and what can be its estimated growth rate. Calculating the forward PE ratio requires expert guidance since it involves estimations and forecasts of a company’s EPS.

• Trailing PE ratio

The trailing PE ratio is calculated in an opposite way to that of the forward PE ratio. It is done by dividing the current market price of a stock by the EPS of the company over the past 12 months. The trailing PE ratio gives a more accurate view of a company’s performance since it involves past data and not future estimations.

You can use the trailing PE ratio to know how a company has performed in the past year and then decide whether to invest in its shares or not. The calculation of the trailing PE ratio is easier since every listed company declares its financial results every quarter.

## How to Use the PE Ratio for Making Investment Decisions?

The PE ratio helps you know the past performance of a company and get an estimation of its future growth. You can make your investment decisions based on your understanding and estimations. Here’s what the PE ratio of a company signifies:

• A high PE ratio

Generally, a company with a high PE ratio is a good pick for investment as investors are estimating it to grow in the future. That is why they are willing to pay more for its shares. However, a high PE ratio also indicates that a company’s stocks are overvalued, and hence, their prices may fall in the future.

• A low PE ratio

Stocks of companies with a low price-to-earnings ratio are considered undervalued. It can be an indication of weak past performance or future estimations. However, if the fundamentals of a company are strong, you can invest in its shares even if it has a low PE ratio.
