You just started learning the up and down world of stock market. You just learned the simple concept of buying and selling stocks to earn extra money in this field. And now, your question is, how do you pick stocks among the 300+ listed companies?! Too many choices. isn’t it?! There are several ways of picking a right stock, one of these is by using an indicator. And one of the famous indicator used in valuing a company is Price to Earnings Ratio or simply P/E Ratio.

Read along! In this tsupitero blog, we will define and discuss how to use P/E Ratio in creating choices for you.


What is P/E Ratio

The price-earnings ratio (P/E Ratio) is the ratio for valuing a company that measures its current market value per share relative to its earnings per-share. The formula for calculating P/E Ratio is:

P/E Ratio = Market Value Per Share / Earnings Per Share

Malabo pa rin ano? Ganito lang yan. Halimbawa, ikaw ay kasalukuyang nag-iisip kung alin sa dalawang kumpanya ang iyong bibilihin. At ang nagpahirap pa sa sitwasyon ay nang iyong nalaman na ang dalawang kumpanya na ito ay:

  •  Parehas na nasa category ng “property”.
  • Akalain mo yun! Aba’y parehas din pala ang halaga ng kinita nila sa nakaraang taon (Earnings Per Share).
  • Ang kaibahan lamang nilang dalawa ay ang current market value per share nito.
Company A Company B
Category Property Property
Earnings Per Share Php 5.00 per share Php 5.00 per share
Current Market Value Php 50.00 per share Php 80.00 per share
Calculated P/E Ratio 10.00 16.00

Table 1. Shows the comparison between the two companies using the parameters for calculating P/E Ratio.


How to use P/E Ratio

In terms of earnings, both the Company A and B are earning Php 5.00 per share. However, we can buy company A at a market price of Php 50.00, a much lower price in comparison with Company B at Php 80.00! So, why would I buy company B if there is another company that can generate the same amount of earnings but can be bought at a much lower price? Notice that the P/E Ratio for company A is lower than company B, because company A has a lower market value(Php 50.00).

There are many reasons why a company has a lower market value compared to others which is dependent on how the market participants perceive the company. P/E Ratio also suggests if a company is undervalued based on its earnings and current market value. And this is just one way of analyzing a stock.

Unfortunately, the same with other indicators, P/E ratio alone cannot be used in choosing your beloved stock. A better decision is derived from a combination of different indicators.

Because the market value is changing every day, therefore, the P/E Ratio also changes every day. The lower the P/E Ratio is, the more undervalue a company is.
