The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We'll look at Tai Sin Electric Limited's (SGX:500) P/E ratio and reflect on what it tells us about the company's share price. What is Tai Sin Electric's P/E ratio? Well, based on the last twelve months it is 10.65. In other words, at today's prices, investors are paying SGD10.65 for every SGD1 in prior year profit.

### How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price Ã· Earnings per Share (EPS)

Or for Tai Sin Electric:

P/E of 10.65 = SGD0.33 Ã· SGD0.031 (Based on the trailing twelve months to March 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each SGD1 of company earnings. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does Tai Sin Electric Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. You can see in the image below that the average P/E (11.3) for companies in the electrical industry is roughly the same as Tai Sin Electric's P/E.

Tai Sin Electric's P/E tells us that market participants think its prospects are roughly in line with its industry. So if Tai Sin Electric actually outperforms its peers going forward, that should be a positive for the share price. I would further inform my view by checking insider buying and selling., among other things.

### How Growth Rates Impact P/E Ratios

When earnings fall, the 'E' decreases, over time. That means unless the share price falls, the P/E will increase in a few years. So while a stock may look cheap based on past earnings, it could be expensive based on future earnings.

Most would be impressed by Tai Sin Electric earnings growth of 11% in the last year. But earnings per share are down 11% per year over the last five years.

### Remember: P/E Ratios Don't Consider The Balance Sheet

Don't forget that the P/E ratio considers market capitalization. That means it doesn't take debt or cash into account. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

### Tai Sin Electric's Balance Sheet

Net debt totals just 1.3% of Tai Sin Electric's market cap. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

### The Verdict On Tai Sin Electric's P/E Ratio

Tai Sin Electric's P/E is 10.7 which is below average (13) in the SG market. The company does have a little debt, and EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified.

When the market is wrong about a stock, it gives savvy investors an opportunity. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
