# Why Singapore Technologies Engineering Ltd's (SGX:S63) High P/E Ratio Isn't Necessarily A Bad Thing

Today, we'll introduce the concept of the P/E ratio for those who are learning about investing. We'll apply a basic P/E ratio analysis to Singapore Technologies Engineering Ltd's (SGX:S63), to help you decide if the stock is worth further research. Singapore Technologies Engineering has a P/E ratio of 23.57, based on the last twelve months. That is equivalent to an earnings yield of about 4.2%.

### How Do You Calculate Singapore Technologies Engineering's P/E Ratio?

The formula for price to earnings is:

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

Or for Singapore Technologies Engineering:

P/E of 23.57 = SGD3.99 Ã· SGD0.17 (Based on the trailing twelve months to June 2019.)

### Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each SGD1 the company has earned over the last year. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### Does Singapore Technologies Engineering Have A Relatively High Or Low P/E For Its Industry?

We can get an indication of market expectations by looking at the P/E ratio. The image below shows that Singapore Technologies Engineering has a higher P/E than the average (12.3) P/E for companies in the aerospace & defense industry.

Its relatively high P/E ratio indicates that Singapore Technologies Engineering shareholders think it will perform better than other companies in its industry classification. Clearly the market expects growth, but it isn't guaranteed. So investors should delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means unless the share price increases, the P/E will reduce in a few years. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Singapore Technologies Engineering's earnings per share were pretty steady over the last year. And over the longer term (5 years) earnings per share have decreased 1.5% annually. So it would be surprising to see a high P/E.

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

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. In other words, it does not consider any debt or cash that the company may have on the balance sheet. 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.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting Singapore Technologies Engineering's P/E?

Singapore Technologies Engineering has net debt worth 11% of its market capitalization. This could bring some additional risk, and reduce the number of investment options for management; worth remembering if you compare its P/E to businesses without debt.

### The Verdict On Singapore Technologies Engineering's P/E Ratio

Singapore Technologies Engineering has a P/E of 23.6. That's higher than the average in its market, which is 12.9. With modest debt but no EPS growth in the last year, it's fair to say the P/E implies some optimism about future earnings, from the market.
