# Does MTR Corporation Limited's (HKG:66) P/E Ratio Signal A Buying Opportunity?

This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We'll look at MTR Corporation Limited's (HKG:66) P/E ratio and reflect on what it tells us about the company's share price. Looking at earnings over the last twelve months, MTR has a P/E ratio of 18.31. That corresponds to an earnings yield of approximately 5.5%.

### How Do You Calculate MTR's P/E Ratio?

The formula for P/E is:

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

Or for MTR:

P/E of 18.31 = HK\$48.4 Ã· HK\$2.64 (Based on the year to December 2018.)

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

A higher P/E ratio means that buyers have to pay a higher price for each HK\$1 the company has earned over the last year. All else being equal, it's better to pay a low price -- but as Warren Buffett said, 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'

### How Does MTR's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. If you look at the image below, you can see MTR has a lower P/E than the average (20.6) in the transportation industry classification.

This suggests that market participants think MTR will underperform other companies in its industry. Since the market seems unimpressed with MTR, it's quite possible it could surprise on the upside. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. When earnings grow, the 'E' increases, over time. That means even if the current P/E is high, it will reduce over time if the share price stays flat. Then, a lower P/E should attract more buyers, pushing the share price up.

MTR shrunk earnings per share by 6.6% last year. But over the longer term (5 years) earnings per share have increased by 3.3%.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

Don't forget that the P/E ratio considers market capitalization. So it won't reflect the advantage of cash, or disadvantage of debt. 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 MTR's P/E?

MTR has net debt worth 10% 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 Bottom Line On MTR's P/E Ratio

MTR's P/E is 18.3 which is above average (10.4) in its market. 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.

When the market is wrong about a stock, it gives savvy investors an opportunity.
