How Do You Calculate Guangdong Investment's P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for Guangdong Investment:

P/E of 22.27 = HK$16.80 ÷ HK$0.75 (Based on the trailing twelve months to September 2019.)

Is A High P/E Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each HK$1 of company earnings. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.

How Does Guangdong Investment's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. You can see in the image below that the average P/E (5.7) for companies in the water utilities industry is a lot lower than Guangdong Investment's P/E.

That means that the market expects Guangdong Investment will outperform other companies in its industry. Shareholders are clearly optimistic, but the future is always uncertain. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. Earnings growth means that in the future the 'E' will be higher. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Guangdong Investment's earnings per share grew by -2.9% in the last twelve months.

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

The 'Price' in P/E reflects the market capitalization of the company. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

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.

Guangdong Investment's Balance Sheet

The extra options and safety that comes with Guangdong Investment's HK$7.2b net cash position means that it deserves a higher P/E than it would if it had a lot of net debt.

The Bottom Line On Guangdong Investment's P/E Ratio

Guangdong Investment has a P/E of 22.3. That's higher than the average in its market, which is 10.2. EPS was up modestly better over the last twelve months. And the healthy balance sheet means the company can sustain growth while the P/E suggests shareholders think it will.
