How Do I Calculate China Water Affairs Group's Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for China Water Affairs Group:
P/E of 10.14 = HK$7.89 ÷ HK$0.78 (Based on the trailing twelve months to September 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. 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.
How Growth Rates Impact P/E Ratios
P/E ratios primarily reflect market expectations around earnings growth rates. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. Then, a lower P/E should attract more buyers, pushing the share price up.
China Water Affairs Group increased earnings per share by an impressive 23% over the last twelve months. And it has bolstered its earnings per share by 30% per year over the last five years. This could arguably justify a relatively high P/E ratio.
How Does China Water Affairs Group'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 (7.5) for companies in the water utilities industry is lower than China Water Affairs Group's P/E.
Its relatively high P/E ratio indicates that China Water Affairs Group shareholders think it will perform better than other companies in its industry classification. The market is optimistic about the future, but that doesn't guarantee future growth. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.
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. Thus, the metric does not reflect cash or debt held by the company. 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.
How Does China Water Affairs Group's Debt Impact Its P/E Ratio?
China Water Affairs Group has net debt worth 66% of its market capitalization. This is a reasonably significant level of debt -- all else being equal you'd expect a much lower P/E than if it had net cash.
The Verdict On China Water Affairs Group's P/E Ratio
China Water Affairs Group's P/E is 10.1 which is below average (11.3) in the HK market. The company has a meaningful amount of debt on the balance sheet, but that should not eclipse the solid earnings growth. If the company can continue to grow earnings, then the current P/E may be unjustifiably low.
