How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share (in the reporting currency) ÷ Earnings per Share (EPS)

Or for Chongqing Machinery & Electric:

P/E of 5.36 = CN¥0.64 (Note: this is the share price in the reporting currency, namely, CNY ) ÷ CN¥0.12 (Based on the trailing twelve months to December 2018.)

Is A High Price-to-Earnings 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 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. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means even if the current P/E is high, it will reduce over time if the share price stays flat. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Chongqing Machinery & Electric increased earnings per share by a whopping 33% last year. And its annual EPS growth rate over 3 years is 1.9%. I'd therefore be a little surprised if its P/E ratio was not relatively high. But earnings per share are down 2.7% per year over the last five years.

This suggests that market participants think Chongqing Machinery & Electric will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

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

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. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

Chongqing Machinery & Electric's Balance Sheet

Chongqing Machinery & Electric's net debt equates to 25% of its market capitalization. While that's enough to warrant consideration, it doesn't really concern us.

The Verdict On Chongqing Machinery & Electric's P/E Ratio

Chongqing Machinery & Electric trades on a P/E ratio of 5.4, which is below the HK market average of 12. The company hasn't stretched its balance sheet, and earnings growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified.
