### How Do You Calculate HK Electric Investments and HK Electric Investments's P/E Ratio?

The formula for P/E is:

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

Or for HK Electric Investments and HK Electric Investments:

P/E of 22.59 = HK\$7.8 Ã· HK\$0.35 (Based on the trailing twelve months to December 2018.)

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

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. 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

When earnings fall, the 'E' decreases, over time. That means unless the share price falls, the P/E will increase in a few years. Then, a higher P/E might scare off shareholders, pushing the share price down.

HK Electric Investments and HK Electric Investments saw earnings per share decrease by 8.7% last year. And EPS is down 10% a year, over the last 5 years. So it would be surprising to see a high P/E.

### Does HK Electric Investments and HK Electric Investments Have A Relatively High Or Low P/E For Its Industry?

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

The 'Price' in P/E reflects the market capitalization of the company. Thus, the metric does not reflect cash or debt held by the company. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

### Is Debt Impacting HK Electric Investments and HK Electric Investments's P/E?
