How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

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

Or for Lai Si Enterprise Holding:

P/E of 39.27 = MOP0.628 ÷ MOP0.016 (Based on the trailing twelve months to December 2019.)

(Note: the above calculation uses the share price in the reporting currency, namely MOP and the calculation results may not be precise due to rounding.)

Is A High Price-to-Earnings 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 Does Lai Si Enterprise Holding's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. As you can see below, Lai Si Enterprise Holding has a much higher P/E than the average company (7.6) in the construction industry.

Lai Si Enterprise Holding's P/E tells us that market participants think the company will perform better than its industry peers, going forward. The market is optimistic about the future, but that doesn't guarantee future growth. So further research is always essential. I often monitor director buying and selling.

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. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

Lai Si Enterprise Holding's 176% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive. Unfortunately, earnings per share are down 46% a year, over 3 years.

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

Don't forget that the P/E ratio considers market capitalization. That means it doesn't take debt or cash into account. 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.
