What is a good price-to-earnings ratio?
A price-earnings ratio (also called PE ratio or PER) looks at a company’s share price relative to its earnings per share. This means you can see how much investors are willing to pay for its shares.
The PE ratio reflects market expectations. A high price-to-earnings means investors expect growth from the company, while a low PE ratio may mean the company is undervalued or is facing challenges.

Analysts use the PE ratio to work out the current perception of a company in 2 ways:
To work out a company’s PE ratio, you need to look at:
The PE ratio formula is:
For example, if a company’s stock is priced at AED 50 per share and its earnings per share (EPS) is AED 2, the PE ratio can be calculated in the following way: 50 ÷ 2 = 25. This means investors are paying AED 25 for every AED 1 the company earns.
Alternatively, most online trading brokers (like HSBC WorldTrader) list PE ratios along with other data about a company, so just look for out for that.
There are 2 main types of PE ratios:

PE ratios tend to rise in bull markets, reflecting investor optimism, while they often fall in bear markets, as investors become more cautious.
Technology and healthcare companies often have high PE ratios as they’re seen as having strong growth potential. Meanwhile, industries like manufacturing and utilities often have lower PE ratios because they may have slower but steady growth.
If a company has a negative price-to-earnings ratio, it means it’s not making a profit. This could be because of:
A negative or low PE ratio doesn’t always mean a company is a bad investment. Look at other factors and the broader market context. If it is deemed to have strong growth prospects and is considered undervalued, it could be a good opportunity.
