P/E Ratio (Price-to-Earnings Ratio)
Learn how the P/E ratio is calculated, how Malaysian investors read it, and why it needs context. Includes a Company A worked example in RM.
What is P/E Ratio (Price-to-Earnings Ratio)?
The P/E ratio shows how many ringgit investors pay for each ringgit of a company’s annual earnings. It is calculated by dividing the share price by earnings per share, usually over the trailing 12 months. It is not meaningful when a company is making a loss.
How it is calculated
Divide the share price by earnings per share (EPS), usually the trailing 12-month figure that adds up the latest four reported quarters.
P/E ratio = Share price ÷ Earnings per share (trailing 12 months)
How Malaysian investors use it
On Bursa Malaysia, compare P/E within a sector such as banking or plantation. Earnings can swing sharply, so check the quarterly report before relying on one figure.
Worked example: Company A
Hypothetical Company A, trailing 12 months:
| Item | Figure |
|---|---|
| Net profit | RM60 million |
| Weighted average shares | 400 million |
| EPS | RM0.15 |
| Share price | RM2.40 |
| P/E ratio | 16.0 times |
Investors pay RM16 for each RM1 of Company A’s annual earnings. That means little until it is compared with peers.
Common mistakes
- Calling a low P/E cheap without checking whether earnings are falling.
- Comparing banks with plantation firms, which earn very differently.
- Mixing forecast EPS with a one-off strong quarter.
Related terms
- Income statement: source of the net profit behind EPS.
- Earnings per share: the denominator in this ratio.
- TTM (trailing twelve months): why the latest four quarters are the base.

Frequently asked questions
Is a high P/E always bad?
No. A high figure can reflect strong expected growth, or a share price that has run ahead of earnings.
Why does P/E fail for loss-making companies?
A negative EPS gives a number that does not describe earnings power, so the ratio is treated as not meaningful.
Should I use trailing or forecast EPS?
Trailing EPS uses reported results and can be checked. Forecast EPS is an estimate, so note which one you use.
