Shareholder investment ratios connect a company’s accounting results with the market value and dividend return of its ordinary shares. The main measures are earnings per share, the price/earnings ratio, earnings yield, dividend per share, dividend yield, dividend cover and payout ratio.
These ratios answer different questions. EPS measures earnings attributable to each ordinary share. P/E reflects the price investors are willing to pay for those earnings. Dividend yield measures cash dividend return relative to market price, while dividend cover measures how safely current earnings support the dividend.
Why Investment Ratios Matter
Investors use these measures to compare performance over time, evaluate dividend policy and understand market expectations. Management and analysts use them when discussing valuation, capital allocation and shareholder returns. No ratio should be interpreted in isolation because share prices respond to future expectations, risk, interest rates and industry conditions.
Earnings per Share under IAS 33
IAS 33 requires basic and diluted EPS for entities whose ordinary shares or potential ordinary shares are publicly traded. A non-public entity that voluntarily presents EPS must also follow IAS 33. In consolidated statements, earnings are based on profit attributable to ordinary equity holders of the parent.
Basic EPS = Profit attributable to ordinary equity holders ÷ Weighted-average ordinary shares
The denominator is a weighted average because a share issued halfway through the year was not outstanding for the full period. Bonus issues, share splits and similar events generally require retrospective adjustment so comparative EPS remains comparable.
Diluted Earnings per Share
Diluted EPS shows the possible reduction in EPS if dilutive potential ordinary shares became ordinary shares. Examples include convertible debt, employee options, warrants and contingently issuable shares. Instruments that increase EPS or reduce loss per share are antidilutive and are excluded from diluted EPS.
IAS 33 requires basic and diluted EPS with equal prominence. It also requires reconciliations of the earnings numerators and share denominators and disclosure of instruments that could dilute EPS in the future.
Price/Earnings Ratio
P/E Ratio = Market price per share ÷ Earnings per share
A P/E of 15 means the market price equals 15 times current annual EPS. A high P/E may reflect growth expectations, perceived quality or low risk, but it can also indicate an expensive price. A low P/E may indicate weak expectations, high risk, cyclical earnings or undervaluation.
Earnings Yield
Earnings Yield = EPS ÷ Market price per share × 100
Earnings yield is the reciprocal of the P/E ratio. A P/E of 12 corresponds to an earnings yield of approximately 8.33%. It provides an earnings-based percentage return for comparison, but it is not the same as cash yield because not all earnings are distributed.
Dividend per Share and Dividend Yield
Dividend per Share = Ordinary dividends ÷ Number of ordinary shares
Dividend Yield = Dividend per share ÷ Market price per share × 100
Dividend yield measures cash distributions relative to the current share price. It ignores capital gains and losses. A high yield can be attractive, but it may also reflect a depressed share price or an unsustainable dividend.
Dividend Cover and Payout Ratio
Dividend Cover = EPS ÷ Dividend per share
Dividend Payout Ratio = Dividend per share ÷ EPS × 100
Dividend cover of 2 times means current earnings are twice the dividend. Higher cover normally provides a larger buffer, while lower cover means more earnings are distributed. The appropriate level depends on growth opportunities, cash needs, debt obligations and dividend policy.
Worked Example
| Information | Amount |
|---|---|
| Profit attributable to ordinary shareholders | $2,400,000 |
| Weighted-average ordinary shares | 8,000,000 |
| Total ordinary dividends | $960,000 |
| Market price per share | $4.50 |
Basic EPS = $2,400,000 ÷ 8,000,000 = $0.30.
Dividend per share = $960,000 ÷ 8,000,000 = $0.12.
P/E ratio = $4.50 ÷ $0.30 = 15 times.
Earnings yield = $0.30 ÷ $4.50 × 100 = 6.67%.
Dividend yield = $0.12 ÷ $4.50 × 100 = 2.67%.
Dividend cover = $0.30 ÷ $0.12 = 2.5 times. The payout ratio is 40%.
Interpreting the Ratios Together
| Observation | Possible interpretation | Further questions |
|---|---|---|
| EPS rising and P/E stable | Market price may rise broadly with earnings. | Are earnings recurring and cash-supported? |
| High P/E and low dividend yield | Market may expect growth and retained reinvestment. | Are growth assumptions realistic? |
| High dividend yield and low cover | Dividend may be vulnerable. | Is the low share price signalling risk? |
| High cover and low payout | More earnings are retained. | Are retained funds earning attractive returns? |
| Diluted EPS materially below basic EPS | Potential share dilution is significant. | Which instruments create the dilution? |
Limitations of Investment Ratios
- EPS depends on accounting policies, estimates and one-off items.
- P/E is unreliable when earnings are very small, negative or unusually volatile.
- Market price changes continuously while published earnings are periodic.
- Dividend yield ignores capital growth and tax differences.
- Dividend cover based on profit does not prove cash availability.
- Different industries have different growth, risk and payout patterns.
- Share buybacks can increase EPS without improving total profit.
IFRS 18 and Additional Per-Share Measures
IAS 33 continues to govern basic and diluted EPS. IFRS 18 introduces new presentation and management-defined performance measure requirements from annual periods beginning on or after 1 January 2027. When entities disclose additional per-share amounts, the numerator must comply with the relevant IAS 33 and IFRS 18 requirements and must not be presented more prominently than required EPS measures.
Practical Investor Checklist
- Compare basic and diluted EPS.
- Review the weighted-average share count and recent share issues or buybacks.
- Separate recurring performance from unusual gains and losses.
- Compare dividend cover with operating cash flow and debt obligations.
- Compare P/E and yield with peers using similar accounting periods and business models.
- Examine several years rather than one reporting period.
Frequently Asked Questions
What is the difference between EPS and dividend per share?
EPS measures earnings attributable to each ordinary share; dividend per share measures the cash distribution declared or paid for each share.
Is a high P/E ratio always good?
No. It may reflect strong growth expectations, but it can also indicate an expensive valuation or unrealistic expectations.
What does dividend cover of 1.5 times mean?
Current earnings are one and a half times the dividend. The payout ratio is approximately 66.7%.
Why is diluted EPS lower than basic EPS?
Dilutive potential ordinary shares increase the assumed share count or adjust earnings, reducing EPS.
Can a company have strong EPS but weak cash flow?
Yes. EPS is accrual-based and may be affected by credit sales, working capital, estimates and noncash items.

Conclusion
The most useful analysis combines correct calculations with context. A ratio, valuation, reconciliation or accounting treatment should be applied consistently, supported by evidence and interpreted with the entity’s facts, reporting framework and materiality in mind.
