Where the return came from
Yearly rates to Mar 2026, per-share figures restated for splits and bonuses.
| Over | Return a year | Earnings growth | Change in P/E | Dividend yield |
|---|---|---|---|---|
| 1 year | −46.7% | – | – | 0.0% |
| 3 years | −13.0% | – | – | 0.0% |
| 5 years | +8.8% | – | – | 0.0% |
Return is price growth plus the average dividend yield. Change in P/E is (1 + price growth) / (1 + earnings growth) - 1, so the parts compound rather than add. Earnings growth and the change in P/E are left empty where earnings per share at either end of the window was a loss or is not on record.
