Where the return came from

Yearly rates to Mar 2026, per-share figures restated for splits and bonuses.

OverReturn a yearEarnings growthChange in P/EDividend yield

3 years+12.9%+16.9%−3.8%0.4%
5 years+19.8%+28.4%−7.0%0.4%
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 over 5 years includes one-off items (exceptional items and the result of businesses sold or closed) of more than a tenth of the profit of the year to Mar 2021.
