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
1 year−45.1%−1.3%−44.4%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.
