Ex-Rights / Ex-Dividend Calculator
Compute the XR/XD reference price with the official exchange formula — cash dividends, bonus/split shares and rights issues combined.
Official exchange formula: XR/XD ref = (prevClose − dividend + rightsPrice × rightsRatio) ÷ (1 + bonusRatio + rightsRatio). Forward-adj factor = ref ÷ prevClose; chain factors across multiple events.
