Hey Shares888. A chart can say 1,000 words eh? I see where you're going with the % price change over a 12 month period and that's one way of looking at it. I was looking at it from an actual price/index comparison.
As you can see, RES tracked the XAO closely from mid March through till late September when (as previously stated) the market learned of delays to NEMA & IWULA approvals.
