I can find a pure chart quite frustrating. My logical side wants to know more - I battle with the "its only the price you need to know, stupid" approach.

To see what else may be of influence, I can add an overlay of the share's eps (with a constant multiple, of my own choosing)
OK, so it seems that the eps is predicted a year ahead by the price, and maybe there is something else in the mix. So I add an oil price. Oil in rands, not dollars.

So I now see an elaborate option on the rand oil price!
