I get the logic Growler regarding fair value but do you factor in the potential? Markets are forward looking and there is also investor sentiment/hopium at play... so out of genuine interest, what is your realistic entry point at this point in time?

Im a boring, fundamental investor, (and an accountant), but have learnt over the years you cant always get the entry point you want based on the numbers alone. If a stock gets noticed on the ASX, (and becomes fashionable, for lack of a better word), the horse can bolt. Ive missed too many companies over the years when in the early stages they progressively become a de-risked opportunity. The most recent example for me was Mineral Resources... still kicking myself over that one.
