I'm in since May 2015, then bought more at too high a price throughout 2015, but have held all even when the SP tanked, as I have always believed in the LT story for ISX. Topped up over the years since, held all.
Such is my belief, I bought more recently at 49c to 71c, but these latter buys I have under a SL. I plan to continue to buy more as the story strengthens and justifies/supports higher SPs. There is enormous potential for serious growth ahead, and no reason to stop buying as that unfolds..
It's my biggest holding for sure, but not my only high conviction stock.
ISX LT posters have been invaluable to me, with your sharing of knowledge to help us better understand the Co - thanks to all.
