Don't know about surge. Patience is the key in my view. If the story unfolds as we hope then the fundamentals can not be ignored. It is at time thing, that is why most of my holdings are parked in the SMSF. Been holding for ages.
It is always more difficult to get transparency (from a market view) when the investee company is private (TSI) and you do not have control. This always discounts the share value. Fix this and I believe true value is substantially higher.
