Ann: ASX Update on status of ASX Directions, page-308

The answer to your question could be along the lines of 'so the performance shares don't get sold/traded prior to conclusion of an investigation into their validity'.

Of course this is not stated clearly by any of the parties, but reading between the lines this is a possibility/probability. The volatility reason was likely to be invoked due to concern these were being sold in the period before suspension (though subsequently they weren't). Asic investigation comes up clean & there is no issue, and it trades again, subject to ongoing compliance with listing rules ...

Asic will not revoke the market operator license, why would they - that's a fantasy. And all you have is a couple of accusations by ISX which are yet to be considered in court. If anything, the ISX v ASX case might more clearly define the role of the market operator, but that's it.

A royal commission will not, nor should happen. The people who lose on the stockmarket unfairly generally have a beef with the directors of the company they invested in, its rarely, if ever anything to do with the market operator - though plenty are quick to blame.
