I’m very novice when it comes to companies delisting. I suppose there are different types of delistings, however, in this instance, does it mean that TTB will actually completely cease to exist as a company or simply become non-ASX? and what would happen to my shares (and fund) if I do nothing?
What by law would happen to my shares? Because I find it odd that people are still buying this stock now….
Luckily I have very little invested in this lot, but a good learning experience
