Re: "Maybe they dont need retailers at that point."
That's the worst thing for retail shareholders, when the company -- which issues to large investors who make their money by selling into retail -- decides it doesn't need more cash from the large investors. If it 'goes private' by not filing, rather than by a share buy-back, the company simply gives 'the finger' to retail holders saying, to use your words, "we don't need you any more."
Of course, those companies are pretty much giving up on going back to public trading, killing the hopes of retail stuck-holders. So, in any such scenario, the future for retail share holders is typically pretty bleak.
If 'true experts' trade the stock while it is on the expert market, that might suggest that they think the company will get back to trading. But if that leak in the trading rules -- that allows foreign retail buyers to buy EM stocks -- isn't plugged, then EM trading action isn't necessarily a positive thing. I know this for a fact based on another stock I bought with the intention of holding long (meaning over a year), but it went from NT 10-K to EM to revoked, It traded pretty heavily on the EM, which, I think, caught the attention of the SEC, which shut it down because 'true experts' weren't trading it.
