I took a look at XXXA, one of the other companies which I owned when they caught a suspension. Apparently, it trades as "caveat emptor." PinkSheets/OTC only displays the last sale, and will not quote a bid or ask. It's like playing darts with a blind man. There are probably some serious restrictions on trading. I hope Miracor at least has that route. SEC filings are still shown, so phone numbers and email addresses of principals can still be located in the event that shareholders wish to act upon them. I only have 1000 shares post-split of XXXA, so it's no big deal to me, but it's nice to be able to contact them.
My other one, ARTA was suspended after successfully emerging from BK, and there is no further tradable activity. They reported to the SEC that they had no existing business, so they intentionally refused to report, even though I have found info which suggests they have massive amounts of equity left in their portfolio. I am forced to sit on that position while the liquidator completes his work and I cannot trade it whatsoever. I do expect a distribution from the BK estate.
