If anyone would have actually looked at the details behind all those deal it would have been obvious that those deals were set up to be nothing but share selling schemes to enrich insiders. I had warned but people were too busy listening to the CFA who was in bed with management and distracted the attention away from the details of those toxic financing deals.
It's not so much "traders/flippers propping it up". It's lack of interest keeping it in the current channel.
PPS is less the issue on the greys, it's about volume/liquidity/no bid-ask.
What will happen most likely is this:
The PPS will move around a bit but it won't necessarily drop to .0001 or even close. The PPS can/may remain where it is but eventually it doesn't matter as there are no buyers/sellers...
I've watched many suspended tickers lose significant PPS % on trading resumption. Some remain at an "ok PPS" but you can't buy or sell shares there or anywhere for that matter...
