LEAT is a VERY interesting example from the group of 35. I can see why it wouldn't be a positive example to cite in a claim for a bright future for ANWM.
It actually traded with higher volumes and at much higher prices while on the grey market than it has since it returned to PK. The stock priced dropped dramatically: http://ih.advfn.com/p.php?pid=historical&symbol=LEAT
I assume the other 3 that returned to PK are equally negative. Getting back to PK status means liquidity returns and market forces come into play. The stock resets to market value, which is likely to be very substantially lower.
JAMN is not a PK, but an SEC fully reporting OTCBB stock.
