Well we're talking about something that hasn't happened here anyway. The stock hasn't been halted as of when I type this, altho if things keep up it very well could be. All PS has done so far is to change HTDS' status and add the Caveat Emptor symbol. This won't affect trading even while HTDS seeks a new CUSIP.
Once the new one is obtained the old one will no longer be active as of whatever date the new one comes into effect - usually set by FINRA & PS.
I would support your theory on pressure building up but only if the stock were actually halted for something very important such as some pending major news release and not a CUSIP change.
Anyway, let's just agree to disagree. HTDS isn't halted and tomorrow's another day for ppl to flip it and make some money.
