Goarmy: long after the SEC suspends a stock that is not registered with the SEC (eg., THRA) FINRA can delete the ticker symbol as an 'inactive security' if and when there has been no trading activity for a prolonged period of time.
THRA has had only 3 trading days since June, probably just enough to make the stock appear as marginally active to avoid the 'inactive security' requirements for FINRA to delete the symbol.
The dollar value of the 3 trading days since June is quite insignificant so there is no plausible explanation for keeping the stock barely active.
My guess is that there is a convertible debenture lender biding their time to unload as many shares as possible with a false pump in the future, and if so then the lender could be keeping the stock on life-support with the occasional trading day volume.
