The DTC suspended the stock. "The DTC provides securities movements for NSCC's(National Securities Clearing Corporation) net settlements, and settlement for institutional trades (which typically involve money and securities transfers between custodian banks and broker-dealers), as well as money market instruments. DTC is a member of the U.S. Federal Reserve System, and a registered clearing agency with the Securities and Exchange Commission."
The SEC didn't suspend the stock. Thats why it's not showing up on sites that show suspended stocks. Brokers will use their own discretion to suspend trading based on a DTC Global Lock. Hence why there is still some trading. Not every broker chose to suspend trading even though there is potential fraud occurring with settlements.
Personally, when the dust clears, I think ETMM is going to have to answer a lot of questions. As well as CDLR.
