I understand that you have a question regarding the symbol SFIO.
The Depository Trust Clearing Corporation, a company that offers a clearing service for Scottrade, has placed a Global Lock on this security. This means that any security under this lock is not able to be traded through any participating DTC brokers. Since SFIO has a Global Lock placed on it you will be unable to trade this security until the DTC lifts the lock.
Please note that when the DTC decides to implement a Global Lock, Scottrade has no authority to trade the locked security.
If you need further clarification, please contact your local Scottrade branch office for assistance. You may obtain the telephone number of your local branch office through our home page in the Branch Locator.
