Yes, this is impossible to believe. Different stocks already have different margin requirements. Turning off margin trading for specific stocks is a fundamental system requirement.
- tptacek 6y agoI think all these margin discussions are a red herring. The clearinghouse requirements are based on the total number of shares sold, not the total sold on margin. As I understand it, clearing is mutual insurance against a disaster at the brokerage, not against customers randomly defaulting.
