misrepresentation or omission of important information about securities;
manipulating the market prices of securities;
stealing customers' funds or securities;
violating broker-dealers' responsibility to treat customers fairly;
insider trading (violating a trust relationship by trading on material, non-public information about a security); and
--------------------------- AGREE THE NSS POSITON COULD BE THE REASON FOR INVESTIGATION
