The Massachusetts securities division regulator has filed an administrative action against RBC Capital Markets LLC and one of its former registered representatives, Michael D. Zukowski relating to sales of inverse, leveraged, inverse-leveraged, and other non-traditional exchange traded funds. The regulator seeks an order, among other things, requiring RBC and Zukowski to make full restitution to investors who lost money in as a result of unsuitable sales such funds, and pay fines.
