Three former Janus Capital Management employees have been charged with market timing abuse by the US Securities and Exchange Commission just over two years after the firm paid a $226.2m (€176.7m) settlement for making undue profits from its investors.

The SEC's division of enforcement alleges three former Janus employees, Warren Lammert, Lars Soderberg and Lance Newcomb, allowed or facilitated improper trading practices, violating federal securities laws.
