Janus’ third-quarter net income rose 296% to $32.5 million, or 18 cents per diluted share, up from $8.2 million, or 5 cents per diluted share, in the third quarter of 2009.

“Long-term performance remains strong, and out mathematical strategies in particular have demonstrated consistent improvement,” said Janus CEO Richard M. Weil. “We are also continuing to make progress in our fixed income and global businesses. As we look ahead, we think today’s equity markets are creating terrific opportunities for active management.”
