Bill Gross, who reigned for decades as the Bond King at Pacific Investment Management Co., is retiring more than four years after jumping to Janus Henderson Group Plc from the fixed-income giant he co-founded.

“I’ve had a wonderful ride for over 40 years in my career -- trying at all times to put client interests first while inventing and reinventing active bond management along the way,” Gross said in a statement Monday.

Gross, 74, has run the Janus Henderson Global Unconstrained Bond Fund since late 2014, shortly after he suddenly left Pimco in the midst of a management clash. His annualized returns of less than 1 percent at Janus failed to live up to his stellar long-term record from the Pimco era.
