Bill Gross, the co-chief investment officer at bond investor Pimco, said he doesn't expect the Federal Reserve to tighten monetary policy before 2016.

On his Twitter feed on Sunday, the closely followed Gross tweeted, "Gross: So bonds come out of their coffin & it’s not even Halloween. #Bernanke says follow policy rate & we agree. 2016 tightening @ earliest."
