Gross, who is the manager of the Janus Global Unconstrained Bond Fund , told Barron's that he does not expect U.S. Treasury yields, which are currently around 1.7 percent, to change dramatically this year.

The 71-year-old portfolio manager said he sees investment opportunities in merger arbitrage situations, such as Berkshire Hathaway's  (>> Berkshire Hathaway Inc.) acquisition of Precision Castparts last year or Anheuser Busch InBev's (>> Anheuser-Busch Interbrew) planned acquisition of rival SABMiller (>> SABMiller plc).

Additionally, Gross said he likes closed-end funds such as the Nuveen Preferred Income Opportunities Fund (>> Nuveen Preferred Income Opportunities Fd) and the Duff & Phelps Global Utility Income Fund (>> Duff & Phelps Global Utility Dividend Fd).
