Bonds have outperformed stocks thus far in 2016 with the Barclay's U.S. Aggregate Bond Index up 2 percent versus a 1.5 percent rise in the S&P 500. Christine Hurtsellers, fixed income chief investment officer at Voya (VOYA) - Get Voya Financial, Inc. Report , does not expect bonds to back down in the second half. 'The bond market did a much better job last year pricing in lower revenue growth and plus you have the Federal Reserve trying to raise rates,' said Hurtsellers. 'That doesn't necessarily mean that interest rates are going to go up much in the U.S. so I don't expect a huge selloff in bonds.' Hurtsellers expects weak domestic growth and heavy foreign buying to push the yield on the benchmark 10-year Treasury to around 1.5 percent in the coming months from its current 1.85 percent level.
