More Offense, Less Defense: CIO

The stock market is unlikely to see gains in the second half of 2013 as strong as in the first half, but a few sectors offer potential, James Dunigan of PNC Asset Management Group said Monday.

"In the second half of the year, we think it's probably better to play more offense than defense," he said. "So, that 12 percent growth we saw in the S&P probably does not repeat itself in the same way in the second half of the year."

On CNBC's "Fast Money," Dunigan said that certain sectors were poised to offer opportunity for the rest of the year.

"So, where we started off this year with staples, utilities, telecom outperforming, we think it's time to restructure and reposition portfolios more in those cyclical names, and that would be consumer discretionary, industrials, as you say, materials and financials," he said. "More offense as opposed to defense."

Dunigan, with $116 billion in assets under management, said that earnings would drive stock gains.

"I think it'll be difficult to get a read on the second quarter," he added, saying that he would look to guidance in quarterly earnings reports which kick off this week.

Dunigan also said that he thought yields on the 10-year Treasury bill would average 2½ percent for the second half of the year.

"Could it touch 3 percent? It certainly could, but we think based upon those economic fundamentals that we see – and they are improving – likely that we've overdone things a bit here and it settles back in and averages 2 ½ percent for the balance of 2013," he added.

"There's no doubt that the data is improving. Seventy percent of economic data in June beat the estimates, so higher better data begets higher rates, without a doubt."
