Forget upheavals, stay long on this market: Pro

As stocks turned higher at the start of the week, funds manager Sarat Sethi said Monday investors should remain long and get ready to buy on pullbacks.

"I think geopolitics are playing such an important part today in the short-term market, but I think longer term we are still bullish on this market," said Sethi, who oversees $3.9 billion in assets as managing director at Douglas C. Lane. "And I think we end up the year higher, and I think you're going to get opportunities along the way to get good companies and invest in good companies."

On CNBC's "Halftime Report," Sethi noted stock selloffs over the past two weeks, where the market dipped sharply. "Some of the good stocks were down even 10 (percent)," he said. "That's when you go after them and you say, 'Now, I'm going to put more capital to work.'"

Sethi said he favored such stocks such as Delphi and Harman International.

"I love the auto suppliers," he said. "When you look at where the semiconductor sales are, the auto components are going through the roof, and you've still got huge demand, not just in the U.S. but globally. So, those companies are trading at below-market multiples, balance sheets that are improving, they're starting to pay dividends."

The drop in oil prices below $100 a barrel would also benefit sectors such airlines, he added.

"You've still got the largest expense for airlines coming down," he said. "I think that's an opportunity you've got to look at."

Sethi's top five holdings included BorgWarner, Qualcomm, Delta Air Lines, United and Illumina.
