Greece's debt crisis will take another twist this year—causing equities to sink by 10 percent—according to the head of research at a U.K.-based assessment manager firm.
John Haynes of Investec Wealth & Investment told CNBC on Friday that markets would correct as investors became fearful again of "contagion" across the euro zone from Greece.
However, rather than advising investors to head to the sidelines, he said the correction would be a "buying opportunity" that he would "really like."
"I don't really care if Greece stays in the euro zone or not; I think what will happen is we'll get a 10 percent correction in equity markets as people go 'argh.' It's political risk for everybody else'," Haynes told CNBC.
"It (the correction) would be a buying opportunity," he later added.
Bob Parker, a senior advisor at Credit Suisse, agreed that such a correction would be a buying opportunity. But unlike Haynes, he said the risk of contagion was minimal because of the European Central Bank's quantitative easing program and that fact that countries like Ireland, Spain and Portugal have already completed successful debt restructurings.
"Contagion risk is going to be very small," Parker told CNBC on Friday.
"We're in a very different economic place today than we were four or five years ago," he said. "We shouldn't worry about it."
