Investors should look toward European equities to outperform in 2014 as companies based there continue to see profit growth, despite relatively weaker overall economic progress, Goldman Sachs' Peter Oppenheimer told CNBC on Tuesday.

"We're pretty optimistic of equity markets still," Oppenheimer said on "Squawk on the Street." "Clearly there's been a big period of outperformers of equities relative to government bonds. We expect that to continue."
