I’m No Pollyanna, Stock Bull Says

Based on valuations and margins, the stock market still has room to grow, Delphi Management President Scott Black said Monday.

Estimating a "conservative" $105 in corporate earnings for large-cap stocks, up 8 percent year over year, he said that the market was trading at multiple of 15.3 times percent vs. a historical norm of 16.

On CNBC's "Fast Money," Black said that margins, also, were positive.

"The one good thing is that we're getting good operating leverage," he added, noting that even though earnings were up about 8 percent for the first quarter, revenues were only up 2.2 percent, equating to margins of 9.6 percent.

"This is the highest operating margin in the S&P since the third quarter of 2011," he said.

Black also responded to a Goldman Sachs note calling cyclical stocks undervalued.

"I would agree that some of the consumer staples are expensive," he said, adding that there were big technology names such as Qualcomm, EMC and Oracle, comprising a "homogenous risk class," which, "if you back out their excess cash, that are extremely cheap."
