Is Box a buy? Venture capitalist Rick Heitzmann, whose firm is a major investor in Pinterest, is a believer in Box.
Despite Box's surge of as much as 70 percent in its trading debut on Friday, the CNBC "Fast Money Halftime Report" traders are split on whether it's worth playing.
In an interview Friday, Heitzmann, FirstMark Capital managing director and founder, said he views Box as a buy and hold opportunity.
"Although unprofitable now, Box outlined long-term operating margins which leads to significant profitability," Heitzmann said.
Short Hills Capital's Steve Weiss is cautiously optimistic about Box.
"As long as they live up to what they have said they would, in terms of guidance, it's the only way to play this right now in the public market," he said.
But it wasn't all optimism for the cloud storage company.
