Catherine Wood, founder and CEO of Ark Invest, and Christopher Retzler, portfolio manager at Needham Funds, are both searching for firms that are going to benefit from the move to the cloud and to mobile.
Wood likes Amazon. She points out that Jeff Bezos, the firm's founder and CEO, is utilizing web services, but his next move is logistics.
"He's buying planes, boats and airports, so we think this is a huge play," she said. "Not only on online retail, but also infrastructure as a service, which he believes could be as big as retail."
Wood believes Amazon will reach a $1 trillion market valuation.
