In the past week, shares of Dropbox have gained more than 40 percent.

Another recently-public tech company, Zuora, also jumped in Monday's session, gaining 7 percent.

Rishi Jaluria, senior research analyst at D.A. Davidson & Co, said the move in Dropbox was "likely follow through from last week." Jaluria noted that trading volume in the stock has been heavy in recent sessions.

As of early afternoon trading, more than 16.2 million shares of Dropbox changed hands. That figure exceeds the 30-day average volume of 3.7 million shares.
