Some recent tech IPOs are on a tear, and there's one that has more room to soar

Since going public, shares of Roku ROKU , Stitch Fix SFIX , DocuSign DOCU and Dropbox DBX have all soared, rising a respective 399 percent, 193 percent, 48 percent and 25 percent from their IPO price. "It has a lot of appeal technically as a name that potentially could start to play catch-up," Mark Newton, president and founder of Newton Advisors, said Tuesday on CNBC's " Trading Nation ," acknowledging the stock is down meaningfully since its post-IPO high. Shares of Dropbox, a San Francisco-based cloud storage company, have traded in a volatile range, rising as high as $43 a share in June only to touch a low of $24.78 just last week.
