Shares of Ellie Mae (ELLI) are up an impressive 33 percent thus far in 2016 and an even more striking 1,100 percent since the mortgage software company went public in April 2011. Right now Ellie Mae possesses about a quarter of the market in which it competes, and the company's CEO Jonathan Corr said there is 'more runway ahead.' 'We have a lot of leverage as a vertical SaaS (Software as a service) company,' said Corr. 'As we pick up more lenders and the industry becomes more automated we will benefit from the rising tide.' Ellie Mae provides enterprise mortgage origination technology solutions for mortgage bankers, mortgage brokers, community banks, credit unions and other mortgage lenders. The company went public at a price of $6 a share five years ago last month. TheStreet's Gregg Greenberg reports from Wall Street.
