What happened

Shares of Ellie Mae Inc (ELLI) fell on Monday as investors feared rising mortgage rates will lead to lower purchase and refinance volume. Shares lost as much as 10.9% before ending the day with an 8.6% decline.

So what

Ellie Mae is a mortgage software company that helps banks comply with the onslaught of new regulations thrust onto lenders after the 2008 housing crisis.

The company generates revenue on subscriptions by licensing its products to mortgage professionals. In addition, it also employs "success-based" pricing, which means that a portion of its revenue is inherently tied to mortgage volume.

Ellie Mae's short-term business prospects are inextricably linked to interest rates. In the last week, mortgage rates have surged, and Ellie Mae's share price has declined four trading days in a row. reports that interest rates on 30-year fixed-rate mortgages rose to 4%, up from 3.62% on Election Tuesday.

Now what

Higher mortgage rates may discourage the marginal purchase or refinance, but it pays to look at the big picture. Conventional 30-year mortgages carried an interest rate of 4% as recently as December 2015. In context, the recent rise isn't as devastating as it may seem to be.
