Keep hyperlinks in homepage posts

When I create a post and include hyperlinks within the post content, they disappear as links in the summary format on the homepage.
However, they are maintained if you view the post’s page.
Is there some way to keep them in the summary format?

For example: See the “In March, Brian Honigman Taught AAF Jackson about Native Advertising” post. Note: “Brian Honigman” and “Slideshare” are both supposed to be links. > http://aafjackson.org
