Shares in realtor.com operator Move Inc. surge

Shares in realtor.com operator Move Inc. surged more than 10 percent today after Citron Research — the company that briefly sent shares in Zillow on a roller coaster ride last year with a skeptical 18-page research report — revealed on Twitter that it’s long on Move.

Another possible reason for the upsurge: The board of directors of the National Association of Realtors voted Saturday to hold a special meeting in July to discuss giving realtor.com — the official listing site of NAR — more leeway to compete with rivals like Zillow and Trulia.
