As explained in our education section, short interest is a useful sentiment indicator that measures the level of investor pessimism toward a stock. While it isn't always a simple "long only" indicator, it can give you insight into situations where you might see concentrated buying demand. The purpose of this post is to highlight heavily-shorted stocks that could be in the midst of a potential short covering rally. More details about the methodology are listed below.

Companies included in today's scan are: General Growth Properties Inc(GGP), MGM Mirage (MGM), Ford Motor Co (F), Zale Corp. (ZLC), Doral Financial (DRL), CBL & Associates Properties (CBL), MarineMax (HZO), Las Vegas Sands Corp. (LVS), Lamar Advertising (LAMR), Dendreon Corp (DNDN), Trina Solar Limited (TSL), Geron Corp. (GERN), Continental Airlines (CAL), Pre-Paid Legal Services (PPD), Weingarten Realty Investors (WRI), General Motors Corp (GM), Yingli Green Energy Hold Co Ltd (YGE), NetSuite Inc. (N), Synta Pharmaceuticals Corp. (SNTA), AeroVironment, Inc. (AVAV), WMS Industries (WMS), Wynn Resorts Limited (WYNN), Cimarex Energy Co (XEC), LDK Solar Co Ltd (LDK), Cepheid (CPHD).

Methodology - the query scans my database of companies which has some basic filters to eliminate stocks that don't trade frequently. The table above is a filtered list of stocks that have at least 10 percent of their float sold short and showed a gain in the previous trading day. I use this as a tool for finding situations where stocks with heavy short interest have begun to move.
