On Friday, we will be watching for a Fast Ball continuation in Amerisourcebergen Corp (ABC). The stock moved lower on heavy news-driven volume, as Wal Mart announced it would sell some 300 generic drugs for $4 per 30 day supply.

Walgreen Co. (WAG) also left a Fast Ball on the news.

In retail (RLX.X), we will have Double Header Ann Taylor Stores Corp (ANN) and Infield Fly Autozone (AZO) on screen, looking for a move lower.

Finally, we will have Weight Watcher's International Inc (WTW) on the radar throughout the session. The stock left a reversal on the daily chart and looks ready to retrace some of its recent gains.
