Trades Ideas for July 27

Besides the stocks in the last 3 posts, I will also be looking at the following possible trades:

SIRI - Long on break of descending wedge.  Good volume has been coming in the past 2 days and could be ready to make a move here.

ARNA - Short.  The price has been way overextended IMO and the stock actually closed weak today after gapping up and hitting highs.  Could retrace towards 5.25,
