Rimm acting sloppy

Here is a chart on rimm. It looks like it is acting very sloppy. It tried to close at a new high a few days back and failed. Then the news from aapl sent this stock down about 10pts. It is now finding support at the 50ma.  The cmf is negative so money might be gonig somewhere else. aapl mabye??  Well i shorted this stock the other day and will cover if it breaks and closes at a new high. But this was a huge gainer last yr, so i am speculating that this will see some down time. A break and a close below the 50ma could be a sign that RIMM is on its way down a little bit. Not too comfortable about this play, but this stock could drop 10-20 more points in the months to come so that reward is nice.
