Bought a put yesterday after bad earnings for Dec 1st, Strike 19.00 for a 0.57 debit.
Sold too early this morning for .97 (it's now worth 1.41 :-/ )
Re-entered today at 17.83 when the 18.05 resistance from June 2012 was hit.
Next target is at least 17.37 again from 2012.
Hard to determine a good exit when there isn't any near-term support levels. But the Trend is definitely bearish right now
