$YRIV - This is really getting extended now. A quick spike to 1.67ish - 1.75 is a good short opportunity. But be very careful. Lots of shorts are getting crushed on this.  

$RKDA - This is extremely bullish. Early shorts are getting crushed. I believe it still has potential to run above 10 tomorrow. So not touching on the short side yet. Just watching. I also think there might be an offering coming up. 

$BYND - Tried to have its first green day after a week of consolidation but still failed to hold it's gains. Will be on watch to break 175, consolidate and hold. May be an overnight position if it proves itself. 

$AMAG - This earnings winner is getting extended. Needs some consolidation. A gap down and a quick spike to $12.25 is a short signal. Has atleast a $1.00 downside potential tomorrow.

$YTEN - Seems to be an earnings winner. A morning spike and a dip to mid 1.20's is an ideal buy for a 10-15% gain.
