Lessons learned from JRCC

My recent JRCC trades are so sick that I ruined my trading mood. Stopped my growing UP momentum in the past 2 weeks.

The mistake started from average down loss of 400 short position of JRCC on Mar 22(Wednesday) when my balance appoache $49700. If I cut loss then, my loss would just be $300, and I would not have so much trouble.

Where is JRCC from? I never heard from it before I try my portfolio test. My short creteria picked JRCC which met with my understanding of bad (or down turn) stock.
