Sell Signal for MEDX

My trading system has flagged MEDX as a short candidate. Sell Short 800 shares of MEDX at the open on Dec-16 with stop-loss set 10% higher than the entry price. Let's see if I have better luck with MEDX than with ABGX. Yesterday with Abgenix it did feel like a kick in the nuts but, psychologically, I seem to be over my loss today. My ABGX position got closed at the open because it blew through my stop loss. Medarex and Abgenix are both developing antibodies to treat cancer but I just can't see myself so unlucky as to witness BMY or some other company buying MEDX while I am shorting it. Of course, MEDX could be bought but not at this juncture. MEDX is technically weak and this is what counts for the short-term trade. I limit my exposure to ~10% of my account in case the stock does move against me.
