Depends. Only if I have to. Not afraid to use margin. That's what it's there for, but must be careful. Certain stocks I will use it, ie., stocks I am very familiar with trading. My favorite traders you already know: CRUS, BBRY, BTU, ANR, FSLR, SPWR-all to the short side. Very rarely do I go long these stocks. CRUS once in awhile when it is way oversold. Went long BBRY on the Friday dump and payed for it. Never again. I tend to trade the same stocks over & over, instead of jumping around. I am comfortable with the stocks I trade. I know their patterns and how they act. Even on 100 point up day, not afraid to short. Looking for market reversal by Thursday, and might buy DGAZ Thursday if there is a big draw number. Market closed Friday.
