Although I don't have a precise means to calculate across all my accounts, that figure seems about right for me to. I am guessing 7% too. EPZM made a big difference, as well as PCYC. No big losers yet, fingers crossed.
Best start of the year I can recall. I'm heavy banks and biotech this year. I don't know how long I'll stay this way, but its been the winning formula so far.
