Vivian--Terrific explanation of Alpha and Beta.  I learned some new things from your tutorial.  Also, the worm is turning for me. I made a whopping 2.6% on my portfolio in 2014 (which is 52% stocks and 48% fixed income).  This year in the first quarter, I'm on a 14% annual return track, with things looking better every day.
