Not in case of Mastercard vs Visa. I picked Visa, and Mastercard has outperformed Visa by close to 20%.
I bought a share of Berkshire Class B. It is underperforming the market this year, which is strange considering the bear case on Berkshire is around the index put options that Buffet sold at market peak in 2007. I would have expected higher beta here.
Now I own both Microsoft and Berkshire :) WSJ had a pretty positive article on Microsoft today.
