Here is a Berkshire Hathaway portfolio tracker if anyone is interested:

Berkshire also sold around $2.8B of Apple stock, although that was a much smaller move as a percentage of their position.
So 60% of this portfolio is in just 4 stocks? Apple, American Express, BofA, and Chevron. Didn't expect that.
