I was unable to analyze Berkshire Hathaway’s 13-F SEC filing in a timely manner over the past weekend and in the meantime a number of articles have appeared regarding changes in Berkshire’s portfolio for the quarter ended June 30, 2009.

Here are some links to articles analyzing Berkshire’s holdings at the end of June.  I have listed blog posts and other articles that go into more depth than the typical news stories that were reported over the weekend.  Keep in mind that most articles refer to Warren Buffett as the decision maker for all changes reported in the 13-F even though some of the smaller positions are managed by GEICO’s Lou Simpson.

• GuruFocus report on the latest 13-F includes sector weighting information along with a brief description of each position that was purchased, reduced, or eliminated.
• Bloomberg report containing information on Becton Dickinson holdings, a new purchase for Berkshire during the second quarter.  This article also provides a general overview regarding other position changes during the quarter.
• Dividend Growth Investor on Seeking Alpha reports on Berkshire’s portfolio and questions whether Warren Buffett is a “closet dividend investor”.   I don’t agree with the article’s ancillary points regarding Berkshire’s derivative positions, but the rest of the content is worthwhile.  I am not sure why so many normally astute investors have entirely misunderstood Berkshire’s dealings with derivatives, as I wrote about earlier this year.

It is clear that Berkshire Hathaway’s core holdings have dramatically appreciated over the past several months, including some appreciation that took place after the June 30 date on the last 13-F filing.  For my article on Berkshire Hathaway’s second quarter report, please click on this link.
