Fun with 13Fs…

I don’t tend to pay much attention to 13Fs, the institutional holdings reports that hedge funds and other large investors are required to file 45 days after the close of the quarter, mostly because there’s only so many filings that my dog — the brain behind — is willing to read. Besides, the folks at Insider Score already do a great job at covering these filings, as well as other types of insider filings.

But because yesterday marked 45 days, I decided to take a break from the usual filings to take a quick skim of some 13Fs. One that caught my attention was this one filed by the Bill and Melinda Gates Foundation, which showed a big increase in its stake in IAC Corp. (IACI) and some growing interest in a few non-Blue Chips, like Ansys (ANSS) and Autonation (AN). During the quarter, the value of the Foundation’s stock holdings declined a little over 7%, which was slightly better than the S&P.

Of course, what would have made this really interesting is if the Foundation had disclosed a stake in Yahoo (YHOO) or, even more interesting, Apple (AAPL). But that’s just wishful thinking on my part.

Also interesting was the 13F filed by Yale University’s David Swensen, who judging by that 13F likes Ishares these days. According to the filing, Swensen’s group bought a lot of this during the quarter, going from zero to nearly $22 million and nearly doubling his stake in the Ishares EAFE Index Fund.
