Agreed about the S&P, but it's small ($30m), I wonder if they acquired it somehow and haven't gotten rid of it yet. Seems contrary to everything they usually say and do.
As for Occidental, at $354m it may be #1 in the 13-F, but it's really small potatoes compared to the huge bond portfolio, the big private companies they own, notably Eurobank and Atlas/Poseidon (each about $2b). Even Thomas Cook is bigger (about $400m), and Mytilineos is about the same size as the Occidental bet. And of course, the dreaded Blackberry is even smaller, fading into obscurity (thankfully!)
