In a shareholder letter dated Feb 2010, T2 Partners LLC, headed by Whitney Tilson and Glenn Tongue estimate the intrinsic value of BRK.A (Berkshire Hathaway) as $160,000. The share price is currently $127,400.
Value investors, of course, need no introduction to Warren Buffet's investment vehicle, Berkshire Hathaway. I am a British investor, and BRK.B shares are the only foreign shares I own directly (my OEICs will have some foreign shares in them, though). I had bought some in August of last year. I now regret not having bought more.
I was going to say that I really wish I had done was invested in 2000, when I began reading articles more extensively about Buffett, and his involvement with NetJets. I see that the share price is up about 84% over a decade, which is actually a bit shy of my own performance over the decade, to my surprise. Still, at least Buffett has the excuse of managing a business worth over $200bn; whereas my assets are, ahem, "more modest" than that.
