I think Berkshire has lost a lot of its luster. Its performance over 1, 3 and 5 years is only slightly better than VTSAX.... for 10 years it is a little better... of course for longer periods BRK.A is the clear winner but its recent history has been just ok.
I agree and that's likely to continue for a while. However, Berkshire's volatility is below average with a Beta of .87 so on risk adjusted basis just keeping up with the market is a win.
Berkshire is the ultimate defensive stock. As I talked about during my post about it during the recession, it has a bunch of very stable business offering everything from auto insurances, to rail transportation, too fast food, and bricks and paint. They are likely to suffer less in in recession (which is what happened).
Meanwhile, Warren's reputation gave him access to some incredible deals, his investments in GE, Goldman Sachs, and BofA were all amazing deals. First, because Berkshire was one of the few companies that had $5 and $10 billion in cash and second because investment by Warren Buffett means something. Meaning that if I had spare $10 billion lying around BofA was willing to give Buffett better terms on his investment than I'd would have gotten.
There are plenty of better stocks (or just the total market index fund) that are likely to do better than Berkshire in a bull market, few better in a bear.
