The Sage of Omaha

There's an interesting interview with Warren Buffet on CNN by Nicholas Varchaver. Here are some highlights:

On why the financial crunch is so murky and it is so difficult for banks to report their lossses:

Q: Do you find it striking that banks keep looking into their investments and not knowing what they have?

A: I read a few prospectuses for residential-mortgage-backed securities - mortgages, thousands of mortgages backing them, and then those all tranched into maybe 30 slices. You create a CDO by taking one of the lower tranches of that one and 50 others like it. Now if you're going to understand that CDO, you've got 50-times-300 pages to read, it's 15,000. If you take one of the lower tranches of the CDO and take 50 of those and create a CDO squared, you're now up to 750,000 pages to read to understand one security. I mean, it can't be done. When you start buying tranches of other instruments, nobody knows what the hell they're doing. It's ridiculous. And of course, you took a lower tranche of a mortgage-backed security and did 100 of those and thought you were diversifying risk. Hell, they're all subject to the same thing. I mean, it may be a little different whether they're in California or Nebraska, but the idea that this is uncorrelated risk and therefore you can take the CDO and call the top 50% of it super-senior - it isn't super-senior or anything. It's a bunch of juniors all put together. And the juniors all correlate.

Here Warren Buffet gives the best example of why the "efficient market" hypothesis is simply not true:

It may have some meaning to you if you're still being taught efficient-market theory, which was standard procedure 25 years ago. But we've had a recent illustration of why the theory is misguided. In the past seven or eight or nine weeks, Berkshire has built up a position in auction-rate securities [bonds whose interest rates are periodically reset at auction...] of about $4 billion. And what we have seen there is really quite phenomenal. Every day we get bid lists. The fascinating thing is that on these bid lists, frequently the same credit will appear more than once.

Here's one from yesterday. We bid on this particular issue - this happens to be Citizens Insurance, which is a creature of the state of Florida. It was set up to take care of hurricane insurance, and it's backed by premium taxes, and if they have a big hurricane and the fund becomes inadequate, they raise the premium taxes. There's nothing wrong with the credit. So we bid on three different Citizens securities that day. We got one bid at an 11.33% interest rate. One that we didn't buy went for 9.87%, and one went for 6.0%. It's the same bond, the same time, the same dealer. And a big issue. This is not some little anomaly, as they like to say in academic circles every time they find something that disagrees with their theory.

And here is the very best investing advice that any amount of money can buy:

Q: What should we say to investors now?

A: The answer is you don't want investors to think that what they read today is important in terms of their investment strategy. Their investment strategy should factor in that (a) if you knew what was going to happen in the economy, you still wouldn't necessarily know what was going to happen in the stock market. And (b) they can't pick stocks that are better than average. Stocks are a good thing to own over time. There's only two things you can do wrong: You can buy the wrong ones, and you can buy or sell them at the wrong time. And the truth is you never need to sell them, basically. But they could buy a cross section of American industry, and if a cross section of American industry doesn't work, certainly trying to pick the little beauties here and there isn't going to work either. Then they just have to worry about getting greedy. You know, I always say you should get greedy when others are fearful and fearful when others are greedy. But that's too much to expect. Of course, you shouldn't get greedy when others get greedy and fearful when others get fearful. At a minimum, try to stay away from that.
