The strategy we've adopted precludes our following standard diversification dogma. Many pundits would therefore say the strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.
Warren BuffettThat would be nice if [people] stuck [treasury bills] all under a mattress, but they got to buy something with them. Sometimes they buy a treasury note, sometimes they set up sovereign wealth funds. They can do all kinds of things. They can buy our companies here. As long as we consume more than we produce, and we trade away little pieces of the country daily, they're going to own something. Now, they can't run from American assets. I mean every day the rest of the world is going to have about two billion more of American assets than we have, as long as they sell us these goods.
Warren BuffettAt age 19, I read a book [The Intelligent Investor] and what I'm doing today, at age 76, is running things through the same thought process I learned from the book I read at 19.
