Buffett's shareholder letter: will always invest the vast majority of his money in stocks

Buffett issued his annual shareholder letter, noting that the value of his tradable stock holdings fell from $354 billion to $272 billion last year, but the value of his unlisted controlling stake has increased and remains well above the value of his tradable stock portfolio. We will always invest the vast majority of their money in equities - primarily US equities, although many of these companies will have significant international operations. Berkshire will never be more inclined to hold cash equivalents than to hold stakes in quality companies, whether controlling or partial.
