First Buffett shareholder letter after Munger's death. It opens with Munger as the architect of Berkshire and Buffett himself more as a general contractor; then returns to long-term holdings, insurance, energy, cash and avoiding Wall Street noise.
Key points
- The heart of the letter is not the tribute itself, but the explanation of how Munger moved Buffett from a cheap bad business to a great business at a fair price.
- Buffett continues to caution shareholders to ignore accounting noise from short-term GAAP net income fluctuations, particularly changes in public stock market capitalization.
- He emphasized that Berkshire's size is already very large, and the future excess return space cannot be as exaggerated as in the early days; this is important for investors to understand BRK.B's expectations.
- Insurance, BNSF, Berkshire Hathaway Energy and public stock portfolios are looked at in different risk cycles and cannot be judged by just one quarter's profit.
- The letter's caution against Wall Street forecasts, frequent trading, and short-term advisory advice continued the educational function of Buffett's letters to long-term shareholders.
