Core Insights - Jeremy Miller, a long-term shareholder of Berkshire Hathaway, has studied Warren Buffett's annual letters to shareholders since the 1960s, treating them as an "investment textbook" and has authored a book detailing his findings on Buffett's investment philosophy [1] Group 1: Investment Principles - Principle One: Never Predict the Market Buffett has stated that he does not possess the ability to predict market trends and dismisses those who claim to do so, especially after market movements have occurred [3][5][4] - Principle Two: Invest in "Deep Value" Buffett focuses on "deep value," which refers to companies with strong products and management that are undervalued by the market. He compares a company's actual assets to its market valuation and invests when he identifies a significant undervaluation [6][7] - Principle Three: Take a Long-Term View Buffett emphasizes that short-term results are not a priority, advocating for a minimum five-year performance review of a company. He believes that time can heal poor investments and that successful companies will continue to provide opportunities for reinvestment [12][13] - Principle Four: Relative Performance Matters Buffett asserts that performance should be evaluated relative to appropriate benchmarks, such as major stock indices. He uses these comparisons to assess his investment success or failure [14][15] - Principle Five: The Power of Compounding Buffett highlights the importance of compound returns, illustrating how small variables can lead to significant changes over time, while also cautioning against overlooked costs and taxes that can erode wealth [16]
