At the 2025 Berkshire Hathaway annual meeting, 94-year-old Warren Buffett announced the transition of the CEO position to Greg Abel, as shareholders stood to express their gratitude for Buffett's 60 years of contributions. Under his leadership, Berkshire's Class A shares rose from $19 to $809,000.

Buffett places great emphasis on corporate financial statements. He does not simply review reports; he identifies uncertainties and engages in deep discussions with those who provide the data. This meticulousness has made his investment approach remarkably successful. Through his experiences, Buffett has established four key investment principles:

• Vigilant Leadership: Businesses must be led by responsible management teams.
• Long-Term Outlook: Prefer companies with sustainable competitive advantages.
• Stability: Prioritize steady free cash flow.
• Buy at a Discount: Ensure that there is sufficient discrepancy between intrinsic value and market price.

These principles apply not only to Buffett but can also assist various investors in finding the right direction in the stock market.
