AI summary
The video explains that, in long-term investing, investors should examine structures for avoiding losses and the quality of businesses before focusing on returns. Its core reasoning is as follows. ① SK Hynix, Samsung, and Micron lead the AI and memory industries, and long-term contracts may lock in revenue and profitability for several years. However, rather than trying to manage the detailed variables of complex industries, individual investors can use Berkshire Hathaway Class B like an index. ② Although the S&P 500 has an excellent long-term average, returns can stagnate for 10~30 years depending on overvaluation and undervaluation, so investors should remain open to the possibility of average annual returns of -2%~+2% over 10 years starting in 2026. ③ The central investment checklist consists of avoiding excessive leverage, assessing moats that provide sustainable competitive advantages, and evaluating the quality of owners and management. Decisions should be based on business value rather than following trends and crowds. ④ If investors buy an excellent business on the rare occasion when it is significantly undervalued, it is important to hold it until evidence of permanent impairment appears, rather than reacting to temporary declines. Selling an excellent business simply because it has reached fair value may become their greatest regret.
