价值投资，在历史上经历过哪些演变？｜投资小知识

Group 1 - The core investment philosophy of Graham focused on finding extremely undervalued companies with easily liquidated assets [2][4] - Post-World War II, the investment landscape shifted towards low valuation investments, with overall market valuations increasing due to the baby boom and the "Nifty Fifty" bull market [4][5] - The concept of "cigar butt" investing, which involved picking up undervalued opportunities, became less prevalent as the market evolved [5] Group 2 - Graham's disciple Schloss specialized in low price-to-book ratio investments, which later influenced the development of value indices in index funds [6][7] - Buffett, influenced by Charlie Munger, began to accept the idea of buying excellent companies at reasonable prices, diverging from Graham's strict undervaluation approach [8][9] - Munger's perspective emphasized that purchasing high-quality companies at reasonable prices can still be a sound investment, as the value created by these companies will exceed the initial price paid [9]
