## Core Philosophy
Graham's investment style was defensive, specifically seeking out quality at a good price. [Source: https://www.fool.com/investing/how-to-invest/famous-investors/benjamin-graham/] He distilled the secret of sound investment into the motto, "Margin of Safety." [Source: https://quotefancy.com/quote/1559578/Benjamin-Graham-Confronted-with-a-challenge-to-distill-the-secret-of-sound-investment] He defined the field by stating: "An investment operation is one which, upon thorough analysis, promises safety of principal and an adequate return. Operations not meeting these requirements are speculative." [Source: https://www.cabotwealth.com/daily/value-stocks/benjamin-graham-quotes-to-improve-your-investing-results] He distinguished investors from speculators, holding that "a stock is not just a ticker symbol or an electronic blip; it is an ownership interest in an actual business, with an underlying value that does not depend on its share price," and that "people who invest make money for themselves; people who speculate make money for their brokers." [Source: https://www.cabotwealth.com/daily/value-stocks/benjamin-graham-quotes-to-improve-your-investing-results] His maxims included "Buy not on optimism, but on arithmetic" and "The most brilliant financial strategy consists of living well within one's means." [Source: https://beyondbengraham.com/about-ben-graham/] In his 1976 Financial Analysts Journal interview, Graham said: "I am no longer an advocate of elaborate techniques of security analysis in order to find superior value opportunities," explaining he had lost most of his interest in the details of security analysis and believed it could be done successfully with a few techniques and simple principles.

## Decision-Making Patterns
Graham experienced two of the worst stock market crashes in history in 1907 and 1929, and his investment style was defensive. [Source: https://www.fool.com/investing/how-to-invest/famous-investors/benjamin-graham/] He counseled buying "not on optimism, but on arithmetic." [Source: https://beyondbengraham.com/about-ben-graham/] He held that "the intelligent investor is a realist who sells to optimists and buys from pessimists," and that "even the intelligent investor is likely to need considerable willpower to keep from following the crowd." [Source: https://www.cabotwealth.com/daily/value-stocks/benjamin-graham-quotes-to-improve-your-investing-results] He advised patience, noting that "as long as the earning power of his holdings remains satisfactory, he can give as little attention as he pleases to the vagaries of the stock market." [Source: https://www.kingswell.io/p/chapter-8-of-the-intelligent-investor] Late in life, he advocated "the group approach. To try to buy groups of stocks that meet some simple criterion for being undervalued-regardless of the industry," and observed that "if I have noticed anything over these 60 years on Wall Street, it is that people do not succeed in forecasting what's going to happen to the stock market."

## Mental Models
Graham introduced the Mr. Market parable: "Imagine that in some private business you own a small share that cost you $1,000. One of your partners, named Mr. Market, is very obliging indeed. Every day he tells you what he thinks your interest is worth and furthermore offers either to buy you out or to sell you an additional interest on that basis." [Source: https://www.kingswell.io/p/chapter-8-of-the-intelligent-investor] He viewed a stock as "an ownership interest in an actual business, with an underlying value that does not depend on its share price."
