Mohnish Pabrai
Indian-American investor who extended value investing with the Dhandho low-risk high-return framework and clone investing strategy
Mohnish Pabrai (born 1964) is an Indian-American value investor and founder of Pabrai Investment Funds. His investment career began in 1999 when he founded the fund with $100,000 of his own money; by 2007 he was managing over $600 million in assets. He is a devoted follower of Buffett and Munger, known for the 'Dhandho Investment Framework' — derived from the business philosophy of Gujarati merchants from India, centered on 'low risk, high return, high certainty'. Pabrai's other important contribution is the systematic promotion of 'Clone Investing': discovering investment opportunities by analyzing the holdings of top value investors (13F filings). He also systematized Munger's checklist approach into The Checklist of an Investor. In 2007, Pabrai and Guy Spier won a lunch with Warren Buffett for $650,100 at charity auction; this lunch became an important turning point in his investment career. He also founded the Dakshana Foundation, funding education for impoverished students in India.

Beliefs and mental models
- Dhandho: Seek Low-Risk, High-Return, High-Certainty Investment Opportunities - Dhandho is Gujarati for 'endeavors that create wealth'. Pabrai distilled the business philosophy of Gujarati merchants into an investment framework: only invest in opportunities where 'heads I win, tails I don't lose much'. This requires buying at extremely low prices with extreme certainty, making downside risk minimal while upside potential is enormous.
- Clone Investing Top Investors Is the Most Underrated Investment Strategy - By analyzing the quarterly disclosed holdings (13F filings) of top value investors (Buffett, Munger, Seth Klarman, etc.), one can discover investment opportunities they have already deeply researched. Clone investing is not blind imitation, but buying the same securities at lower prices (due to the 45-day delay in 13F disclosure) after understanding their investment logic.
- Investment Checklists Are the Most Important Tool for Avoiding Elementary Mistakes - Influenced by Munger and Atul Gawande (author of The Checklist Manifesto), Pabrai believes the biggest losses in investing often come from preventable elementary mistakes, not complex unknown risks. A systematic investment checklist forces investors to check all known risk factors before each decision, significantly reducing error rates.
- Dhandho Investment Decision Framework - Screen investment opportunities with the asymmetric return standard of 'heads I win big, tails I lose little', only acting when certainty is extremely high and margin of safety is enormous.
- 13F Clone Investing System - Systematically analyze top value investors' quarterly 13F holding disclosures, then buy the same securities at lower prices using the 45-day delay after understanding their investment logic.
- Pre-Investment Checklist - Before making each investment decision, mandatorily check a list covering known risk factors to ensure no preventable mistakes are made through oversight.
