๐Ÿ“– Biography

Seth Klarman is the anti-celebrity hedge fund manager. He doesn't do CNBC appearances. He doesn't tweet. He barely does interviews. His book 'Margin of Safety' has been out of print since 1991 and sells for $1,500+ on eBay because he refuses to reprint it. Yet Baupost Group, which he's run since 1982, has compounded at ~20% annually for 40+ years. His secret is extreme patience โ€” Baupost regularly holds 30-50% of the portfolio in cash, waiting for opportunities that most managers would never have the discipline to wait for. When markets crash, Klarman has the cash to go shopping while everyone else is forced to sell. He's arguably the most disciplined investor alive.

โšก Author of 'Margin of Safety' โ€” sells for $1,500+ used because it's out of printโšก Keeping 30-50% of Baupost in CASH โ€” always ready for dislocationsโšก Never advertising, never doing media, never speaking publiclyโšก Returning capital to investors when he can't find opportunities
Investment Philosophy

โ€œMargin of safety isn't just a concept โ€” it's a way of life. Hold cash when nothing is cheap. Be greedy when others are fearful. The hardest thing in investing is doing nothing.โ€

๐Ÿ† Greatest Trade

2008-2009 โ€” deployed $4B in cash during the financial crisis

Bought distressed assets at pennies on the dollar. Baupost returned 27% in 2009.

๐Ÿ’€ Worst Trade

Persistent cash drag โ€” holding 30-50% in cash during bull markets

Underperforms in strong bull markets. But preserves capital perfectly in downturns.

๐Ÿ’ฌ Famous Quotes

โ€œThe stock market is the story of cycles and of the human behavior that is responsible for overreactions in both directions.โ€

โ€œValue investing is at its core the marriage of a contrarian streak and a calculator.โ€

โ€œInvesting is the intersection of economics and psychology.โ€
