Value & Special Situations
Seth Klarman
Margin of safety as an absolute-return discipline; holding cash is a position.
Seth Klarman is a careful American value investor who ran a private fund and became famous for putting one goal above all others: don’t lose money. He buys things only when they cost far less than they are worth, and he is happy to hold lots of cash and wait for years when nothing is cheap enough. He wrote a famous, hard-to-find book called Margin of Safety that many investors treasure. His whole style is patient, cautious, and slow - study each business closely, and act only when the bargain is clear.
The method
First, work out honestly what a business is worth, then refuse to pay anywhere near it - buy only with a big margin of safety, a cushion that protects you if you are wrong or unlucky. He hunts for cheap businesses one at a time (bottom-up), ignoring big predictions about the whole market. When nothing is cheap enough, he simply holds cash and waits, saying ‘no’ far more often than ‘yes’. His goal is absolute - protect and grow real money - not to beat an index, and he treats real risk as permanent loss, not a bouncing price.
The record
Klarman built a long, respected record at a private American fund over several decades, known more for avoiding losses than for chasing the biggest gains. But this is old, US-based, private-fund history, built with patient money he was never forced to sell. Past results are not a promise; what worked for him in his time and place may not repeat, and none of it is a guide to what any person should do today.
Where they were wrong
Holding cash and waiting can mean missing years of a rising market, and being very cautious has a real cost - you can sit out gains while others make money. Deep-bargain hunting also needs huge skill, time, and patience that most people do not have: working out what a business is truly worth is slow, hard work, and a shallow look can turn a trap into a fake ‘bargain’. And patience can rot into never acting at all, out of fear rather than judgement.
