Why HN recommends it

Investing book built around a set of core principles on risk, market cycles and value, often named alongside Graham; suited to investors who want a framework for thinking about markets rather than specific tactics.

Summarised by Claude from recommending comments

This book explains the keys to successful investment and the pitfalls that can destroy capital or ruin a career. Utilizing passages from his memos to illustrate his ideas, Marks teaches by example, detailing the development of an investment philosophy that fully acknowledges the complexities of investing and the perils of the financial world. Brilliantly applying insight to today's volatile markets, Marks offers a volume that is part memoir, part creed, with a number of broad takeaways.
