The book discusses Klarman's views about value investing, temperance, valuation, portfolio management, among other topics.

Klarman draws from the earlier investment book The Intelligent Investor, chapter 20, which is titled "Margin of Safety", a concept coined in the 1940s by authors Benjamin Graham and David Dodd.

"[1] In a 2017 interview with Charlie Rose, Klarman considered re-issuing a limited edition copy of Margin of Safety with proceeds going to charity but was otherwise not interested in reviving the book.

Within a matter of days, the non-authorized kindle edition of the book went to the #16 spot of "business and investment" section of the online bookstore.

"[4] Despite the initial flop, over time the book has achieved "cultlike" status amongst the value investing community and has been revered as a "bible" of sorts.
