Howard Marks is the co-founder and co-chairman of Oaktree Capital Management, a Los Angeles–based distressed-debt and alternative-investment firm. His standing in the investment world rests less on any single trade than on a body of client memos he has written since 1990 — 167 of them through 2026, collected in the corpus that grounds this wiki. Marks frames these memos as falling into two categories: those that set out "the enduring truths of investing" and those that chronicle the major financial events of the era.

Marks joined the investment industry at the tail end of the 1960s, and was educated at the University of Chicago, where he absorbed the then-emerging Capital Market Theory. He attributes much of his early framework to that exposure — particularly the notion that returns must be judged against the risk taken to achieve them, which became the idea of risk-adjusted returns. He read Benjamin Graham and David L. Dodd's security-analysis at Wharton, describing it as "the bible of value investing," in the edition edited by Sidney Cottle.

His most durable contributions are a set of named ideas that recur across the memos and coalesced into his 2011 book The Most Important Thing. The book's first chapter, written for Columbia Business School Publishing after warren-buffett promised him a jacket blurb, introduces what Marks calls second-level thinking — a topic he says he "never covered it explicitly for the readers of my memos" before returning to it in 2015. See second-level-thinking.

Three of Marks's recurring convictions define his intellectual signature. First, that risk is not volatility but the probability and magnitude of loss, and that the conventional "Riskier investments provide higher returns" slogan is false — higher expected returns only sometimes arrive, accompanied by greater uncertainty or actual risk of loss. See risk-vs-uncertainty. Second, that cycles are "inevitable, often profound, and the most reliable feature of the business and investment worlds", driven by the pendulum of investor psychology swinging between euphoria and depression. See cycles. Third, that the future is largely unknowable — a theme he returns to in memos titled Uncertainty, The Illusion of Knowledge, and The Folly of Certainty — so the investor's job is not to predict but to prepare.

Marks positions himself as a student of market history. His January 2000 memo bubble.com opens with Edward Chancellor's chronicle of the 1720 South Sea Bubble and Sir Isaac Newton's double loss — selling early, then buying back at the top — to argue that even the smartest actors are not immune to speculative mania. This grounding in prior episodes feeds his contrarian temperament: his memos repeatedly counsel moving against the crowd precisely when doing so feels most uncomfortable, as in Dare to Be Great and its 2014 sequel, where he argues that superior results require being different and better, not merely right.

In style, Marks is closer to benjamin-graham than to warren-buffett in emphasis: he writes about risk control, the avoidance of losers, and the insistence on a margin of safety more than about finding great businesses. He has described his own lineage directly — "everything you know about investing came from other people. Benjamin Graham taught you about margin of safety. Buffett taught you about quality. Charlie Munger taught you about mental models from multiple disciplines." See margin-of-safety.
