Who is Howard Marks?

Born in 1946 in Los Angeles, California, Howard Marks developed an interest in finance at an early age. After graduating from the University of Pennsylvania’s Wharton School, Marks began his career in finance as an equity research analyst. In 1995, he co-founded Oaktree Capital Management, which has since become one of the world’s leading investment management firms.

The Oaktree Capital Story

Under Marks’ leadership, Oaktree Capital has grown into a global powerhouse, managing over $220 billion in assets, which is a testament to the firm’s exceptional investment strategies and long-term approach.

Oaktree in 2026

The Oaktree story took its biggest turn in August 2026, when Brookfield completed its acquisition of the firm, ending a partnership that began in 2019. The combined credit platform now runs about $365 billion. Marks stayed on as Co-Chair of Oaktree, joined the Brookfield Corporation board, and chairs Brookfield’s Investment Solutions Group. Oaktree’s co-CEOs, Bob O’Leary and Armen Panossian, now run Brookfield’s credit business as well.

For all the corporate reshuffling, the investment philosophy has not changed. Oaktree is still a contrarian credit shop built on Marks’ obsession with risk, and the memos below are still where that thinking shows up first.

Key Takeaways from Marks’ Philosophy

1. The Importance of Risk Management: Marks stresses that risk management is the key to long-term success in investing. He advocates for a cautious approach, emphasizing the need to balance potential returns with potential losses.
2. The Power of Contrarian Thinking: Marks is known for his willingness to challenge conventional wisdom and take unpopular positions. He encourages investors to think independently and avoid the herd mentality.
3. The Value of Patience: In an era of instant gratification, Marks reminds us that investing is a long-term game. He advocates for a patient approach, encouraging investors to focus on steady, incremental progress rather than quick gains.
4. The Dangers of Emotional Decision-Making: Marks warns against the dangers of emotional decision-making, emphasizing the need for a rational, data-driven approach to investing.
5. The Importance of Margin of Safety: Marks stresses the importance of building a margin of safety into investment decisions, ensuring that there’s a sufficient buffer to absorb potential losses.

Books by Marks

The Most Important Thing: Marks’ 2011 book is a must-read for any serious investor. In it, he distills his investment philosophy into 20 key principles.

Mastering the Market Cycle: Marks’ 2018 book offers a comprehensive guide to understanding market cycles and making informed investment decisions.

The Memo Habit

Since 1990, Marks has written client memos that became some of the most forwarded documents in finance. They are plainspoken letters about risk, cycles, and investor psychology, written in plain English and free of jargon. Warren Buffett has said he reads them the moment they arrive. The two books above grew directly out of that habit: The Most Important Thing distills two decades of memos into twenty principles, and Mastering the Market Cycle is the memo habit applied to the single subject Marks thinks matters most.

If you want to go deeper on Oaktree itself, the site’s glossary post on Oaktree Capital Management covers the firm’s history, and the book review of The Most Important Thing walks through the book chapter by chapter.
