Howard Marks is an American investor and writer who co-founded Oaktree Capital Management in 1995 and remains its co-chairman. Before Oaktree, he worked in equity research and debt investing at Citicorp, then led high-yield and convertible investing at TCW. High-yield debt pays more interest because repayment is less certain. Convertible securities can be exchanged for company shares. Marks and Bruce Karsh also organized an early distressed-debt fund at TCW. Distressed debt comes from borrowers in serious financial trouble and is often bought at a steep discount. Oaktree built its name in that field and other forms of credit investing, which means investing in loans and debt securities. Marks is known for his public investment memos, The Most Important Thing, and Mastering the Market Cycle. His approach centers on risk control, investor psychology, and judging where markets stand in a cycle, with greater emphasis on limiting losses than chasing spectacular gains. This page is not Howard Marks's personal portfolio. It shows Oaktree Capital Management LP's quarterly Form 13F report, a United States regulatory filing for certain US-listed shares and related securities that the firm holds. Use the current-holdings and quarterly-change sections to inspect the reported positions. The filing does not cover every Oaktree fund, credit strategy, private investment, debt holding, short position, derivative contract tied to another asset, or client account.

Howard Marks is an American investor and writer. He co-founded Oaktree Capital Management in 1995 and remains its co-chairman.
Oaktree is an investment manager founded by Marks, Bruce Karsh, and three other partners after they left TCW. It became known for high-yield debt, distressed debt, and private equity, which means investing in companies outside public stock markets. High-yield debt pays more interest because the borrower is more likely to miss payments or fail to repay.
Yes. Marks remains Oaktree's co-chairman as well as a co-founder.
Marks publishes essays called memos about investment strategy and the economy. They are widely read for his views on risk, investor psychology, and market cycles.
His investing books include The Most Important Thing, The Most Important Thing Illuminated, and Mastering the Market Cycle.
He is closely associated with credit investing and distressed debt, which is debt from a borrower in serious financial trouble. His approach stresses risk control, careful reading of market psychology, and judging the current stage of a market cycle.
Brookfield Asset Management acquired 62 percent of Oaktree in 2019. Marks and other Oaktree members retained the remaining 38 percent and control of day-to-day operations.
No. The current-holdings and quarterly-change sections show positions reported by Oaktree Capital Management LP, not Marks's personal brokerage account.
No. Form 13F is a United States regulatory filing for certain US-listed shares and related securities that a manager holds. Oaktree's credit funds, private investments, debt holdings, short positions, many derivative contracts tied to other assets, and other assets or accounts can sit outside that report.
No. The filing reports a quarter-end snapshot only after the quarter has finished, so positions may have changed before readers see it. It also leaves out much of Oaktree's credit business. The page is useful for studying disclosed holdings and quarterly changes, not as a live trade feed.
