Strongly bullish on China as the most exciting global investment market, citing its strategic focus and undervalued public markets.

Skeptical of the current state of hedge funds, viewing them as a fee structure rather than a strategy and predicting an industry shakeout.
Believes the primary responsibility of a public company is to maximize shareholder value, aligning with Milton Friedman's philosophy.
Views the Obama-era auto industry bailout as a successful financial restructuring, enabled by the authority granted through TARP funds.
2008
Willett Advisors was established to manage Michael Bloomberg's assets, benefiting from a 'clean balance sheet' without the legacy illiquid portfolios that burdened other institutions at the time.
Obama Administration
Served in the Obama administration, leading the restructuring of the U.S. automobile industry. He viewed the task as a financial restructuring, enabled by TARP funds, and identified dealing with auto finance companies as the biggest challenge.
Post-2008
Focused on building Willett Advisors' portfolio, finding that establishing a quality venture capital allocation was the 'most challenging area' due to difficulty in accessing top managers.
Present
Expresses a strong conviction that China is the most exciting and undervalued major investment market, while being underweight Europe and predicting a 'shakeout' in the hedge fund industry.
▶Willett Advisors' Investment DoctrineApr 2026
Rattner outlines a clear investment philosophy for Willett Advisors, rooted in the endowment model pioneered by David Swenson. This involves a strong belief in long-term equity beta, a concentrated approach to manager selection to avoid mean reversion, and a significant direct investment program in private assets to reduce fee drag.
This strategy reveals a focus on structural advantages (beta, lower fees) and high-conviction bets rather than attempting to generate alpha through broad diversification, which Rattner believes is counterproductive.
▶The China ConvictionApr 2026
Rattner expresses a highly bullish and controversial view on China, identifying it as the world's most exciting and cheapest major investment market relative to its growth. He respects China's ability to execute long-term strategic plans like 'Made in China 2025' and believes it will outperform India economically.
Rattner's focus on China's economic fundamentals and strategic execution appears to override geopolitical concerns, suggesting a pragmatic, numbers-driven approach to international investing.
▶Skepticism of Overhyped Asset Classes
Rattner expresses significant skepticism towards several areas of the market. He views hedge funds as a 'fee structure' and predicts an industry shakeout, believes the private equity sector holds too much 'dry powder,' and finds building a top-tier venture capital portfolio exceptionally challenging.
This skepticism indicates a belief that manager selection and avoiding crowded trades are critical, as high fees and excess capital can erode the theoretical premiums of alternative assets.
▶Government Intervention and Corporate PurposeApr 2026
Drawing from his experience restructuring the auto industry, Rattner details the practicalities of government intervention, emphasizing its nature as a financial, not operational, task enabled by TARP. He also holds a classic Milton Friedman view on corporate governance, stating a company's primary duty is to its shareholders.
Rattner's perspective is that of a financial professional applied to public policy, prioritizing financial viability and shareholder returns as the core objectives for both government bailouts and corporate management.
