Colm O'Shea is the founder, Chief Investment Officer, and sole portfolio manager for the Global Macro fund. He built the firm after serving as a macro prop trader at Citigroup and later as a portfolio manager at Soros Fund Management under Stanley Druckenmiller. All investment decisions, risk sizing, and portfolio construction trace back to O'Shea. There is no published deputy CIO or named successor. ### What is Flatiron's core investment strategy? Flatiron runs a discretionary global-macro strategy. O'Shea trades across four main arenas: currencies, interest rates, commodities, and equity indices. He establishes both directional positions and cross-market relative-value trades. The process is fundamentally driven by his reading of central-bank policy, global capital flows, and macroeconomic regime shifts. This is not a systematic or algorithmic operation. ### Does Flatiron accept external capital? Flatiron has historically operated as a classic hedge fund, raising capital from institutional allocators, family offices, and funds of funds. The flagship vehicle was open to qualified external investors. However, given that AUM has shrunk significantly from its peak, it is not clear whether the firm is actively soliciting new mandates or operating closer to a concentrated managed account for a small group of existing investors. ### How did Colm O'Shea's experience at Soros Fund Management shape Flatiron? O'Shea worked directly under Stanley Druckenmiller from 2003 to 2005, a period widely considered a masterclass in high-conviction macro speculation. From Druckenmiller, he absorbed the practice of sizing positions aggressively only when the trade, the timing, and the macro backdrop all align. O'Shea has publicly credited that apprenticeship for his willingness to concentrate risk — and to sit in cash during periods where he lacks high-conviction views. ### What is Flatiron's track record of performance? Flatiron's flagship fund launched in 2008 and performed strongly during periods of macro volatility, including the post-financial-crisis recovery and the 2011 European sovereign-debt crisis. It endured a difficult stretch during the low-rate, low-volatility years driven by quantitative easing, which compressed returns for many discretionary macro managers. The fund regained attention with a strong 2024 as currency and rates volatility returned. ### Where is Flatiron based and does it have other offices? Flatiron operates from New York, with no disclosed satellite offices overseas. The firm has historically been a lean operation, reflecting O'Shea's preference for maintaining trading infrastructure directly around the investment team rather than building a global multi-office platform. ### How is Flatiron's macro strategy different from a multi-manager platform like Citadel or Millennium? Flatiron is not a multi-manager platform. It runs a single book managed by one CIO with no pod structure, no siloed sector heads, and no central risk overlays imposed by a separate risk committee. This concentrates key-person risk but also eliminates the internal correlation and crowding that can appear in multi-manager macro platforms. Performance is undiluted, single-writer macro. ## Related profiles - [Petrus Advisers Bratislava](https://altss.com/profile/petrus-advisers-bratislava-ks) - [Stone Fortress Wealth Strategies](https://altss.com/profile/stone-fortress-wealth-strategies) --- Last updated: 2026-06-03T20:00:00.000Z Canonical page: https://altss.com/profile/flatiron-fund-management-lp Maintained by Altss — https://altss.com — methodology: https://altss.com/methodology
