LEDA BRAGA

Braga was born in Brazil and earned a PhD in engineering from Imperial College London, where she lectured and led research for over three years. She then spent nearly seven years at JPMorgan as a quantitative analyst in derivatives research, modeling complex interest rate and equity products.

She had a stint at Cygnifi, a derivatives spinoff, before joining BlueCrest Capital Management in 2001. There she became President and Head of Systematic Trading, and in 2004 launched BlueTrend, a computer-driven managed futures fund.

BlueTrend grew into one of the industry's biggest systematic funds. In January 2015 she spun it out as her own firm, Systematica Investments, taking around $8.5 billion with her.

Systematica now manages roughly $12 billion across offices in London, Geneva, New York, Singapore, and beyond.

Braga runs systematic, computer-driven strategies. The flagship style is managed futures and trend following, which means her models spot price trends across markets and ride them, up or down.

The plain version is that rules and data decide the trades, not a human hunch on any given morning. She is a firm believer that this approach beats gut-feel trading over time.

Her funds trade across futures, currencies, and other markets globally, all driven by the same disciplined model rather than a star trader's mood.

Spinning out Systematica in 2015 was the bold move that defined her. She took BlueTrend, the systematic fund she built inside BlueCrest, and turned it into her own firm with roughly $8.5 billion, instantly becoming the most powerful woman running her own hedge fund shop.

The firm got off to a strong start and has since grown to about $12 billion. Building and then owning one of the largest systematic funds on earth is the achievement that made her name.

Trend-following is brilliant when markets trend and painful when they do not. Systematic managed-futures funds, including Braga's, have gone through stretches where choppy, directionless markets ate into returns and tested investors' patience.

The industry even coined algorithm aversion for the way clients flee models after a bad run. Braga's answer has been to defend the approach loudly and wait out the cycle.

The lesson is that a systematic edge demands the patience to sit through years that feel like nothing is working.

Braga's core belief is that investment management is really information management, and machines handle information better than people. She pushes back hard on the idea that a human trader has some magic insight a model lacks.

Her view is that the systematic approach will win over the long run, and she has said so plainly. She also believes discipline beats improvisation.

A rules-based system removes the panic and ego that wreck discretionary traders in bad markets.

Braga keeps her personal life private. She is Brazilian by birth and built her career in London.

Braga earned a PhD in engineering from Imperial College London, where she also lectured and ran research projects for more than three years before moving into finance. That hard-science and engineering training is the foundation of her entire model-driven style.

She thinks like an engineer building a machine, not a trader reading the tape.
