Harold de Boer

Managing Director, Head of R&D

Transtrend

Harold is the architect of Transtrend’s Diversified Trend Program, responsible for R&D, portfolio management and trading. Harold was born and raised on a dairy farm in Drenthe. And from a young age, he has been intrigued by linking mathematics to the real world around us.

He graduated in 1990 with a Masterโ€™s degree in Applied Mathematics from the University of Twente in the Netherlands. In the final phase of his studies, while working on the project that would later become Transtrend, he became fascinated by the concept of leptokurtosis โ€” or โ€˜fat tailsโ€™ โ€” in probability distributions, a topic which has inspired him throughout his career.  

Haroldโ€™s approach to markets is best described as a combination of a farmerโ€™s common sense and mathematics, never losing sight of the underlying fundamentals.
