Intech’s management team has acquired the company from Janus Henderson, resulting in a private, fully independent company. Intech is 100% owned by the company’s founder, employees, and board members. Our full independence increases alignment with clients and provides additional flexibility to deliver enhanced value for clients, partners, employees, and all stakeholders. Intech employees pride themselves on maintaining a highly ethical, integrity-first culture that builds honest and constructive relationships with clients. 


Global Investment Solutions

With over 50% of assets from clients domiciled outside the U.S., Intech has truly global investment platforms differing by relative or absolute risk objectives. We can calibrate our solutions to fit geographic regions, return objectives, risk budgets, or sustainability goals. Indeed, over half of Intech’s AUM are in bespoke portfolios.



Sustainability Commitment

Intech believes that environmental, social, and governance (ESG) factors are important drivers of portfolio risk. As such, we consider their portfolio integration consistent with our principal responsibility: representing our clients’ objectives and best interests. Across our investment platforms, we also support client preferences to increase the impact of their investments.

Our Founder


Fernholz-finalOur founder, E. Robert Fernholz, PhD, served as Intech’s Chief Investment Officer from 1987-2011 and has subsequently been a consultant for the firm. He was born in 1941 in New Jersey. His father was a distinguished German chemist who fled Germany and immigrated to the U.S. in 1935 to join the faculty of Princeton University. Dr. Fernholz’s mother, Mary Briganti Fernholz, was the daughter of Italian Immigrants who came to the U.S. in the early 1900s. She held an M.S. degree in Economics from Smith College and worked at Princeton University as a research assistant in the Economics Department.

Growing up in Princeton and attending Princeton Country Day School, Dr. Fernholz graduated high school at Deerfield Academy in Massachusetts in 1958. He majored in mathematics at Princeton University, under the direction of William Feller, and received his BA degree magna cum laude in 1962. He earned his PhD in mathematics at Columbia University in 1967, writing his thesis under the direction of Lipman Bers.

Dr. Fernholz began his career as an academic mathematician at the University of Washington and later held various professorships at City University of New York, Universidad Nacional de Buenos Aires, and Princeton University. Fernholz left Princeton University in 1980 to become Research Director at Arbitrage Management Company. He also worked at Brignoli Models, where he worked alongside Dr. Harry Markowitz.

SPT Book CoverIn 1987, Dr. Fernholz founded Intech, basing our mathematical investment process on a 1982 paper he published, “Stochastic Portfolio Theory and Stochastic Market Equilibrium.” He later elaborated on these mathematical methods in his monograph, Stochastic Portfolio Theory (Springer 2002). Dr. Fernholz is also the author of numerous research articles both in pure and applied mathematics as well as statistics and mathematics of finance.
