Neil Chriss

Neil Chriss holds a PhD in mathematics from the University of Chicago. He worked at Goldman Sachs in the quantitative strategies group and later at SAC Capital before co-founding Hutchin Hill Capital, a multi-strategy hedge fund that managed approximately $1.5 billion at peak. He is best known as co-developer of the Almgren-Chriss optimal execution model, which provides a rigorous mathematical framework for minimising the market impact costs of large equity trades. The model treats optimal execution as an optimisation problem and derives the efficient frontier of execution strategies trading off expected cost against variance — a framework now embedded in virtually every institutional algorithmic trading system. Chriss also wrote "Black-Scholes and Beyond: Option Pricing Models" (1997), a comprehensive textbook on option pricing theory that was widely used in graduate finance courses and by derivatives practitioners. The book covers the original Black-Scholes model in depth, as well as extensions including jump-diffusion models, stochastic volatility, and exotic options. Chriss has been an important figure at the intersection of mathematics, academic research, and practical quantitative trading. He later became interested in sports analytics and machine learning, applying quantitative methods to player performance evaluation and sports team management — an extension of his quantitative trading approach to a new domain.
