The Firm

Firm Overview

CenterBook Partners is an innovative multi-manager alpha capture platform that integrates the best of fundamental, systematic, and multi-manager investing.

The Problem

Fundamental investors are the best stock pickers and can rapidly adapt to changing market dynamics. However, they struggle to capture the excess return potential of their research due to behavioral biases, cognitive errors, and lesser expertise in risk management.

Quantitative investors are experts in portfolio construction and risk management, but tend to lack sources of persistent, high-quality alpha and often adapt more slowly to non-linear changes in the market.

Multi-managers provide consistency of performance, but restrictions imposed on their contributors’ investment strategies limit the alpha they can generate.

The CenterBook Solution

CenterBook believes that integrating the uniquely human skill of evaluating equities with the superior computational power and consistency of machines represents the next frontier for the investment management industry.

CenterBook’s Centaur investment strategies are named after the chess “Centaur” strategy that combines human chess champions with computers running chess software to outperform each individually.

CenterBook magnifies the potential of this “human + machine” approach by bringing together independent fundamental managers in its “open-architecture” platform.

Our strategies deliver a value proposition to investors that they cannot access elsewhere: direct exposure to the best ideas of multiple independent fundamental managers in a systematically constructed “center book” portfolio.
