About Us

Our Investment Philosophy

Mast Investments applies a process-driven investment approach focused on continuous improvement, reflecting our belief that in a rapidly changing world, the motivation to learn and adapt is more important than ever.

Central to our culture is a rigorous, research-based investment philosophy that seeks to both understand and challenge the economic underpinnings of investment strategies, and to separate durable profit opportunities from historical happenstance.

Our History

We are a leading provider of alternative investment benchmarks and systematic and process-driven investment solutions. Our team launched the HedgeIndex Main Index1 in 1999, pioneering rules-based, multi-factor investing with the LAB Liquid Index program2.
