Forecasting in a
Connected World

Commodities have undergone an information revolution. From ship tracking to oil storage levels and crop yields, more data on supply, demand, storage and transport is available than ever before. Commodity markets are more globally connected: natural gas markets impact fertilizer production, agricultural markets impact gasoline production.

Understanding these dynamics with the goal of delivering consistent investment returns presents a set of incredible opportunities and complex challenges. We bring together exceptional people to do just that. We combine specialist domain expertise with advanced modeling techniques to solve problems that others deem unsolvable.

A Specialized,
Integrated Approach

We emphasize depth over breadth of understanding, modeling markets at the deepest level of granularity. Using a large and growing array of diverse data sources, we run these models in a fast and flexible manner against thousands of assumptions and scenarios to explore our investment hypotheses.

Our investment technology underpins every aspect of our process. Our engineers drive the ingestion of data, the distributed computation of our scenarios and our trade execution algorithms. Many are embedded within our investment teams and focus on specific product types. Others provide robust environments and tooling for our global strategy.

The team’s culture emphasizes collaboration, rigor and debate. Some of our hardest problems span multiple commodities and geographies. We collaborate across investment teams to solve them together. In turn, we make better-informed decisions.

This model drives our growth, and today are one of the largest alternative investment managers in the commodities markets.
