Investment Philosophy
-
Macro Driven
Analysis of the Macro environment is at the core of the investment process. Assimilating the widest range of external inputs, we form our own views. We believe a changing investment environment requires adaptation, innovation and relentless focus.
-
Factor Analysis
Investment Factors rather than asset classes are our toolkit for analysing the macro environment, for managing investments and for assessing risk. Factor analysis enables the selection of the optimum investment structure through the seamless integration of conventional and alternative investment strategies and the adoption of appropriate portfolio hedging.
-
Deal Selection
Selecting the right opportunities is central to the investment process. With access to a broad network of partners and transactions, we focus on investments that demonstrate clear potential for high growth while aligning with our strategic outlook and investor objectives. Our approach combines rigorous evaluation with disciplined judgment to identify opportunities where access, timing, and conviction intersect.
