Investment Process

IDENTIFY OPPORTUNITIES: We identify capital growth opportunities based on proprietary research and economic analysis. Our proprietary economic research provides a global risk rating every month built upon 5 regional and 30 country-specific analyses around the globe. Our goal is to capture inflection points in the economic and business cycles and identify countries and regions with above-average trend line growth. Risk ratings govern our asset allocation.

ADAPT PORTFOLIO: Our unconstrained portfolio construction changes based on proprietary evaluation of macroeconomic environment and risks. We use various portfolio optimization techniques that vary by global risk rating to avoid tail risks in the portfolio, especially in a declining economic environment. To achieve proper diversification, portfolio allocations shift in our attempt to achieve the most efficient risk-adjusted return for investors.

We avoid unrealistic model assumptions and forward-looking economic predictions.

PROACTIVE RISK MANAGEMENT: We take a dynamic approach to risk management. Our primary goal is to align risk allocation and have specific volatility targets for different market environments.  We estimate daily volatility for various markets using proprietary techniques and consider adjustment when necessary. Our event- based risk management includes probabilistic scenario analysis and tail-risk forecasting. We attempt to manage current risk in our clients’ portfolios as well as prepare for the future.
