U.S. Large Cap Growth

The hallmark of our Firm’s investment approach is our adherence to a disciplined process in all market conditions. Our U.S. Large Cap Growth Investment Team has maintained the same philosophy and portfolio construction process for the past 18+ years. Over this time, our process has been tested in virtually every market environment.

Our approach is balanced, in that we strive for consistent outperformance within the context of careful attention to risk management. Portfolios are constructed from the bottom-up based on proprietary fundamental research done by our Sector Portfolio Managers/Analysts, each of whom have extensive analytical experience and sector specialization. By conducting their own research, our investment professionals stay close to the many sources of information that are used in their decision-making process.
