A Note From Our Founder

We believe active portfolio management leads to superior wealth creation and better risk-adjusted results over time. Our investment approach combines top-down trend analysis with bottom-up fundamental company research and then applies a strict valuation discipline to security selection.

The core of our organization is driven by a working philosophy which stresses a team-based investment management structure, independent thinking, in-depth and in-house research, and a long-term focus.

We invest alongside our clients and mutual fund shareholders and have a pride of independent ownership.
