The Team

Mark Mowrey, CFA

Chief Investment Officer

With a career in investment research and management spanning nearly two decades, Signature Resources’ Chief Investment Officer, Mark Mowrey, brings a uniquely broad and relevant expertise to the firm. Graduated from the Wharton School of the University of Pennsylvania and holding the Chartered Financial Analyst® designation, his roles have ranged from financial journalism and sell-side equity research to the management of multi-billion-dollar investment portfolios.

Having endured several capital market cycles during his industry tenure, Mark has learned firsthand the power of a quantitative methodology, grounded in an approach that fosters continual learning, to impart a beneficial discipline to the investment process. He further believes candid, transparent reviews of investment methods and results nurtures the trust that is required for clients and colleagues to share in the team’s confidence in its work.

Even so, Mark understands that confidence is at best a secondary source of investment success and that hubris and similar emotional states only detract from the investment process. Rather, he believes a methodical approach, grounded in more than a century’s-worth of collective industry knowledge development and evolved to be relevant to the investment challenges and opportunities of today, will enable the firm to assist clients in targeting their investment goals.
