Asset Management Services

As you search for investment management services, you’re likely seeking firms with a proven investment philosophy, unique strategies that you cannot find elsewhere and a stable team that has experience in multiple market cycles. In essence, you’re looking for a firm to help you invest and manage your assets in a way that enables you to reach your investment goals.

THB Asset Management is an experienced asset management firm with a diverse selection of investment strategies. Our professionals research inefficient, neglected opportunities in the domestic and international developed markets to uncover ideas that provide returns for our clients.

THB Has Experience

Our experienced investment management team has decades of combined experience in domestic and international investment opportunities. We understand the markets, as well as how to translate the raw data into opportunities others may overlook. Our Investment ideas emerge from the inherent inefficiencies of the markets we invest in. THB Asset Management includes portfolio managers, experienced research analysts, traders and administrative personnel who work to bring you niche investment solutions that can serve your long- term investment goals.

THB Asset Management is a pioneer in the field. We started our Small Cap Special Situations strategy in 1982 and launched one of the first US Microcap Strategies in 1998. Then, in 2015, we launched the THB International Opportunities strategy focused on micro cap opportunities in the international developed markets. We believe it is one of the few strategies of its kind offered today and will quickly become part of a growing asset class as witnessed in the US market.
