Thomson Horstmann & Bryant

THB is passionate about managing stable, diversified, niche equity strategies for our corporate, endowment and high net worth investors.

Our Commitment

At THB, we partner with our clients – investors including corporations, endowments, foundations, and family offices – to invest in stable, diversified equity products. We have a rich history managing allocations on behalf of large plan sponsors, while our range of pooled investment vehicles also makes THB ideal for smaller plans and high net worth investors seeking well-diversified and efficient exposure to the markets in which we invest.

Our sole focus is to provide excellent stewardship of our clients’ capital over full market cycles, and we are passionate about our disciplined process of investing in micro, small, and mid cap companies.


Founded in 1982, THB has been investing and trading in niche equity markets for over 35 years. Our accomplished team of investment professionals constantly strives to find the best investment ideas to produce outstanding results.


We are a boutique firm specializing in US Micro, Small, Mid Cap and International Microcap strategies. We maintain a disciplined, market-tested investment philosophy and an active investment approach to create broad diversification and efficient exposure in the respective asset classes.


THB is an employee-owned investment management boutique with over 35 years’ experience, a time-tested investment process, and alignment with our clients through our equity ownership and investments in the strategies we manage. We pride ourselves on our entrepreneurial culture and commitment to innovation and improvement.

In June 2018, we celebrated the 20th anniversary of our US Micro Cap strategy and are proud of the returns we have delivered to clients through the various markets, economic cycles and macro events. We believe our returns are reflective of what the combination of a sound philosophy, consistent investment approach, and an inefficient asset class can deliver to clients.

As we did in 1998 with the launch of one of the industry’s first US Micro Cap portfolios, we recently launched the THB International Opportunities strategy – a microcap strategy focused on the international developed markets. We anticipate a similar opportunity for alpha generation versus more efficient larger cap international stocks. The combination of the two microcap strategies allows our clients to create one of the first global micro cap portfolios focused solely on the developed markets.

We have a robust, systematic process that encompasses all facets of risk including ESG factors. We are a signatory of the Principles for Responsible Investment Initiative (UNPRI) and the Montreal Carbon Pledge.

We would greatly enjoy the opportunity to share our process and philosophy with you.
