Investment Management

Cowen had $11 billion in assets under management as of January 1, 2018. We offer innovative alternative investment products ranging from public market hedge to private equity, royalties and real estate strategies.

Over decades, Cowen’s leadership has proven its ability to utilize balance sheet capital to build, grow and foster the investment teams that have brought vital and relevant strategies to our clients.

The founding managing members of the investment management division (Peter Cohen, Thomas Strauss, Jeff Solomon, and the late Morgan Stark) utilized decades of extensive experience derived from prior positions at the most senior levels in global capital markets and investment management to build Cowen’s investment management division.

We have an established network of relationships within the global financial community, as well as a seasoned perspective on the disciplines required to manage successful investment programs. In addition, we have assembled a professional support staff with their own extensive experience within their disciplines.

The founding managing members and senior-level professionals have collectively made significant personal investments in both the investment management division and, alongside Cowen’s clients, in most of the various portfolio strategies.
