What Thg Securities Advisors, Llc does

THG Securities Advisors, LLC ("THGSA") is a Pasadena, California-based investment management firm that operates as the general partner and investment manager of THG Securities Fund, L.P., an investment partnership focused on public securities including common stocks, bonds, convertible securities, preferred shares, and derivatives. The firm's core methodology is fundamental financial analysis combined with proprietary due diligence that leverages networks of C-level executives and seasoned investors. Investment activity concentrates on underfollowed public companies in North America, Canada, and Western Europe, executed through a long-biased strategy of 12-15 approximately equally-weighted positions, with active engagement ranging from board-level (potential board seats) to passive or tactical holding.

THGSA generates revenue through recurring management fees on the fund's assets under management, charged to outside limited partners. Its go-to-market is relationship-driven rather than scaled marketing: capital is sourced through the professional networks of its two co-founders — Mark K. Holdsworth (formerly Co-Founder and Managing Partner of Tennenbaum Capital Partners, ~$9B AUM acquired by BlackRock in 2018) and Zachary D. Levenick (formerly Principal at Taconic Capital Partners for 18 years) — and through the wider Holdsworth Group ecosystem, which also advises other family offices and companies on investment strategy. The customer base spans institutional investors, family offices, and qualified investors participating in the fund.

The firm has no disclosed headcount beyond its two principals, no public revenue figures, no disclosed AUM, and no recorded funding rounds. Investment decisions require unanimous partner approval, which the firm describes as enforcing rigor and high conviction; risk management emphasizes avoidance of permanent capital loss with simple liquid hedges used opportunistically. Operationally, THGSA is a focused two-principal boutique integrated into a broader multi-asset family-office platform rather than a scaled asset manager.
