Summa Corp.

Summa Corp. provides investment advice, supervisory services, portfolio consulting and family office services to individuals (including high‑net‑worth clients), corporations and other business entities. The firm delivers both discretionary and non‑discretionary portfolio management and consulting, typically charging advisory fees assessed as a percentage of assets under management.

The firm’s stated investment approach emphasizes long‑term capital preservation and seeking positive absolute returns through customized portfolios built with fundamental analysis and diversification across equities, fixed income, ETFs, structured notes and selected hedge funds. Summa relies on external research providers and adjusts allocations to market conditions, noting that hedge fund allocations are limited to strategies with significant track records and carry liquidity and transparency constraints.

Summa is distinctive for its scale relative to team size, managing roughly $459 million across about 63 client accounts with two advisors, and for its role serving other investment adviser clients via sub‑advisory arrangements. The firm also maintains international relationships — including reciprocal sub‑advisory work with a foreign‑registered adviser and a Foreign Solicitor arrangement — which correspond with a meaningful non‑U.S. client presence that is uncommon among similarly supported firms.
