Sionna Investment Managers

What Sionna Investment Managers does

Sionna Investment Managers Inc. is a privately held, employee-owned Canadian investment management firm founded in 2002 by Kim Shannon and headquartered in Toronto. The firm provides discretionary investment management services using a value investing approach that combines quantitative screening (including its proprietary Intrinsic Value Model, or IVM) with qualitative fundamental analysis to identify quality businesses trading below intrinsic value. Sionna serves three core client segments: institutional investors (foundations, endowments, and pensions), private high-net-worth clients via separately managed accounts and pooled funds, and retail investors accessing Sionna's strategies through the Bridgehouse Asset Managers mutual fund and separately managed account platforms across Canada.

Sionna's product surface spans multiple equity strategies including Canadian Large Cap, All Cap, Focused Canadian Value, Fundamental Value, Focused Canadian Dividend, High Conviction, Global, International, U.S., Resource Environmental Evolution, and Canadian Balanced, the last delivered in partnership with sub-advisor Lorica Investment Counsel for fixed income. The firm generates revenue primarily through recurring asset-based advisory and administration fees (percentage of client assets under management) on its Sionna Pooled Funds and separately managed accounts, with additional economics from Brandes-Sionna mutual funds distributed through Bridgehouse. Sionna is registered as Portfolio Manager across 12+ Canadian provinces and territories, as Exempt Market Dealer in Ontario and Newfoundland and Labrador, and as Investment Fund Manager in Ontario and Quebec.

The firm is the largest Canadian investment management firm founded by a woman, with founder Kim Shannon (Co-CIO, lead PM on multiple strategies) inducted into the IIAC Investment Industry Hall of Fame in 2022 and co-authoring 'The Value Proposition' documenting the firm's investment philosophy. The investment team includes Co-CIO Stephen Jenkins (joined 2019), who leads U.S., International, Global, and High Conviction strategies, alongside several other CFA-chartered portfolio managers. No funding rounds, M&A activity, or external ownership are disclosed, and the firm operates an active independent practice with no public ticker or parent entity.
