Stack Financial Management

Zach Jonson, CFA, serves as Vice President and Chief Investment Officer, leading an investment committee that includes Founder and CEO James Stack, Senior Portfolio Managers Annell Danczyk, CFA and Joe Laszewski, CFA/CPA, and other senior professionals. The committee makes discretionary asset allocation and security selection decisions guided by the firm's 'safety-first' risk-management framework.

Stack does not pursue private deal flow or alternative investments. The firm operates exclusively in public equity markets, sourcing investment opportunities through internal equity market research and security analysis. The portfolio management team's recommendations go directly to the investment committee, which sets the firm's concentrated equity strategies.

Stack runs direct public-equity portfolios managed in-house. There is no indication in firm disclosures of fund-of-fund, private-fund commitments, or allocation to external alternative managers. The practice is built entirely around discretionary, concentrated equity mandates.

James Stack founded the RIA in 1994; his spouse Lisa Stack serves as a Managing Partner. No other Stack-branded operating company, foundation, or investment vehicle appears in public materials, and the firm discloses no affiliate relationships beyond its single registered entity in Whitefish, Montana.

Downside risk management is the firm's defining investment principle. Stack describes its approach as 'safety-first,' built on historical market-risk assessment, with the objective of strong capital protection in declining markets and competitive participation in rising ones. Every portfolio is stress-tested against historical forces that have driven equity market drawdowns.
