Tanaka Capital Management

What Tanaka Capital Management does

Tanaka Capital Management is a private, boutique investment management firm founded in 1986 by Graham Tanaka and headquartered in Greenwich, Connecticut (with a New York contact line). The firm serves high-net-worth individuals, pension plans, endowments, and retail investors through two distribution channels: a public no-load mutual fund, the TANAKA Growth Fund (ticker: TGFRX) launched in 1998, and a suite of separately managed accounts that includes All Cap Growth Equity, dedicated Small/Mid/Large Cap portfolios, the balanced Museum Portfolio combining growth equities with fixed income, and a concentrated Focus Portfolio of up to 12 names.

The firm's investment process is built around a proprietary "Platform Growth" thesis that targets undervalued growth companies with proprietary platforms capable of proliferating multiple products and services, and companies undergoing change expected to drive better-than-expected earnings over 2-5 years. Research combines top-down macroeconomic analysis in demographics, inflation, productivity, and monetary/fiscal policy with bottom-up stock selection grounded in a "kick the tires" approach that involves meeting hundreds of management teams annually and personally shopping the firm's target products. The team is intentionally small (1-10 employees), led by Graham Tanaka (President, CIO, Chief Economist; CFA, Stanford MBA, 45+ years experience), Benjamin Bratt (VP, CFO, CCO; CFA), and Donna Conti (Head of Trading and Operations; 25+ years in financial services).

The business model is asset-based fee revenue: subscription/recurring management fees on TGFRX and customized SMA fees for HNW and institutional clients. The mutual fund is distributed directly via phone (1-877-4TANAKA) and through 8+ major brokerage platforms including Fidelity, Charles Schwab, Vanguard, Wells Fargo, UBS, E*Trade/Morgan Stanley, Pershing, and Janney Montgomery Scott. Separately managed accounts are sold direct-relationship via 212-490-3380. The firm has not raised external funding, has no parent company, and operates as an independent Connecticut-domiciled entity.
