Greybox Investments provides fee-only portfolio management primarily to individual and high-net-worth clients, as well as charitable organizations, other registered investment advisers and corporations, managing roughly $177 million across about 104 client relationships. Services emphasize discretionary wealth management delivered through separately managed accounts, unified managed accounts and custom portfolio solutions rather than a packaged financial planning offering.

The firm’s investment approach is quantitative and multi-factor, building style- and sector-based component equity strategies typically composed of 30–60 holdings and incorporating ADRs, ETFs and GDRs where appropriate. Portfolios are constructed using forward-looking risk and return forecasts, internal and external investment components, tax-efficient rebalancing and optional social equity screening, and the firm also offers custom SMA models to other RIAs on negotiated terms.

What is distinctive about Greybox relative to many peer teams is its explicit absence of standalone financial planning services and its focus on scalable, model-driven portfolio construction and distribution to other advisers. The firm also emphasizes institutional custody relationships, block trading and bespoke account constraints that can produce account-level differences from model performance, a set of operational features less commonly emphasized among similar-sized team firms.
