About
Grinnell Capital provides discretionary asset management, financial planning, and subadvisory/outsourced CIO services to individuals (including high‑net‑worth clients), trusts, estates and charitable organizations. The firm operates with a single advisory professional and a small client roster, delivering ongoing portfolio management tailored to client goals and periodic financial planning engagements.
Investment programs are organized into multiple model suites — Traditional, Impact (sustainability‑focused), Momentum equity, and a Momentum ETF model — and the firm uses fundamental, technical and quantitative analysis to construct and monitor portfolios. Holdings may include stocks, bonds, mutual funds and ETFs as well as inverse and volatility ETFs, options and other derivatives; the Momentum strategies are run with position limits and defined basket sizes (typically 25–50 securities for Momentum and 8–15 ETFs for the Momentum ETF model).
Compared with many peers, the firm’s combination of subadvisory/outsourced CIO services and an explicit Impact product alongside tactical Momentum strategies that employ derivatives is atypical for a small adviser with modest assets under management. Operational distinctions include requiring custody at specified custodians (Charles Schwab or Interactive Brokers), treating cash as an asset class within its models, and not accepting proxy‑voting authority from clients.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
