About
Rockingstone Advisors is an SEC-registered investment adviser that manages approximately $280 million for roughly 61 clients, primarily high-net-worth and individual investors, as well as trusts, retirement plans and select OCIO engagements. The firm provides discretionary portfolio management across multiple asset classes—equities, fixed income, hybrids, alternatives, real estate and digital assets—and historically offered corporate advisory services before discontinuing that offering in late 2023.
The firm follows a multi-step, actively managed investment process that begins with strategic asset allocation, incorporates tactical adjustments and sub-asset diversification, and proceeds to security and digital‑asset selection, execution and ongoing monitoring. Rockingstone routinely employs active techniques including short sales, options and other derivatives, and it may use borrowing (margin) in separately managed accounts; it also operates a digital-asset program requiring client accounts with a digital‑asset custodian.
What is noteworthy relative to many supported peers is that Rockingstone advertises performance results and explicitly discloses the use of borrowing and derivatives in separately managed accounts—practices that are relatively uncommon in the peer group. The firm also serves as an OCIO for select clients and in 2025 reclassified about $22 million from assets under advisement to discretionary assets under management, reflecting that institutional oversight role.

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
