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.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.

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. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
