About
Ex Cathedra is an investment manager that implements quantitative, automated trading strategies for qualified and accredited investors and pooled capital accounts. Its strategies operate across liquid instruments—including U.S. and international equities, debt securities, futures, options, foreign exchange, and related derivatives—and are managed on a discretionary basis.
The firm relies on proprietary mathematical and statistical models developed with academic counterparties and staff holding advanced degrees; strategies are split into fixed‑income and speculative components, with the speculative sleeve designed to be market‑neutral (target beta around 0.3). Clients must explicitly consent to the use of leverage, and the firm discloses that speculative strategies may use long‑term average leverage near 3:1; the brochure also notes the firm uses derivatives within separately managed accounts, an approach that is uncommon among peers.
Notable operational features include registration as a Commodity Trading Adviser and membership in the NFA, an owner‑operated governance structure with internal mitigations for self‑supervision, and unusually detailed monthly reporting that lists all trades and mark‑to‑market outcomes. The firm reported no regulatory assets under management as of July 18, 2024, and reserves the right to tailor investment guidelines to individual investor requirements.

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
