About
First Sigma Capital LLC provides discretionary portfolio management for individual and high‑net‑worth clients through separately managed accounts and reports managing roughly $9.9 million on a discretionary basis. The firm does not provide financial planning, estate, insurance, tax, or accounting services and does not participate in wrap fee programs.
The firm’s investment process combines technical, fundamental, and cyclical analysis and implements a common investment strategy while adapting portfolios for tax, suitability, and timing differences across accounts. It discloses the use of higher‑risk techniques — including short sales, leverage (margin and borrowed shares), frequent trading, and options — and describes the material risks associated with those strategies.
Notable distinctions for the firm include that it is engaged in business as an exempt Commodity Trading Advisor and that it may enter into performance‑based fee arrangements with qualified clients. The adviser requires use of a single broker‑dealer/custodian (Interactive Brokers) for all client accounts, employs block trading, and does not accept authority to vote client securities.

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
