Registered Investment Advisor · Miami Beach · Est. 2019
Discretionary capital management across a flexible, mandate-free structure. Alpha is sourced across instruments, asset classes, and market regimes — driven by a multi-factor signal process that is generalist by design. Capital follows the opportunity. There is no mandate requiring it to do otherwise.
About RCG
Robin Capital Group is a Miami Beach-based Registered Investment Advisor founded in 2019. We manage approximately $35 million in discretionary capital across a flexible, mandate-free structure — each strategy designed around a specific risk profile and operated with the institutional discipline the firm's principals developed across two decades at Citadel Securities, Citadel, and Bank of America.
Every client holds their assets in their own name, with full position-level transparency at all times. There are no commingled funds, no gates, no lock-ups. Capital is allocated wherever a multi-factor signal process identifies the most attractive risk-adjusted opportunity — across instruments, asset classes, and market regimes.
Three strategies have been running since May 2022 across multiple market regimes. The performance record is live, audited, and available below.
"Every investment edge decays. Markets change regime, capital crowds the trade, and yesterday's signal becomes tomorrow's noise. The only durable advantage is a process built to recognize that — and adapt before the drawdown forces it."
RCG Investment Philosophy
US Treasuries & investment-grade bonds. Capital preservation with active duration management — designed to anchor the defensive allocation through rate cycles and credit stress.
Cross-asset rotation across global equity, fixed income & commodity ETFs driven by systematic macro signals. No mandate to stay invested when conditions are unfavorable.
High-conviction positions in US companies at the early stages of a fundamental earnings turn. Built for investors seeking aggressive growth with institutional-grade discipline.

Research & Insights
RCG publishes ongoing research on portfolio construction, systematic alpha generation, and the discipline of managing capital across market regimes. Written by Nick Diaz, CIO — the intellectual framework behind every allocation decision, explained without a sales agenda.

Risk Management
At RCG, risk management is not applied after the investment decision — it is the foundation the decision is built on. Treating the denominator of your Sharpe ratio as the primary design variable, not an afterthought, is the discipline we carried from institutional fixed income desks into every portfolio construction decision.
Every client account is sized and structured around their specific risk tolerance, liquidity needs, and investment horizon. A strategy generating 25% annually with a Sharpe below 0.3 is a worse outcome than one generating 18% with a Sharpe of 0.85.
Automated risk monitoring runs continuously across all three strategies. Position sizing, drawdown limits, correlation exposure, and regime signals are tracked in real time — so human judgment is applied at the moments it genuinely adds value.
RCG operates exclusively in liquid, exchange-traded instruments. Every position can be reduced or eliminated within hours — without negotiation, without delay. This is both a risk management choice and a client service standard.
Team
Nick brings over twenty years of institutional experience in systematic and discretionary trading and portfolio management. He founded and built Robin Capital Group as a sole practitioner — designing its investment philosophy, constructing its three live strategies, and developing the systematic infrastructure that underlies the firm's operations.
Prior to founding RCG, Nick held senior roles at Citadel Securities, Citadel, and Bank of America in Chicago, New York, and London, covering rates, market making, and high-frequency trading. That career across three financial capitals — spanning institutional fixed income, derivatives, and systematic execution — shaped the cross-market perspective on risk and capital allocation that defines RCG's investment approach. RCG's track record since May 2022, across multiple market regimes and in real client capital, reflects that body of work entirely. Nick holds an M.S. in Finance and a B.S.E. from Universidad Adolfo Ibáñez (UAI) in Santiago, Chile, and currently holds his Series 65 as a registered Investment Advisor Representative.
Nick is also Co-Founder and Co-CIO of Nezumia, a separate quantitative AI hedge fund co-founded with Patrick S. Huggins — a quantitative researcher with prior roles at Citadel Securities, Citadel, and HSBC, and holder of a Ph.D. in Computer Science with a concentration in Artificial Intelligence from Yale University and a B.S. in Mathematics and Computer Science from NYU. Nezumia represents a distinct thesis — one that recent advances in AI have made possible: a fully autonomous asset manager in which AI drives every stage of the investment process, from alpha generation and signal sourcing to execution and risk management, with no discretionary overlay. The two firms are independent ventures that happen to share a founder, not extensions of one another.
Ashley brings a rare combination of front-line advisory experience and deep regulatory expertise to her role at RCG. A University of British Columbia alumna, she built her career in financial services across Chicago, holding roles at Citibank, Wayne Hummer Investments, and Wintrust.
During that period, Ashley accumulated an exceptional breadth of credentials — including her Series 7, Series 66, Illinois Life & Health, and Registered Paraplanner designation — and worked in a dedicated wealth management and retirement planning capacity alongside one of the most successful advisory practices in the Chicago metropolitan area. That experience gave her an unusually thorough grounding in both the technical and client-facing dimensions of financial services.
At RCG, Ashley holds her Series 65 as a registered Investment Advisor — the designation appropriate to the firm's RIA structure — and leads the firm's compliance and operations functions. She is responsible for maintaining the practice's regulatory standing, overseeing RIA registrations, regulatory filings, and ongoing compliance with evolving SEC and state-level requirements, while also managing day-to-day operations and client engagement. Her background ensures that every client interaction is handled with the care, precision, and professionalism that RCG applies to its investment process.
