Head of Research and chief architect of ARK research models · ARK Invest

Built ARK's open research platform, models and datasets used to size positions and justify allocations across ARK funds

Led development and operationalization of ARK's thematic research platform, producing quantitative and qualitative models that translated disruption-themed hypotheses into position sizing and investment theses. The research infrastructure included open datasets, adoption-curve projections and scenario modelling that fed directly into trading decisions and risk limits for ARK strategies. Published and maintained analyst workstreams and whitepapers that were referenced in fund prospectuses and investor communications, thereby providing an explicit methodological basis for concentrated allocations to names such as Tesla, CRISPR-related equities and digital-asset exposures. Model outputs informed when to scale into positions and when to take profits, affecting execution schedules and block trade strategies. By institutionalizing these tools and making significant parts of the research public, established a feedback loop between ARK's published convictions and market behaviour: research drove allocations, allocations produced market impact, and market moves were then incorporated into subsequent modelling and trade plans. These concrete deliverables tied Winton's work to how the 'Ark' instrument allocated capital and managed liquidity risk.
