Sequential Conditioning on Volatility Regime, Price Persistence and Distributional Asymmetry - A Framework for Adaptive S&P500 Equity Exposure
Adaptive regime-aware momentum using implied volatility information, higher-order moment dynamics and statistical price dispersion filters
My doctoral research investigates regime-aware risk management architectures within systematic equity momentum strategies. The project explores how implied volatility information, higher-order moment volatility and statistical price dispersion can be integrated with trend-following frameworks to identify structural market regime shifts and improve portfolio resilience.
The central objective of the research is to develop adaptive multi-layered filtering mechanisms capable of distinguishing between persistent momentum environments and conditions associated with market exhaustion, volatility transitions and momentum crashes. Particular emphasis is placed on the interaction between volatility structures, trend persistence and distributional asymmetries in financial markets.
My broader research interests include:
I am a doctoral researcher in Quantitative Finance at the University of York, where my research focuses on regime-aware momentum strategies, volatility regime detection and adaptive risk management frameworks for liquid equity markets.
My work investigates how implied volatility structures, higher-order moment volatility and statistical price dispersion can be integrated with systematic trend-following models to identify structural market shifts, improve persistence detection and mitigate the impact of momentum crashes and large drawdowns.
My academic research is informed by more than two decades of international experience across derivatives, commodity markets and systematic trading environments. Prior to academia, I held senior trading and risk management positions across international commodity markets, specialising in derivatives structuring and risk management.
Throughout my professional career, I have structured and managed large-scale derivatives and commodity trading operations, including the development of hedging frameworks and barter programmes involving significant cross-border exposure across agricultural and financial markets.
Alongside my doctoral research, I continue to work through Bridgholds on systematic strategy development, quantitative finance research and applied risk modelling. My technical work includes the development of Python-based research tooling for backtesting, performance attribution, parameter optimisation and regime-dependent portfolio analysis.
I hold an MSc in Financial Economics and an Executive MBA in Entrepreneurship and Finance.
