I'm a discretionary macro investor and multi-asset trader based in Dubai. I currently manage institutional capital across multiple investment mandates, applying a research-driven framework that integrates macroeconomic analysis, fundamental research, technical positioning, and disciplined risk management.
My expertise spans equities, derivatives, commodities, and global macro markets, with a focus on identifying high-conviction opportunities arising from shifts in economic conditions, policy regimes, market structure, and investor behaviour.
Before joining a Family Office as a Multi-Asset Trader, I worked in Global Dealing at Skybound Wealth, where I developed a new execution framework that reduced operational errors by 92% across more than 6,000 client portfolios. I also contributed to investment committee discussions covering asset allocation, portfolio construction, and market strategy.
Lumley Trading was created to give investors direct insight into the research, decision-making, and portfolio management process behind my investment approach.
