With over 25 years in financial markets, William Alexandre Abbou is the founder of Arisope Capital Management, a proprietary investment firm specializing in systematic macro investing and portfolio allocation across equities, FX, rates, and commodities.
As a disciplined top-down asset allocator, he focuses on risk management, diversification, and liquid, scalable strategies. His approach leverages proprietary systematic signals, filtered and structured within a robust portfolio construction framework designed to generate uncorrelated returns and deliver alpha across market cycles.
Before launching Arisope, William gained extensive experience across both the sell-side and buy-side. At Morgan Stanley and Société Générale, he worked on the equity derivatives flow desk, developing a deep understanding of derivatives markets, institutional flows, and structured solutions. Transitioning to the buy-side, he was a Portfolio Manager at H2O Asset Management, where he applied a macro-driven framework across a diversified range of equity strategies, including systematic, style-based, macro, relative value, and event-driven approaches.
William holds a Global Executive MBA from TRIUM (NYU Stern, LSE, HEC Paris) and a Master’s in Macroeconomics & Banking and Finance from Université Paris Panthéon Assas.
