Summary
🤩
Rockstar🎓
Top SchoolEthan Tsai is a portfolio manager and quantitative researcher with 12 years of finance and STEM experience, blending applied mathematics (Simon Fraser) and an MS in Business Analytics and Risk Management (Johns Hopkins) to build proprietary backtesting and multi-factor strategies. Based in Shanghai, he has led commodity and equity quant efforts that delivered double-digit risk-adjusted returns and a fund outperforming the S&P 500 by over 50% YTD in 2024, drawing on a philosophy that fuses Graham-style financial metrics with modern machine learning and systematic hedging. Hands-on in Python ecosystems (backtrader, pyfolio, numba, pybind) and financial terminals (Bloomberg, FactSet, Wind), he converts alternative datasets—spot and inventory flows—into tradable alpha. A meticulous, results-oriented practitioner, he transitioned from international academic training and insurance sales into quant finance, demonstrating an unusual blend of client-facing commercial instincts and deep technical research. He is now seeking team-oriented hedge fund roles where his mix of practical implementation and theoretical rigor can scale systematic strategies.
