Brian Ong Email and Phone Number
My key interest lies in building a modular simulation framework and pricing engine to deliver a forward-looking simulation-based approach to portfolio construction. This allows us to disentangle from modern portfolio theory, and move toward a portfolio construction process that can be assessed via many metrics (such as portfolio accrued cash flow, ex-ante drawdown) for a portfolio with instrument exposures that are changing dynamically in time.My other interests include technical analysis and algorithmic trading with Python.
