ReSolve Riffs with ReSolve’s own Dr Andrew Butler on Integrating Prediction with Optimization
Our guest this week was Dr. Andrew Butler, Chief Investment Officer here at ReSolve. He has an Honors B.Sc. in Applied Mathematics & Physics from Memorial University, an M.A. in Applied Mathematics & Statistics, Financial Engineering from York University, and a PhD from the University of Toronto, Department of Mechanical & Industrial Engineering. Our conversation covered: Mentors, studying optimization, machine learning and emulating similaritiesComparing methodologies used in calculating oil reserves, with empirical financeMathematics, known truths, soft axioms and assumptionsData science, tools and hypothesis tests in financeComparing the definitions of “noise” and different scientific methodsRegression types, relationships and featuresExisting models vs creating models with dataHyperparameters, universes, good decision-making and edgesThe fallacy of “The Efficient Frontier” in Modern Portfolio TheoryMethods that make for good choices, and setting expectationsNeural Networks, financial data extraction and optimization scienceBuilding complex models, integrating and optimizing predictions, and making decisionsCounterintuitive predictions and “explainability” – integrated vs optimized modelsOptimizing for decision accuracy by minimizing prediction errorUsing Decision Trees, Ensembles and BoostingMarket data and making predictions using de-coupled vs integrated approachesTraining models and optimizing, going forwardOptimal covariance shrinkage and minimizing errorConstrained vs unconstrained mean variance portfolios, de-coupled vs integrated, in a managed futures contextThe effect of constraints in limiting models from being “different”The practical takeaways about integrated solutions for Advisors and Portfolio ManagersThe value of humility in optimizing for financial markets – knowledge, wisdom and experienceStochastic dominance vs t-testsTime horizons – size mattersThe Consultant Industry – monthly data vs understanding processAnd much more This is “ReSolve’s Riffs” – live on YouTube every Friday afternoon to debate the most relevant investment topics of the day, hosted by Adam Butler, Mike Philbrick and Rodrigo Gordillo of ReSolve Global* and Richard Laterman of ReSolve Asset Management Inc. *ReSolve Global Inc. refers to ReSolve Asset Management SEZC (Cayman) which is registered with the Commodity Futures Trading Commission as a commodity trading advisor and commodity pool operator.
