The research question
A forecast of tomorrow’s return can be viewed as a probability distribution rather than a single value. My thesis investigated how ideas from data-driven optimal transport could inform that distribution, and how dynamic programming could connect a forecast to a sequence of decisions.
The mathematical approach
The work draws on the distributional barycenter problem and data-driven flows. It considers conditional density estimation, transport maps, and numerical methods for relating observed samples to an unknown distribution.
The thesis builds on work by Esteban G. Tabak, Giulio Trigila, and Wenjun Zhao. It describes a formulation that replaces a more difficult minimax optimization with a single minimization, and investigates how the approach might be applied to financial time series.
Financial setting and scope
The thesis discusses Apple, Tesla, Google, and Amazon price data collected through Tiingo, with numerical exploration in a Jupyter Notebook. Dynamic programming is considered as a way to use a conditional distribution of future returns in a financial decision problem.
This was preliminary academic work. The thesis develops an approach and its possible application; it does not establish a validated trading strategy or a claim of investment outperformance.
