- 요약In recent years, artificial intelligence (AI) and machine learning (ML) have become essential tools in financial markets, with applications spanning from high-frequency trading to risk management. This thesis explores the theoretical foundations and practical implications of ML-driven methods in financial decision-making, focusing on reinforcement learning, statistical factor models, and diffusion models with latent factors.In Chapter 2, we establish a rigorous theoretical framework for reinforcement learning (RL) in high-frequency market making, bridging modern RL theory with continuous-time financial models. We analyze the effect of sampling frequency and uncover a tradeoff between learning error and sample complexity. Extending to a multi-agent setting, we study a two-player general-sum game and show that Nash equilibria of the discrete-time RL framework converge to their continuous-time counterparts as ∆ → 0. Our findings provide guidance for practitioners selecting sampling frequencies in high-frequency financial decision-making. In Chapter 3, we develop an estimation and inference theory for principal component analysis (PCA) under a weak factor model with cross-sectionally dependent idiosyncratic components, with the nearly minimal factor strength relative to the noise level or signal-to-noise ratio. Our theoretical innovations enable novel statistical tests for testing latent factor space, detecting structural breaks, and estimating systematic risks, with empirical validation revealing strong correlations between our test results and macroeconomic cycles.In Chapter 4, we establish the asymptotic behavior of marginal-information and full-information maximum likelihood estimators for discretely-sampled continuous-time diffusion models with latent factors. Our results demonstrate that the cost of latency, which we define as the amount of information lost when a variable is latent instead of observed, depends on whether the latent factors affect the drift or diffusion terms. To obtain these results, we employ filtering techniques and develop a new theory of nonlinear continuous-time pseudo-filters based on stochastic partial differential equations (SPDE). Monte Carlo simulations provide empirical support for our theoretical findings on the cost of latency.
