Guidelines |
The objective of this thesis is to investigate the connection between the 1/N portfolio strategy and the notion of the uninformative prior within Bayesian statistics. This investigation posits each asset as a probabilistic model, each with its unique state price density. When investors allocate their portfolio equally across assets, known as the 1/N portfolio, it symbolically mirrors the selection of an uninformative prior in Bayesian terms. This thesis will delve into the nuances of this connection, specifically how the equally weighted portfolio strategy aligns with the concept of prior distribution and its subsequent influence on the posterior distribution in Bayesian statistics.
Furthermore, the study will juxtapose the 1/N portfolio against a portfolio that mimics the asset yielding the highest return, resembling a frequentist approach to model selection. This comparison aims to examine the hypothesis that both Bayesian and frequentist portfolio strategies converge asymptotically. To empirically validate these theoretical insights, the thesis will employ simulations using real-world data sets, such as a collection of major currencies (e.g., G10) or a set of significant assets (e.g., Dow Jones Industrial Average). Through these simulations, the thesis seeks to provide a comprehensive understanding of how Bayesian and frequentist perspectives manifest in portfolio management, particularly in the context of asset allocation and model selection. |
