Thesis

             My interest is to explain why asset prices move as they do, and how to optimally use this information for portfolio selection purposes, especially when there is a large number of assets.

             First, I discuss broad market movements and how long-horizon investors form expectations about prices. I focus on a particular setting in which heterogeneous agents choose trading strategies looking at their past performance, adopting the agnostic view of changing them if the market tells them wrong.

             Later, I focus on the more practical issues of portfolio selection within a context of a large number of assets. In particular, I study how grouping the assets according to a given (exogenous) rule improves the performance of the resulting portfolios within a constrained estimation framework.

             In my third paper, I use the same constrained estimation framework to obtain better forecasts of investment-grade credit-spreads. Within this framework it is possible to use (much) smaller estimation windows that better capture changing regimes in this market.
