This internship proposal aims to address the significant challenge of managing concentrated positions in financial portfolios, which can lead to increased impact costs for banks and hedge funds due to market liquidity constraints. The project is structured into two interconnected parts: (i) estimating the Average Value-at-Risk (AVA) for concentrated positions and (ii) calculating Future Hedging costs associated with a hypothetical portfolio (gedankenportfolio). The research goals focus on developing frameworks that utilize recent academic advancements to optimize the composition of the gedankenportfolio, thereby minimizing these additional costs. The intern will gain practical experience in investment banking, learning about various financial products, risk metrics, regulatory requirements, and relevant statistical and mathematical models. This internship offers a unique opportunity to contribute to a critical area of financial research while acquiring valuable skills in a dynamic environment.
