Sparse spanning portfolios and under-diversification with second-order stochastic dominance

Battle Count: 35

Highly relevant for portfolio construction and risk management in quantitative trading strategies, especially for those focusing on sparse asset selection and risk-adjusted performance.

Requires implementation of Linear Programming and greedy algorithms, as well as understanding of stochastic dominance concepts. Moderate to high complexity for practical implementation.

The paper provides detailed methodology and empirical procedures, enhancing reproducibility. However, specific dataset details may be needed for full reproduction.
