We study [Roll, R., A mean/variance analysis of tracking error. J. Portfolio Manage., 1992, 18, 13–22.] conjecture that there exists an implicit value in index-tracking (IVIT) relative to forming m...

Multi-constrained indefinite separable quadratic optimization occurs in many practical applications. However, it is an NP-hard problem and its solution even for problems of moderate size is computationally tedious. Extending our previous work on sing

We study the impact of liquidity in optimal portfolio choice under leveraging to improve risk-adjusted and absolute returns. We consider a quasi-elastic market with continuous trading where temporary liquidity costs are sufficiently large relative to
