The Resampled Method To Improve The Efficient Frontier In Minimizing Estimation Error: The Case Of Malaysia Equity Portfolios

Since the work of Markowitz (1952), Mean-Variance (MV) analysis has been a central focus of financial economics. MV theory is still used as a foundation of the modern finance for asset management. Problems involving quadratic objective functions or loss functions generally incorporate a MV analys...
