A new MILP formulation for rebalancing enhanced index-tracking portfolios [PDF]
, 2017 The enhanced index-tracking problem consists of revising, i.e., rebalancing, a portfolio such that it achieves a given excess return over a financial index and minimizes the tracking error, i.e., the deviation of the portfolio returns from the index ...
