The results show that a fund achieves considerably higher net returns with TCA optimization than with traditional quadratic programming methods that do not directly consider transactions costs. For a large-cap, 50-stock portfolio, the improvement in net returns was on average +4.5 bp to +8.2 bp and as high as +7.6 bp to +13.5 bp. For a large-cap, 100-stock portfolio, the improvement in net returns was on average +3.2bp to +7.0 bp and as high as +5.0 bp to +10.2 bp. These results show that a manager can start with a seemingly suboptimal or inefficient ex ante portfolio in traditional mean variance space and earn higher ex post net returns after accounting for transaction costs.TOPICS: Portfolio construction, statistical methods}, issn = {1559-3967}, URL = {https://jot.pm-research.com/content/11/2/11}, eprint = {https://jot.pm-research.com/content/11/2/11.full.pdf}, journal = {The Journal of Trading (Retired)} }
