Their method is based on the managed portfolio construction technique and makes it more tractable for fund managers. The key points of this work are as follows: (i) the authors impose constraints on active weights against to the pre-specified benchmark weights, and (ii) the authors show empirically that the constraints stabilize and improve the portfolio performance by backtests.TOPICS: Portfolio management/multi-asset allocation, performance measurement
