Why are 'true' active managers essential for markets? by John Galakis Abstract: There has been tremendous growth in the assets managed through passive strategies both by institutional and private investors, especially over the last 20 years. This trend is not expected to abate anytime soon; on the contrary, it is projected to intensify, as investors have been increasingly rotating out of underperforming and higher cost active strategies into lower cost index-related ones. Besides cost, index-linked investing exhibits numerous benefits. There is, however, ample empirical evidence that shows that it is creating widespread price distortions that have considerable impact on individual security and market risk/return distributions. This dark side of passive investing has sizeable repercussions for corporate investing and investor portfolio allocation decisions. In this environment, the presence of true active managers is essential, as they could offset part of the distortions.

An Efficient Equity Investing Model Using Smart Beta Based on Market Phase Information by Rei Yamamoto Abstract: Recently, smart beta has become popular and its exchange-traded funds (ETFs) are now sold by asset management companies. Therefore, by using low-cost smart beta ETFs, we can easily conduct factor investing. We propose a market phase classification method based on market directions and cross-sectional volatility to explain the rates of return of smart beta indices and a conditional portfolio optimization model to use the characteristics of these rates of return. Empirical analyses show that our proposed model achieves better performance than both the market index and a normal portfolio optimization model used in Japanese and global markets. Keywords: asset management; smart beta; factor investing; portfolio optimization; conditional mean-absolute deviation model; market phase information.
