We propose a model of portfolio selection that adjusts an investors' portfolio allocation in accordance with changing market liquidity environments and market conditions. We found that market liquidity provides a useful “leading indicator” in dynamic asset allocation. Specifically, market...

Research showing that the lowest risk stocks tend to outperform the highest risk stocks over time has led to rapid growth in so-called low-risk equity investing in recent years. We examine the performance of the low-risk strategy previously considered in the literature and of a beta-neutral...

Assets invested in passively managed equity mutual funds and exchange traded funds (ETFs) have grown steadily in recent years, reaching more than one trillion dollars at the end of 2010.
