We investigate the association between corporate international diversification and the accuracy and bias of consensus analysts' earnings forecasts. We find that greater corporate international diversification is associated with less accurate and more optimistic forecasts. Our results suggest...

Since Shalit and Yitzhalit (1984) the Mean-Extended Gini (MEG) has been proposed as a workable alternative to the classical Markowitz mean-variance CAPM. Although MEG keeps under control the risk belonging to the left-tail of the return distribution, small attention is reserved to potential...

Empirical evidence indicates that trades by institutional investors have sizable effects on asset prices, generating phenomena such as index effects, asset-class effects and others. It is difficult to explain such phenomena within standard representative-agent asset pricing models. In this...

We consider the problem of finding a strategy that tracks the volume weighted average price (VWAP) of a stock, a key measure of execution quality for large orders used by institutional investors. We obtain the optimal, dynamic, VWAP tracking strategy in closed form in a model with general price...

Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure and can be successfully used to construct robust portfolios that perform well during equity market drops. We start with a classical 60 percent Bonds/ 40 percent Stocks portfolio with monthly rebalancing that...

We discuss performance of some known market anomalies like equal-weighted index, low volatility stock index, factor anomalies of Andrea Frazzini, Ronen Israel and Tobias J. Moskowitz. We suggest the utilization of these anomalies through dynamic risk allocation in portfolios based on these...

We study a concept of dynamic leverage which is a risk measure generalizing traditional value at risk type measures. This measure is suited for hedge funds and can be applied to quantify risk in a fund of hedge funds. Dynamic leverage depends on the level of fund volatility, time horizon and...

Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure. A classical portfolio insurance strategy of Black-Jones-Perold can be easily implemented with leveraged ETFs. More complex dynamic portfolio strategies that also can be implemented using leveraged ETFs. We...

One year after Coronovirus and three years later after initially suggesting them, we revisit the performance of balanced portfolios of leveraged ETFs that we initially suggested in the 2017 paper. Leveraged ETFs provide a convenient mechanism to dynamically change portfolio exposure and can be...
