The most relevant practical impediment to an application of the Markowitz portfolio selectionapproach is the problem of estimating return moments, in particular return expectations. We analyzethe consequences of using return estimates implied by analysts’ dividend forecasts under the...

This article aims to extend evaluation of the classic multifactor model of Carhart (1997) for the case of global equity indices and to expand analysis performed in Sakowski et. al. (2015). Our intention is to test several modifications of these models to take into account different dynamics of...

We develop a four-factor model intended to capture size, value, and credit rating transition patterns in excess returns for a panel of predominantly mid- and large-cap entities. Using credit transition matrices and rating histories from 48 US issuers, we provide evidence to support a...

During the global financial crisis, stressed market conditions led to skyrocketing corporate bond spreads that could not be explained by conventional modeling approaches. This paper builds on this observation and sheds light on time-variations in the relationship between systematic risk factors...

We show analytically under quite general conditions that implied rates of return based on analysts' earnings forecasts are only a downward biased estimator for future expected one-period returns and therefore not suited for computing market risk premia. The extent of this bias is substantial as...

The most relevant practical impediment to an application of the Markowitz portfolio selection approach is the problem of estimating return moments, in particular return expectations. We analyze the consequences of using return estimates implied by analysts' dividend forecasts under the explicit...

I derive two valid forecasting models of the equity premium in monthly frequency, based on little more than no-arbitrage: A "predictability timing" version of partial least squares, given that predictability is theoretically time-varying; and a least squares model with realized market premiums...

We construct a global implied volatility surface by combining information from the index options of twenty countries and regions. The convexity of the global surface positively predicts equity premia around the world, in- and out-of-sample, at horizons from one to twelve months. Semi-annually,...

In this paper, we propose a cross-sectional option momentum strategy that is based on the risk component of delta-hedged option returns. We find strong evidence of risk continuation in option returns. Specifically, options with a high risk component significantly outperform those with a low risk...

This paper investigates the cross-sectional predictive ability of text-based factors in the cryptocurrency market --an important asset class for retail and institutional investors. We employ Bidirectional Encoder Representations from Transformers (BERT) topic modeling to analyze news articles...
