In this study we estimate the survival time of momentum in six UK style portfolios' returns in the period October 1980–June 2014. We utilise the Kaplan-Meier estimator, a non-parametric method that measures the probability that momentum will persist beyond the present month. This probability...

Fama-French/Carhart alphas of passive indices should be zero, but the recent empirical evidence shows otherwise. We propose an optimisation algorithm that makes minor adjustments to the time series for the market, size, value and momentum factors, which ensures zero alpha for a self-designated...

In this paper we investigate the risk-adjusted performance of US sector portfolios and sector rotation strategy using the alphas from the Fama-French five factor model. We find that five factor model fits better the returns of US sector portfolios than the three factor model, but that...

This paper assesses the relationship between risk-shifting of mutual funds, measured as benchmark-adjusted factor-based investment style change following a structural break, and their risk-adjusted performance. We isolate only the breaks in style risk beyond those embedded in the funds’...
