We introduce a new class of momentum strategies, the risk-adjusted time series momentum (RAMOM) strategies, which are … how these volatility measures can be used for risk management. We find that momentum risk management significantly … increases Sharpe ratios, but at the same time may lead to more pronounced negative skewness and tail risk. Furthermore, momentum …

risk distribution of financial assets. In conventional financial theory, investors are considered to be rational and any … changes in relevant risk are assumed to be a result of the movement in fundamental factors. However, herein this study, it is … hypothesized that there are movements in risk that are driven by volatility linked to sentiment-driven noise trader activity whose …

Should long-term investors account for time-variation in model parameters? We develop a time-varying Vector Autoregressive model that can handle time-variation in intercepts, slopes, volatility and correlation, the leverage effect in volatility and fat tails. Long-term investors should take...

We propose a novel approach for analysis of the composition of an equity mutual fund based on the time series decomposition of the price movements of the individual stocks of the fund. The proposed scheme can be applied to check whether the style proclaimed for a mutual fund actually matches...

The paper examines the performance of four multivariate volatility models, namely CCC, VARMA-GARCH, DCC and BEKK, for the crude oil spot and futures returns of two major benchmark international crude oil markets, Brent and WTI, to calculate optimal portfolio weights and optimal hedge ratios, and...

We develop a finite-sample procedure to test for mean-variance efficiency and spanning without imposing any parametric assumptions on the distribution of model disturbances. In so doing, we provide an exact distribution-free method to test uniform linear restrictions in multivariate linear...
