This paper examines whether sell-side security analysts follow momentum or create momentum by themselves for recommending stocks. We employ an indirect method of testing the role of analysts by assigning projected recommendation scores for the neglected stocks to mitigate the so-called...

In the paper we introduce an empirical approximation of the log-optimal investment strategy that guarantees an almost optimal growth rate of investments. The proposed strategy also considers the effects of portfolio rearrangement costs on growth optimality and advises a suboptimal portfolio for...

This paper aims to analyze so-called anomalies or additional risk factors (other than market risk) on the Hong Kong stock exchange. To do so, we first select arbitrarily several factors that we a priori believe to be significant, we then collect the data and evaluate the returns associated with...

The conduct of US monetary policy is often accompanied by controversial debates on the adequacy of monetary conditions. These can result from different concepts of excess liquidity measures. The paper analyzes the theoretical and empirical information content of these concepts for asset markets....

This paper aims to study the role of gold quoted at Paris (physic and paper) in the diversification of French portfolios on the period from 2004 to 2009 including the financial crisis period 2007-2009. The results show that the correlation of gold with stocks and with bonds is very weak. At the...

The influence of the CAPM theory on the financial theory of investment has increased with the development of passive management. Today, equity or fixed-income market portfolios can easily be defined using equity and fixed-income indexes. These indexes also play an important role in active...

This paper analyzes whether the market portfolio is efficiently related to benchmark portfolios formed on size, value, momentum and reversal with various utility theories by using stochastic dominance criteria. The results support the prospect theory including assumption of loss aversion at...

We will in this paper discuss Quadratic Programming (QP) and portfolio optimization. Long-short portfolio has traditionally been hard to optimize because of the non-binding equality constraint i.e. the long posit ions are cancel out by the short positions. We have shown in this paper that such a...

The previous literature on momentum investments has only considered the so called unconstrained momentum return. This paper will investigate budget constrained momentum returns by using two different datasets. The conclusion is that unconstrained momentum returns systematically overestimate the...

Many different studies such as Kelly (1956) have an analyzed the characteristics of log-return investment models. We will in this paper discuss such models both from a theoretical and empirical perspective. We show by estimating the kernel density function for empirical data that the optimal bet...
