Streszczenie:

This dissertation investigates the long-term performance of momentum portfolios. Its results show striking asymmetries for winners and losers and imply potentially different causes for the winner and loser components of momentum. After separately examining winners and losers relative to their respective benchmark portfolios with no momentum, we find winner momentum is smaller in magnitude, persists only for six months, and its higher return fully reverses. This is consistent with the notion that winner momentum is an overreaction to positive news and potentially destabilizing. Loser momentum i

The research presented in this thesis addresses different aspects of dynamic portfolio construction and portfolio risk measurement. It brings the research on dynamic portfolio optimization, replicating portfolio construction, dynamic portfolio risk measurement and volatility forecast together. The overall aim of this research is threefold. First, it is aimed to examine the portfolio construction and risk measurement performance of a broad set of volatility forecast and portfolio optimization model. Second, in an effort to improve their forecast accuracy and portfolio construction performance,

This paper develops a Bayesian Global VAR (GVAR) model to track the international transmission dynamics of two stylized shocks, namely a supply and demand shock to US-based safe assets. Our main findings can be summarized as follows. First, we find that (positive) supply-sided shocks lead to pronounced increases in economic activity which spills over to foreign countries. The impact of supply-sided shocks can also be seen for other quantities of interest, most notably equity prices and exchange rates in Europe. Second, a demand-sided shock leads to an appreciation of the US dollar and generall

This paper analyses the difference in risk-adjusted returns between Sin-stocks and SRI-investing for the period 2001-2021. The analysis was conducted by creating two optimally risky portfolios according to the Modern Portfolio Theory, one comprised of only Sin-stocks and one with only high ESG scoring companies. The Sin-stocks contained stocks from four different sectors, alcohol, gambling, tobacco and weapons while the companies for the SRI-portfolio was chosen from the FTSE4Good index. The regression models were chosen to follow both the CAPM, and the Fama & French three factor model and

However, that portfolio selection model used variance as the measure of investment risk. In fact, asymmetrical return distributions will render the variance a deficient measure of investment risk, since it punishes the desirable upside movements as hard as the undesirable downside movements. Therefore, this study proposed a new portfolio s

In the Modern Portfolio Theory, people can eliminate the unsystematic risk by diversifying their investments and just taking the systematic risk in the portfolio. The academia also thinks that asset allocation is the main fact which affecting the return the performance of mutual fund. The algorithm in analyzing long term asset allocation is the mean─variance, however, it disobey the investors’ real feeling that use the standard deviation as the risk measurement.

But based on this method, an increase and a decrease in prices of financial asset are treated the same. However, the risk that investor really want to avoid is that the price of assets decrease. Due to the above reason, Bawa and Lindenberg (1977) and Fishburn (1977) develop a theory to evaluate the downside risk named “Mean Lower-Partial-Moment” (MLPM) which is derived from the concept of the Lower Partial Moment.

The traditional portfolio ranking methods are based on the mean-variance (M-V) model. Although this two-moment method is convenient, it may be insufficient to characterize return distributions. Therefore, mean-lower partial moment (M-LPM) model is employed to examine the impact of the two factors on portfolio selection for the period 1986-2000 in Taiwan. Our results show that the size and book-to-market effects do exist in Ta
