Portfolio management starts with asset allocation. There is a consensus that asset allocation plays an important role in determining portfolio performance (Arshanapalli, Coggin & Nelson, 2001). Active portfolio management implies the rebalancing of the existing portfolio by buying and selling assets. The aim of rebalancing is to improve the performance of the managed portfolio by adjusting it t...

In this paper, we compare the portfolio allocation model of multifractal detrended Fluctuation approach with the modern efficient frontier model and the asset allocation model from Chinese institution fund, the risk-return performance of the multifractal detrended Fluctuation turns out to be more optimal portfolio allocation than that from Chinese institution fund and the conclusions have impli...

I examine an investor’s portfolio allocation problem across multiple risky assets in the presence of return predictability when, in addition to the predictability evidence, the investor uses conditional asset pricing models to guide him in the portfolio selection decision. I also explore how the uncertainty associated with the model dynamics affects the investor’s optimal portfolio. To analyze ...

We advance the theory pertaining to IT governance and portfolio management. We specifically examine how the portfolio characteristics can influence IT investment allocation. We propose two portfolio characteristics – flexibility and diversity. We define the flexibility as the number of IT investment choice, and the diversity as the dissimilarity of IT investment choice. Using the Monte Carlo si...

Optimal asset allocation strategies of defined-contribution pension plans for members whose terminal utility is a power function of wealth-to-wage ratio is investigated in this paper. The portfolio problem is to maximize the expected terminal utility in the presence of three risk sources, interest risk, asset risk and wage risk. A closed form solution is found for the asset allocation problem a...

This paper examines some performance measures to be considered as an alternative of the Sharpe Ratio. More specifically, we analyze allocation problems taking into consideration portfolio selection models based on different performance ratios. For each allocation problem, we compare the maximum expected utility observing all the portfolio selection approaches proposed here. We also discuss an e...
