We consider the use of mean-variance analysis in investment decisions. Mean-variance analysis provides a simple tool to rank investments by comparing the expected returns and return variances of those investments. The rule itself is simple and elegant, when we compare two risky investments, if...

This paper introduces a new trading strategy in investment: to include the asset (Asset A) with the highest mean, the asset (Asset B) that stochastically dominates many other assets, and the asset (Asset C) with the smallest standard deviation in their portfolio to form the portfolio in the...

We test for arbitrage opportunities and market efficiency in the Hong Kong money, stock, and real estate markets. We find that the money market, represented by the Exchange Fund Bills, stochastically dominates both the stock and real estate markets, represented by the Hang Seng Index and the...

Since the 1980s, the global economy has shown a general trend of transition from an industrial economy to a service economy. The service industry has gradually become an important engine for world economic growth. The intelligent service industry has developed rapidly and has become an important...

In this paper, we first develop some properties to state the relationships among central moments, stochastic dominance (SD), risk-seeking stochastic dominance (RSD), and integrals for the general utility functions and the polynomial utility functions of both risk averters and risk seekers. We...

Barberis, Shleifer and Vishny (1998) and others have developed Bayesian models to explain investors' behavioral biases by using the conservatism heuristics and the representativeness heuristics in making decisions. To extend their work, Lam, Liu, and Wong (2010) have developed a model of weight...

This paper examines the long- run equilibrium relationships between the major stock indices of Singapore and the United States and selected macroeconomic variables by means of time series data for the period January 1982 to December 2002. The results of various cointegration tests suggest that...

The American dollar has been the anchor currency of the international monetary system and no other currencies have so far been able to rival the greenback in its standing. Does the birth of Euro pose a challenge to the hegemony of the dollar as the predominant currency? This paper seeks to...

A number of problems in economics, finance, information theory, insurance, and generally in decision making under uncertainty rely on estimates of the covariance between (transformed) random variables, which can for example be losses, risks, incomes, financial returns, etc. Several avenues...

This study adopts the Markov-switching ARCH (hereafter SWARCH) model to examine the volatility nature and volatility linkages of four segmented Chinese stock indices (SHA, SZA, SHB, and SZB). Our empirical findings are consistent with the following notions. First, we find strong evidence of...
