Stability, Asymmetry and Seasonality of Fund Performance: An Analysis of Australian Multi‐sector Managed Funds

Using a sample of Australian Multi-sector trusts we examine selectivity and market timing performance and extend the analysis to include the relatively new measure of volatility timing. This is of particular relevance to our data set, as high levels of volatility persistence are prevalent in Australia. In addition we consider the stability, asymmetry and seasonality of the various performance and risk measures. A survivorship adjustment procedure is also employed in order to assess the impact of survivorship on selectivity, market timing and volatility timing performance.

Are the Best Small Companies the Best Investments?

Previous research finds that large companies previously judged to be excellent growth companies have subsequently been poor investments. We examine small companies selected by Business Week on the basis of multiple criteria used in annual articles featuring highly rated growth companies. We study the investment performance over the three years before eleven annual Business Week publications and the three years after publication. We find positive excess returns in the pre‐publication period, but negative excess returns in the post‐publication period. This reversal in investment performance appears to be due to a mean‐reversion tendency in operating performance, in which the earnings and the past rates of return on capital of such companies subsequently decrease significantly.     

中国工业制成品出口增长的影响因素研究:基于1994～2005年分行业面板数据的经验分析

本文使用1994~2005年分行业经济统计数据和详细的贸易数据考察工业制成品出口增长的影响因素。本文基于国民经济行业两位数分类、HS两位数分类、SITC三位数分类三种分类标准,构建了微观产业层次的面板数据。经验检验表明,技术升级是出口增长的重要原因,技术复杂度越高的行业,出口增长速度越快;出口增长中存在显著的本土市场效应,相对于古典国际贸易理论,新贸易理论能对中国出口增长提供更为合理的解释。此外,本文还检验了出口企业所有制结构、贸易方式、行业发展前景、行业盈利能力、国际贸易形势等因素对行业出口增长的影响。
