Little attention has been paid in the literature to the impact of different investment horizons on the portfolio compositiondespite its importance to portfolio managers. One exception isthe study by Gunthorpe and Levy (1994) on the U.S. stock market.Our paper extends the same study to the stock markets of Japan,Hong Kong and Korea. Using 40 individual stocks in each market,our results support those of Gunthorpe and Levy (1994) in thatthe composition of an optimal portfolio depends heavily on theinvestment horizon. When the investment horizon lengthens, theproportion of defensive stocks becomes larger while that ofaggressive stocks becomes smaller. 相似文献

Ethical Unit Trust Financial Performance: Small Company Effects and Fund Size Effects 总被引:1,自引:0,他引:1
Alan Gregory John Matatko & Robert Luther 《Journal of Business Finance & Accounting》1997,24(5):705-725
Recent papers which have examined unit trusts have controlled either for a 'fund size effect' or for the 'small firms effect' in the investment portfolio. The contribution of this paper is an analysis of the 'small firms effect' whilst simultaneously controlling for the 'fund size effect'. We show that the ethical unit trusts have significantly greater exposure than general unit trusts to the 'small firms effect', and that net of this there is no significant evidence of over or under performance by ethical trusts using an adjusted Jensen measure. Using two cross-sectional approaches, we demonstrate that whilst a 'small firms effect' has a role to play in explaining unit trust performance, fund size is not correlated with the financial performance of unit trusts. This cross-sectional analysis also provides some evidence that ethical unit trusts may perform less well than general unit trusts. 相似文献

This paper studies the benefits of diversifying into real estate and other assets that typify the wealth held by Japanese
investors. We examine movements in mean variance frontiers by employing spanning tests to assess the statistical significance
of frontier shifts. We also investigate the impact of shifts in mean variance frontiers before and after the precipitous decline
in Japanese real estate and stock market values that began in 1990. Spanning tests show that real estate, short and long-term
bonds, and Japanese equity provide significant diversification benefits. We find that mean variance frontiers shift after
1990. Statistically significant shifts are also economically important as measured by Sharpe ratio changes. Although significant,
the portfolio weights on Japanese real estate are relatively small compared to their composition found in surveys of Japanese
household wealth. 相似文献

This study investigates whether foreign investment enterprises (FIEs) in China alter their corporate reporting behavior in response to a known schedule of tax-rate increases. The context of this investigation is a tax-incentive scheme that allows firms to pay taxes at a reduced rate for a limited period of time, and then at a higher rate when this period expires. If managers attempt to maximize firm value by minimizing tax costs, then the spread of tax rates in the periods surrounding the rate change may provide a substantial incentive for them to accelerate revenue and defer expenses. Consistent with this hypothesis, the empirical results indicate that firms report significantly higher discretionary current accruals for the years before tax-rate increases. The evidence, which indicates that firms manage earnings upward to take advantage of lower tax rates that are available in certain years, has important implications for tax policymakers. 相似文献
