摘要: 本文旨在探讨台湾投信公司所发行的开放型共同基金中,投资者应该如何针对不同的基金属性、经济环境、投资期间采取不同的投资策略。为了使研究样本期间包含完整景气循环周期,本研究所采用的样本期间为2000年1月至2007年12月,共156档开放型共同基金。相对于过去文献,本研究具有下列特点:第一、为了增加研究的可参考性,本研究采用基金的历史真实净值取代利用蒙地卡罗模拟法模拟基金净值。第二、专注研究台湾投信公司发行之开放性共同基金。第三、台湾投资者在基金投资上以长期投资居多,过去实证研究多数强调基金的短期投资绩效,研究期间以一年居多,考虑台湾投资者的投资习性,本研究尝试将基金投资期间拉长,分为长、短期两种。第四、过去文献在基金绩效衡量上以报酬率为主要衡量指标,然而本研究在绩效衡量上以期末终值为衡量指标,期末终值考虑了投资期间与投资报酬率,故可以真实反映投资者的报酬。第五、本文以风险值衡量投资风险,风险值在计算上考虑基金报酬率的标准差、基金投资期间与原始投入金额,故相较于标准差,风险值较能衡量投资者须承担的风险。
实证结果发现,在相同风险值的前提下,以定期定额方式投资基金之期末终值大于单笔投资;在相同的期末终值下,单笔投资需承担的风险值高于定期定额,由此可知定期定额的绩效优于单笔投资。另外,在拉长投资期间与经济处于繁荣时期的情况下,单笔投资绩效优于定期定额的机率将提升。
This text aims to analyze how to choose investment strategy within different kinds of Taiwan mutual funds. In order to make the samples of study include an eco-nomic cycle, 156 Taiwan mutual funds from 2000 to 2007 are adopted.
Compare past studies, this research has the following characteristics: First, this research adopts the true historical net value of mutual funds to replace simulating net value. Second, focus on Taiwan mutual funds. Third, Taiwan investors toward to hold mutual funds in long-term investment, but past studies almost concentrated in short-term investment, accordingly, the research includes long-term and short-term investment. Fourth, the research adopts terminal value and variance as performance indicators.
Evidence shows under the same terminal value, the variance of lump-sum in-vestment is larger than dollar-average cost investment; on the other hand, under the same variance, the terminal value of dollar-average cost investment is larger than lump-sum investment. In addition, the probability that the investment performance of lump-sum investment is superior to the dollar-average cost investment will be im-proved when the economy is prosperous and long-term investment.
