本文利用縱橫資料( Panel Data )分析法找出影響台灣股票型基金的因素。驗證基金績效與基金淨流量比率、市場報酬、風險(含總風險和系統風險)與規模呈現正向相關;基金績效與週轉率和費用率呈現負向關係。
在一元群組效果之下,僅總風險違反假說,即基金績效與總風險呈現微弱的負向關係。在群組效果之下,基金淨值報酬率的R2較高,而夏普指數、崔納指數和強森指數的R2都較低(介於0.09與0.10之間),顯示以此三項指數為應變數的一元群組模型,其預測能力較弱,且群組效果之虛擬變數皆不顯著,表示群組對基金績效沒有顯著性影響,意即基金之間無顯著性差異。
採用一元時間效果作為實證模型,經實證後發現四種基金績效指標的R2皆大幅提升(介於0.48與0.86之間)且時間之虛擬變數大多具有顯著重要性,表示時間對於基金績效的影響力較大。
故由實證的結果可知,建議投資人定期定額的購買基金時,可挑選基金淨流量比率為正、管理費用低且基金規模較大的基金在長期投資計畫下可獲得較佳的報酬。
The purpose of this study is to evaluate the performance of Taiwan stock mutual funds by Panel Data model and to identify important factors for the model. Our goal is to test the hypothesis that the performance of mutual funds has a positive relationship with the explanatory variables including the net cash flow rate, market return, risk (total risk and beta) and fund size, and to test that the performance of mutual funds has negative relationship with turnover and expense rates. It was found, under the one-way group effect model, that the performance of mutual funds indeed has met the hypothesis stated above except for the total risk.
Further, under the one-way group effect, the return of net assets value has larger coefficient determination (R2) of 0.7. While the Sharpe Ratio, Treynor Ratio and Jensen Ratio have smaller R2 values (between 0.09 and 0.10), which mean that they have a weaker interpretation by the model. In addition, the dummy variables for the group effect are not significantly important and hence, there is no significant difference among funds as far as their performance is concerned.
Under the one-way time effect model, the performance of funds has a much larger R2 value (between 0.48 and 0.86) with the explanatory variables and the dummy variables for time effect are significantly important. Therefore, time span has a significant impact on the performance of the mutual funds.
With the empirical findings, it is suggested that mutual funds be purchased by dollar cost averaging scheme over a long run, it will provide a good return to investors when they purchase funds with positive net cash flow, low management fees and large-scale.
