我國指數股票型基金上市後之績效分析

王韻晴 Unknown Date (has links)
從投資組合理論與效率市場假說來看,影響投資績效之主要因素為資產配置而非選股或擇時能力,相關之實証亦發現主動式投資策略並無法獲得持續優於大盤的報酬,因此被動式投資策略將是一較佳的選擇。自先鋒集團在1976年率先推出指數基金之後,此類指數化投資商品即呈現指數化成長。而我國亦在2003年6月30日正式推出第一檔指數股票型基金「臺灣50指數股票型基金,簡稱TTT」。 本論文以投資人的角度來分析TTT之報酬率及成交量,從追蹤誤差及溢折價來觀察基金之報酬率,研究造成追蹤誤差之主要影響因子為何與實物創造或贖回機制是否能有效發揮功用,使TTT之市價可貼進基金淨值,以免如同封閉型基金大都折價交易,而影響投資人之獲利率。此外,更進一步比較TTT與其他指數化商品之差異性以供投資人選擇投資標的時參考。 本研究發現影響追蹤誤差之因素主要為指數成份股之增刪、公眾流通係數之調整與現金股利的發放。雖然在短期下上述因素會影響基金報酬,但長期而言基金報酬與指數相當,甚或更為略高,故在衡量長期績效時臺灣50指數可做為一良好的報酬指標。而從溢折價來分析時,由於市場交易機制,使得TTT自上市以來之流動性不足,市場效率性不高,溢折價幅度較大。此點與成交量之分析結果一致,研究發現TTT之成交量並未因出現套利機會而顯著增加,投資人買賣TTT主要在於避險或投機需求。 雖然現階段我國尚未出現指數基金,但若未來有出現類似之商品時,在目前我國停徵證券交易所得稅的環境下,投資金額的大小將非決定選擇指數基金或TTT之關鍵因素,投資期間與「質」的因素才是主要關鍵。當投資期間愈長,TTT之高交易成本的影響程度將降低,其可在盤中隨時買賣及低追蹤誤差等「質」方面的優勢將提高,TTT將相對較具吸引力。而臺灣50指數期貨由於交易成本及流動性風險較高,因而投資人較不偏好操作臺灣50指數期貨。

臺灣50指數期貨與基金上市後臺灣期貨與現貨市場之分析 / The Analysis of Taiwan Futures and Spot Markets after Taiwan 50 Futures and Taiwan Top50 Tracker Fund Trading

洪文琪, Hung, WenChi Unknown Date (has links)
本文係針對臺灣50指數期貨與基金於2003年6月30日上市之後,臺灣期貨及現貨市場報酬率間領先落後關係與波動性的變化來進行探討。研究分為兩部份,第一部份是觀察臺灣50指數期貨與現貨之間的關聯性,並探討臺灣加權股價指數、金融保險類股股價指數及電子類股股價指數期貨與現貨市場間的變化;第二部份是採用可模擬現貨走勢的臺灣50指數基金、國泰金及臺積電的股價來做為現貨的替代變數,觀察其與期貨之間的關連性是否與第一部份的結果類似,若是實證結果極為相同,則相關機構與一般投資人將可運用各期貨與其標的指數中市值最大的股票來進行套利操作。此外,本文在進行模型估計時,首度採用一階段估計法,來聯合估計雙變量GARCH模型中的條件平均數方程式與條件變異數方程式,以避免過去相關文獻將兩條方程式個別估計時所造成的估計誤差。 實證結果所獲得的重要結論如下:首先,臺灣期貨市場的發展仍未趨成熟,並不具有價格發現的功能,在考慮風險溢酬方面,僅有臺灣50指數期貨與現貨的投資人會在報酬率之外,額外要求用以補償的風險溢酬,再者,臺灣50指數期貨與基金的上市,並沒有對臺灣現有的期貨與現貨市場造成顯著的影響,然而,替代變數並不能完全取代現貨指數,但相較之下,國泰金在臺灣50指數期貨與基金上市之後的那段期間模擬成效最好。 / This paper investigates the change of lead-lag relationship in returns and volatilities in Taiwan futures and spot markets after the introduction of Taiwan 50 Futures and Taiwan Top50 Tracker Fund (TTT) on June 30, 2003. The study divides into two parts. The first part examines the relationship between Taiwan 50 Futures and spot markets, and also discusses the change of Taiwan Stock Exchange Capitalization Weighted Stock Index, Taiwan Stock Exchange Banking and Insurance Sector Index, and Taiwan Stock Exchange Electronic Sector Index in futures and spot markets. Another part uses the stock price of TTT, Cathay Financial Holding Company and Taiwan Semiconductor Manufacturing Company as the substitutive variables of spot index and goes a step further to examine the relationships between them and futures individually. Additionally, this research used One-Pass Method for first time to estimate jointly the conditional mean equation and conditional variance equation of Bivariate GARCH Model to avoid estimating error in previous relative studies with Two-Pass Method. The major empirical results are as follows: first, the development of Taiwan futures market is incomplete. The futures market does not play the price discovery role to the spot market. Second, under the consideration of risk premium, only investors in Taiwan 50 Futures and spot markets would ask for compensated risk premium excepting returns. Third, the opening of Taiwan 50 Futures and TTT does not influence significantly Taiwan futures and spot markets. Last but not least, these substitutive variables can not replace spot index perfectly. However, comparing with others, the stock price of Cathay Financial Holding Company is the very model of Taiwan Stock Exchange Banking and Insurance Sector Index after the introduction of Taiwan 50 Futures and TTT.
