Morningstar is an independent provider of investment research and provide information on approximately 380 000 investment offerings about mutual funds. Morningstar are most known for their “star” rating system, which rates funds from the lowest 1-star to the highest 5-stars. Since investors frequently use fund data provided by Morningstar, we will evaluate whether investing in funds with higher fees and higher ratings would end up with higher returns. Examinations will be made if there is a relationship between mutual fund performance and the management fees within top-rated (5-star) funds and bottom-rated (1-&2-star). The mutual funds which are included in this thesis are United Kingdom (UK) managed and invested in three different markets; Asia-Pacific except-Japan, Europe except UK-Large Cap, and the United States (US) Market. This allows us to compare different markets at different stages of maturity. The results clearly show that the top-rated funds within all three markets outperformed the bottom-rated funds. Furthermore, the results demonstrate that the investor in general will earn a higher return by paying a higher management fee (TER) for the top-rated funds in all regions. The results also show that the TER for the bottom-rated funds in Europe and US market is higher compared to the top-rated funds. This means that the investor will pay higher fees for funds that do not perform well.

<p>This dissertation studies the impact of mutual fund managers' beliefs on fund performance in the first chapter and focuses on the impact of firm behavior on stock performance in the second chapter. </p> <p><br></p> <p>In the first chapter, I utilize the Revealed Preference Theory to recover fund manager belief formation directly from their actual trading activities. By relating stock holdings in a fund's portfolio to past factor returns, I document three facts about managers' belief formation: 1. In contrast to belief extrapolation, a substantial fraction of mutual fund managers act as contrarian investors who expect lower factor returns after a good factor performance; 2. Whether a fund trades in an extrapolative or contrarian way is due to its managers' expectation biases rather than fund style investment strategy, fund catering strategy or fund risk preference; and 3. Contrarian managers generate superior performance, are more experienced investors, charge higher expense ratios, and manage smaller US equity funds. The top (contrarian) managers significantly outperform the bottom (extrapolative) managers by a return of 3.4% per annum after adjusting by FFC4 factor models.</p> <p><br></p> <p>The second chapter is co-authored paper with Yan Liu and Feng Zhang. In this chapter, we systematically replicate the bulk of long-run event studies conducted in the last three decades from 1990 to 2020 using extended samples and four long-run performance measures. The final sample contains 62 papers of long-run event studies and 148 corporate events. Our findings suggest that long-run return anomalies documented in the last three decades are not robust, and firms do not earn long-run abnormal returns following various types of corporate events. Only 2% of the 148 corporate events we replicate earn post-event abnormal returns that are statistically significant at the 5% level based on all the four performance measures, and the fraction further shrinks to 0% at the 1% significance level. Viewed together, our findings suggest that these long-run abnormal returns after corporate events are likely the result of data mining or "p-hacking".</p>

The following dissertation contains two unique empirical studies that contribute to the overall literature in the field of Financial Economics in the areas of mutual fund investing and financial intermediation and regulation. The first Chapter, entitled “The Impact of Macroeconomic Stress on the U.S. Financial Sector”, examines the relative impact of macroeconomic stress on financial and non-financial U.S. firms. Empirical results show that macroeconomic shocks appear to have a larger impact on financial firms. Additionally, the sensitivity of financial firms to macroeconomic events can be traced to the influence of non-depository institutions, or “shadow banks”, like finance and investment companies, which are less regulated than depository institutions. The results coincide with several trends in the financial sector including increased competition, complexity and interconnectedness and highlight the need for governance mechanisms that account for the risks associated with these factors. The second chapter, entitled “Partial Adjustment Towards Equilibrium Mutual Fund Allocations: Evidence from U.S.-based Equity Mutual Funds”, examines the relative efficiency of equity mutual funds in terms of speed of portfolio adjustment by applying a partial adjustment model. Empirical results show that mutual fund managers are able and willing to quickly adjust their portfolios when results have been sub-optimal, implying that the cost of persistent poor performance is perceived as being high. Managers can offset about 106 percent of the deviation within one period. Additionally, results show that funds that typically engage in the costly production of specialized information, like emerging market and sector funds have more efficient speeds of portfolio adjustment than more passive funds, like market index funds. The results imply that actively managed funds may have efficiency advantages that have been previously ignored in the empirical literature.

共同基金是未來投資理財約主流!專業法人機構在股市之投資比重日益提高，對國內證券市場生態產生結構性改變。展望未來趨勢，隨著股市發展成熟化、上市上櫃公司遽增與金融市場情勢連動關係複雜化等因素，專業投資理財時代的來臨必將成為事實。「專業、分工理財」投資型態將逐漸取代以往投資人自行下海操作之「自助式理財」型態。故共同基金操作績效正是進行本評鑑研究的最大動機，其中辨認基金經理人操作策略與績效顯現最具代表性的指標--選股能力與擇時能力．乃本研究所欲深入探討的主題。本研究模型之構建乃根據 Lee-Rahman (1990) 所提出之改良評鑑模式，簡言之，該模型的發展歷經早期 Treynor & Mazuy (1966) 的理論雛形，並經過 Jensen 針對評鑑擇時能力方面之改進，然後再經由 Bhattacharya & Pfleiderer (1983) 的進一步修正，產生了較完善的整體架構，最後經由 Lee-Rahman (1990) 針對評鑑過程中評鑑迴歸式之殘餘項異質性問題，作一根本的解決，建構完整的基金選股與市場擇時能力績效之評鑑模式。同時並運用幾個傳統績效評鑑指標 (即 Treynor、 Sharpe 與 Jensen 指標三種)，作為基金整體性績效之輔助研究。 實證結果顯示:(一)在基金整體績效評估方面，得到的結果顯示不論研究期間的長短．基金表現擊敗大盤的比例皆高於五成，約介於 60% 至 70% 左右，而在 Treynor、Sharpe 與 Jensen 指標三種不同評鑑模式分析下，基金績效排名有相當顯著的一致性。(二)在選股與市場擇時能力評鑑( Lee-Rahman 修正模型)方面:1.同時兼具選股與市場擇時能力的基金皆有穩定的一致性;2.大多頭時期基金擇時能力普遍提昇、新投信基金績效表現較優異。(三)整合比較結論方面:1.本研究中不同的評鑑模式所得實證結果十分肯定基金績效的持續性與穩定性;2.基金顯著的擇時能力並非基金整體績效脫穎而出的決定性因素，績效傑出與否幾乎決定於選股功力因素:3.台灣股市投資 Bottom-up 的投資邏輯漸漸取代 Top-down ;4.新投信績效已有凌駕老投信的趨勢。 / Mutual Funds Investment will be very popular! While the professional institutionalist's participation being promoted, domestic stock market environment has beenchanged structurally. In the future, accompanied by several reasons such us the_maturationof stock market, dramatic increasing in listed company numbers and more complex correlation in international financial markets, the age stressing on professional financial adversary will come. "Professional financial investment and adversary" will substitute for"Self-adversary" investment. Therefore, measuring the mutual fund's performance is the mailmotivation of my study', and the insight in selectivity ability and market timing ability will bethe subject for further research. The research model is based on the Lee-Rahman's modified model (1990), that is, the model structure was first built by Treynor & Mazuy (1966), improved by Jensen in Timingability measurement, and then revised by Bhattacharya & Pfleiderer (1983), and throughout structured by solving the "heteroscedasticity" in error terms of regressions finally Therefore, the better integral research model on measuring selectivity ability a timing abilityhas been accomplished. Meanwhile, we also use three traditional performance measure(Treynor, Sharpe & Jensen index) to be the general performance research. Empirical results show that (1)By measuring the general performance of mutual funds, we know that about 60%-70% funds managers beat market at each research period, and there exists consistency of fund's performance ranking among those three measures. (2) By using Lee-Rahman modified model (1990), we got three conclusions. First, for those funds consist of selectivity and timing ability, there exists consistency. In bull market period, timing ability of most funds performed better generally, and new funds had better performance. (3) Integral comparative conclusions have four results. First, no matter what measures being used, empirical results confirm stability and consistency in performance ranking. Second, significant timing ability is not the determinate factor of significant performance, significant selectivity ability plays the determinate role. Third, in Taiwan, bottom-up investment strategy gradually substitutes for top-down investment strategy. Finally, new mutual funds investment co. had outperformed old mutual funds investment institutions.

The Master thesis "Analysis of selected investment funds in the Czech republic" deals with collective investments with focus on mutual funds. The first part is dedicated to definition of the term collective investments, its history and general characteristics of mutual funds. The middle part is dedicated at firts to the czech market of collective investment and the analysis of this market. The last part focuses on comparison of the performance of selected funds and its characteristics.

The result is the construction and analysis of the potential appreciation of the investment strategy interpreted through historical data and a comparison of the results with alternative options for the appreciation of financial capital, especially in the form of mutual funds.

近年基金投資已然成為一般民眾重要的理財工具之一，而投資人最關注的顯然是基金績效的好壞，以及前績效好的基金在未來能否持續先前好的績效表現。因此本論文主要探討台灣的開放式股票型基金之績效、基金績效的持續性，以及投資人買賣基金的行為與基金績效之間的相互影響。論文第一部份是從隨機變數的觀點評估台灣的開放式股票型基金其夏普指標績效值，第二部份則以一般化的馬可夫模型－「漂移者—停駐者」模型評估基金績效持續性的動態行為，第三部份討論投資人的現金流量和基金績效之間的關聯性。 在第一部份的實證結果中，我們認為過去對夏普指標高的基金其績效較佳之想法必須修正，因為從隨機變數的觀點衡量基金的夏普指標值時，所有基金的績效均不顯著異於0。若與市場指數的夏普指標相比，並非所有基金經理人都能打敗市場，雖然以五年評估期間衡量基金績效時，有半數以上的基金其績效顯著優於市場指數，但在二年評估期間下只有極少數基金的績效顯著優於市場。第三，以拔靴法模擬基金的小樣本夏普指標分配時，仍然無法找到基金績效顯著大於零的證據。整體而言，本部份的研究認為從隨機變數的觀點衡量基金的夏普指標績效時，台灣的開放式股票型基金其績效超越市場的證據並不強。 第二部份以「漂移者—停駐者」模型衡量基金績效的動態持續性之實證結果，我們發現整體基金市場具有某種程度的績效持續性，但績效持續性的強弱程度隨著績效組別的不同而有差異，表現最佳與最差兩組基金的績效持續性高於績效中等基金，但整體基金的績效持續性並不很明顯。另外，績效最差組別的停駐基金比率為各組中最高，代表該組別基金的績效持續性較強。第二，基金績效持續性因績效指標的不同而有差異，主要差異反映在各績效組別裡停駐基金比率的估計。第三，「存活偏誤」的確對基金績效持續性的結果有影響，但主要影響反應在停駐基金比率的估計，而非績效漂移基金的轉換機率。第四，以概度比檢定驗證單純馬可夫鏈模型與「漂移者—停駐者」模型對資料的配適程度時，發現「漂移者—停駐者」模型較適合分析台灣開放式股票型基金的績效持續性。 就第三部份基金績效與投資人現金流量的討論，第一，實證結果支持台灣的開放式股票型基金其績效具有持續性，但整體市場的績效持續性並不顯著，其中季資料下基金績效的持續性證據最強，此部份與論文第二部份的結論一致。第二，前一季績效佳的基金在下一季能吸引投資人較多的現金流量，但是放入市場報酬率作為解釋因子後，我們發現投資人的現金流入隨著市場報酬率的上升而提高、隨著基金報酬率的增加而減少，因此投資人買賣基金的主要考量似乎是以市場整體走勢為主，而非基金前期績效。第三，投資人買賣基金的活動對基金後續績效並無影響，這可能是基金經理人的持股比率高於法令規定，或是投資人買入贖回基金的活動對績效的影響通常在數日內即已反應完畢。最後，討論經理人的流動性交易及訊息交易對基金後續績效的影響之前，我們發現基金前期績效的持續大約維持兩個月，但是加入流動性交易及訊息交易作為解釋變數後，基金績效的持續性減弱。 / Mutual funds have been a popular investment vehicle in recent years regardless of the growth of fund assets or numbers of beneficiaries. What investors mind are that whether mutual funds can provide higher return than others, star managers can persist previous dominant performance. For the reasons, we try to examine the performance of Taiwan mutual funds by Sharpe ratio index from new insights, and study mutual fund within best performance group can maintain antecedently superior performance. Finally, we attempt to investigate the relationship between fund performance and fund flows of open-ended stock fund in Taiwan. 1. We analysis the statistical distribution of the Sharpe ratio in Taiwan Mutual Funds developed by Lo(2002) and explore fund performance. First, we construct the confidence intervals of Sharpe ratio of Taiwan stock funds under different assumption for the return-generating process is independently and identically distributed returns (IID) and Non-IID but stationary, then, annualize Monthly Sharpe ratios by Time Aggregation technique. To avoid small sampling errors, we utilize bootstrap sampling conception to simulate the small sample distribution of Sharpe ratio of stock funds. We find that (1) there are not significant evidences that mutual funds in Taiwan have superior performance than riskless rate or market returns in several conditions. (2)By Bootstrapping sampling technique, we still cannot find stock funds have comparatively better performance than market indexes from empirical result. Accordingly, we believe that the usual methods about Sharpe ratios must be modified. That is, a mutual fund with higher Sharpe ratio is not necessarily a good performance, absolutely. Cause, Sharpe ratio index is not a constant, but a random variable, and we must build up its interval estimation and then test if there are significant differences between funds performance. Consequently, we argue it is relatively important to construct the performance-ranking system of mutual funds similar the bond credit-rating. 2. We employ the mover-stayer model to study the dynamics of performance persistence of mutual funds in Taiwan. This model provides us more detailed information about and help us further understand the nature of mutual fund performance persistence. We find (1) that there exists certain degree of persistence in mutual fund performance. Such persistence is, however, not very significant. It is because most funds are mover funds with unstable performance rather than stayer funds with consistence performance. More interestingly, funds within the best and the worst performance groups have more persistent performance than those within the middle performance group. It implies that in view of the previous mediocre performance, fund managers within the middle group have strong intention to improve their future performance. In addition, the fact that the worst performance group has the highest proportion of stayer funds implies that losers are more persistent than winners in Taiwan mutual fund industry. Overall, mutual funds in Taiwan have only weak performance persistence. (2) that consistent with the literature, the degree of persistence in performance is dependent on the performance evaluation criteria. It seems that this difference of degree of persistence is reflected in the estimation of stayer fund proportion, not in the estimation of the transition probability matrix of mover funds. (3) that there exists survivorship bias in our study. It mainly influences the estimation of stayer funds proportion, not that of the transition probability matrix of mover funds. Having said that , we believe that this bias will not alter the important conclusions of this article. 3. This part studies three important issues including the performance persistence of mutual funds, the relationship between mutual fund performance and investor fund flows, and the influence of investor fund flows on the performance of mutual funds. Our analyses are based on the data of mutual funds in Taiwan with three different frequencies that include monthly, quarterly, and yearly data. The methods we utilize to perform the analyses are those from Gruber (1996) and Edelen (1999). There are three main findings in this article: (1)During the sample period from 1996 to 2004, the evidence on the performance persistence of mutual funds in Taiwan is at best weak regardless of various risk-adjusted models and data frequencies. In sum, mutual funds in Taiwan do not perform persistently no matter how their performance is measured. (2)We are not able to discover a significant relationship between mutual fund performance and investor fund flows based on monthly data. This result is not consistent with that of Gruber (1996). However, this relationship becomes stronger if we look at quarterly data. In addition, the most interesting thing is that it seems that it is the quarterly stock market return that derives most of investor fund flows rather than the quarterly mutual fund performance itself. This result implies that the key factor for investors to decide whether to invest more capital into mutual funds is the overall market performance. In other words, the market sentiment may be the most importance factor that induces investors to purchase or sell mutual funds. (3) In contrast to the results of Edelen (1999), the liquidity-trading of fund managers induced by investor fund flows does not have a significant adverse effect on fund performance. Interestingly, the contemporaneous information-trading of fund managers has significant negative impact on fund performance while that in the previous month actually improves fund performance. Furthermore, the performance persistence normally lasts for two months but it diminishes when we incorporate both the liquidity-trading and information-trading of fund managers into the regressions.

Buscou-se identificar se os fundos que apresentaram maior captação líquida em seguida performam melhor do que os fundos de menor captação líquida. O efeito Smart Money foi identificado nos fundos de ações mesmo após ter sido controlado pelo efeito momentum. Nos fundos multimercados com renda variável e nos fundos de renda fixa não foi possível identificar tal fenômeno. / This work studies the Smart Money Effect, initially identified by GRUBER (1996) and ZHENG (1999), in the brazilian mutual fund industry in the period of 2001-2005. The objective was to verify if the funds with the highest net cash flows had a better performance in the following period than the funds with the lowest net cash flows. The Smart Money Effect was identified in stock funds, even after controlling by the stock return momentum phenomenon. In mixed funds and in fixed income funds it was not possible to identify such effect.

本研究探討2001年1月至2016年12月內所有以台股市場為標的之開放式股票型基金，透過多元迴歸模型與交易策略法深入的了解資金流量與過去和未來一期報酬率之間的關聯性，並從中探討台灣投資人的行為偏好。 透過多元迴歸模型與交易策略法可以發現代表台灣投資人投資偏好的資金淨流量變動率普遍有追逐過去績效表現優異之基金的傾向，接著探討資金淨流量變動率與未來一期報酬率的關聯後發現，台灣共同基金市場上當期資金淨流量變動率越高的基金，普遍在未來短期內所獲得的報酬率有較低的現象，然而隨著未來報酬期間的拉長，此現象便逐漸消失，最主要的解釋原因為台灣共同基金投資人普遍有追逐過去績效表現優異之基金的傾向，使過去績效表現較好的基金容易湧入過多的申購資金，而這些基金雖然在過去一期該基金經理團隊可以憑藉著自己所擅長的產業與個股經驗，挑選到具有成長潛力的投資標的，但隨著過去一期的優異表現，這些基金的投資組合持股價格已經來到相對高點，難以持續擁有良好的報酬表現，加上基金經理團隊手上仍握有許多等待投資的現金，最終可能迫使基金經理團隊必須開始涉入自己不熟悉的產業與個股，增加錯誤投資的機會而使績效表現變差，然而長期而言，該基金經理團隊仍可以憑藉著自己的專業投資能力，重新尋找到優良投資標的，消化過去湧入的投資資金，改善過去短期績效表現不佳的狀況。 / This study explored all open-ended equity funds targeting Taiwan’s stock market from January 2001 to December 2016. Through multiple regression model and trading strategy method, we got an in-depth understanding of the relationship between fund flows and both past and future returns, and the characteristics of the trading behavior of Taiwan’s investors were further investigated. By using multiple regression model and trading strategy method we found evidence that Taiwan’s investors have the tendency to chase mutual funds which had superior performance in the last period. Following this issue, we also found that funds with higher fund inflow generally had lower return in the short term time horizons, but the phenomenon would gradually disappear when the time horizons were extended. The main explanation of this phenomenon is that Taiwan’s investors generally have the tendency to buy mutual funds which gave superior return in the last period, so that funds with better performance in the past are prone to attract subscription. Although in the last period, these funds’ management team could rely on their own industrial and individual stock-picking experience, selecting those stocks with high growth potential. However, with an outstanding performance in previous period, stock prices in those fund’s portfolio had come to a relatively high point, so it’s hard to maintain good performance. With a vast sum of fund inflow, the management team may also be forced to invest in the industries or companies that they’re unfamiliar with, causing the possibility of wrong investment. However, when the time horizons were extended, the management team could digest the inflow of investment funds by rediscovering good investment targets and improve their fund performance.

台灣發行量加權股價指數在編製時並未調整現金股利的影響，不僅會低估實際的投資報酬率，以其作為標竿指標，在評估共同基金績效時，亦會產生標竿錯誤的問題。因此，本文將現金股利的再投資報酬納入，重新編製加權股價指數。實證結果發現，若自民國75年起調整現金股利之影響，則在民國89年10月31日時，股價指數由5544.18點調整為6419.83點，約增加1.16倍。以新指數重新衡量基金績效的結果，發現績效排名並無大幅度的改變，而且基金績效是否擊敗大盤的情形，受新指標的影響亦不大，此乃因近年來上市公司配息少，而且基金績效非常極端。但基於理論上的正確性，在計算投資報酬率及評估共同基金績效時，仍應以納入現金股利之加權股價指數為基礎，以降低因標竿指標錯誤所造成研究結果的偏誤，否則未來我國股票配息的情況及基金報酬率的特性若改變之後，以過去的方式評估績效將可能造成極大之偏差。 / The Taiwan Stock Exchange Market Weighted Index (TAIEX) is not adjusted for cash dividend. Since the TAIEX is commonly used for calculating the investment return of the Taiwan’s market and as the benchmark index for mutual fund performance evaluation, the investment return in Taiwan is underestimated and there is benchmark error in the evaluation of mutual fund performance. This paper adjusts the TAIEX by incorporating the effect of the reinvestment of cash dividend in the TAIEX. The beginning date of our adjustment is January 4, 1986. Since then until the end of October 2000, the adjusted TAIEX grew to 1.16 times of the unadjusted index. However, The mutual fund performance evaluated based on the adjusted index is insignificantly different from that based on the un-adjusted index. This is because mutual funds have extreme performance. Due to the small cash dividend paid out by the listed firms on the Taiwan Stock Exchange, the adjustment effect is not enough to overturn the evaluation of
