Investor sentiment and equity mutual fund performance in Brazil Sabrina Espinele da Silva Faculty of Economic Sciences, Federal University of Minas Gerais, Belo Horizonte, Brazil Simone Evangelista Fonseca Institute of Applied Social Sciences, Federal University of Ouro Preto, Mariana, Brazil Carolina Magda da Silva Roma Institute of Economic, Administrative, and Accounting Sciences, Federal University of Rio Grande, Rio Grande, Brazil Seung Hun Han School of Business and Technology Management, Korea Advanced Institute of Science and Technology, Daejeon, Republic of Korea, and Robert Aldo Iquiapaza Faculty of Economic Sciences, Federal University of Minas Gerais, Belo Horizonte, Brazil Abstract Purpose –Focusing on the Brazilian equity mutual fund industry, this study analyzes whether including the investor sentiment index in asset pricing models is important for explaining fund alpha. Design/methodology/approach –The investor sentiment index and risk factors in the Fama and French (1993) and Carhart (1997) models were estimated, the risk-adjusted performance of a sample of equity mutual funds in Brazil was evaluated, and a United States (US) sample was included for a complementary perspective. The sample period spans 2010–2019 for Brazil and 2010–2018 for the US. Findings –The results contrasted with those evidenced in the US, where the sentiment index was an important factor in explaining the probability of alpha occurrence, especially in the case of winner funds, defined as those exhibiting a positive and statistically significant alpha at the 5% level. Overall, the findings suggest that, in the Brazilian market, pricing models incorporating investor sentiment as an additional factor fail to adequately capture the outperformance probability of equity mutual funds. These results suggest that the factors influencing fund performance may differ between the two countries and highlight the relevance of developing more suitable investor sentiment indicators for emerging markets. Originality/value –This study examines the impact of the sentiment index on the performance of equity mutual funds in Brazil, specifically its influence on alpha generation.

1. Introduction For decades, one of the most widespread ideas in the finance literature has been that investors are rational, and therefore, stock market prices should reflect the fundamental value of future cash flows. However, several studies suggest that these assumptions do not fit the real world and that market prices are indeed affected by investor emotions and expectations (Lee et al., 1991;Baker and Wurgler, 2006,2007). Moreover, a series of studies indicate that investor sentiment affects the capital market (Brown and Cliff, 2004;Baker and Wurgler, 2006,2007; Bandopadhyaya and Jones, 2006;Yoshinaga and Castro Junior, 2012;Corredor et al., 2013; Firth et al., 2015;Bu, 2020a,b;Bitencourt and Iquiapaza, 2024). Investor sentiment can be defined as the expectations of asset returns that their fundamentals cannot explain (Lee et al., 1991). It is also related to pessimism or optimism regarding the stock market in general and the propensity to speculate (Baker and Wurgler, 2006,2007). In this sense, sentiment has been widely recognized to affect the overall financial market (Cheong et al., 2017;Paraboni et al., 2018). Nevertheless, only recent studies have focused on the possible effect of investor sentiment in the mutual fund industry, specifically, on how it can affect managers’ strategies and the performance delivered to shareholders (Bu, 2020a,b;Wang et al., 2020,2021). In addition, most of these studies show the influence of sentiment on the Chinese and US markets. Recently, some researchers have investigated the estimation and influence of the investor sentiment index on the Brazilian market (Yoshinaga and Castro Junior, 2012;Xavier and Machado, 2017;Miranda and Machado, 2018;Santana et al., 2020;Bitencourt and Iquiapaza, 2024). However, none of these studies have considered the mutual fund industry, despite its importance in the Brazilian market. Additionally, notwithstanding this evidence, Brazilian studies are continuing to progress toward the development of the sentiment index and its effects on the market (Xavier and Machado, 2017;Miranda and Machado, 2018;Santana et al., 2020). In this sense, the objective of this study is to investigate the effect of investor sentiment on mutual fund performance (occurrence of fund alpha) in the Brazilian mutual equity fund industry. According to benchmark models, in particular, the Capital Asset Pricing Model (CAPM) and the Fama and French (1993) and Carhart (1997) models, a positive alpha implies that the fund has outperformed the market, as alpha is measured by the difference between a fund’s actual return and its expected performance according to a benchmark model (Jensen, 1968;Bu, 2020b). By definition, a positive fund alpha should occur only occasionally because of the efficient market hypothesis, which states that it is not possible to beat the market consistently (Fama, 1970). However, positive fund alphas are regularly documented (Bu, 2020a,b), suggesting that some important factors might be missing in standard benchmark models (Bu, 2020a). Therefore, investor sentiment is used as one of the possible missing factors, following the approach of Bu (2020b) and adapted it to an emerging market, such as Brazil. Baker and Wurgler (2006,2007) state that no perfect proxy for investor sentiment exists, but propose a practical approach for its estimation. This approach was adapted by Yoshinaga and Castro Junior (2012), and other studies proposed an investor sentiment index for Brazil, which was used in this study. For example, Miranda et al. (2018) estimate the investor sentiment index for Brazil without considering turnover because it is affected by the frequency of negotiations. Santana et al. (2020), who argue that sentiment is associated with financial decisions and accounting choices, suggest that it influences firms’ accruals, which, in turn, influences share pricing in the Brazilian market. Consequently, discussions about the effects of sentiment on the Brazilian market have gained increasing importance in research on asset pricing models. Equity mutual funds in Brazil were analyzed adopting a comparative approach and incorporating data from the US as a reference point. Following the methodology established by Bu (2020b), the analysis spans a decade, covering the period from 2010 to 2019 for Brazilian funds and from 2010 to 2018 for US funds. The terminal date for the US data is dictated by the last available year for the Baker and Wurgler sentiment index, which serves as a critical metric in this assessment. The obtained results were the same as Bu (2020b) concerning the US; in other words, the sentiment index was found to be a key factor in capturing the JEFAS 30,59 190
outperformance probability of equity funds. However, the main results for Brazil suggest that benchmark models accounting for investor sentiment as an additional factor do not adequately capture the outperformance probability of equity mutual funds. In addition, the results were consistent for estimating the Brazilian sentiment index, although it is important to note that a standardized set of variables for this estimation has not yet been established. The findings underscore the importance of further research exploring variables that predict investor sentiment in emerging markets, as they suggest the need to develop more appropriate sentiment indices for these markets. This aligns with other studies that have analyzed investor sentiment in the stock markets of developing countries (Anand et al., 2021;Torre-Torres et al., 2021). The remainder of this paper is organized as follows: Section 2 discusses the previous studies that helped us achieve the study goals. Section 3 describes the methodology used in this study. Section 4 presents the study results. Section 5 presents the discussion, and Section 6 offers the conclusion of the paper. 2. Theoretical foundations and related literature This section discusses studies on investor sentiment and asset pricing models in relation to mutual funds in both the Brazilian and overseas markets. 2.1 Investor sentiment To determine whether the mutual fund industry takes market sentiment into consideration, Massa and Yadav (2015) investigated the mutual fund industry in the US over the period 1984–2005. They argued that mutual fund managers could use market sentiment strategically to improve their performance and indirectly attract more flows into the fund. Furthermore, they argued that funds with low exposure to sentiment tended to follow more particular investment strategies and those of active fund managers, specifically, bold and traditional strategies for allocating fund resources in response to optimism and pessimism expressed by changes in sentiment during the period. Moreover, their results showed that the funds in which managers invested more—low-sentiment-beta stocks—attracted more significant investor flows. Jiang and Yuksel (2019) studied a sample of actively managed US mutual funds over the period 1993–2014 to check for differences in the decision-making process of investors regarding their allocation of money in some mutual funds, depending on sentiment periods (high or low). The results showed that the preference of mutual fund investors for certain fund characteristics changed depending on the sentiment period. They found that mutual fund investors tended to pay more attention to past performance, expenses, and fund visibility when sentiment was high. In addition, the effect of sentiment was more pronounced among retail fund investors than among institutional investors. By analyzing the relationship between investor sentiment and mutual fund performance, Bu (2020a,b) discussed how investor sentiment affected a mutual fund’s alpha. He explained that the probability of outperforming funds increased with investor sentiment and claimed that investor sentiment was a missing factor in the benchmark models that researchers tended to use to estimate fund performance. Wang et al. (2021) observed how mutual fund managers reacted to market sentiment in the Chinese mutual fund industry. They showed that mutual funds followed the sentiment-catering strategy; that is, they attracted new flows into funds based on investors’ enthusiasm for popular stocks, and this did not necessarily provide better performance to the fund/investor. Furthermore, these funds tended to incur greater risks when rebalancing their portfolios. Thus, there is evidence of an agency problem in mutual funds, with managers acting in their own interests rather than in line with the investors’ objectives. Santana et al. (2020) pointed out that this agency problem has also occurred in Brazil. They investigated the relationship between the sentiment index and the discretionary accruals of publicly traded companies and found, specifically in a Journal of Economics, Finance and Administrative Science 191
separate analysis of periods of low and high sentiment, that managers tended to increase and reduce accruals, respectively, after changing the sentiment index of each time course. In another study, Wang et al. (2020), who also studied Chinese mutual funds between 2009 and 2016, uncovered other evidence on the sentiment strategies of mutual funds. The main results showed a negative relationship among performance, fund risk-taking, and the sentiment proxy (FLOW). They argued that fund managers tended to minimize risk-taking when sentiment was high and contended that there was evidence regarding the dumb money effect. The study’s findings indicate that funds contribute to stabilizing the financial market because enthusiasm for investing in funds tends to intensify managers’ risk aversion, which reduces risk-taking. 2.2 Asset pricing models Asset pricing models emerged in the 1960s, starting with the Capital Asset Pricing Model (CAPM). This model assesses the performance of investment assets based on the market risk. This risk is the main explanatory factor for the asset returns relative to the market returns and the returns of the risk-free asset (Sharpe, 1964;Lintner, 1965;Mossin, 1966). The CAPM postulates a linear relationship between returns and systemic risk and is based on the premises of investor rationality and market balance. The CAPM was estimated using a simple linear regression represented by Equation (1). The Ordinary Least Squares (OLS) were used, estimated from asset returns and the difference between the average market returns and the risk-free asset returns. An asset’s exposure to market risk represents the investment premium estimated according to the market risk. Ri¼αþβi�Rm�Rf�(1) As an alternative to the CAPM, in which the risk estimation process is multiple and composed of macroeconomic factors, Fama and French (1993) proposed a three-factor model. They argue that, in addition to market risk, we must also consider the influences of size (SMB) and the value measured in the book-to-market (HML) on asset performance, as shown in Equation (2). In addition, for the evaluation of investment funds, Carhart (1997) added a fourth factor, the moment factor (MOM), to the three-factor model. This approach was based on Grinblatt and Titman (1993), who assessed the persistence of abnormal fund returns. This factor expresses the persistence of the return on assets over time, and the model is shown in Equation (3). Ri¼αþβi�Rm�Rf�þsiSMB þhiHML (2) Ri¼αþβi�Rm�Rf�þsiSMB þhiHML þmiMOM:(3) Recently, Fama and French (2015,2016) defended a five-factor model. They argued that the pricing process should consist of the three-factor model and the factors of investment (RMW) and profitability (CMA), as shown in Equation (4). Here Riis the excess of a fund’s returns estimated by the difference between the returns of fund iand the risk-free asset, Ri−Rf. Overall, studies appraising Brazilian fund performance frequently use the CAPM and threeand four-factor models to show the statistical significance of the effect of these factors on asset performance (Borges and Martelanc, 2015;Nerasti and Lucinda, 2016;Maestri and Malaquias, 2018;Fernandes et al., 2018;Silva et al., 2018,2020).

3. Methodology The Brazilian fund sample comprised 303 active equity mutual funds. Category selection followed the new classification of the Brazilian Financial and Capital Markets Association (Associaç~ ao Brasileira das Entidades dos Mercados Financeiro e de Capitais [ANBIMA]). Indexed, foreign, and sectoral investment funds were not considered because of the particularities of these classes. The sample period spans from January 2010 to December 2019. Only funds with complete return data were considered, as did Bu (2020b). Fund data were collected from SI ANBIMA. The investor sentiment index and the risk factors for the pricing models were estimated monthly for the Brazilian market. Data for estimating the risk factors were obtained from Economatica, following the procedures outlined by Fama and French (1993) and Carhart (1997). For the sentiment index, some data were collected from the Brazilian stock exchange (Brasil, Bolsa, Balc~ ao - B3) and the Securities and Exchange Commission (Comiss~ ao de Valores Mobili� aros [CVM]), while the remaining data were sourced from Economatica. The Brazilian investor sentiment index was estimated using four variables: Number of Initial Public Offerings (NIPO), Individual Investor Participation (PartInvInd), Premium for Dividends (PDiv), and the High-Low Ratio (AD). NIPO was measured as the average of IPOs and Follow-ons during the previous twelve months. PartInvInd refers to the percentage of individual investors’ participation in B3’s monthly transactions. For PDiv, companies were classified as either dividend payers or non-payers based on whether they paid dividends greater than zero, as reported in their financial statements. PDiv was then calculated by taking the difference in the logarithms of the market-to-book ratio for each group. The AD is the ratio of the highest to lowest stock prices over the past twelve months. These variables were selected based on previous studies (Baker and Wurgler, 2006,2007;Yoshinaga and Castro Junior, 2012;Xavier and Machado, 2017;Miranda and Machado, 2018;Santana et al., 2020). It is important to note that the discount rate variable, originally used in Baker and Wurgler’s index, was not included due to its unavailability in Brazil (Yoshinaga and Castro Junior, 2012). The turnover variable was also excluded because of the high frequency of institutional investor trades, which, according to Wurgler’s website, no longer reflects investor sentiment. In the estimation of sentiment, the variables NIPO and PDiv were considered contemporary, and the variables PartInvInd, and AD lagged. This choice between the variable and its lag depended on its correlation with the first component of the principal component analysis (PCA), a method of estimating sentiment. In addition, the variables were orthogonalized concerning the macroeconomic variables (inflation, GDP growth, employment level, consumption level, and crises). The variables were obtained from the Brazilian Institute of Geography and Statistics (IBGE), the Institute for Applied Economic Research (IPEA), and the National Bureau of Economic Research (NBER). For orthogonalization, the residuals of the linear regression of each variable of the sentiment index with the set of macroeconomic variables were used, a common procedure in the sentiment literature (Baker and Wurgler, 2006,2007;Yoshinaga and Castro Junior, 2012; Xavier and Machado, 2017;Miranda and Machado, 2018;Santana et al., 2020). All variables were validated using PCA, meaning only eigenvalues greater than one were validated (Yoshinaga and Castro Junior, 2012;Firth et al., 2015;Xavier and Machado, 2017;Miranda and Machado, 2018;Santana et al., 2020). In fact, the percentage of variation explained by the first component was 59%, higher than some studies pointed out; for example, Miranda and Machado (2018) calculated a proportion of 49%, like that calculated by Yoshinaga and Castro J� unior (2012). To estimate the sentiment index, seven steps were followed, summarized as follows: (1) Estimation of variables and lags, 12-month lagged variables. (2) Validation of the database structure for PCA using Bartlett’s test and the Kaiser-MeyerOlkin (KMO) test. Journal of Economics, Finance and Administrative Science 193
(3) PCA and evaluation of the correlation between the variables and the first principal component. (4) Selection of contemporary NIPO and PDiv; PartInvInd, and AD lagged. (5) Orthogonalization with the macroeconomic variables of inflation, GDP growth, crisis, and employment and consumption levels. (6) Validation of new data using Bartlett’s sphericity test and the Kaiser-Meyer-Olkin (KMO) test. (7) Estimation of the sentiment index using PCA and appropriate variables. For data validation, Bartlett’s and the KMO tests were used, which are complementary techniques of multivariate statistics that ensure the use of PCA and the usefulness of the results. Bartlett’s test validates the correlation structure among the variables, while the KMO index evaluates the magnitude of this correlation (Johnson and Wichern, 2007;Shrestha, 2021; Fonseca, 2022). Prior to orthogonalization, Bartlett’s test yielded a test statistic of 1,182.50 (with ap-value of zero), indicating the rejection of the null hypothesis that PCA would not be appropriate. The KMO test was 0.69, also considered valid, as values closer to one indicate greater appropriateness of the technique for the data. After orthogonalization, the tests were reapplied, and the results remained consistent: Bartlett’s test produced a statistic of 350.89 (with ap-value of zero), and the KMO index was 0.60, maintaining the previously identified adequacy. In this study, the CAPM and threeand four-factor models are named CAPM, FF, and FFC, respectively. They were estimated with and without including the Sentiment Index (Sent) with the time series. Heteroscedasticity and autocorrelation tests were performed using residuals, and when necessary, the residual covariance matrix was corrected, as shown by MacKinnon and White (1985). The regressions were estimated for all periods and three subperiods: Jan. 2010 to Dec. 2012, Jan. 2013 to Dec. 2015, and Jan. 2016 to Dec. 2019. The results served as a basis for calculating the probability of superior fund performance (Bu, 2020b). Outperformance probability reflects the probability that the alphas are positive and significant in the models divided by the alpha’s total. Specifically, the coefficients of the winner funds (the winner funds included all funds with positive alphas that were statistically significant at the 5% level) were evaluated, sentiment was classified into high and low quintiles for analysis of the fund alphas, and the models for each quintile were estimated. To complement the analysis of Brazil, a sample of US mutual funds was also collected for comparison, covering a period similar to the Brazilian funds. The US data were gathered as follows: mutual fund information was sourced from the Center for Research in Security Prices (CRSP) database, specifically the survivor-bias-free (Elton et al., 1996) mutual fund database. The sample includes US equity funds from the EDYG class. Additionally, due to the available years for the sentiment index, 2019 was not included. For the US sample, the investor sentiment index was obtained from the Wurgler website (http://people.stern.nyu.edu/jwurgler/ ), and the risk factors were obtained from the Kenneth French website (https:// mba.tuck.dartmouth.edu/pages/faculty/ken.french/data_library.html). 4. Empirical findings 4.1 Analysis of descriptive statistics on fund returns, sentiment index, and risk factors Table 1 presents the descriptive statistics of the variables used to estimate the models. It was observed that the average and median values of the measured statistics were very close. This indicates symmetry in the distribution of the values. In addition, considering the coefficient of variation with this standardized measure of distribution, it was observed that the funds presented great variation in monthly returns throughout the series. Similarly, funds are presented as mean and median positive returns in the sample period. Furthermore, the mean and median of the sentiment index were negative, showing that Brazilian investors were generally pessimistic about the Brazilian market throughout the period 2010–2019. JEFAS 30,59 194
Figure 1 presents the movements of the sentiment index and the monthly market excess returns (RMRF). The sample period was from January 2010 to December 2019. The sentiment index was multiplied by five to facilitate comparison. Figure 1 shows the monthly distributions of the market premium and investor sentiment index in the Brazilian market. According to the Organization for Economic Co-operation and Development (OECD), recessions occurred in the American market from May 2012 to February 2014, May 2015 to April 2017, and August 2018 to December 2019. These periods are associated with significant fluctuations in the Brazilian market and, like Bu (2020b) attests to the US case, do not respond quickly to the variations in the sentiment index. In the case of Brazil, the responsiveness of the sentiment index to market fluctuations was determined to be too low. 4.2 Performance and effects of the sentiment index in the Brazilian market First, the outperformance probability of funds was estimated, that is to say, the probability of achieving a positive alpha that is statistically significant at the 5% level, using the standard Table 1. Descriptive statistics of the variables, Brazil Mean Standard deviation Coefficient of variation Minimum Median Maximum Return 0.874 4.963 5.677 �33.60 0.743 33.05 Sent �0.440 1.122 �2.549 �2.980 �0.567 3.349 Risk free 0.008 0.002 0.275 0.004 0.008 0.012 RMRF �0.002 0.057 �30.253 �0.126 �0.004 0.158 SMB �0.001 0.039 �58.946 �0.134 �0.004 0.120 HML �0.017 0.052 �3.045 �0.133 �0.017 0.122 Mom 0.020 0.050 2.487 �0.133 0.021 0.132 Note(s): Table 1 presents the descriptors of the variables that served as the basis for the measurement of pricing models. RMRF refers to ðRm−RfÞ. The fund sample includes 306 mutual funds. The sample period ranges from January 2010 through December 2019 (monthly return data in %) Source(s): Authors’ own work Figure 1.

benchmark models CAPM, Fama and French (1993) (FF), and Carhart (1997) (FFC). The sample was also divided into subperiods to check for the effect of the market state. Table 2 presents the test results. Our results demonstrated that a higher probability of outperforming occurred when alphas were measured based on the CAPM model. As Table 2 shows, this probability is 29.04% against the 14.52% of the 3-factor model and 7.92% of the four-factor model for the entire period. In contrast, the outperformance probabilities decrease sharply when the estimation of alphas is based on the FFC model, suggesting that momentum is an important factor to consider for mutual fund performance analysis, as noted by other authors (Carhart, 1997; Borges and Martelanc, 2015;Nerasti and Lucinda, 2016;Maestri and Malaquias, 2018; Fernandes et al., 2018;Silva et al., 2020). By subperiod, Table 2 shows that the outperformance probabilities vary from 27.06% to 6.60% using the CAPM, from 6.93% to 1.98% using the FF model, and from 3.96% to 1.65% using the FFC model. These results indicate that the FFC model best explains fund performance even for shorter sample periods. Furthermore, the lowest outperformance probability was in period 3 (2016–2019). Therefore, all changes in outperformance probabilities across periods indicate that market states might play a role in the probability of abnormal fund returns occurring. Subsequently, the outperformance probabilities of funds were estimated using the standard benchmark models (CAPM, FF, and FFC) adjusted for investor sentiment. The results presented in Table 3 suggest that adding the sentiment index to a benchmark model can substantially increase the outperformance probability, excluding the four-factor model in the entire period, the CAPM model in the first subperiod, and all the models in the 2016–2019 subperiod. The period from 2016 to 2019 was marked by great uncertainty in Brazil. In 2016, President Dilma Rousseff was impeached and several politicians were arrested as a result of Operation Table 2.
