The purpose of this paper is to investigate relative portfolio performance between sin stock returns and faith‐based returns.

Similar to Hong and Kacperczyk, Jensen's alpha was utilized to conduct tests along with three asset‐pricing models and rolling regression technique to reveal that faith‐based and sin betas move in opposite directions during most of the sample period.

Norm‐neglect was found, in that Jensen's alpha is positive and significant for the sin portfolio. Further, evidence in favor of norm‐conforming investor behavior was found, where Jensen's alpha is negative and significant for the faith‐based portfolio. These findings provide evidence that the sin portfolio outperforms the faith‐based portfolio relative to the market. A rolling regression technique reveals that faith‐based and sin betas tend to move in opposite directions during most of the sample period. The evidence suggests that faith‐based beta has an average estimated beta of one, mimicking the market. The sin portfolio, however, has an average estimated beta of one‐half. Finally, the reward‐to‐risk measure, Sharpe ratio, is statistically higher for the sin portfolio relative to the faith‐based portfolio.

This paper contributes to the literature in the following distinct ways. First, three asset‐pricing models are estimated to examine Jensen's alpha for sin and faith‐based portfolios. Second, a rolling regression procedure is used to examine the dynamic behavior relative to the market of the sin and faith‐based portfolios. Third, use is made of the Jobson and Korkie test, which allows for statistical comparisons of Sharpe ratios. Lastly, daily instead of monthly data and a different sample period are used to examine the research questions posed in this study.

This paper aims to analyse the differences in financial performance portfolios between sustainable and non-sustainable firms through the use of portfolio theory and OptQuest algorithms from 2007 to 2013.

The sample consists of 1,078 firms from 15 Organisation for Economic Cooperation and Development countries. A maximisation weighted ratio is estimated by applying OptQuest algorithms to measure the portfolio performance considering a fuzzy Jensen’s alpha and the percentage of the portfolio’s performance that exceeds the market.

The results show a similar financial performance in sustainable portfolios (SP) and non-SP, but considering the uncertainty, the performance in sustainable firms was better than that of non-sustainable ones. Uncertainty was reduced, as it passed the beginning of the crisis from 2008-2009 to 2012-2013.

The main limitation is the different assessments of sustainability indexes in each of the countries.

The results help investors assess their decisions in an uncertain economic environment and allocate their investment in not only financial terms but also social character.

Countries with higher financial performances in SP show the efficiency in their legal environmental regulations. On the other hand, the degree of uncertainty is lower in the SP than non-SP, suggesting that sustainable firms in financial crisis could be more responsible in social claims such as good working conditions.

This study contributes to existing research in two ways. First, the paper studies corporate social responsibility by different continents and countries in an uncertain economic timespan. For this, the legal, cultural and socioeconomic divergences and convergences were explored. Second, the research presented an analysis of the financial performance differences between sustainable and non-SP by applying a hybrid methodology with fuzzy regression and OptQuest algorithms.

This paper aims to study manipulation and performance persistence in equity mutual funds. To this end, Manipulation-Proof Performance Measure (MPPM) and Doubt Ratio, along with a number of current performance measures are used to evaluate the performance of equity mutual funds in Iran.

The authors investigate performance manipulation by 1) comparing the results of the MPPM with the current performance measures, 2) checking the Doubt Ratio to detect suspicious funds. Additionally, the authors investigate performance persistence by forming and evaluating portfolios of the equity mutual funds at several time horizons.

The authors conclude that there is no evidence of performance manipulation in the equity mutual funds. Additionally, when comparing the performance of the upper (top) tertile portfolios and the lower tertile portfolios, in all of the studied 1, 3, 6 and 12-month horizons, the authors find performance persistence in the equity mutual funds.

To the best of the authors’ knowledge, this research is the first study to investigate the performance manipulation in the Iranian equity mutual funds, and also is the first study in Iran that uses the MPPM and the Doubt Ratio in addition to a number of current performance measures to investigate the performance persistence in the equity mutual funds at several time horizons.

This paper aims to undertake a comprehensive comparative analysis of Sharīʿah-compliant equity investments (SCEIs) and their non-Sharīʿah counterparts, in India, conditioning for investment horizon and market volatility. Indirectly, it also investigates for time varying performance of SCEIs, and explicitly analyses the unsystematic risk and related adequacy of returns.

Testing for statistical significance of differences in risks and returns; analysing portfolio performance using conventional metrics, information ratio, and Jensen's Alpha; Estimating returns due to stock selection and market timing using Fama’s Net Selectivity and Treynor and Mazuy’s Models.

SCEIs in India do not significantly differ in their total risks and returns compared to their conventional counterparts. While their risk is lower in the monthly and quarterly investment horizons, their Jensen’s Alphas are positive only in the annual investment horizons. These findings hold, when market volatility is low. Market timing wipes out the superior returns that exist due to stock selection in SCEIs.

Being Sharīʿah-compliant is beneficial only in longer investment horizons. Asset selection, not co-movement with the market, is key to excess returns to compensate for risks due to inadequate diversification. However, only cautious market timing can conserve them.

Though investors are not better-off in choosing ethical investments, they are not worse-off either. Being Sharīʿah-compliant is rewarding during less volatile markets.

This paper extends international literature on SCEIs, with evidence on the impact of investment horizon and market volatility on their returns and risks. Further, this paper is also a comprehensive analysis of Indian SCEIs, broadening the empirical evidence on a significant, non-Islamic and emerging market.

The purpose of this paper is to appraise the risk‐adjusted performance of international mutual funds using measures generated by the optimized variance (OV), and to promote ability of portfolio managers and investors in making logical decisions.

This study appraises the performance of 65 international mutual funds via the optimized risk‐adjusted measures during monthly period of 2001‐2010. Using 65 linear programming models, the OV is calculated to optimize the standard deviation of any funds. Then, another model is run to get the OV of market index. Consequently, seven optimized performance measures namely Treynor, Sharpe, Jensen's alpha, M‐squared, information ratio (IR), MSR, and FPI along with the optimized leverage factor are proposed to evaluate the performance of these mutual funds. Finally, the optimized measures are used to evaluate the funds during pre and post‐crisis periods in order to compare the funds' performance over the crisis periods.

The empirical evidence detects which OV, as measured by the Markowitz's linear programming model, is an important determinant in the performance evaluation measures. Using OV statistic and also its standard deviation, this paper shows that new optimized measures are mostly over‐performed rather than the benchmark index; in addition these optimized measures have close correlation with the conventional performance measures. The evidence shows that the average of the optimized measures during crisis has the lowest performance in comparison with other research periods. The results therefore highlight the importance of using the new optimized measures along with the conventional measures in the evaluation of mutual funds' performance.

It can be worthwhile to compare the optimized measure and also the conventional measures in identifying their superior measures.

The result of this study can be directly used as initial data to make decision by investors and portfolio managers who are seeking the possibility of participating in the global stock market through international mutual funds.

This paper is one of the first studies that optimizes the variance of return for any fund to suggest four optimized measures of Sharpe, IR, MSR, and FPI, and then proposes a new linear programming model to get OV of market index in introducing four optimized new measures of Treynor, M‐square, Jensen's alpha, and leverage factor.

This paper aims to evaluate the risk‐adjusted performance of Malaysian mutual funds using optimized drawdown risk measures (ODRMs) based on modern portfolio theory, and to represent the results in a manner which is easily understood by average investors and portfolio managers.

This study evaluates the performance of 70 Malaysian mutual funds using risk‐adjusted returns during 2000‐2011. The ODRM is primarily calculated by 70 linear programming models, consequently seven new optimized risk‐adjusted performance measures including Sharpe, Treynor, M‐squared, Jensen's alpha, information ratio (IR), MSR, and FPI are proposed to evaluate these funds.

The results of this study have several implications. First, the ODRM can be an alternative risk measure to optimize the selection of mutual funds. Second, it proposes new seven optimized performance measures of Sharpe, Treynor, M‐square, Jensen's alpha, IR, MSR, and FPI. These measures help fund managers to evaluate the performance of Malaysian mutual funds optimally. Third, No‐Islamic funds have the upper performance than Islamic funds based on the results of optimized measures and robustness tests. Fourth, the majority of surveying funds over‐perform the benchmark indexes.

The research evidence reported by this study can be utilized as input in the process of decision making by small and average investors and portfolio managers who are seeking the possibility of participating in Malaysian stock market by mutual funds.

This paper is the first study that optimizes the drawdown risk measure to evaluate the performance of Malaysian mutual funds and propose seven optimized measures, Sharpe, Treynor, M‐Square, Jensen's alpha, IR, MSR, and FPI.

This paper aims to evaluate the risk‐adjusted performance of US‐based international equity funds using objective statistical measures grounded in modern portfolio theory, and to present the results in a manner which is easily understood by the average investor.

This study evaluates the performance of 50 large US‐based international equity funds using risk‐adjusted returns during 1994‐2003. In particular, a relatively new risk‐adjusted performance measure (M squared), first proposed by Franco Modigliani and Leah Modigliani in 1997, is used to evaluate these equity funds.

The empirical results show that the funds with the highest average returns may lose their attractiveness to investors once the degree of risk embedded in the fund has been factored into the analysis. Conversely, some funds, whose average (unadjusted) returns do not stand out, may look very attractive once their low risk is factored into their performance.

It may be worthwhile to examine the effects of factors such as fund manager compensation, service fees, corporate governance metrics, and overweighting in risky countries/regions on the performance of international equity funds.

The evidence presented in this study can be used as input in decision making by investors who are exploring the possibility of participating in the global stock market via international equity funds.

This paper is one of the first studies that apply the new M squared measure to evaluate the performance of international equity funds using both domestic and international benchmark indices. Various other performance metrics are also utilized including Sharpe and Treynor measures, and Jensen's Alpha.

When a fund manager leaves, the investment strategy of the fund changes or remains the same. The departing fund manager's resignation is either forced or voluntary. The study investigates the relationship between the portfolio manager's transition and the fund's investment strategy and how the change affects the mutual fund returns in the subsequent period.

The authors examine 148 fund manager changes in India between April 2005–March 2018 using three performance measures: abnormal return (fund return minus benchmark return), Jensen's alpha and Carhart four-factor alpha. The analysis includes an event study methodology, followed by a two-step Fama–MacBeth regression approach.

Contrary to the previous studies conducted in the developed markets, the authors find that fund performance improves irrespective of whether the fund manager change is forced or voluntary. The outperformance after the fund manager's exit is significant for funds belonging to the larger fund families.

In the context of investment management, the authors provide a conceptual framework to understand the effect of fund manager exit on mutual fund performance. The authors substantiate their arguments with empirical evidence. To the best of the authors' understanding, this is the first research to examine the effect of changing mutual fund managers in an emerging market setting.

This paper aims to examine performance of firms with a negative second-day return after the Initial Public Offering (IPO) relative to stocks with a positive second-day return after the IPO. Loughran and Ritter (1995) document that firms which have done an IPO or an SEO underperform similar firms over three- and five-year investment horizons. Loughran and Ritter (2002) also document that firms that go public “leave money on the table”, with this amount being almost twice as large as the fees paid to the investment banks.

The study’s null hypothesis is that stocks with a negative return on the second day of the IPO perform better than firms with a positive return on the second day of the IPO. The authors estimate the second-day return based on first- and second-day closing prices from the Center for Research in Security Prices, and they use a regression model and Jensen’s alpha to test the hypothesis.

The authors find evidence that rejects the paper’s working null hypothesis of superior performance of negative second-day return IPO firms relative to positive second-day return IPO firms in the three-year and five-year period samples. They fail to find statistically significant evidence in the entire period samples which suggest that negative second-day return IPO firms perform similarly to positive second-day return IPO firms.

The findings in this study raise interesting questions with regards to the ideas developed by Loughran and Ritter (2002) and the “money left on the table”. These findings are of interest to both entrepreneurs and investment bankers who advise them during the underwriting process. If there is not a benefit in terms of IPO performance to investors, then the question becomes – shouldn’t owners possibly consider actually “taking money from the table”. After all, the return to investors will be the same either way but if entrepreneurs make more money at IPO they would be motivated to start more companies in the future.
