GÜÇLÜ, F., & ŞEKKELİ, F. E. (2020). PERFORMANCE ANALYSIS AND COMPARISON OF ISLAMIC AND CONVENTIONAL STOCK MUTUAL FUNDS IN TURKEY . Business & Management Studies: An International Journal, 8(5), 4463-4486. https://doi.org/10.15295/bmij.v8i5.1659



Performance, selection, and market timing abilities of stock mutual funds' managers are investigated in literature by plenty of researchers. Last three decades, Islamic investments have shown extraordinary progress. Therefore, Islamic investment instruments attracted researchers' attention in this area. In the literature, many studies were conducted to compare the performance of Islamic and conventional stock mutual funds. According to findings of Alam and Rajjaque (2010), Hoepner et al. (2011), Mansor and Bhatti (2011), Rubio et al. (2012), Shah et al. (2012), Ashraf (2013), Omri et al. (2019), Climent et al. (2020), Aksu and Aytekin (2020), Islamic funds show better performance comparing their conventional counterparts. The findings of Hassan et al. (2010) Hassan and Girard (2012), Reddy et al. (2017), Naqvi et al. (2018) reveal no significant differences in the performance of Islamic and conventional mutual funds. Hovewer, Uysal, and Adalı (2018), Zouaoui (2019) find that performances of conventional mutual funds are better than Islamic ones.


The purpose of this study is to compare the performance of conventional and Islamic stock mutual funds traded in the Turkey capital markets and to reveal the selection and market timing abilities of fund managers. The study provides useful information for investors and fund managers about the performance and riskiness of Islamic stock mutual funds.


When reviewing the existing literature about Islamic mutual funds in Turkey, most of the studies conducted are focus on Islamic pension funds. Therefore, this study extends the literature in terms of Islamic stock mutual funds.


This study adopts a quantitative analysis to compare the performance of Islamic and conventional stock mutual funds.


The research problem of this study is to determine how different the performances of Islamic stock mutual funds are from their conventional counterparts.


The data set used in this study was obtained from the Thomson Reuters Eikon database. The data covers 5 years from November 2015 to August 2020.


This study performs commonly used methods in the literature to measure fund performances as Sharpe Ratio, Treynor Ratio, Modigliani (M2) measure, Information Ratio, and Jensen Alpha (α). Besides, determining fund managers' market timing ability Treynor and Mazuy (1966) quadratic regression model is used.


According to risk-adjusted performance measurement results, TKF has the highest performance except for Information ratio. Islamic stock mutual fund ZPE's performance is moderate when compared to conventional funds. Jensen alpha results show that most of the funds have statistically insignificant alphas, including ZPE. TKF still has the highest alpha, which indicates that fund managers are good at selecting stocks. When looking at beta results in the systematic risk measure, most of the funds have lower betas than the market. TKF has the lowest beta. Islamic fund ZPE's beta is 0.8105, which is lower than the rest of the funds except TKF and ST1. Treynor and Mazuy (1966) model results indicate that only one stock mutual fund (EID) has a statistically significant upsilon parameter.


The findings of this study support the works of Hassan et al. (2010) Hassan and Girard (2012), Reddy et al. (2017), Naqvi et al. (2018) which reveal no significant differences in the performance of Islamic and conventional mutual funds.

    • RESULTS of the ARTICLE      

When the results are evaluated as a whole, it can be stated that Islamic stock mutual funds have similar performance to their conventional counterpart, and there is no significant difference between them. Besides, it can be said that Islamic stock mutual funds contain a lower risk. Thus they can be considered as safe investment vehicles and preferred by risk-averse investors.


Future studies could extend the scope of this study by including other Islamic stock mutual funds that are included in TEFAS and whose data do not cover the five years. Furthermore, future research could also be conducted to determine international diversification benefits of Islamic stock mutual funds by including cross country data.

  • LIMITATIONS of the ARTICLE                  

The main limitation is that the samples of Islamic and conventional stock mutual funds were from one market. Furthermore, only one Islamic stock mutual fund is included in the study due to other İslamic stock mutual funds cover less than five years.
