The aim of this study was to use the Single-Valued Neutrosophic Set (SVNS) to analyze 58 mutual funds, traded at the Istanbul Stock Exchange, under incomplete, indeterminate and inconsistent information. To this end, the performance of the funds was first evaluated using the most commonly preferred criteria like the Morningstar rating, Sharpe ratio, Treynor ratio, and Jensen ratio. Following these criteria, SVNS based entropy was used to rank the funds. The results of the entropy weights revealed Morningstar rating to be the most important evaluation criterion followed by Treynor, Sharpe and Jensen ratios respectively. Yapı Kredi Asset Management Foreign Technology Sector Equity Fund was found to be the most successful fund, while İş Asset Management BIST Technology Capped Index Share Fund (Equity Intensive) Fund was the least successful fund.

Thesis (M.A.) from the year 2014 in the subject Business economics - Investment and Finance, grade: 7.5, Maastricht University, language: English, abstract: The following study examines the performance of mutual funds investing in small cap companies in the period from 1990 until 2013. Therefore, funds investing in small companies in Germany are tested on their ability to deliver risk-adjusted abnormal returns. The returns are risk-adjusted according to Fama French (1996) three-factor model, Carhart four-factor model and the liquidity adjusted five-factor model of Pastor and Stambaugh (2003). A separate examination of the internet crisis 2000 until 2003 and the financial crisis period 2008 until 2013 is done, to assess the ability of fund managers in isolation to examine their results in situations when their skills are most needed. On average, I conclude that fund managers, investing in the small capitalization segment in Germany, are not able to outperform the market even before fees.

The main objective of this special issue is to divulge the applicability of the Neutrosophic Theory and to explore the possibilities and advantages of neutrosophic tools, through both the presentation of thorough research and case studies in solving social problems in Latin America. The best presentations discussed at the III International Congress of Educational Research and University Innovation, turned into papers, show us the capacity for socialization of neutrosophic knowledge and its link with this science of validation and consolidation of scientific knowledge. This publication with authors from 11 countries that we place in the hands of the international scientific community, constitutes an example of how in Latin America the Neutrosophy is contributing to complex solutions based on the results of scientific research carried out by teachers and students committed to the social responsibility of continuing to progress for the benefit of humanity.

“Neutrosophic Sets and Systems” has been created for publications on advanced studies in neutrosophy, neutrosophic set, neutrosophic logic, neutrosophic probability, neutrosophic statistics that started in 1995 and their applications in any field, such as the neutrosophic structures developed in algebra, geometry, topology, etc.

Examines the question of why, despite their explosive growth rate, mutual funds have not outperformed the stock market.
