Abstract

This study aims to evaluate the performance of equity mutual funds (EMFs) traded on the Turkey Electronic Fund Trading Platform (TEFAS) using Data Envelopment Analysis and Malmquist Total Factor Productivity Index. Portfolio size and management fees were used as input variables, while net return rate was used as the output variable. When examining the efficiency of equity mutual funds in 2020, it was found that out of a total of 40 EMFs, the “Tacirler Portfolio Equity Fund” was efficient under the assumption of Constant Returns to Scale (CRS). For 2021, among 45 EMFs, “Inveo Portfolio G-20 Countries Foreign” and “İş Portfolio Foreign” were found to be efficient under the CRS assumption. In 2022, among 54 EMFs, “ICBC Turkey Portfolio” was identified as efficient under the CRS assumption. In 2023, based on an analysis of 66 EMFs, “Ak Portfolio New Technologies Foreign” and “Inveo Portfolio G-20 Countries Foreign” were efficient under the CRS assumption. In 2024, among 89 EMFs, “Pardus Portfolio First” was found to be efficient under the CRS assumption. The findings reveal that 2021–2022 was the only period during which total factor productivity increased. According to the analysis of total factor productivity change, the three investment funds exhibiting the highest efficiency improvements between 2020 and 2024 were, respectively, Ak Portfolio Equity (TRY) Fund, Inveo Portfolio First Equity Fund, and İş Portfolio Equity (TRY) Fund.

Özet

Bu çalışmada, Türkiye Elektronik Fon Alım Satım Platformu’nda (TEFAS) işlem gören hisse senedi yatırım fonlarının (HSF) performansının Veri Zarflama Analizi (VZA) ve Malmquist Toplam Faktör Verimlilik Endeksi yöntemleriyle değerlendirilmesi amaçlanmıştır. Analizde, girdi değişkenleri olarak portföy büyüklüğü ve yönetim ücreti; çıktı değişkeni olarak ise net getiri oranı kullanılmıştır. 2020 yılı hisse senedi yatırım fonları etkinliği incelendiğinde, toplam 40 HSF arasında yalnızca “Tacirler Portföy Hisse Senedi Fonu”nun, ölçeğe göre sabit getiri (Constant Returns to Scale – CRS) varsayımı altında etkin olduğu belirlenmiştir. 2021 yılı HSF etkinliği sonuçlarına göre ise, toplam 45 HSF içerisinden “Inveo Portföy G-20 Ülkeleri Yabancı Hisse Senedi Fonu” ile “İş Portföy Yabancı Hisse Senedi Fonu”nun CRS varsayımı altında etkinlik gösterdiği tespit edilmiştir. 2022 yılı HSF etkinliği incelendiğinde toplam 54 HSF içerisinden “ICBC Turkey Portföy”ün CRS varsayımı altında etkin olduğu görülmektedir. 2023 yılı HSF etkinliğine göre 66 HSF içerisinden “Ak Portföy Yeni Teknolojiler Yabancı” ve “Inveo Portföy G-20 Ülkeleri Yabancı”nın CRS varsayımı altında etkin olduğu görülmektedir. 2024 yılı HSF etkinliği incelendiğinde toplam 89 HSF içerisinden “Pardus Portföy Birinci”nin CRS varsayımı altında etkin olduğu görülmektedir. 2020-2024 dönemi incelendiğinde, toplam faktör verimliliğinde artış gösteren tek dönem 2021-2022 olarak belirlenmiştir. Toplam faktör verimliliği değişimi analizine göre, 2020-2024 sürecinde etkinlik değişiminin en yüksek olduğu üç yatırım fonu sırasıyla Ak Portföy Hisse Senedi (TL) Fonu, Inveo Portföy Birinci Hisse Senedi Fonu ve İş Portföy Hisse Senedi (TL) Fonu olarak tespit edilmiştir.
