Abstract :New technological products and methods not only have the potential to increase efficiency but also force business processes to change. Globalization has increased the speed of development and dissemination of current technologies, and their impact has deepened. Business processes and financial assets in the finance sector are significantly affected by these developments. Additionally, the significant increase in the value of technology company stocks in recent years has attracted the attention of investors and researchers. The aim of this study is to investigate whether there is a cointegration relationship among the indices formed by the values of technology company stocks in different markets. The indices selected for examination are the NASDAQ 100 Technology TR (NTTR) from the United States, the iShares STOXX Europe 600 Technology UCITS (SX8PEX) from the European Union markets, and the FTSE TechMARK All Share (FTTASX) from the United Kingdom. Time series have been created based on the monthly closing values of selected indices between December 2018 and February 2024. The unit root test results showed that all series have a degree of stationarity of 1 (I=1). The potential cointegration relationships between the series were investigated using the Johansen Cointegration method, and specification tests were conducted. As a result of the study, it was determined that there is no significant cointegration relationship among the selected technology index series.
