The study covers the period from January 2021 to December 2024. The findings indicate that the market return is positively correlated by 100% with the returns of securities in the technology industry across all three categories: small-cap, mid-cap, and large-cap securities. In addition, it was found that the return of the Dow Jones index and exchange rates have a greater impact on the stock returns of large-cap technology securities than on those of small-cap and mid-cap securities.enReturnSecuritiesTechnologyArticle
