    Net performance and alpha of EU equity mutual funds: a cross-country analysis
    (Rajesh K. Deshmukh : Raipur, 2026) Mešťan, Michal; Ščerba, Kamil; Ištok, Michal; Šafár, Leoš; Sopko, Jakub
    This paper examines whether equity mutual funds domiciled across European Union countries deliver systematically different outcomes for individual investors. Using a cross-country dataset, we analyze performance through quarterly fund returns and benchmark-adjusted alpha, focusing on full distributions rather than averages. Results show that raw returns differ across countries, with larger markets exhibiting more stable distributions and smaller or peripheral markets displaying higher volatility and downside risk. After adjusting for benchmarks, however, cross-country differences compress markedly. Alpha distributions cluster around zero, indicating that persistent outperformance is uncommon. A small group of Northern and core countries shows a slightly higher incidence of positive alpha, though effects remain modest. Overall, findings suggest that EU quity mutual funds can generate positive returns, but consistent market beating is rare and concentrated. Common market exposure and implementation costs dominate investor outcomes, implying that country domicile matters less for alpha than for raw return volatility across markets.

    Unpacking cybersecurity in financial research: a systematic mapping approach
    (Association of Economists and Managers of the Balkans - UdEkoM Balkan : Belgrade, 2025) Šafár, Leoš; Mešťan, Michal; Sopko, Jakub
    This study presents a comprehensive bibliometric and content analysis of cybersecurity research in financial institutions covering the period from 2000 to 2025. By applying the PRISMA (Pre- ferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology, we systematically identified and screened 2,005 peer-reviewed articles indexed in the Web of Science Core Collection. The review focuses on cybersecurity within the financial system, particularly in the banking and insur- ance sectors, and maps research trends, innovation gaps, and thematic evolutions in this domain. The- matic analysis on the basis of keyword co-occurrence identified three distinct clusters. The first cluster focuses on cybersecurity and artificial intelligence, including keywords such as cybersecurity, phishing, malware, and machine learning, highlighting AI-driven threat detection and digital defense mecha- nisms. The second cluster focuses on institutional risk management and information security, empha- sizing governance, authentication, and systemic controls within financial institutions. The third cluster involves emerging digital technologies, such as blockchain, cloud computing, and FinTech, underscor- ing the technological innovations that shape financial services and data protection frameworks. Despite growing research output and increasing attention to cyber risk from both academic and regulatory per- spectives, the field remains fragmented, with limited empirical evaluation of cybersecurity investment effectiveness. By combining PRISMA guidelines with bibliometric mapping, this study offers a struc- tured and interdisciplinary overview of cybersecurity research in financial institutions. It highlights key research frontiers and calls for deeper empirical inquiry, particularly on systemic financial risk, cross-sec- tor governance, and cybersecurity policy design.
