Government responses to COVID-19 and market reactions to dividend announcements in ASEAN-5 countries Rizky Yudaruddin, Dadang Lesmana, Rozaimah Zainudin Asian Journal of Accounting Research, 2026 Purpose This study aimed to thoroughly examine the impact of government responses to the COVID-19 pandemic on market reactions to company dividend announcements in the Association of Southeast Asian Nations (ASEAN) countries. It also explored how these government responses influenced market reactions based on country-specific factors, dividend types and company characteristics. Design/methodology/approach In order to achieve the stated objectives, the event study method was adopted for this investigation using 5,648 dividend announcements made by various companies listed in 5 ASEAN countries from 2020 to 2022 to assess market reactions. Additionally, regression analysis with robust standard errors was conducted to examine the impact of government responses to COVID-19 on these market reactions. Findings The results showed that government responses to COVID-19 negatively affected market reactions to dividend announcements across the five explored ASEAN countries, with the strongest impact in Thailand and Indonesia. Investors in these countries were observed to be more concerned about the pandemic and strict policies such as lockdowns. This is particularly evident in dividend decreases and no-change announcements, as investors viewed stringent measures as signs of economic uncertainty, thereby reducing confidence in company stability. Accordingly, firm-level analysis showed that large, highly profitable and low-leverage companies experience stronger negative reactions, emphasizing the varying sensitivity of companies to government interventions. Originality/value The current study is the first to provide novel insights into government responses with the aim of determining the effectiveness of dividend announcements to market reactions during COVID-19 among companies in ASEAN countries.
Global material sector reactions to Trump's tariff postponement: multi-country evidence from an event study Ellen D. Oktanti Irianto, Rohana Nur Aini, Muhammad Ramadhani Kesuma, Dadang Lesmana, Rizky Yudaruddin Journal of Economics and Development, 2026 Purpose This study aims to investigate the market reactions of material firms to Trump's tariff postponement announcement on April 9, 2025, emphasizing variations across market types, industries, firm size, growth and tariff levels. Design/methodology/approach Applying an event study methodology, the research measures market reactions using Cumulative Abnormal Returns (CAR) for a sample of 1,174 firms from 47 countries. The analysis is conducted across market types, industries and firm characteristics, with cross-sectional regressions employed to assess the influence of tariff exposure on market behavior. Findings The findings reveal heterogeneous market reactions to the US tariff postponement announcement, with negative abnormal returns before the event turning significantly positive afterward across markets, industries and firm characteristics. The strongest post-event gains are concentrated in developed markets and highly trade-exposed industries such as Metals and Mining, Chemicals and Containers and Packaging, as well as among small-cap and high-growth firms. Cross-sectional results show that higher tariff exposure amplifies pre-event losses but leads to stronger positive cumulative abnormal returns after the announcement, reflecting investor optimism toward policy relief. Originality/value This study is the first to examine tariff postponements, rather than direct tariff impositions, across all US trade partners, offering new insights into how reduced policy uncertainty shapes global market sentiment. It also introduces the Material sector as a novel context, demonstrating how tariff shocks and their deferrals reverberate through industries that are central to global supply chains yet previously overlooked in the literature.
Asymmetric dynamics between global uncertainty and cryptocurrencies: evidence from quantile-on-quantile analysis Necati Altemur, İbrahim Halil Ekşi, Rizky Yudaruddin Journal of Modelling in Management, 2026 Purpose This study aims to provide a comprehensive examination of the nonlinear and asymmetric relationships between global uncertainty indicators, namely, gold (GOLD), the US Dollar Index (DXY) and the Volatility Index (VIX), and major cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), Cardano (ADA) and Binance Coin (BNB). It particularly focuses on how these dynamics evolve across different market conditions and the extent to which certain cryptocurrencies function as alternative safe-haven assets. Design/methodology/approach The analysis uses weekly data from January 2018 to June 2025, covering five major cryptocurrencies (BTC, ETH, XRP, ADA and BNB). To capture the dynamic and nonlinear relationships between global uncertainty indicators and cryptocurrency markets, the Quantile-on-Quantile Regression (QQR) approach is applied. Furthermore, the Quantile-on-Quantile Kernel-Based Regularized Least Squares (QQKRLS) technique is used as a robustness check to validate the findings. Findings The results demonstrate that the relationship between global uncertainty indicators and cryptocurrencies is neither linear, stationary nor unidirectional. Instead, it exhibits complex and asymmetric interactions that vary across quantiles and market conditions. Significant and predominantly inverse relationships are identified between the DXY, the VIX and cryptocurrencies, particularly at lower (0.05–0.30) and higher (0.70+) quantile levels. These findings suggest that investor behavior is influenced not only by economic fundamentals but also by uncertainty, market dynamics and risk perceptions. Originality/value This study is the first to apply QQR and QQKRLS methods to analyze the nonlinear and asymmetric linkages between global uncertainty indicators and major cryptocurrencies. It provides novel evidence on how these relationships shift across market conditions, offering fresh insights into the potential safe-haven role of cryptocurrencies.
BANK DIVERSIFICATION STRATEGY AND STOCK PRICE VOLATILITY DURING COVID-19 IN AN EMERGING COUNTRY Felisitas Defung, Ardi Paminto, Djoko Setyadi, Rizky Yudaruddin Corporate and Business Strategy Review, 2026 This study examines the impact of the COVID-19 pandemic on stock price volatility in the Indonesian banking sector and evaluates the moderating role of income diversification. The analysis covers 27 listed commercial banks during the 2017–2023 period across three phases: pre-pandemic, pandemic, and post-pandemic. Grounded in the efficient market hypothesis (EMH) and portfolio diversification theory, which suggest that markets rapidly reflect new information and that diversification can reduce risk, the study employs a fixed-effects regression model to assess volatility dynamics (Fama, 1970; Markowitz, 1952). The findings show that stock price volatility significantly increased during the pandemic, reflecting heightened market uncertainty, and gradually normalized in the post-pandemic phase. While income diversification does not significantly influence volatility in normal periods, it proves to be an effective risk-mitigation strategy during crisis periods. Banks with higher levels of diversification experienced lower volatility amid the pandemic, highlighting the stabilizing role of diversified income sources in times of market distress. These findings underscore the importance of strategic income diversification for enhancing resilience in the banking sector, contributing empirical evidence on how diversification interacts with systemic shocks, and offering practical implications for risk management and regulatory strategies in emerging financial markets.
Islamic Spiritual Care and consumer loyalty in Islamic hospitals: the roles of trust and satisfaction Muhammad Sadik Sahil, Syarifah Hudayah, Herning Indriastuti, Saida Zainurossalamia, Rizky Yudaruddin Innovative Marketing, 2026 Type of the article: Research ArticleAbstractSpiritual care has gained increasing relevance as an essential component of holistic healthcare, particularly within Islamic hospitals where religious values guide patient expectations and service experiences. This study aims to examine the influence of consumer trust, satisfaction, and service quality on the implementation of Integrated Islamic Spiritual Care (IISC), as well as to assess the mediating role of IISC in shaping consumer loyalty. A quantitative approach was employed, and data were collected through online and offline surveys, resulting in 265 valid patient responses from several Islamic hospitals in Indonesia. Structural Equation Modeling using the Partial Least Squares method was applied to evaluate the proposed relationships. The findings indicate that consumer trust (β = 0.330, p < 0.05), consumer satisfaction (β = 0.255, p < 0.05), and service quality (β = 0.366, p < 0.05) significantly contribute to the implementation of IISC. In turn, IISC exerts a substantial positive effect on consumer loyalty (β = 0.595, p = 0.000). The analysis of direct effects further reveals that only service quality has a significant impact on consumer loyalty (β = 0.703, p = 0.000), while the effects of trust and satisfaction are positive but not statistically significant (p > 0.05). Mediation testing confirms that IISC significantly mediates the effects of trust, satisfaction, and service quality on loyalty. These results demonstrate the strategic importance of spiritually integrated services in enhancing patient loyalty within Islamic hospital management.
Environmental awareness and digital financial literacy in improving the financial performance of medium enterprises in Indonesia: The roles of decision making and government support Siti Rohmah, Djoko Setyadi, Irwansyah Irwansyah, Ardi Paminto, Rizky Yudaruddin Investment Management and Financial Innovations, 2026 Type of the article: Research ArticleAbstractThis study examines how medium-sized enterprises improve financial performance through environmental awareness and digital financial literacy, with accounting information-based decision making as a mediating mechanism. The study focuses on medium-sized enterprises operating in East Kalimantan, particularly in the cities of Samarinda, Balikpapan, and Bontang, Indonesia, as this region represents a rapidly developing economic area with increasing environmental and digitalization challenges. Data were collected from 244 business owners and managers using stratified random sampling from June 2025 to September 2025. Partial Least Squares Structural Equation Modeling (PLS-SEM) is employed for analysis. The empirical results reveal that digital financial literacy has a stronger influence on financial performance than environmental awareness, emphasizing the dominant role of digital capability in driving firm outcomes. Furthermore, accounting information-based decision making significantly mediates these relationships, confirming its role as a crucial mechanism through which internal capabilities are translated into improved financial outcomes. The model also demonstrates strong explanatory and predictive power, indicating that the proposed framework effectively captures the key determinants of financial performance. The findings show that environmental awareness and digital financial literacy significantly enhance financial performance both directly and indirectly through accounting information-based decision making. The mediating role of decision making emerges as a key mechanism linking internal capabilities to firm performance, while government support does not significantly moderate these relationships. These results highlight the importance of internal behavioral and cognitive capabilities in strengthening the financial performance of medium-sized enterprises.
Market reaction to dividend announcements during COVID-19 pandemic in ASEAN countries Rizky Yudaruddin, Dadang Lesmana Asia Pacific Journal of Business Administration, 2025 PurposeThis study aims to investigate the market reaction to dividend announcements in five ASEAN countries during the COVID-19 pandemic. We focus on sectors that are less vulnerable during the COVID-19 pandemic, such as communication services, consumer staples, healthcare and information technology.Design/methodology/approachA sample of 5,648 dividend announcements from listed companies is utilized for this study, employing the event study method. The market reaction is measured using cumulative abnormal return (CAR), and cross-section regression is employed to examine the determinants of market reaction.FindingsThe findings reveal a significant positive reaction in the communication services, consumer staples, healthcare and information technology sectors following the announcement of an increase or decrease in dividends. These results imply that dividend increase announcements serve as a positive signal for investors amidst the COVID-19 pandemic. However, the market does not respond significantly to announcements of decreased and constant dividends during the pandemic as they are perceived as unfavorable signals. This paper also highlights the role of dividends as a communication tool through which companies express optimism in facing the challenges posed by the COVID-19 pandemic to their investors.Practical implicationsThis study highlights the role of dividends as a communication tool through which companies express optimism in facing the challenges posed by the COVID-19 pandemic to their investors.Originality/valueThis study offers a novel cross-country analysis of the market reaction to dividend announcements in the ASEAN region, considering both the pandemic and post-pandemic periods and focusing on sectors less impacted by COVID-19. Unlike previous studies that are limited to single-country or sector-specific analyses, our research uniquely addresses the broader ASEAN context and includes insights into the “new normal” period.
Disruptions in global trade routes: market reactions to the US–Houthi conflict in the consumer cyclical sector Rizky Yudaruddin, Dadang Lesmana, Yanzil Azizil Yudaruddin, Norliza Che Yahya, Ayesha Anwar International Journal of Development Issues, 2025 Purpose This study aims to investigate the market reaction in the cyclical consumer sector to the US–Houthi conflict. Furthermore, the authors explore the impact of this conflict on market reactions by market and region. Design/methodology/approach Using an event study methodology, this paper analyze a sample of 1,973 companies. This paper used multiple event windows, including a 15-day period before the invasion announcement as the preinvasion event and a 15-day period after the invasion announcement as the postinvasion event. Findings The authors find that pre the event of war, the market tended to show a positive reaction, but toward the event day until post event, the market in the consumer cyclical sector actually reacted significantly negatively to the conflict, especially in developed and developing markets. The Asia and Pacific market is the market that feels the most negative impact from the US–Houthi conflict compared to other markets. Furthermore, in terms of industry types in the consumer staples sector, Food and Tobacco and Personal and Household Products and Services felt the negative impact, although the majority of all industries reacted significantly negatively. Originality/value This study focuses on the US–Houthi conflict, an event that has not been extensively studied in the context of market reactions. Unlike previous research, this study specifically examines the impact of the conflict on the consumer cyclical sector, emphasizing the significance of trade route disruptions, particularly the Suez Canal, on global markets. By providing insights into how such geopolitical events affect different regions and industries, this study offers valuable guidance for policymakers and managers in mitigating the adverse effects of geopolitical risks on market stability.
