This paper analyzes an alpha-seeking strategy with EVA. We use a long-short portfolio with high EVA and low EVA stocks. Using the normalized EVA, we construct a portfolio from the first to the fifth quintile and test the effectiveness of the strategy with the Carhart four-factor model. We find the following: (1) The portfolios with high EVA stocks outperform those with low ones; (2) EVA-based long-short portfolio generates 6.5% return per annum. This paper provides an empirical basis for launching a new equity fund with EVA in Korea. This strategy suggestion could also be extended to introduce new EVA investment strategies in other global markets.</p>","PeriodicalId":8570,"journal":{"name":"Asia-Pacific Journal of Financial Studies","volume":"53 6","pages":"732-753"},"PeriodicalIF":1.8,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Risk spillover measurements are calculated for both the short and long term by combining variational mode decomposition with the variance decomposition of vector autoregression. Our findings provide evidence of significant and time-varying spillovers among industries over time. The results on densities and assortativity coefficients indicate the presence of structural changes in the risk network during geopolitical crises. Furthermore, we find that the real linkage (input–output nexus) is an important determinant of long-term spillovers during periods of high GPR, and the information channel (market sentiment) is associated with risk contagion caused by GPR in both the short and long term. Overall, this paper offers valuable insights to prevent and mitigate the negative consequences triggered by geopolitical events on the stability of the economic system.</p>","PeriodicalId":8570,"journal":{"name":"Asia-Pacific Journal of Financial Studies","volume":"53 5","pages":"555-595"},"PeriodicalIF":1.8,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It identifies an inverted U-shaped pattern linking corporate financialization to innovation, with financing restrictions, agency costs, and business risk serving as some of the relationship's partial mediating factors. By categorizing financial assets into short-term monetary and long-term nonmonetary types, it reveals heterogeneous effects on innovative efficiency, suggesting that the impact is not solely crowding out or a pulling effect but varies based on asset type and proportion. Additionally, it argues for continual adjustment of proper corporate financialization levels based on firm-specific factors and changing external conditions. Notably, excessive financialization appears less prevalent among Chinese firms, with internal governance and external environmental enhancements recommended to optimize financialization for innovation.</p>","PeriodicalId":8570,"journal":{"name":"Asia-Pacific Journal of Financial Studies","volume":"53 4","pages":"467-503"},"PeriodicalIF":1.8,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141967379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
