• Does Twitter happiness predict bullish markets? A study of the US stock markets

  Vighneswara Swamy, Munusamy Dharani, Fumiko Takeda

  IIMB Management Review 36 ( 4 ) 309 - 321 2024.12

  Research paper (scientific journal), Joint Work, Lead author, Last author, Corresponding author, Accepted,  ISSN  09703896

  　View Summary

  The evolving literature on using Twitter to capture investor sentiment suggests that stock market performance is linearly associated with Twitter's public mood. We investigate whether investor sentiment determined by the Twitter sentiment index (TSI) has a nonlinear predictive power for stock market behaviour. Using a dataset of seven US stock markets, we apply the cointegration techniques to show the relationship between Twitter sentiment and stock market behaviour. The results suggest a dynamic nonlinear cointegrating relationship. During the short run, Twitter happiness has a substantial effect on stock market indices, while in the long run, it has a moderating effect. Twitter happiness has a dominant effect on the US stock market indices than unhappy Twitter. These results highlight Twitter's growing role in predicting the stock market behaviour and show that the TSI acts as a better predictor of investor sentiment.

• Empirical study on voting results and proxy advisor recommendations in Japan

  Hiroaki Miyachi, Fumiko Takeda

  Journal of International Financial Markets, Institutions and Money (Elsevier BV)  92   101973 - 101973 2024.04

  Research paper (scientific journal), Joint Work, Lead author, Last author, Corresponding author, Accepted,  ISSN  10424431

  　View Summary

  This study examines the relationship between proxy advisory firms’ recommendations and investors’ voting behavior in Japan, where corporate governance has been under transition. Based on 1,025 shareholder meeting proposals and recommendations by proxy advisory firms in Japan between March 2010 and March 2022, multivariate regression analyses reveal that the dissenting recommendations of the two main proxy advisory firms are negatively correlated with the approval rate of proposals, as well as the percentage of affirmative votes cast by institutional investors. Furthermore, the institutional investors’ behavior is more consistent with the recommendations of proxy advisory firms than that of other investors.

• Stock Price Reactions to Research and Development News on Pharmaceutical Companies in Japan

  T. Imai, F. Takeda

  2024 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM) (IEEE)     1119 - 1123 2024

  Research paper (scientific journal), Joint Work, Lead author, Last author, Corresponding author, Accepted,  ISSN  21573611

  　View Summary

  This study examines the effects of research and development (R&D) on the market value of Japanese pharmaceutical companies. Based on 1,345 news articles, our event study analysis of 74 Japanese pharmaceutical companies from 1 January 2010 to 31 December 2021 revealed three key findings. First, the stock prices of the aforementioned companies generally respond positively to the business news, and more specifically, R&D-related news. Second, the impact on the share price is more pronounced as the R&D progress to more advanced stages. Lastly, the stock price responses to R&D news tend to diminish as the size of pharmaceutical companies increases.

• Effects of shareholder proposals on the market value of Japanese firms

  Ryo Sato, Fumiko Takeda

  International Review of Economics and Finance (Elsevier)  86   320 - 333 2023.07

  Research paper (scientific journal), Joint Work, Corresponding author, Accepted,  ISSN  10590560

  　View Summary

  This study investigates the effect of shareholder proposals on the market value of Japanese firms in the second wave of activism from 2017 to 2021. While announcements of receiving a shareholder proposal positively affect stock prices of investee companies, rejection of a shareholder's proposal has a negative impact. Unlike the first wave of activism, proposals related to the election and dismissal of directors are no different from those of other proposals, which may become more important as shareholder proposals diversify. Similar to the first wave, market responses become larger when the large shareholders made the proposals.

• Effects of the COVID-19 pandemic on the market value of Japanese gaming companies

  Chi Feng, Fumiko Takeda

  Applied Economics (Taylor & Francis)  forthcoming ( 40 ) 4849 - 4860 2023.05

  Research paper (scientific journal), Joint Work, Corresponding author, Accepted,  ISSN  00036846

  　View Summary

  In this study, we examine the short-term stock price reactions of Japanese gaming companies to events related to the coronavirus disease 2019 (COVID-19) pandemic. Using the event study method, we first estimate stock price reactions to the outbreak of the pandemic and the declaration of a state of emergency. We then perform multivariate regressions to investigate the factors affecting market responses. Our results demonstrate that the stock prices of Japanese gaming companies reacted negatively to the outbreak of the COVID-19 pandemic, and the initial negative effects were greater for mobile gaming companies and for companies with small sizes or low Tobin’s Q. By contrast, the market has reacted positively to the declaration of the state of emergency, which perhaps drove more people to play games at home.
