This study investigates asynchronous information transmission between stock returns and abnormal posting volume on the online stock message boards in China. Based on a robust GARCH model, the study finds that there are significant two-way volatility spillover effects: a positive volatility spillover effect from stock returns to abnormal message posting volume, and a negative volatility spillover effect from abnormal message posting volume to stock returns. The information exchange and communication on stock message boards have a certain role in stabilizing financial markets and improving investor's decision making on financial markets.

Abstract. Background: Little is known about presenting problems of primary posters (i.e., posters opening the thread) and their responders in nonprofessional against-suicide and pro-suicide message boards. Aims: We aimed to compare problems described in suicide message boards between different types of users (primary posters and respondents) and between against-suicide, neutral, and pro-suicide message boards. Method: In all, 1,182 archival threads with 20,499 individual postings from seven nonprofessional suicide message boards supporting an against-suicide, neutral, or pro-suicide attitude were randomly selected. Problems mentioned by primary posters and their respondents were coded with content analysis. Differences between pro-suicide, neutral, and against suicide boards, as well as correlations between primary posters and respondents, were calculated. Results: Interpersonal problems were most frequently mentioned by primary posters in against-suicide threads (40.9%) and less frequently in pro-suicide threads (11.8%; p < .001). In pro-suicide boards, the most frequent stressors were suicide method-related (e.g., how to identify a safe method: 26.2% vs. 2.5% in against-suicide boards, p < .001). Primary posters resembled respondents in terms of presenting problems in pro-suicide boards, but not in against-suicide boards. Limitations: Only self-reported problems were assessed. Conclusion: The results confirm a stronger focus on death than on life among users in pro-suicide message boards, and posters with similar problems meet in pro-suicide boards. The posters appear to clearly emphasize social strains over psychiatric problems compared with some professional settings.

Human rights and fundamental freedoms such as economic, political, and press freedoms vary widely from country to country. It creates opportunity and risk in investment decisions. Thus, this study is carried out to examine if the explanatory power of the model for capital asset pricing could be improved when these human rights movement indices are included in the model. The sample for this study comprises of 495 stocks listed in Bursa Malaysia, covering the sampling period from 2003 to 2013. The model applied in this study employed the pooled ordinary least square regression estimation. In addition, the robustness of the model is tested by using firm size as a controlled variable. The findings show that market beta as well as the economic and press freedom indices could explain the cross-sectional stock returns of the Malaysian stock market. By controlling the firm size, it adds marginally to the explanation of the extended CAP model which incorporated economic, political, and press freedom indices.
