We collect data on unexpected exits from office to determine whether these exits affect stock market returns across countries between 1923 and 2015. Health problems precede almost all unexpected exits. Unexpected exits lead to about 1% abnormal return, due mainly to extreme positive jumps following exits of autocrats and non-college leaders. To identify citizens' awareness of a leader's health problems, we collect data on rumors about health issues emerging prior to the leader's exit. The start of rumors generates about 1% negative abnormal returns. The health of leaders matters.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80974364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Analyst Coverage and Managers’ Disclosure of Forward-Looking Information","authors":"James Warren","doi":"10.2139/ssrn.3702576","DOIUrl":"https://doi.org/10.2139/ssrn.3702576","url":null,"abstract":"Prior research documents that managers respond to an exogenous decrease in analyst coverage by increasing the quantity of a specific form of guidance (earnings forecasts), presumably to fill the information void left by a reduction in coverage. I extend this line of research by also considering the change in management forecast quality and an alternative form of guidance, managers’ forward-looking textual disclosures. First, although forecast quantity increases subsequent to loss of coverage and liquidity partially improves, I find forecast quality decreases (i.e., forecasts have larger signed and unsigned errors) and the decrease in quality attenuates the improvement in liquidity. These results suggest analysts not only play an informational role, but also a monitoring role with respect to managers’ forward-looking disclosures. These findings are more pronounced when (1) other monitors are not present to step in (i.e., dedicated intuitional owners and auditors) and (2) managers have incentives to engage in this disclosure behavior (i.e., engage in insider selling). Second, with respect to forward-looking textual disclosures, I find the quantity and net positivity of forward-looking textual disclosures in earnings announcements increase following loss of coverage. These results do not vary with other monitors’ presence, suggesting other parties do not monitor textual disclosures to the same extent as forecasting. However, the increase in net positivity of statements is concentrated in managers who engage in insider selling. Finally, I do not detect an improvement in liquidity from more textual disclosure or an association between net positivity and liquidity. Overall, my study provides a more nuanced view of analysts’ role in influencing firms’ disclosure of forward-looking information.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87918964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental evaluation on real data and different markets demonstrates the superior predicting performance as well as the relation of high volatility prediction to stocks with potential high risk and low return.

The market quality implications of the reduction in dark trading are mixed: while it tempers COVID-19-linked liquidity decline in the lit market, it exacerbates the loss of informational efficiency.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89080557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examine the influence of the COVID-19 pandemic on six different stock markets. Empirical analyses are conducted for four different time intervals to reveal the effect of the COVID-19 pandemic. The modified ICSS test shows that the pandemic has led to structural breaks in the volatility of stock indexes. While break dates intensify around February 19–21, 2020 in most of the markets, for the Chinese stock market, the break appears approximately three weeks earlier, on January 30, 2020. The DCC-MVGARCH and DCC-MVFIGARCH models illustrate the effect of the COVID-19 pandemic on dynamic conditional correlations. According to the changes in unconditional correlation coefficients, although the relationship of the Chinese and Turkish stock markets weakens across 2005 to 2019, it displays a 20% rise following the pandemic. Some other market pairs also show soaring correlation coefficients, although these increases are lower, at approximately 10%.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84183079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even and odd number higher order moments are strongly negatively correlated, creating periods where the return distribution is riskier because it is more left-skewed and fat tailed. The higher-moment risk increases in good times when variance is lower and prices are higher. This time variation is inconsistent with disaster-based models where disaster risk, and thus higher-moment risk, peaks in bad times. The variation in higher-moment risk also has important implications for investors as it causes the probability of a three-sigma loss on the market portfolio to vary from 0.7% to 1.9% percent over the sample, peaking in calm periods such as just before the onset of the financial crisis.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82412526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Risk of Financial Distress in Secondary Buyouts 二级收购中的财务困境风险

Even though general partners argue that SBOs are less attractive investment targets for buyouts and some empirical indication against an outperformance of SBOs exists, the share of SBOs continuously increases. However, SBOs might be a favourable target with regard to its investment risk. Using a unique dataset of 295 PBOs and their consecutive SBOs in the UK, we analyse the risk level of financial distress of the buyout rounds considering the Altman Z-Score. We find that SBOs reduce this risk of portfolio companies more than PBOs during the holding period. Therefore, SBOs, in general, cannot be seen as riskier investments. However, risk of financial distress is driven differently between PBOs and SBOs. The risk development in distressed companies is not different in PBOs and SBOs. However, SBOs perform better at risk management if the portfolio company is not distressed. This risk-adjusted view identifies SBOs as attractive investment targets. It also contributes to rectify investments in SBOs as rational and promising decisions.","PeriodicalId":11800,"journal":{"name":"ERN: Stock Market Risk (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84149961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
