We study the effect of head of states' health on markets. 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.
我们研究国家元首的健康状况对市场的影响。我们收集了1923年至2015年间意外离职的数据,以确定这些离职是否会影响各国的股市回报。几乎所有意外退出之前都会出现健康问题。意外退出导致的异常回报约为1%,这主要是由于独裁者和非大学领导退出后的极端正跳跃。为了确定公民对领导人健康问题的意识,我们收集了有关领导人离职前出现健康问题的谣言的数据。谣言开始产生约1%的负异常收益。领导者的健康很重要。

Analyst Coverage and Managers’ Disclosure of Forward-Looking Information 分析师覆盖范围和经理人披露前瞻性信息
Pub Date : 2020-09-30 DOI: 10.2139/ssrn.3702576
James Warren
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.
先前的研究表明,管理者通过增加一种特定形式的指导(收益预测)的数量来应对分析师覆盖率的外生减少,可能是为了填补覆盖率减少留下的信息空白。我通过考虑管理预测质量的变化和另一种指导形式——管理者的前瞻性文本披露,扩展了这条研究线。首先,尽管预测数量会随着覆盖率的减少而增加,流动性也会部分改善,但我发现预测质量会下降(即,预测有较大的签名和未签名错误),而且质量的下降会削弱流动性的改善。这些结果表明,在管理者的前瞻性披露方面,分析师不仅发挥信息作用,而且发挥监督作用。当(1)没有其他监督者介入(即,专门的直觉所有者和审计师)和(2)管理人员有动机参与这种披露行为(即,参与内幕销售)时,这些发现更加明显。其次,关于前瞻性文本披露,我发现收益公告中前瞻性文本披露的数量和净积极性随着覆盖率的减少而增加。这些结果不随其他监督者的存在而变化,这表明其他各方对文本披露的监督程度不如预测。然而,报表净收益的增加主要集中在从事内幕销售的经理人身上。最后,我没有从更多的文本披露或净正性与流动性之间的关联中发现流动性的改善。总体而言,我的研究对分析师在影响公司披露前瞻性信息方面的作用提供了更细致入微的看法。

We investigate the performance of more than 21,000 technical trading rules on 12 categorical and country-specific markets over the 2004-2015 study period. For this purpose, we apply a discrete false discovery rate approach in more than 240,000 hypotheses and examine the profitability, persistence and robustness of technical analysis. In terms of our results, technical analysis has short-term value. A novel cross-validation exercise highlights the importance of frequent rebalancing and supports our findings. Financial stress seems to have a strong negative effect in technical analysis profitability for US markets and a strong positive effect for emerging and other advanced markets.
我们调查了2004-2015年研究期间12个分类和特定国家市场上超过21,000个技术交易规则的表现。为此,我们在超过240,000个假设中应用离散错误发现率方法,并检查技术分析的盈利能力,持久性和稳健性。就我们的结果而言,技术分析具有短期价值。一项新的交叉验证练习强调了频繁再平衡的重要性,并支持了我们的发现。金融压力似乎对美国市场的技术分析盈利能力有强烈的负面影响,对新兴市场和其他发达市场有强烈的积极影响。

Comparing Theories of One-Shot Play Out of Treatment 单次打法治疗理论比较
Pub Date : 2020-06-03 DOI: 10.2139/ssrn.3441675
Philipp Külpmann, Christoph Kuzmics
We collect data of one-shot play for a representative selection of two by two games with unique and completely mixed strategy predictions, to compare the predictive power of theories of one-shot play ``out of treatment:'' competing theories are calibrated with pre-existing data using different games and subjects. We find that all theories, except Nash equilibrium, have predictive power; no theory is uniformly best; and taking into account risk aversion significantly improves predictive power. Finally, Nash equilibrium with risk aversion is among the best predictors of play, except for one player position in games of a matching pennies variety.
我们收集了具有独特和完全混合策略预测的2 × 2游戏的代表性选择的一次性游戏数据,以比较一次性游戏理论的预测能力:“竞争理论使用不同游戏和主题的预先存在数据进行校准。”我们发现,除了纳什均衡,所有理论都有预测能力;没有理论总是最好的;将风险厌恶考虑在内,可以显著提高预测能力。最后,带有风险厌恶的纳什均衡是最好的预测因素之一,除了在匹配硬币的游戏中有一个玩家的位置。

Incorporating environmental, social, and governance (ESG) considerations into systematic investments has drawn numerous attention recently. In this paper, we focus on the ESG events in financial news flow and exploring the predictive power of ESG related financial news on stock volatility. In particular, we develop a pipeline of ESG news extraction, news representations, and Bayesian inference of deep learning models. 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. It also shows the prospect of the proposed pipeline as a flexible predicting framework for various textual data and target variables.
最近,将环境、社会和治理(ESG)因素纳入系统性投资引起了许多关注。本文以财经新闻流中的ESG事件为研究对象,探讨ESG相关财经新闻对股票波动的预测能力。特别是,我们开发了ESG新闻提取、新闻表示和深度学习模型的贝叶斯推理管道。对真实数据和不同市场的实验评价表明,该方法具有较好的预测效果,同时也证明了高波动率预测与潜在高风险低收益股票的关系。它还显示了所提出的管道作为各种文本数据和目标变量的灵活预测框架的前景。

COVID-19: Venue Selection Effects and Implications for Market Quality 2019冠状病毒病:场地选择效应及其对市场质量的影响
Pub Date : 2020-04-27 DOI: 10.2139/ssrn.3586410
Gbenga Ibikunle, Khaladdin Rzayev
We investigate the effects of the COVID-19-induced shock in financial markets on aggregate venue selection/market share and market quality. We find that the shock is linked with an economically significant loss of market share by dark pools to lit exchanges. In line with theory, the loss appears driven by an increase in lit market volatility and a search for immediacy by traders active in stocks with dark trading access. 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.
我们研究了新冠肺炎引发的金融市场冲击对总场地选择/市场份额和市场质量的影响。我们发现,这种冲击与黑池向灯火交易所流失市场份额在经济上的重大损失有关。与理论相符的是,亏损似乎是由市场波动加剧,以及活跃于拥有暗交易渠道的股票的交易员寻求即时性造成的。暗盘交易减少对市场质量的影响喜忧参半:虽然它缓和了与covid -19相关的现货市场流动性下降,但它加剧了信息效率的丧失。

A New Form of Financial Contagion: COVID-19 and Stock Market Responses 新形式的金融传染:COVID-19和股市反应
Pub Date : 2020-04-20 DOI: 10.2139/ssrn.3584243

The COVID-19 pandemic has induced a different and more severe version of the contagion phenomenon. 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%.
COVID-19大流行引发了一种不同的、更严重的传染现象。在本研究中,我们考察了COVID-19大流行对六个不同股票市场的影响。通过四个不同的时间间隔进行实证分析,揭示新冠肺炎大流行的影响。修正后的ICSS检验表明,疫情导致股指波动出现结构性断裂。虽然大多数市场的休市日期在2020年2月19日至21日左右加剧,但对于中国股市来说,休市日期大约提前三周,即2020年1月30日。DCC-MVGARCH和DCC-MVFIGARCH模型说明了COVID-19大流行对动态条件相关性的影响。从无条件相关系数的变化来看,虽然2005年至2019年中国和土耳其股市的相关性减弱,但在疫情后却上升了20%。其他一些市场对也显示出飙升的相关系数,尽管这些增幅较低,约为10%。

The Unprecedented Stock Market Impact of Covid-19 Covid-19对股市的前所未有的影响

No previous infectious disease outbreak, including the Spanish Flu, has impacted the stock market as forcefully as the COVID-19 pandemic. In fact, previous pandemics left only mild traces on the U.S. stock market. We use text-based methods to develop these points with respect to large daily stock market moves back to 1900 and with respect to overall stock market volatility back to 1985. We also evaluate potential explanations for the unprecedented stock market reaction to the COVID-19 pandemic. The evidence we amass suggests that government restrictions on commercial activity and voluntary social distancing, operating with powerful effects in a service-oriented economy, are the main reasons the U.S. stock market reacted so much more forcefully to COVID-19 than to previous pandemics in 1918-19, 1957-58 and 1968.
此前,包括西班牙流感在内的任何传染病疫情都没有像新冠肺炎疫情那样对股市造成如此强烈的影响。事实上,之前的流行病对美国股市只留下了轻微的影响。我们使用基于文本的方法,根据1900年以来的每日股市大幅波动,以及1985年以来的整体股市波动,来开发这些点。我们还评估了股市对COVID-19大流行前所未有的反应的潜在解释。我们收集的证据表明,政府对商业活动和自愿保持社会距离的限制在服务型经济中发挥了强大的作用,这是美国股市对COVID-19的反应比1918- 191957 -58和1968年的前几次大流行强烈得多的主要原因。

Higher-Moment Risk Higher-Moment风险
Pub Date : 2020-02-18 DOI: 10.2139/ssrn.3069617
N. J. Gormsen, C. Jensen
We use a new method to estimate ex ante higher order moments of stock market returns from option prices. 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.
本文用一种新的方法从期权价格估计股票市场收益的事前高阶矩。偶数和奇数高阶矩是强烈负相关的,创造了回报分布风险更大的时期,因为它更左偏和肥尾。在方差较低、价格较高的好时机,高时刻风险增加。这种时间变化与基于灾害的模型不一致,在这些模型中,灾害风险以及更高时刻的风险在糟糕时期达到峰值。高时刻风险的变化对投资者也有重要的影响,因为它导致市场投资组合出现三西格玛损失的概率在样本中从0.7%到1.9%不等,在平静时期达到峰值,比如金融危机爆发之前。

Risk of Financial Distress in Secondary Buyouts 二级收购中的财务困境风险
Pub Date : 2019-12-23 DOI: 10.2139/ssrn.3508613
Tjark Eschenröder, Thomas Hartmann-Wendels
Secondary buyouts (SBOs) represent more than 50 percent of all buyouts in 2018. 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.
二级收购(sbo)占2018年所有收购的50%以上。尽管普通合伙人认为sbo是不那么有吸引力的收购投资目标,并且存在一些反对sbo表现优异的实证迹象,但sbo的份额仍在不断增加。然而,就其投资风险而言,sbo可能是一个有利的目标。利用英国295家pbo及其连续sbo的独特数据集,我们分析了考虑Altman Z-Score的收购轮次的财务困境风险水平。我们发现,在持股期间,sbo比pbo更能降低投资组合公司的这种风险。因此,一般来说,sbo不能被视为风险较高的投资。然而,财务困境风险在pbo和sbo之间的驱动是不同的。不良企业的风险发展在pbo和sbo中没有差异。然而,如果被投资公司没有陷入困境,sbo在风险管理方面的表现会更好。这种风险调整后的观点将sbo视为有吸引力的投资目标。它还有助于将对sbo的投资纠正为理性和有希望的决策。
