PurposeThis paper examines how “strategic” chief financial officers (CFOs) with an elite MBA (i.e. elite CFOs) influence (1) stock market reaction to CFO hiring announcements (ex ante measure) and (2) post-hiring firm performance (ex-post measure).Design/methodology/approachThis paper utilizes a comprehensive, proprietary database with information about the educational qualifications and prior professional experience of 1,340 CFOs hired during the period 1994–2014. For each CFO, the authors hand-collected data on the CFO's prior experience as well as CFO's educational profile. The authors also identified the date of CFO hiring from financial press articles. To evaluate performance, the authors consider two different, yet complementary performance measures: (1) the stock market reaction, a priori measure and (2) a traditional measure of performance, which is a post-facto metric related to firm performance.FindingsThe results show that hiring CFOs with scarce and strategic human capital elicits a positive market response and leads to significant improvement in firm performance. Further, firms with greater managerial discretion benefit more from hiring elite CFOs. The results hold after controlling for chief executive officer (CEO), CFO, top managment team (TMT), and board characteristics.Originality/valueThis study shows converging and mutually consistent results about what specific types of CFO human capital create firm value and, more importantly, show that such value-creation is only in the case of small firms and high growth firms. The study also advances the stream of literature that contrasts the relative benefits of specialist versus generalist qualifications.
目的本文研究了具有精英MBA学位的“战略”首席财务官(CFO)(即精英CFO)如何影响(1)股市对CFO招聘公告的反应(事前衡量)和(2)招聘后公司业绩(事后衡量),专有数据库,包含1994-2014年期间聘用的1340名首席财务官的学历和先前专业经验信息。对于每位首席财务官,作者手工收集了首席财务官之前的经验数据以及首席财务官的教育档案。作者还从财经媒体的文章中确定了首席财务官的聘用日期。为了评估绩效,作者考虑了两种不同但互补的绩效指标:(1)股市反应,这是一种先验指标;(2)传统的绩效指标,这是与企业绩效相关的事后指标。研究结果表明,雇佣具有稀缺战略人力资本的首席财务官会引发积极的市场反应,并显著改善公司业绩。此外,拥有更大管理自由裁量权的公司从雇佣精英首席财务官中受益更多。在控制了首席执行官(CEO)、首席财务官、最高管理团队(TMT)和董事会特征后,结果成立。独创性/价值这项研究显示了关于哪些特定类型的首席财务官人力资本创造企业价值的趋同和相互一致的结果,更重要的是,这表明这种价值创造只发生在小公司和高增长公司的情况下。这项研究还推进了对比专家资格与通才资格相对优势的文献流。

PurposeThe authors examine the influence of powerful political corporate appointments on the usage of firm bribery channels. Party Secretaries within Chinese state-owned enterprises (SOEs) may simultaneously hold top management positions, thereby endowing powerful firm-level decision rights on those appointees, hereafter referred to as powerful dual role Party Secretaries.Design/methodology/approachThis study employs panel data analysis with industry and year fixed effects. The authors use a sample of 1,143 Chinese SOEs listed on the Shanghai and Shenzhen Stock Exchanges from 2004 to 2015.FindingsThe authors find that powerful dual role Party Secretaries are associated with greater bribery channel usage. Following the ongoing anticorruption campaign, SOEs with the powerful appointments significantly reduce their usage of both transparent (entertainment and travel costs) and opaque bribery (abnormal management expenses) channels. However, in general, Chinese SOEs respond to the anticorruption shock by switching from the more transparent to the opaquer bribery channel.Originality/valueThe authors contribute to the ongoing debate of politicians on corporate boards by examining the relatively unexplored area of government appointed top management and their influence on bribery at the firm level.
目的研究有权势的政治公司任命对公司贿赂渠道使用的影响。中国国有企业的党委书记可以同时担任最高管理职位,从而赋予被任命者强大的企业级决策权,以下简称强大的双重角色党委书记。设计/方法/方法本研究采用了具有行业和年份固定效应的面板数据分析。作者使用了2004年至2015年在上海和深圳证券交易所上市的1143家中国国有企业的样本。在持续的反腐运动之后,拥有强大任命的国有企业显著减少了对透明(娱乐和差旅成本)和不透明贿赂(异常管理费用)渠道的使用。然而,总的来说,中国国有企业通过从更透明的贿赂渠道转向不透明的贿赂渠道来应对反腐败冲击。原创性/价值作者通过研究政府任命的最高管理层相对未被探索的领域及其对公司贿赂的影响,为公司董事会中政客们正在进行的辩论做出了贡献。

PurposeThe study examines the association between firm-level political risk and corporate innovation and also this study explores how financial constraint and growth level of a firm influence this association.Design/methodology/approach A sample of 14,140 firm-year observations of the US firms from 2003 to 2020 is used. Unlike prior studies, this study uses a firm-level measure of political risk recently developed by Hassan et al. (2019) and measure innovation by patent and patent citation data and a text-based measure. A regression technique is used for empirical testing.FindingsThis study finds that firm-level political risk is negatively associated with innovation and also document that firm-level political risk has a negative impact on innovation for financially constrained and high growth firms. The overall results are robust after addressing the issue of potential endogeneity using entropy balancing and two-stage least squares regression techniques. This study also documents qualitatively consistent results after using alternative measures of innovation as well as firm-level political uncertainty.Research limitations/implicationsThe findings of this study could help the managers to make better investment decision and improve economic efficiency through understanding the effect of firm-level political risk on innovation activities.Originality/valueThe study concentrates on firm-level political risk and innovation and presents new insights that political risk at the microlevel is an important determinant for investment in innovative activities.
目的本研究考察了企业层面的政治风险与企业创新之间的联系,并探讨了企业的财务约束和增长水平如何影响这种联系。设计/方法/方法使用了2003年至2020年美国公司14140个公司年度的观察样本。与之前的研究不同,本研究使用了Hassan等人最近开发的一种企业层面的政治风险衡量方法。(2019),并通过专利和专利引用数据以及基于文本的衡量标准来衡量创新。使用回归技术进行实证检验。研究结果本研究发现,企业层面的政治风险与创新呈负相关,也证明了企业层面的政策风险对财务受限和高增长企业的创新具有负面影响。在使用熵平衡和两阶段最小二乘回归技术解决潜在内生性问题后,总体结果是稳健的。这项研究还记录了在使用创新的替代措施以及公司层面的政治不确定性后,定性一致的结果。研究局限性/含义本研究的发现可以通过了解企业层面的政治风险对创新活动的影响,帮助管理者做出更好的投资决策,提高经济效率。独创性/价值这项研究专注于企业层面的政治风险和创新,并提出了新的见解,即微观层面的政治危机是创新活动投资的重要决定因素。

Whether corporate green bonds act as armour during crises? Evidence from a natural experiment 企业绿色债券是否能在危机中充当盔甲?来自自然实验的证据
IF 1.7 Q2 BUSINESS, FINANCE Pub Date : 2022-05-02 DOI: 10.1108/ijmf-10-2021-0501

PurposeThe present study examines the rationale behind the increased global presence of corporate green bonds as a green financing tool to facilitate sustainable practices and eco-friendly investing. The authors investigate the intriguing question of whether the companies that issue green bonds are valued more by investors or not, and further extend our analysis by exploring whether the green image of companies helps to minimize the value erosion during a crisis and enhance the resilience of the stocks?Design/methodology/approachTo examine the association between environmental commitments and firm value, the authors use the COVID-19 crisis as an exogenous shock and create a perfect natural setting to eliminate the endogeneity bias from our estimations. Moreover, the authors use propensity score matching to choose a one-to-one match of green bond firms with a larger pool of brown bond firms and eliminate the “size effect” arising out of the disproportionate sample size of green and brown bond firms.FindingsThe results of the study indicate that green bond firms are valued more by investors compared to brown bonds firms. Hence, green bond issuance acts as a strong signal of a firm's environmental commitment and it is well recognized by the investors. One of the possible reasons for a higher value of green bond firms may be due to their ability to arrest value erosion during environmental shocks. The authors could not find any difference in the resilience of green and brown bond firms.Originality/valueThe study contributes to the growing literature in the area of impact investing, specifically on exponentially growing innovative instrument green bond. Our study integrates two areas of research, i.e. corporate finance and impact investing by examining the impact of green bond issuance on firm value and stock market returns. The results would help environmentally sensitive investors to devise their investment portfolios more efficiently.
目的本研究探讨了企业绿色债券作为促进可持续实践和环保投资的绿色融资工具在全球范围内日益增加的理由。作者调查了一个有趣的问题,即发行绿色债券的公司是否更受投资者重视,并通过探索公司的绿色形象是否有助于最大限度地减少危机期间的价值侵蚀,增强股票的弹性,进一步扩展了我们的分析?设计/方法论/方法为了研究环境承诺与企业价值之间的关系,作者将新冠肺炎危机作为一种外部冲击,并创造一个完美的自然环境来消除我们估计中的内生性偏差。此外,作者使用倾向得分匹配来选择绿色债券公司与更大的棕色债券公司库的一对一匹配,并消除了由于绿色和棕色债券公司样本规模不成比例而产生的“规模效应”。研究结果表明,与棕色债券公司相比,绿色债券公司更受投资者重视。因此,绿色债券的发行是企业环保承诺的有力信号,受到投资者的认可。绿色债券公司价值较高的可能原因之一可能是它们有能力在环境冲击期间阻止价值侵蚀。作者没有发现绿色和棕色债券公司的弹性有任何差异。独创性/价值该研究有助于影响力投资领域不断增长的文献,特别是指数级增长的创新工具绿色债券。我们的研究通过考察绿色债券发行对公司价值和股票市场回报的影响,整合了两个研究领域,即公司融资和影响投资。研究结果将有助于对环境敏感的投资者更有效地设计投资组合。

Purpose

The study aims to identify the impact of board characteristics (BC) on a firm's environmental performance, and provides future research directions in the area of BC impact on environmental disclosures (ED) in case of India's environmentally sensitive and non-sensitive industries (SI and NSI).

Design/methodology/approach

The authors collect firm-level data from Prowess and Bloomberg, which cover 1,158 firm-year observations from National Stock Exchange of India (NSE) 500 listed companies from 2015 to 2020, and use a dynamic panel regression analysis to get deeper insights on the relationship of ED and BC.

Findings

The study found that lagged environment disclosure score is positively and significantly associated with current environmental disclosure scores. The presence of sustainability committee, board size and frequency of meetings has a positive and significant association with ED for sensitive as well as non-sensitive industry groups. Factors such as board Independence, board gender diversity and CEO duality have no significant impact on ED of both sensitive and non-sensitive industry groups.

Originality/value

Based on agency theory and stakeholder theory authors study for the first time in the context of India the effect of BC on ED using a large sample and covering an extensive period of six years. This study contributes by offering deep insights about the impact in case of “environmentally sensitive, non-sensitive and also all industries case”. The findings of this study are valuable for corporate managers and regulators who are interested in improving ED practices through a better-governed corporate mechanism.

目的本研究旨在确定董事会特征(BC)对公司环境绩效的影响,并就印度环境敏感和非敏感行业(SI 和 NSI)的董事会特征对环境信息披露(ED)的影响提供未来的研究方向。设计/方法/途径作者从 Prowess 和彭博社收集了公司层面的数据,这些数据涵盖了印度国家证券交易所(NSE)500 家上市公司从 2015 年到 2020 年的 1158 个公司年度观测值,并使用动态面板回归分析深入了解了环境披露与企业行为规范的关系。研究结果研究发现,滞后的环境披露得分与当前的环境披露得分显著正相关。在敏感和非敏感行业群体中,可持续发展委员会的存在、董事会规模和会议频率与环境披露有显著的正相关关系。董事会独立性、董事会性别多样性和首席执行官双重性等因素对敏感行业组和非敏感行业组的环境信息披露均无显著影响。 原创性/价值作者基于代理理论和利益相关者理论,首次在印度使用大量样本研究了可持续发展委员会对环境信息披露的影响,研究时间跨度长达六年。本研究有助于深入了解 "环境敏感型、非敏感型以及所有行业 "的影响。这项研究的结果对于有意通过更好的公司机制来改善教育实践的公司管理者和监管者来说非常有价值。

Does organizational form really matter to investment firms? 组织形式对投资公司真的重要吗?
IF 1.7 Q2 BUSINESS, FINANCE Pub Date : 2022-04-15 DOI: 10.1108/ijmf-12-2021-0608

PurposeThe purpose of this study is to investigate whether the organizational form of an investment management firm affects the performance of the mutual funds under its operation. More explicitly, this study aims to test whether funds managed by publicly listed firms achieve different risk-adjusted performance when compared with funds operated by privately held investment firms.Design/methodology/approachThis study uses Jensen's alpha to measure funds’ performance based on the Carhart’s (1997) benchmarks and market timing factors. The researchers test the relation between fund performance and organizational form using regressions. It alleviates the reverse causality and endogeneity using propensity score matching (PSM) methodology. The study investigates the difference in performance of funds managed by public firms on the post- vs pre- initial public offering (IPO) basis. Alternatively, this study tests the performance change post-public listing of the parent firm. It computes the difference for a matched sample of funds managed by private firms that were likely to go public but did not. The researchers match funds using PSM methodology.FindingsThis paper provides robust evidence that publicly traded management companies administer relatively under-performing mutual funds in comparison to those managed by privately held firms. To the best of the authors’ knowledge, this is the first paper that confirms that organizational decision is endogenous to performance. The study finds that after a privately held company goes public, the performance of their mutual funds and the performance of the matched group funds, whose companies remained private at the same time, tends to decline, compared with companies prior to the public offering. However, the decline in mutual fund performance is larger for the companies who chose to pursue their IPO.Originality/valueThe contribution of this study to the literature is twofold. First, while there is a wealth of literature on the impact of ownership structures on corporate performance, there are very few studies focused on mutual fund markets, despite the evidence that supports a generally mixed effect. This study confirms that the performance of mutual funds managed by publicly traded investments firms is lower than that of funds managed by privately held firms. Second, the organizational decision (private vs public) is not exogenous but depends on the actual funds’ performance.
目的本研究旨在探讨投资管理公司的组织形式是否会影响共同基金在其运作下的表现。更明确地说,本研究旨在测试上市公司管理的基金与私人投资公司运营的基金相比,是否实现了不同的风险调整绩效。设计/方法论/方法本研究基于Carhart(1997)基准和市场时机因素,使用Jensenα来衡量基金的业绩。研究人员使用回归检验了基金绩效与组织形式之间的关系。它使用倾向得分匹配(PSM)方法缓解了反向因果关系和内生性。该研究调查了上市公司管理的基金在首次公开募股后与首次公开募股前业绩的差异。或者,本研究测试了母公司公开上市后的业绩变化。它计算了由可能上市但没有上市的私人公司管理的基金的匹配样本的差异。研究人员使用PSM方法匹配资金。研究结果本文提供了有力的证据,表明与私营公司管理的基金相比,上市管理公司管理的共同基金表现相对较差。据作者所知,这是第一篇证实组织决策是绩效内生的论文。研究发现,与公开募股前的公司相比,私人控股公司上市后,其共同基金的业绩和匹配的集团基金的业绩往往会下降。然而,对于选择首次公开募股的公司来说,共同基金业绩的下降幅度更大。原始性/价值本研究对文献的贡献是双重的。首先,尽管有大量关于所有权结构对公司业绩影响的文献,但很少有研究关注共同基金市场,尽管有证据支持普遍的混合效应。这项研究证实,由上市投资公司管理的共同基金的业绩低于由私人控股公司管理的基金。其次,组织决策(私人与公共)不是外生的,而是取决于实际基金的绩效。

Second, the organizational decision (private vs public) is not exogenous but depends on the actual funds’ performance.","PeriodicalId":51698,"journal":{"name":"International Journal of Managerial Finance","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49447344","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}

PurposeThis study investigates the level of stock return synchronicity in African markets with the aim of establishing whether, contrary to conventional wisdom, stock return synchronicity can be low in countries with relatively weak information environments.Design/methodology/approachThe authors use a sample of five African countries (Botswana, Ghana, Kenya, Nigeria and South Africa) and a total of 616 firms over the period 2005–2015. This study's main measure of synchronicity is the R2 from a regression of stock returns on index returns. The authors also carry out regression analysis to investigate the main firm-level drivers of synchronicity.FindingsOn average, firms in African markets do not exhibit high levels of stock return synchronicity, providing support for the view that stock return synchronicity can be low in markets with relatively weak transparency. The authors, however, observe an increase in the level of synchronicity during the global financial crisis, notably for Ghana and Kenya. In the regression analysis, the main firm-level driver of synchronicity is firm size, while contrary to some previous studies, ownership structure has no impact. The authors also find evidence of the impact of changes in accounting regulation, notably the mandatory adoption of IFRS, on the level stock synchronicity.Originality/valueThis study contributes to the understanding of stock return synchronicity and how price discovery can vary between different information environments. The authors argue that stock returns in African countries may not always fit the stereotypical view that they are synchronous. The level of synchronicity among firms suggests that corporate events may carry some stock price implications.
本研究调查了非洲市场的股票收益同步性水平,目的是确定与传统观点相反,在信息环境相对薄弱的国家,股票收益同步性是否会较低。设计/方法/方法作者使用了五个非洲国家(博茨瓦纳、加纳、肯尼亚、尼日利亚和南非)和2005-2015年期间总共616家公司的样本。本研究的主要同步性度量是股票收益对指数收益回归的R2。本文还对同步性的主要驱动因素进行了回归分析。平均而言,非洲市场的公司并未表现出高水平的股票回报同步性,这为股票回报同步性在透明度相对较弱的市场中可能较低的观点提供了支持。然而,作者观察到,在全球金融危机期间,同步性水平有所提高,尤其是在加纳和肯尼亚。在回归分析中,企业层面同步性的主要驱动因素是企业规模,而与以往一些研究相反,股权结构对同步性没有影响。作者还发现了会计法规变化的影响的证据,特别是强制采用国际财务报告准则,对股票同步性的水平。原创性/价值本研究有助于理解股票收益同步性以及不同信息环境下价格发现的差异。这组作者认为,非洲国家的股票回报可能并不总是符合那种认为它们是同步的刻板印象。公司之间的同步性水平表明,公司事件可能会对股价产生一些影响。

Do stock markets value green operations? Evidence from India 股市重视绿色经营吗?来自印度的证据
IF 1.7 Q2 BUSINESS, FINANCE Pub Date : 2022-04-05 DOI: 10.1108/ijmf-06-2021-0305

PurposeThis study aims to examine the impact of green operation (measured using the energy intensity of its operations) on the value of corporate firms in stock markets. The authors also examine the channel of such an impact and its implication on a firm's financing choices.Design/methodology/approachThe authors conduct various univariate and multivariate regression analyses on a panel of all non-financial Indian firms listed on the National Stock Exchange from 2010 through 2018. The authors use the sensitivity of investments to the cash flows model to test the financial constraints hypothesis.FindingsThe authors’ analysis shows a positive relationship between energy efficiency (firms that consume a lesser amount of energy per unit of sale) and the value of firms in the stock market. The authors empirically attribute this greater valuation to the lesser volatility of stock returns, measured by the standard deviation of daily stock returns. Finally, the authors observe that investments in energy-efficient firms are less sensitive to their internal cash flows.Practical implicationsThe results suggest that less green firms face greater constraints in accessing finance from external sources and, therefore, depend more on internal than external capital to finance their investments. Hence, managers of such firms can ease their financing pressures by making their operations greener.Originality/valueIn this study, the authors examine the implications of green operations on the financing choices of firms. This aspect of going green is important because managers will have enough incentives to invest in green technologies as that would increase their access to external finance and, hence, decrease their financial constraints.
本研究旨在检验绿色经营(使用其运营的能源强度来衡量)对股票市场公司价值的影响。作者还研究了这种影响的渠道及其对企业融资选择的影响。设计/方法/方法作者对2010年至2018年在国家证券交易所上市的所有非金融印度公司进行了各种单变量和多元回归分析。作者利用投资对现金流模型的敏感性来检验财务约束假设。作者的分析表明,能源效率(每单位销售消耗较少能源的公司)与股票市场公司价值之间存在正相关关系。根据经验,作者将这种较高的估值归因于股票回报的波动性较小(以每日股票回报的标准差衡量)。最后,作者观察到,对节能企业的投资对其内部现金流不太敏感。结果表明,绿色程度较低的企业在获得外部融资方面面临更大的限制,因此,它们更多地依赖内部资本而不是外部资本来为其投资融资。因此,这些公司的管理者可以通过使他们的运营更环保来缓解他们的融资压力。原创性/价值在本研究中,作者考察了绿色运营对企业融资选择的影响。走向绿色的这一方面很重要,因为管理人员将有足够的动机投资绿色技术,因为这将增加他们获得外部资金的机会,从而减少他们的财政限制。

PurposeThe purpose of this paper is to investigate the relationship between investors' divergence of opinions and the asset prices of foreign stocks and also examine the effect of home market country-level factors on the influence of divergency of opinions on stock price.Design/methodology/approachThe authors employ panel data estimation with fixed effects to examine the host market response in divergent opinions to the earnings announcements. The paper uses the American Depositary Receipts (ADRs) of 42 countries from 1985 to 2011.FindingsThe authors find a negative relationship between differences of opinions and excess quarterly earnings announcement returns, and investors do process information asymmetrically based on good and bad earnings shocks. In addition, the authors find the negative relationship between divergent opinions and excess earnings announcement returns in ADRs is more pronounced in countries with short-sales restrictions, while other home-market country-level factors – the enforcement of insider trading law, legal origin, investor protection and rating on accounting standard – do not influence the relationship between investors' divergency of opinion and stock returns.Originality/valueThis paper is among the first to bring asymmetric effects on convergence in Miller framework and enhance the understanding of price convergence documented in Miller (1977). In addition, this study incorporates home-market country-level factors in explaining the relationship between investors' divergency of opinions and stock returns.
目的研究投资者意见分歧与国外股票资产价格之间的关系,并考察国内市场国家层面因素对意见分歧对股票价格的影响。设计/方法/方法作者采用具有固定效应的面板数据估计来检验东道国市场对不同意见的收益公告的反应。本文使用了42个国家从1985年到2011年的美国存托凭证(adr)。研究结果:作者发现,意见分歧与超额季度收益公告回报率之间存在负相关关系,投资者确实根据好与坏的收益冲击不对称地处理信息。此外,作者发现,在有卖空限制的国家,意见分歧与adr盈余公告超额收益之间的负相关关系更为明显,而其他国内市场层面的因素——内幕交易法的执行、法律来源、投资者保护和会计准则评级——并不影响投资者意见分歧与股票收益之间的关系。原创性/价值本文是第一批在米勒框架中引入不对称效应的研究之一,并加强了对米勒(1977)中记录的价格收敛的理解。此外,本研究纳入国内市场国家层面的因素来解释投资者意见分歧与股票收益之间的关系。

Purpose In this paper, the authors examine options trading in firms that soon become rumored takeover targets. This study also examines whether measures of informed trading can predict target returns (upon rumor announcement and over the post-rumor period) and/or predict which rumors lead to bids. The authors further assess whether the informed trading they observe is more prevalent in the options market or the equity market.Design/methodology/approach This study calculates abnormal options volume using a market-model approach that accounts for different attributes of options trading. The authors construct a control sample and compare equity options trading of firms in their sample with that of the control sample. In addition, the authors fit a series of regressions to examine whether pre-rumor abnormal options trading can predict rumor accuracy in a multivariate setting.Findings The authors find that the volume of options traded is abnormally high over the pre-rumor period while the direction of option trades (abnormal call volume minus abnormal put volume) prior to takeover rumors predicts forthcoming takeover announcements, rumor date target firm returns and post-rumor target firm returns. The results are robust when controlling for publicly available information, when using a control sample, and when using alternative measures of informed trading.Originality/value This study is the first to provide evidence of informed options trading prior to a broad sample of takeover rumors. In addition, this study contributes to the literature on takeover predictability and profitability by showing that various pre-rumor measures of informed options trading significantly predict bid announcements. The authors also contributes to the literature on price discovery by providing evidence that informed investors are more likely to trade in the options market than in the equity market during the pre-event period.
在本文中,作者研究了即将成为传言收购目标的公司的期权交易。本研究还考察了知情交易的措施是否可以预测目标回报(谣言宣布后和谣言后时期)和/或预测哪些谣言导致出价。作者进一步评估了他们观察到的知情交易在期权市场还是股票市场更为普遍。设计/方法/方法本研究采用考虑期权交易不同属性的市场模型方法计算异常期权成交量。本文构造了一个控制样本,并将样本内企业的股票期权交易与控制样本进行了比较。此外,作者拟合了一系列回归来检验在多变量环境下,谣言前异常期权交易是否可以预测谣言的准确性。研究发现,并购谣言前的期权交易量异常高,而收购谣言前的期权交易方向(异常看涨量减去异常看跌量)预测即将发布的收购公告、谣言日期目标公司收益和谣言后的目标公司收益。当控制公开可用的信息时,当使用控制样本时,当使用知情交易的替代措施时,结果是稳健的。原创性/价值本研究首次提供了在收购传闻广泛样本之前知情期权交易的证据。此外,本研究通过显示各种知情期权交易的谣言前度量显著预测出价公告,对收购可预测性和盈利能力的文献做出了贡献。作者还通过提供证据,证明知情的投资者在事件发生前更有可能在期权市场交易,而不是在股票市场交易,从而为价格发现的文献做出了贡献。
