上市公司违规短线交易行为分析

违规短线交易扰乱市场秩序危害投资者权益,其存在增加市场的不稳定性。那么分析其认定方法和其存在的原由,以及高管辩解理由与惩罚力度变得十分重要。     

上市公司高管违规短线交易行为研究

本文从三个方面对我国上市公司高管(含董事、监事和高层管理者)的短线交易行为进行了研究:(1)上市公司高管的短线交易能获得超额收益吗?(2)不同职位的高管获得的收益具有差别吗?(3)高管为短线交易行为提出的辩解理由是真实的吗?基于上交所和深交所的数据,本文的经验研究发现:整体而言,上市公司高管的短线交易行为能获得超额收益;尤其是监事的短线交易行为更多、"择时"能力更强;未说明原因的短线交易行为(即默认故意实施的短线交易)与"对相关规定不了解"这两种具有主观意图的短线交易都能获得超额收益,而"误操作"导致的短线交易平均而言未能获得超额收益,这意味着高管提出的辩解理由整体而言是真实的。     

证券内幕交易的法律规制探究

为有效遏制证券内幕交易,完善我国的内幕交易法律规制体系,在事前预防方面,需增加信息披露的种类和方式,拓宽信息披露的渠道,规范上市公司收购时信息披露的规则;在事中监控方面,需明确证券监管机构的职权,构建联合监管体系,强化社会公众监督;在事后制裁方面,要明确民事诉讼主体的认定,确定举证责任,加大经济处罚的力度。     

禁止证券内部交易制度的若干法律问题

内幕交易(Inside Trading)．又称内部人交易或知情交易，是指掌握公开发行有价证券企业未公开的，可以影响证券价格的重要信息的人，直接或间接地利用该信息进行证券交易，以获取利益或减少损失的行为。内幕交易行为严重破坏证券市场的秩序，动摇投资者的信心，必须用法律加以规制。     

论对证券内幕交易法律规制

内幕交易就是内幕信息人员利用内幕信息从事证券交易的违法行为。证券市场内幕交易严重侵犯了投资者的平等知情权和财产权益,影响证券市场功能的发挥。对于内幕交易的法律规制是保障证券市场健康平稳运行的及经济发展的重要方面。本文试讨论了证券市场内幕交易的特点、危害及认定标准,结合各国的相关立法与我国的法律现状进行分析比较,并提出一些监管建议。     

英美两国对证券内幕交易的认定及法律规制

英美两国对证券内幕交易的认定美国是较早对证券内幕交易进行法律规制的国家。1934年美国的《证券交易法》首先以法律形式禁止包括内幕交易在内的各种证券欺诈行为,在1984年的《内幕交易制裁法》和1988年的《内幕交易与证券欺诈强制法》中又进一步采取了更严厉的措施。尽管成文     

内幕交易的法律规制研究

在证券交易活动中,内幕交易行为时有出现,而且在资本市场企业并购重组活跃环境下,内幕交易不断呈现出新的态势.该行为不仅损害广大投资者的正当利益,而且严重违背证券市场公开、公平、公正的原则,破坏了证券市场的正常交易秩序.故而,我们必须要认清内幕交易的现状,发现并立足于现有防范措施存在的缺陷,完善内幕交易的法律规制,以维护资本市场的健康发展.     

内幕交易新动向及其法律规制研究

在资本市场企业并购重组活跃环境下,内幕交易这一资本市场"痼疾"不断呈现出新动向,如行为加剧化、主体多元化等.内幕交易新动向的法律成因主要在于现行法律法规对内幕交易规制的缺陷,即内幕交易法律责任的不力、内幕信息认定标准的不足、内幕交易取证的不易以及上市公司内部控制信息披露机制的不健全.因此,应立足于这些缺陷,完善内幕交易的法律规制,以维护资本市场的健康发展.     

浅析排放权交易法律制度

当今社会,人们在发展经济的同时也来越注重探索与自然和谐相处之道。经济发展的负外部性是引发环境问题的重要原因,排放权交易运用灵活的市场手段,有效地较少了企业生产所产生的污染物的排放,提高了企业减排的积极性。排放权交易的良性发展与顺利进行需要法律制度的规范和保障,本文理清排放权交易法律制度现实发展的情况,并对排放权交易法律制度的基本理论进行初步的探索。     

上市公司内部人亲属股票交易行为研究

中国的《证券法》等法律法规禁止内部人短线交易,并设置了内部人禁止股票买卖的敏感期,但内部人亲属不受此限制。本文对深圳证券交易所2007年5月至2010年5月的内部人亲属股票交易数据分析发现:(1)上市公司的内部人亲属对内部人任职企业的股票交易次数已经远远多于内部人自身的交易次数;(2)内部人亲属的交易存在很多的短线交易行为与敏感期交易行为;(3)内部人亲属股票交易整体而言能够获得超额收益;(4)短线交易与敏感期交易有助于内部人亲属获得超额收益;(5)董事长或总经理的亲属获得的收益比其他内部人亲属更高。据此,本文认为证券交易监管机构需要关注内部人亲属股票交易行为,尤其警惕内部人亲属交易可能成为规避内部人交易管制的替代方式。     

Social networks and managerial rent-seeking: Evidence from executive trading profitability

This study examines whether board social networks are associated with executive trading profitability. Using a sample of US public firms with a history of executive trading from years 2000 to 2015, we find robust evidence that the profitability of executive trading is significantly lower in firms with higher levels of board social networks. The evidence is consistent with our view that board social networks effectively curb executives' private information advantage over outsiders, thus leading to a lower level of managerial rent-seeking. Our research has policy implications for regulators concerned about the role of corporate board in capital markets.     

浅析单位内幕交易违法的认定与处罚

近年,单位作为主体从事内幕交易的案例呈增加之势。本文结合行政执法与刑事司法实践,结合近年典型单位内幕交易案例,并借鉴海外监管查处经验,着重讨论了单位内幕交易认定的一些疑难法律问题,诸如是否将单位作为违法主体以及是否处罚、如何认定单位知悉与利用内幕信息、如何区分单位内幕交易行为与个人内幕交易行为等问题。     

Target insiders' preferences when trading before takeover announcements: Deal completion probability,premium and deal characteristics

We contribute to the M&A literature by characterizing the information available to target insiders during the pre-public takeover negotiations. We analyze insider trading in target firms in the US between 2005 and 2018. First, we show that signing confidentiality agreements is an important information threshold. Second, insiders have a good grasp of deal success. They increase their net purchases only in deals with higher completion probability. Third, insiders guess the final offer price well, but their trading strategies additionally reflect their knowledge of deal characteristics. They prefer bidder-initiated, cash, privately negotiated, and strategic deals. Insiders combine several sources of information.     

Do corporate insiders circumvent insider trading regulations? The case of stock repurchases

We use calculated values of standardized abnormal insider trading activity to investigate for patterns of unusual insider activity around fixed-price and Dutch auction repurchase announcements. Firms are classified according to whether the repurchase is signaling information about future cash flows, about the distribution of excess free cash flows, or about management's attempts to maintain control in the presence of a takeover. We find below normal levels of sales well before the event and above normal levels of sales after the event. This tendency is strongest for fixed-price offers and for firm's conveying information about future cash flows, and is absent for firms involved in takeovers. No evidence exists of abnormal levels of purchases before or after the event. We interpret the evidence as consistent with insiders successfully circumventing policies and regulations designed to prevent the exploitation of private information by timing the pattern of their security sales.     

Insider trading in rumored takeover targets

We examine insider trading surrounding takeover rumors in a sample of 1,642 publicly traded US firms. Using difference-in-differences regressions, we find that insider net purchases increase within the year prior to the first publication of a takeover rumor, particularly when rumor articles are either accurate (lead to a takeover announcement) or informative (provide substantial justification for the rumor's publication). Moreover, we find abnormal insider trading to be a significant predictor of takeover announcements occurring within the following year. Finally, passive net purchasing (i.e., selling less rather than buying more) is more pronounced among managing insiders than among non-managing insiders.     

我国证券市场内幕交易的法学实证分析——来自31起内幕交易成案的统计分析

内幕交易是证券法学界炙手可热、经久不衰的热门课题,关于内幕交易的各种概念、学说、理论被学术界翻炒得烂熟,解剖个案麻雀的精彩论著也不鲜见,但受制于案例、资料和相关数据的局限,少有学者从实证角度,系统性地研究我国内幕交易成案的总体特征。本文力图在传统证券法学研究途径之外,独辟蹊径,通过运用统计、数量分析等经济学科工具,对证券市场成立以来查处的全部31起内幕交易案件加以实证分析,以期得出我国内幕交易案件的发案特征与规律,为打击和防范内幕交易违法行为,修订内幕交易法制提供数据支持和实证参考。     

对金融衍生品市场内幕交易的一些新思考--澳大利亚现行的反内幕交易法及其带给我们的若干启示

本文着眼于澳大利亚在治理金融衍生品市场内幕交易中积累的丰富经验,针对一个崭新的前瞻性课题,即金融衍生品市场的内幕交易问题展开研究。作者认为,由于内幕交易与信息非对称性之间存在的内在冲突,实际上反内幕交易法规很难有效地阻止金融衍生品的内幕交易行为,过于复杂的反内幕交易法规会对市场产生一些负面影响,而放松内幕交易监管这一新思维将对市场的良性发展更为有益,应该让市场来决定内幕交易行为的“存亡”。但目前最为现实、温和的选择仍然是修改现行反内幕交易法,以维护市场的公平性和有效性。最后,笔者对如何缓解中国目前内幕交易猖獗的现状提出建议。     

Aggregate insider trading and market returns: The role of transparency

Using a sample of countries that require timely disclosures of insider trades, I investigate the effect of country‐level institutions that promote transparency on the extent to which aggregate insider trades predict market returns. I find that financial information transparency mitigates the predictive content of aggregate insider trades when markets are more likely to deviate from fundamentals (i.e., during market fads), and when there is greater co‐movement in stock prices. In contrast, there is some evidence that governance and investor protection mitigate the association between aggregate insider trades and future earnings surprises. Hence, holding constant the timely disclosures of insider trades, other capital market institutions play complementary roles in mitigating the informational frictions that give rise to the predictive content of aggregate insider trades.     

Insider Trading and the Bid-Ask Spread

This study examines the intertemporal and cross-sectional association between the bid-ask spread and insider trading. Empirical results from the cross-sectional regression analysis reveal that market makers establish larger spreads for stocks with a greater extent of insider trading. The time-series regression analysis, however, finds no evidence of spread changes on insider trading days. These results suggest that although market makers may not be able to detect insider trading when it occurs, they protect themselves by maintaining larger spreads for stocks with a greater tendency of insider trading. The results also reveal that market makers establish larger spreads when there are unusually large transactions. In addition, this study finds that spreads are positively associated with risk and negatively with trading volume, the number of exchange listings, share price, and firm size.
