融资首选定向发行可转债

股市的持续下跌．导致增发、配股等必须以股价为参考的再融资体系的价格重心下降，而可转债属于债券，并不直接牵涉到股价且发行量大，尤其是定向发行可转债的方式，可以直接避免让二级市场“失血”，在再融资恢复后将更受企业原股东的欢迎。对于符合内地企业海外上市规定的企业来说，如果等不及国内的融资排队，也完全可以通过在海外市场二次挂牌的方式，通过定向发行可转债进行再融资。     

上市公司发行可转债影响因素的实证研究

可转债、配股和增发已经成为上市公司再融资的三大方式,公司选择发行可转债受众多因素的影响,本文根据以前研究成果选择了资产负债率、公司规模、发行规模、第一大股东持股比例等因素运用logistic分析对可转债的发行进行实证研究,并根据研究结果给出相应的建议和对策。     

成功增发有赖机构投资者关键在于拿捏增发时机并掌握合理的定价策略

加息以及可能进入加息周期的预期使国内去年火爆的可转债融资热潮骤然降温。而增发的门槛比配股低，并且额度没有限制，有可能超过配股成为上市公司再融资的主要手段。我们研究发现，目前战功的增发已越来越依赖机构投资者的作为。     

怎样投资可转换债券

对投资者而言，可转债的最大优点是可选择性，即可以选择持有债券到期，领取利息收入；可以在二级市场卖出债券，获取价差；也可以转换成股票。如果股票价格下跌，投资者可以选择到期还本付息，这可以帮助投资者规避股票下跌导致的损失，而当股市上涨时，投资者又可以选择转股获得股价上涨带来的收益。在市道低迷时，它又可以通过调整转股价给投资者带来收益。一般来讲，可转换债券的转股比例的确定主要依据转股前一个周期（如２０天）股票的平均价格高低。由于现在股票价格比较低，所以转股比例会较高，而且由于股票价格如果低于转股价格，…     

预期转股冲击与企业杠杆调整——基于可转债的断点回归分析

股票价格高于转股价格时可转换债券内嵌期权由虚值变成实值状态,可转债持有者可能自愿转为股票对企业而言是一种外生的杠杆率下降冲击。文章从可转债预期转股冲击视角,采用断点回归分析的方法,探讨预期转股冲击对企业杠杆调整的作用程度和影响路径,同时分析预期转股冲击对不同来源负债的影响差异,并检验债务累积风险不同的企业杠杆调整的异质性。研究发现：企业增加当期杠杆率以应对预期转股冲击,预期转股冲击通过增加股价信息含量和提高股票流动性的路径影响企业杠杆调整,其显著提高经营杠杆而不影响金融杠杆。进一步分组检验表明,债务累积风险低的企业对预期转股冲击导致的预期杠杆率下降更为敏感,积极调整企业杠杆率,预期转股冲击不会叠加债务累积风险高的企业杠杆率。可转债融资工具有助于企业实现稳杠杆。     

可转换债券隐含波动率测度及其内在价值评估——以上市商业银行可转换债券为例

可转换债券具有债权性、股权性与期权性等多重属性，其隐含波动率测度是进行债券定价及实施风险管理的重要手段。采用实证分析与市场观察比较方法，构建二叉树模型、分位数回归模型，选取10家上市商业银行为样本，通过引入修正无风险利率考察银行可转债理论价值与市场价格偏离幅度，并对可转债隐含波动率与正股价格影响关系展开分析。实证结果表明：银行可转债的理论价值略低于市场价格，其可转债的隐含波动率与正股股价存在负相关性，隐含波动率在一定程度上解释了市场中的可转债溢价现象。基于此，应完善可转债定价机制，优化可转债发行条款，提高可转债定价的信息化集成水平。     

现金股利重要性证明

上市公司普遍分红少,多以配股和转配股来代替.该现象在2000年以前尤为明显.在2000年以后由于据闻管理层将出台有关现金利润分配与融资相联系的政策规定,故一些公司增加了现金分红.2004年管理层终于出台<关于加强社会公众股股东权益保护的若干规定>,明确指出:上市公司最近三年未进行现金利润分配的,不得向社会公众增发新股,发行可转换公司债券或向原有股东配售股份.     

可转换公司债券投资策略研究

可转换公司债券赋予持有人在发债后一定时间内,选择是否依约定的条件将持有的债券转换为发行公司的股票或者另外一家公司股票的权利。可转债包含了债券价值和股票期权价值,因此具有"下跌风险有界,上涨收益巨大"的投资优势。本文重点从宏观经济周期、转债发行条款、纯债溢价率及转股溢价率、发行公司基本面等方面分析影响可转债价格的因素,并结合国内市场探讨可转债投资策略。

上市公司股权结构与再融资行为研究

以2000—2002年末进行增配股的上市公司为样本，用实证的方法分析股权结构与股权融资方式的关系，以及融资前后股权结构的变化。结果显示选择配股的上市公司流通股占总股本比例明显高于选择增发的上市公司流通股所占比例，并且配股和增发新股能够直接导致上市公司股权结构的变动。使上市公司股权结构进一步优化。     

中国上市公司内外融资的顺序偏好

文章指出,对中国上市公司中的股份异质公司而言,若不考虑关联交易因素,内源融资逊色于外源融资,其所偏爱的股利政策为现金分红,这意味着中国证券监督管理委员会将现金分红作为上市公司申请配股或增发先决条件的现行规定可能并不妥当,加强对上市公司关联交易的监管才是问题的根本。在有报告盈余的情况下,这类公司会趋向于大规模派发现金股利,除非其报告盈余存在虚假或日后存在向其控股股东输送利润的可能,因此投资者及相关政府部门可利用这一特性低成本地甄别其企业会计报表的真伪及未来发生非对等关联交易的可能性。     

Anatomy of option features in convertible bonds

Several earlier theoretical studies on the optimal issuer's calling policy of a convertible bond suggest that the issuer should call the bond as soon as the conversion value exceeds the call price. However, empirical studies on actual cases of calling by convertible bond issuers reveal that firms “delayed” calling their convertible bonds until the conversion value well exceeded the call price. In this paper, we construct valuation algorithms that price risky convertible bonds with embedded option features. In particular, we examine the impact of the soft call and hard call constraints, notice period requirement and other factors on the optimal issuer's calling policy. Our results show that the critical stock price at which the issuer should optimally call the convertible bond depends quite sensibly on these constraints and requirements. The so‐called “delayed call phenomena” may be largely attributed to the underestimation of the critical call price due to inaccurate modeling of the contractual provisions. © 2004 Wiley Periodicals, Inc.

我国上市公司股利政策信息内涵的实证研究

股利政策是现代公司理财的三大核心内容之一,它是公司融资、投资活动的延续,是其理财行为的必然结果。本文采用事件研究法对我国上市公司股利政策的信息内涵进行实证研究,以1997-2004年度上海证券交易所上市的A股股票的股利分配行为为研究对象,考察我国上市公司的股利政策是否传递了信息、传递了怎样的信息这两个方面的内容;同时,针对不同的股利支付方式进行了信息传递的敏感性测试。     

低现金股利政策、股东财富与控股股东决策

根据Jensen的自有现金流量假说,在不考虑股票回购条件下,将公司支付的现金股利数量低于自由现金流量定义为低现金股利政策.研究显示,低现金股利政策不利于股东财富最大化,在低现金股利政策范围内,提高现金股利会提高股东财富.但从控股股东财富最大化出发,实施低现金股利政策有助于实现其获取控制权私有收益以本身的财富最大化.     

On the valuation of warrants

This article addresses a misconception in the literature concerning the valuation of warrants when a warrant is treated as an option on the stock of the underlying firm. The magnitude and timing of the impact of a warrant issue on the underlying stock price and on the wealth of the firm's shareholders is examined within a continuous‐time arbitrage‐free economy. In particular, it is shown that the stock price of the underlying firm conditionally reflects dilution at all times following the announcement of a warrant issue and notwithstanding that the warrants might not even have been issued yet. Valuing a warrant or convertible security as an option on the post‐announcement underlying stock price means there is no need for any explicit adjustment for dilution to be made to the chosen option pricing model. © 2002 Wiley Periodicals, Inc.

基于迎合理论的中国上市公司现金股利变更性研究

基于现金股利变更的动态视角,利用2000－2013年度中国证券市场的数据,分别从市场整体迎合与上市公司单个迎合方面,实证检验了迎合理论在中国证券市场的适用性。研究发现,迎合理论能够作为解释中国上市公司分配现金股利的原因。从市场整体状况来看,上市公司的当年度现金股利意愿与上年度的市场股利溢价之间存在明显的相同趋势,而从上市公司状况来看,若上市公司的现金股利意愿与市场股利溢价水平之间的差距越大,则更有可能变更现金股利形式以迎合证券市场投资者的需求。     

Taxes,Order Imbalance and Abnormal Returns around the ex‐Dividend day

A costly arbitrage model, developed for the Australian imputation tax system, shows that stocks paying dividends with a tax credit are likely targets for ex‐dividend arbitrage. We show that order imbalance, based on the direct observation of buyer and seller initiated trades, is a key factor in price movements around the ex‐dividend day. Buying pressure before the ex‐dividend day aimed at capturing the dividend and tax credit leads to an increase in prices that subsequently reverse in the ex‐dividend period. This effect is concentrated in those stocks distributing a tax credit with their dividend payments. The price pressure resulting from order imbalance is substantially higher around the ex‐dividend day relative to the effect observed outside this period. Our results reject the model of Frank and Jagannathan ( 1998 ) that bid‐ask bounce is responsible for the ex‐day premium and provide support for explanations based on taxes, transaction costs, and incomplete price adjustment on the ex‐day.     

How and Why Do Firms Adjust Their Cash Holdings toward Targets? Evidence from China

We examine the dynamic adjustment of cash holdings of publicly traded Chinese firms during 1998–2006. The empirical evidence is supportive of the dynamic trade-off theory of cash holdings. In particular, there is strong evidence of asymmetric adjustments, i.e., adjustments from above the target are significantly faster than those from below. Moreover, the speeds of adjustment (SOA) are heterogeneous for firms facing differential adjustment costs. More specifically, the adjustment speed is higher in firms with bank lines of credit, positively related to the deviation from the target, but it is negatively related to firm size. Furthermore, in terms of adjustment method, firms make adjustments to their targets primarily through debt and equity financing when they are in cash shortage, On the other hand, the dividend payments play a minimal role in it. Lastly, in terms of motives for adjustment, we find that the precautionary motive arising from financial constraints well explains the cash holdings adjustment behaviors of Chinese listed firms.     

Influence of dividend tax policy tied to investment horizon on stock price stability: Evidence from the 2015 dividend tax reform in China

We examine how the dividend tax cut policy tied to the investment horizon enforced on September 8, 2015, influences stock price stability in China's A-share market. As the new dividend tax policy waives the tax on cash dividends for investors holding a stock for more than a year, it encourages long-term investment behavior. From 2013 to 2017, we find that stock turnover, return volatility, and turnover volatility decrease after the policy enforcement, especially for stocks with high dividend yields. This result shows that dividend tax reforms increase investors' stock investment horizons and help stabilize the market. However, our findings demonstrate that stock crash risk increases after policy enforcement. Further analysis shows that earnings management through real activities manipulation for stocks with a higher dividend yield contributes to an increase in stock crash risk. Therefore, one externality of the dividend tax cut policy tied to the investment horizon is that top managers of firms with a higher dividend yield may take advantage of investors' passive longer-term investment behavior and engage in more earnings management. This result suggests that regulatory agencies should pay attention to top managers' earnings management behavior after enacting policies that encourage long-term investment.
