Pub Date : 2017-01-30 DOI: 10.2139/ssrn.2154658
Susan Ji, J. Martin, Chelsea Yao
We contribute to the growing debate on the relation between macroeconomic risk and stock price momentum. Not only is momentum seasonal, so is its net factor exposure. We show that winners and losers only differ in macroeconomic factor loadings in January, the one month when losers overwhelmingly outperform winners. In the remainder of the year, when momentum does exist, winner and loser factor loadings offset nearly completely. Furthermore, the magnitude of macroeconomic risk premia appears to seasonally vary contra momentum. In contrast, the relatively new profitability factor does a much better job of capturing the described seasonality.
我们对宏观经济风险和股票价格动量之间的关系进行了越来越多的讨论。动量不仅是季节性的,其净因素敞口也是如此。我们的研究表明,赢家和输家只是在1月份的宏观经济因素负荷上有所不同,而在这个月份,输家的表现明显优于赢家。在今年剩下的时间里,当势头确实存在时,赢家和输家的因素负荷几乎完全抵消。此外,宏观经济风险溢价的幅度似乎与动量相反,呈季节性变化。相比之下,相对较新的盈利能力因子在捕捉所描述的季节性方面做得更好。

This paper focuses on how changes in financial plumbing of the markets may impact themonetary policy options as central banks contemplate lift off from zero lower bound (ZLB). Under the proposed regulations, banks will face leverage ratio constraints. As a result of quantitative easing (QE), banks want balance sheet “space” for financial intermediation/ non-depository activities. At the same time, regulatory changes are boosting demand for high quality liquid assets. The paper also discusses the role of repo markets and the importance of collateral velocity and the need to avoid wedges between repo and monetary policy rates when leaving ZLB.
本文关注的是,随着央行考虑从零利率下限(ZLB)上调,市场金融管道的变化如何影响货币政策选择。根据拟议的监管规定,银行将面临杠杆率的限制。作为量化宽松(QE)的结果,银行希望资产负债表上有“空间”用于金融中介/非存款活动。与此同时,监管改革正在提振对高质量流动资产的需求。本文还讨论了回购市场的作用和抵押品速度的重要性,以及在离开ZLB时避免回购与货币政策利率之间出现楔子的必要性。

Dissecting the Low Volatility Anomaly 剖析低波动异常
Pub Date : 2013-08-14 DOI: 10.2139/ssrn.2140054
Bradford D. Jordan, Timothy Riley
We find the low volatility anomaly is present in all but the smallest of stocks. Portfolios can be formed on either total or idiosyncratic volatility to take advantage of this anomaly, but we show measures of idiosyncratic volatility are key. Standard risk-adjusted returns suggest that there is no low volatility anomaly from 1996 through 2011, but we find this result arises from model misspecification. Caution must be taken when analyzing high volatility stocks because their returns have a nonlinear relationship with momentum during market bubbles.
我们发现,除了最小的股票外,所有股票都存在低波动性异常。可以根据总波动率或特殊波动率来形成投资组合,以利用这种异常,但我们表明,衡量特殊波动率是关键。标准风险调整收益表明1996 - 2011年不存在低波动异常,但我们发现这一结果是由模型错配引起的。在分析高波动性股票时必须谨慎,因为它们的收益与市场泡沫期间的动量呈非线性关系。

Price Discovery in the Stock and Corporate Bond Markets 股票和公司债券市场的价格发现
Pub Date : 2012-11-24 DOI: 10.2139/ssrn.2140186
Yifei Mao
This paper uses intraday U.S. bond transaction and stock quote data to investigate whether corporate bonds lead stocks in price discovery of underlying firm value. I use Hasbrouck's (1995) "information share" approach to determine the relative contribution of corporate bonds to price discovery. Based on a sample of 214 firms, I find that corporate bond markets contribute 12.6% on average to price discovery from 2009 to 2011. Corporate bond market price discovery increases with the riskiness of the underlying firm value, and is related to contemporaneous market conditions. The findings are consistent with the informed trading theory and Merton (1973) model.
本文使用美国债券交易和股票报价数据来研究公司债券是否会导致股票价格发现潜在的公司价值。我用的是Hasbrouck的(1995)利用“信息共享”方法确定公司债券对价格发现的相对贡献。基于214家公司的样本,我发现从2009年到2011年,公司债券市场对价格发现的平均贡献为12.6%。公司债券市场价格发现率随着潜在公司价值的风险而增加,并与当时的市场状况有关。这些发现与知情交易理论和默顿(1973)模型是一致的。

Likely Benefits from HIFO Accounting HIFO会计可能带来的好处
Pub Date : 2012-09-25 DOI: 10.2139/ssrn.2151955
Robert J. Atra, Yuntaek Pae
New IRS rules on accounting for cost basis often impose on investors a decision regarding cost basis when selling shares. We investigate in a very practical way the likely benefits from choosing the highest-in, first-out (HIFO) method for tracking shares. Our results show that for realistic scenarios where investors plan for retirement, HIFO accounting can add about 2% to the investor’s total wealth at the retirement date. Above average tax rates and greater volatility increase the value of using HIFO accounting.
美国国税局关于成本基础会计的新规定往往要求投资者在出售股票时就成本基础作出决定。我们以一种非常实际的方式调查了选择最高进先出(high -in, first-out, HIFO)方法跟踪股票可能带来的好处。我们的研究结果表明,对于投资者计划退休的现实情况,HIFO会计可以在退休之日为投资者的总财富增加约2%。高于平均水平的税率和更大的波动性增加了使用HIFO会计的价值。

Bank Dividends and Signaling to Information-Sensitive Depositors 银行分红和对信息敏感的存款人的信号
Pub Date : 2012-08-31 DOI: 10.2139/ssrn.2139725
C. Forti, R. Schiozer
This study investigates whether banks use dividends to signal asset quality and liquidity to their debtholders. We exploit an exogenous shock to the asset opaqueness and perception of risks of Brazilian banks caused by the global financial turmoil of 2008. Our empirical identification takes advantage of the cross-sectional heterogeneity of types of depositors in Brazilian banks and the existence of several owner-managed banks (for which shareholder-targeted signaling is implausible) to identify that information-sensitive depositors (institutional investors) are targets of dividend signaling by banks. These costly signaling efforts are particularly strong during financial crises when asset opaqueness, informational asymmetry and depositors’ concerns regarding bank liquidity are exacerbated. From a policy perspective, our results favor the imposition of limits on bank dividends during financial crises, because the banks’ need to signal their financial health through dividends during crises intensifies the pro-cyclical effects of bank capital on lending.
本研究探讨银行是否使用股息向其债权人发出资产质量和流动性的信号。我们利用了2008年全球金融动荡对巴西银行的资产不透明度和风险认知造成的外生冲击。我们的实证识别利用了巴西银行存款人类型的横断面异质性和几家所有者管理银行的存在(对这些银行来说,以股东为目标的信号是不可信的)来识别信息敏感的存款人(机构投资者)是银行股息信号的目标。在金融危机期间,当资产不透明、信息不对称以及存款人对银行流动性的担忧加剧时,这些代价高昂的信号传递工作尤为重要。从政策角度来看,我们的研究结果支持在金融危机期间对银行股息施加限制,因为银行需要在危机期间通过股息表明其财务健康状况,这加剧了银行资本对贷款的顺周期效应。

The purpose of the regulated halts on stock exchange markets is to spread the information on the market and to protect the interests of the small shareholders. The aim of this work is to empirically investigate the price limits on the French stock exchange market. We analyze the impact of such halts on the main market factors: return, volatility and volume. Our study concerns intraday data relating to securities that belong to the CAC40 stock index over the period January 1998-December 2001. Finally, we put forward a mitigated effectiveness of the price limits, depending on the period.

New Properties of the Old Present Value Operator 旧现值运算符的新属性
Pub Date : 2012-08-29 DOI: 10.2139/ssrn.2138379
Stephen A. Buser
Advances in computing technology have greatly enhanced methods for numerical calculations of present value and related measures such as duration and convexity. Nevertheless, closed form solutions continue to play an important role both in the classroom and in the real world. For example, it is well known that if r is the rate of discount and if C1 denotes the value in period 1 for a cash flow that grows at constant percentage rate, g, then the present value of the future cash flow can be represented as C1 / (r – g). Yet how many students or practitioners, and dare we ask how many finance professors, are aware that the duration of a perpetual cash flow that grows at a uniform geometric rate can be represented as (1 r) / (r –g) ? For that matter, how widely is it known that a simple closed form solution exists for the present value of a cash flow that exhibits cyclical variation over time or a cash flow that grows by a constant dollar amount each period rather than by a constant percentage amount? The objective of this paper is to demonstrate that these results, and countless others, can be derived from one simple but previously under developed property of the traditional present value operator.
计算技术的进步极大地提高了现值的数值计算方法和相关的测量方法,如持续时间和凸度。然而,封闭形式的解决方案继续在课堂和现实世界中发挥重要作用。例如,众所周知,如果r是贴现率和C1表示1期的价值增长速度常数比例的现金流,g,然后未来现金流的现值可以表示成C1 / (r - g),但有多少学生或从业人员,我们敢问多少金融教授,意识到一个永恒的现金流持续时间的增长速度可以表示成统一的几何(1 r) / (r - g) ?就这个问题而言,对于现金流量的现值存在一个简单的封闭形式的解决方案,它随着时间的推移表现出周期性变化,或者现金流量在每个时期以恒定的美元数量增长,而不是以恒定的百分比数量增长,这一点广为人知吗?本文的目的是证明这些结果,以及无数其他结果,可以从传统现值算子的一个简单但以前未开发的性质中得出。

Heir to the Throne: Choice of the Replacement CEO in Unexpected CEO Turnover 王位继承人:CEO意外离职时的替代CEO选择
Pub Date : 2012-08-27 DOI: 10.2139/ssrn.2140136
Mia L. Rivolta
We examine the roles board of directors can play in CEO succession planning, by asking the questions, whom should the firm choose as replacement CEOs in unexpected CEO turnover, and what is the impact of this decision on shareholder wealth? More specifically, we build on the director expertise literature and investigate whether the selection of replacement CEOs from the board facilitates a smoother transition and maintain firm continuity. We focus on unexpected CEO turnover, as it provides an exogenous setting allowing us to examine the impact of the CEO replacement decision on costs associated with the succession and on shareholder wealth post succession. Overall, our results indicate that in addition to its monitoring and advising roles, the board of directors can also oversee the company when needed. While selecting replacement CEO from existing board members may allow the company to quickly fill the CEO position, thereby reducing uncertainty and transitional costs (measured by new CEO turnover, senior management turnover and delay), it may not be beneficial to shareholders. We provide evidence that replacing departing CEO with a board member is negatively associated with stock performance for up to two years.
我们考察了董事会在CEO继任计划中可以发挥的作用,通过提出以下问题:在CEO意外离职时,公司应该选择谁来接替CEO ?这一决定对股东财富的影响是什么?更具体地说,我们以董事专业知识文献为基础,调查从董事会中选择替代ceo是否有助于更平稳的过渡并保持公司的连续性。我们关注意外的CEO更替,因为它提供了一个外生环境,使我们能够检查CEO更替决策对与继任相关的成本和继任后股东财富的影响。总体而言,我们的研究结果表明,董事会除了发挥监督和建议的作用外,还可以在需要时对公司进行监督。虽然从现有董事会成员中选择替代CEO可能会让公司迅速填补CEO职位,从而减少不确定性和过渡成本(以新任CEO离职、高级管理层离职和延迟衡量),但这可能对股东不利。我们提供的证据表明,用董事会成员取代即将离职的首席执行官与股票表现负相关的时间长达两年。

Overvaluation, Financial Opacity and Crash Risk 估值过高、金融不透明和崩溃风险
Pub Date : 2012-08-23 DOI: 10.2139/ssrn.2135704
H. Wang, Wei Du
Equity is overvalued when its market value is far above its underlying value. Jensen (2005) proposes that overvaluation leads to value-destroying opportunistic earnings management. In this study I examine how equity overvaluation affects a firm’s financial opacity and its stock crash risk. I find that overvalued firms tend to use more earnings management (higher financial opacity) and they do so to conceal firm specific information from the investors, it is especially so for substantially overvalued firms. On the contrary, undervalued firms are willing to provide more firm-specific information to the market. Furthermore, I find that the reported ROEs of substantially overvalued firms are significantly higher than the unmanaged ROEs. But no significant difference of reported ROEs and unmanaged ROEs is detected among substantially undervalued firms. In addition, I show that overvalued firms have higher crash risk than otherwise identical but non-overvalued firms. At last, I find that a powerful CEO (proxy by CEO and chairman duality) can restrain an overvalued firm’s urge to manage earnings more aggressively.
当股票的市场价值远高于其潜在价值时,股票就被高估了。Jensen(2005)提出高估会导致破坏价值的机会主义盈余管理。在本研究中,我考察了股票估值过高如何影响公司的财务不透明度及其股票崩盘风险。我发现估值过高的公司倾向于使用更多的盈余管理(更高的财务不透明度),他们这样做是为了向投资者隐瞒公司的具体信息,对于估值过高的公司尤其如此。相反,被低估的公司愿意向市场提供更多公司特有的信息。此外,我发现严重高估的公司报告的净资产收益率明显高于未管理的净资产收益率。但在被严重低估的公司中,报告的净资产收益率和未管理的净资产收益率没有显著差异。此外,我还表明,估值过高的公司比其他方面相同但未估值过高的公司有更高的崩溃风险。最后,我发现一个强大的CEO(由CEO和董事长双重代理)可以抑制被高估公司更积极地管理收益的冲动。
