A Comparative Analysis of Financial Professionals’ Perception of the Level of Graduating Business Student Retirement Planning Familiarity, Motivation, and Preparedness 金融专业人士对商科学生退休计划熟悉程度、动机及准备程度之认知比较分析
M. Power, Jonathan M. Hobbs
Academic, government, employer, and individual interest in personal financial literacy have mushroomed as financial decision making has become more complex, costly, and less paternalistic. Financial illiteracy in America manifests in many ways, including low levels of personal saving, high levels of personal debt, negative financial wealth, a decline in standard of living, and increased demand on social safety networks. For college students, of particular concern is the high level of public and private debt accrued while working toward a degree. It is important to understand how prepared households are for retirement planning decisions and which factors can improve their preparedness. We show that financial education is impactful in reducing financial illiteracy, and provides evidence that taking a personal risk management and insurance course helps to prepare college students to make retirement decisions. Second, we provide evidence that life stage explains differences (similarities) in how professionals self-rate the importance, familiarity, and motivation to plan and save for retirement versus their opinion on how vital the questions should be to students. Finally, additional evidence is provided showing that demographic characteristics explain differences in the importance and motivation to plan and save for retirement and in the familiarity that respondents have with retirement planning and saving products.
学术界、政府、雇主和个人对个人理财知识的兴趣如雨后春笋般涌现,因为财务决策变得越来越复杂、成本越来越高、家长作风越来越少。美国的金融文盲表现在很多方面,包括低水平的个人储蓄、高水平的个人债务、负的金融财富、生活水平的下降以及对社会保障网络的需求增加。对于大学生来说,特别值得关注的是在攻读学位的过程中积累的高额公共和私人债务。重要的是要了解家庭对退休计划决策的准备情况,以及哪些因素可以提高他们的准备程度。我们证明了金融教育在减少金融文盲方面是有影响的,并提供了证据表明,参加个人风险管理和保险课程有助于大学生做好退休决策的准备。其次,我们提供的证据表明,人生阶段解释了专业人士对退休计划和储蓄的重要性、熟悉程度和动机的自我评价与他们对这些问题对学生的重要性的看法的差异(相似之处)。最后,提供了额外的证据,表明人口特征解释了重要性和动机的差异,为退休计划和储蓄,并在熟悉的受访者对退休计划和储蓄产品。

Are Individual or Institutional Investors the Agents of ‎Bubbles?‎ 个人投资者还是机构投资者是泡沫的推动者?‎
Pub Date : 2015-07-17 DOI: 10.2139/ssrn.2023766
J. Choi, Haim Kedar-Levy, S. Yoo
Behavioral bubble models typically assume that uninformed trend-chasers, presumably individual investors, cause bubbles, while informed contrarian investors such as institutions, trade against bubbles. DeLong et al. (1990a) highlight that to be considered a “bubble”, the mis-pricing must prevail in a large, diversified portfolio. To meet this criterion, we use a unique dataset of all transactions by investor type for all non-financial Korean firms, and find evidence at odds with such assumptions. Domestic individual investors systematically apply aggressive contrarian trades, while foreign and some domestic institutions are mostly trend-chasers. These findings suggest that institutional investors rather than individuals are agents of bubbles.
行为泡沫模型通常假设,不知情的趋势追逐者(大概是个人投资者)造成了泡沫,而知情的反向投资者(如机构)则在做逆泡沫交易。DeLong等人(1990a)强调,要被认为是“泡沫”,错误定价必须在一个大型的、多元化的投资组合中普遍存在。为了满足这一标准,我们使用了所有非金融韩国公司按投资者类型划分的所有交易的独特数据集,并找到了与此类假设不一致的证据。国内个人投资者系统地进行激进的反向交易,而国外和一些国内机构大多是趋势追逐者。这些发现表明,机构投资者而不是个人是泡沫的推动者。

Smile in Motion: An Intraday Analysis of Asymmetric Implied Volatility 运动中的微笑:非对称隐含波动率的日内分析
Pub Date : 2015-05-01 DOI: 10.2139/ssrn.2022261
Martin Wallmeier
We present a new method to measure the intraday relationship between movements of implied volatility smiles and stock index returns. It exploits a specific characteristic of the smile profile in high-frequency data. Using transaction data for EuroStoxx 50 options from 2000 to 2011 and DAX options from 1995 to 2011 (14 million transactions), we find that the intraday evolution of volatility smiles is generally not consistent with traders' rules of thumb such as the sticky strike or sticky delta rule. On average, the impact of index return on implied volatility is 1.3 to 1.5 times stronger than the sticky strike rule predicts. The main factor driving variations of the adjustment factor is the index return. Our results have implications for option valuation, hedging and the understanding of the leverage effect.
本文提出了一种新的方法来衡量隐含波动率的变动与股票指数收益之间的日内关系。它利用了高频数据中微笑轮廓的特定特征。利用2000年至2011年欧洲斯托克50期权和1995年至2011年DAX期权(1400万笔交易)的交易数据,我们发现波动率的日内演变通常不符合交易者的经验法则,如粘性罢工或粘性增量规则。平均而言,指数回报对隐含波动率的影响是粘性罢工规则预测的1.3至1.5倍。驱动调整因子变化的主要因素是指数收益。我们的研究结果对期权估值、套期保值和杠杆效应的理解具有启示意义。

Does Realized Skewness Predict the Cross-Section of Equity Returns? 已实现偏度能否预测股票收益的横截面?
Pub Date : 2015-03-09 DOI: 10.2139/ssrn.1898735
Diego Amaya, Peter F. Christoffersen, Kris Jacobs, Aurelio Vasquez
We use intraday data to compute weekly realized moments for equity returns and study their time-series and cross-sectional properties. Buying stocks in the lowest realized skewness decile and selling stocks in the highest realized skewness decile generates an average return of 19 basis points the following week with a t-statistic of 3.70. This result is robust across a wide variety of implementations and is not captured by the Fama-French and Carhart factors. The relation between realized kurtosis and next week׳s stock returns is positive but not always significant. We do not find a strong relation between realized volatility and next week׳s stock returns.
我们使用日内数据来计算股票回报的每周实现时刻,并研究它们的时间序列和横截面属性。买入最低实现偏度十分位数的股票,卖出最高实现偏度十分位数的股票,在接下来的一周平均收益为19个基点,t统计量为3.70。这个结果在各种各样的实现中都是健壮的,并且不受Fama-French和Carhart因素的影响。已实现峰度与下周的股票收益呈正相关,但并不总是显著的。我们没有发现已实现波动率与下周的股票回报之间存在很强的关系。

(How) Do Taxes Affect Capital Structure? 税收如何影响资本结构?
Pub Date : 2015-02-05 DOI: 10.2139/ssrn.2022518
Andrew D. MacKinlay
Ignoring the cost of debt in firms’ financing decisions leads to an overstatement of the effect of taxes. Separately identifying the impact of the cost of debt, I find the effect of taxes on firms’ overall debt usage to be insignificant. Rather than influencing the total debt in firms’ capital structure, taxes affect the relative composition of debt. Firms shift from private intermediated debt to public bond debt in response to increases in marginal tax rates. Firms’ debt policy is most sensitive to tax rates in high interest rate environments.
在企业的融资决策中忽视债务成本会导致对税收影响的夸大。单独确定债务成本的影响,我发现税收对企业整体债务使用的影响是微不足道的。税收影响的不是企业资本结构中的总债务,而是债务的相对构成。企业从私人中介债务转向公共债券债务,以应对边际税率的提高。在高利率环境下,企业的债务政策对税率最为敏感。

Seeking Alpha, Getting Beta: A Comparison of Mutual and Hedge Fund Performance, Style Attribution and Active Management Fees 寻求阿尔法,获得贝塔:共同基金和对冲基金业绩、风格归因和主动管理费用的比较
Pub Date : 2014-11-11 DOI: 10.2139/ssrn.1999464
William R. McCumber
Utilizing several models and regression analytics I compare factor attribution, strategies, and active management fees for 11,394 U.S. equity mutual funds and a matched sample of hedge funds from 1994 to 2010. There is modest evidence to support alpha delivery by mutual and hedge fund managers though this critically depends upon model specification. Quantile regression analysis with a robust bootstrap procedure demonstrates that typical regressions at the means do not adequately describe manager skill and factor attribution, and that these findings are not driven by the short-sample problem or backfill bias. Specifically, manager skill is demonstrably different at the 20th and 80th percentiles. Hedge funds are more actively managed than mutual funds, and thus investors pay similar fees to mutual funds and hedge funds for active management services even when taking hedge fund performance fees into consideration.
利用几个模型和回归分析,我比较了从1994年到2010年11,394个美国股票共同基金和匹配的对冲基金样本的因素归因、策略和积极管理费用。有适度的证据支持共同基金和对冲基金经理的alpha交付,尽管这在很大程度上取决于模型规格。采用稳健的自举程序的分位数回归分析表明,典型的均值回归并不能充分描述经理技能和因素归因,并且这些发现不是由短样本问题或回填偏差驱动的。具体来说,管理者的技能在第20和第80百分位数上明显不同。对冲基金的管理比共同基金更积极,因此即使考虑到对冲基金的业绩费,投资者也要向共同基金和对冲基金支付类似的积极管理服务费用。

The Market for Directors’ and Officers’ Insurance 董事及高级职员保险市场
Stephen G. Fier, Andre P. Liebenberg
Directors’ and officers’ (D&O) liability insurance is a commonly used risk management tool for corporations both in the United States and abroad. While prior research has focused on the demand for D&O insurance and its role in corporate governance, there is an absence of literature on the supply side of the D&O market. Using the newly available D&O Insurance Coverage Supplement to insurers’ statutory filings, we develop a more comprehensive understanding of the D&O insurance market and of those firms that write D&O coverage. We develop and estimate a model of the decision to write D&O insurance and the extent of market participation. Our results suggest that there are significant operational and financial differences between firms that supply D&O insurance and those that do not. Several of these differences (specifically, size, diversification, and organizational form) are consistent with the predictions of the managerial discretion hypothesis.
董事和高级管理人员(D&O)责任保险是美国和国外公司常用的风险管理工具。虽然先前的研究主要集中在董事和行政管理保险的需求及其在公司治理中的作用,但缺乏关于董事和行政管理市场供应方面的文献。利用最新的董事及行政管理保险范围补充文件,我们对董事及行政管理保险市场和那些承保董事及行政管理保险的公司有了更全面的了解。我们开发并估计了D&O保险的决定和市场参与程度的模型。我们的研究结果表明,在提供D&O保险和不提供D&O保险的公司之间存在显著的运营和财务差异。其中一些差异(特别是规模、多样化和组织形式)与管理自由裁量权假说的预测是一致的。

An Improved Moving Average Technical Trading Rule II: Can We Obtain Performance Improvements with Short Sales? 改进的移动平均技术交易规则II:我们可以通过卖空获得业绩改善吗?
Pub Date : 2014-06-01 DOI: 10.2139/ssrn.1958906
Fotis Papailias, D. Thomakos
In this paper we extend the methodology of our earlier work (Papailias and Thomakos, 2011) on a modified moving average technical trading rule by allowing short sales. We show how short sales change the trading rule which now acts as a dynamic trailing "stop-and-reverse", instead of a dynamic trailing stop as in the context of "long-only" trades. Then we empirically examine the performance of our modification in the context of a "long/short" trading approach and discuss the differentiation and implications in strategy performance. We compare both the modified version of our trading rule with the standard moving average approach and also compare the long/short approach with the long-only approach of the earlier paper.
在本文中,我们通过允许卖空,扩展了我们早期工作(Papailias和Thomakos, 2011)的方法,即修改的移动平均技术交易规则。我们展示了卖空是如何改变交易规则的,它现在作为一个动态的跟踪“止损和反转”,而不是像“只做多”交易那样的动态跟踪止损。然后,我们在“多/空”交易方法的背景下实证检验了我们的修改的绩效,并讨论了策略绩效的差异和影响。我们将修改后的交易规则与标准移动平均线方法进行了比较,并将多/空方法与之前论文中只做多的方法进行了比较。

Liquidity Risk and Institutional Ownership 流动性风险与机构所有权
Pub Date : 2014-05-05 DOI: 10.2139/ssrn.1960625
C. Cao, Lubomir Petrasek
Institutional ownership affects the sensitivity of stock returns to changes in market liquidity (liquidity risk). Overall, institutional ownership lowers the liquidity risk of stocks. However, different types of institutions affect liquidity risk in opposite ways. Stocks held by hedge funds, especially levered hedge funds, as marginal investors are more sensitive to changes in market liquidity than comparable stocks held by other types of institutions or by individuals. In contrast, stocks held by banks are less sensitive to changes in aggregate liquidity. These findings are robust to alternative specifications that control for institutional preferences for different stock characteristics and risk.
机构所有权影响股票收益对市场流动性变化的敏感性(流动性风险)。总体而言,机构持股降低了股票的流动性风险。然而,不同类型的机构以相反的方式影响流动性风险。对冲基金持有的股票,尤其是杠杆对冲基金,作为边际投资者对市场流动性的变化比其他类型的机构或个人持有的可比股票更敏感。相比之下,银行持有的股票对总流动性的变化不那么敏感。这些发现对于控制不同股票特征和风险的机构偏好的替代规范是稳健的。
