摘要:由于金融行业正在向数据行业转型故衡量投资者拥有的各种资产数据的数量非常重要根据结构模型本文设计了一个截面度量本文展示了该度量方法如何不同于价格信息并使用它记录一个新的事实: 跟其他公司的数据相比大型高增长公司的数据正变得越来越丰富我们的结构模型为这种数据差异提供了解释:大型高增长公司的数据变得更有价值因为大公司变得更大增长放大了这些规模变化的影响
Abstract:Since the finance industry is transforming into a data industry, measuring the quantity of data investors have about various assets is important. Informed by a structural model, we develop such a cross-sectional measure. We show how our measure differs from price informativeness and use it to document a new fact: data about large high-growth firms is becoming increasingly abundant, relative to data about other firms. Our structural model offers an explanation for this data divergence: large high-growth firms data became more valuable, as big firms got bigger and growth magnified the effect of these changes in size.

摘要:本文认为在证券市场中寻求决策相关信息的公司使用直接披露机制(DRMs)是存在弊端的在这种环境下DRM增加了知情代理的外部选择如果代理拒绝DRM他就会让市场相信他是不知情的他可以以低价格冲击积极交易从而产生巨大的(非平衡)交易收益这种内源性的外部选项可能使使用DRM来筛选不知情的代理成为不可能当筛选是可能的如果外部选择的增加足够大完全依靠市场信息是最优的
Abstract:We establish limitations to the usage of direct revelation mechanisms (DRMs) by corporations seeking decision-relevant information in economies with securities markets. In this environment, posting a DRM increases the informed agents outside option: if the agent rejects the DRM, he convinces the market he is uninformed, and he can aggressively trade with low price impact, thereby generating large (off-equilibrium) trading gains. This endogenous outside option may make using a DRM to screen uninformed agents impossible. When screening is possible, solely relying on the market for information is optimal if the increase in outside option is sufficiently large.

of Indexing

摘要:本文通过基准模型发现指数投资是在标准理性预期下的均衡结果个人投资者参与金融市场会产生成本而那些采用指数方式投资的个人成本较低指数化投资成本的下降直接促进指数化投资的参与程度从而进一步降低了指数化投资的费率在均衡状态下这些价格效率的变化反过来又会进一步增加指数并提高非知情交易者的福利对于消息灵通的交易员来说与选股交易相比市场时机选择交易带来的交易收益占比更高
Abstract:We develop a benchmark model to study the equilibrium consequences of indexing in a standard rational expectations setting. Individuals incur costs to participate in financial markets, and these costs are lower for individuals who restrict themselves to indexing. A decline in indexing costs directly increases the prevalence of indexing, thereby reducing the price efficiency of the index and augmenting relative price efficiency. In equilibrium, these changes in price efficiency in turn further increase indexing, and raise the welfare of uninformed traders. For well-informed traders, the share of trading gains stemming from market timing increases relative to stock selection trades.

摘要:对冲基金头寸是拥挤交易的重要组成部分这些机构特别活跃有着高度集中头寸并且利用杠杆和卖空使用对冲基金持有的数据库我们衡量了个股层面的拥挤程度高拥挤度组合与低拥挤度组合的平均收益差异较大其收益来源也不同于其他传统风险因素此外对冲基金面临的拥挤往往是显著的它们有助于解释下行的尾部风险因为风险敞口较高的基金在行业困境期间经历了相对较大的下跌
Abstract:Hedge fund positions are an important component of crowded trades. These vehicles are particularly active, take highly concentrated positions, and utilize leverage and short sales. Using a database of hedge fund holdings, we measure the degree of security-level crowdedness. The difference between the average returns on portfolios sorted by high versus low crowdedness portfolios is sizable, and the variation in the realized portfolio returns is distinct from other traditional risk factors. Further, hedge fund exposures to crowdedness are often significant, and they help to explain downside tail risk, as funds with higher exposures experience relatively larger drawdowns during periods of industry distress.

摘要:我们提出了一种新的衡量套利活动的度量来检验套利者是否可以对股票市场产生不稳定的影响我们关注股价动量这是一个典型的正反馈策略的例子我们的理论预测它可能会破坏稳定我们的衡量标准被称为协动量Comentum指的是动量策略筛选的个股之间的高频异常回报的相关性当协动量较低时动量策略趋于稳定反映了套利者纠正的反应不足现象当协动量高时动量股的回报会强劲回升这反映了之前拥挤的动量交易的过度反应推动价格偏离基本面
Abstract:We propose a novel measure of arbitrage activity to examine whether arbitrageurs can have a destabilizing effect on the stock market. We focus on stock price momentum, a classic example of a positive-feedback strategy that our theory predicts can be destabilizing. Our measure, dubbed comomentum, is the high-frequency abnormal return correlation among stocks on which a typical momentum strategy would speculate. When comomentum is low, momentum strategies are stabilizing, reflecting an underreaction phenomenon that arbitrageurs correct. When comomentum is high, the returns on momentum stocks strongly revert, reflecting prior overreaction from crowded momentum trading that pushes prices away from fundamentals.

The Momentum Gap and Return Predictability

摘要:过去赢家和输家的形成期收益差我们称之为动量差Momentum Gap是动量策略收益的负向预测指标本文在美国股市发现了该现象后续在21个主要国际市场发现了一致的结果在控制了现有的预测因素后Momentum Gap增加一个标准偏差预示着每月动量回报的减少1.25%静态动量投资组合的这预测性可延长5年与随时间变化的投资者的偏差一致遵循简单的实时策略即只在Momentum Gap低于历史80%分位数时投资动量策略夏普比率为0.78
Abstract:The formation period return difference between past winners and losers, which I call the momentum gap, negatively predicts momentum profits. I document this for the U.S. stock market and find consistent results across 21 major international markets. A one-standard-deviation increase in the momentum gap predicts a 1.25% decrease in the monthly momentum return after controlling for existing predictors. This predictability extends up to 5 years for static momentum portfolios, consistent with time-varying investor biases. Following the simple real-time strategy of investing in momentum only when the momentum gap is below the 80th percentile delivers a Sharpe ratio of 0.78.

摘要:本文发现全球公募基金通过在国内持有跨国公司股票提供了大量的国际敞口如果考虑到企业的国际多元化国内基金的国际敞口平均增加了32个百分点我们发现间接国际风险敞口较高的基金在横截面和时间序列上的表现都更好这种影响主要是由基金经理投资跨国公司的能力而不是这些跨国公司的业绩驱动的我们的研究结果支持跨国公司的国际多元化降低了海外投资的交易和信息成本的假设
Abstract:We show that mutual funds worldwide provide substantial international exposure through their domestic holdings of multinationals. The international exposure of domestic funds increases, on average, by 32 percentage points when we consider international corporate diversification. We find that funds with higher indirect international exposure perform better in both the cross-section and the time series. This effect is primarily driven by the fund managers ability to invest in multinationals, rather than the performance of those multinationals. Our findings support the hypothesis that international diversification from multinationals reduces the transaction and information costs of investing abroad.

摘要:本文表明银行关系促进了企业环境社会和治理(ESG)政策具体而言银行更有可能向ESG政策与自己相似的借款人发放贷款并对借款人随后的ESG表现产生积极影响当银行的ESG评级显著高于借款人以及借款人是银行依赖者时它们的影响更明显我们利用贷款人之间的并购作为贷款人ESG标准外生变异的来源以缓解对内生性的担忧总的来说我们的研究首次证明了负责任的银行贷款和借款人ESG行为之间的相互作用
Abstract:We show that banking relationships promote corporate environmental, social, and governance (ESG) policies. Specifically, banks are more likely to grant loans to borrowers with ESG profiles similar to their own and positively influence the borrowers subsequent ESG performance. Their influence is more pronounced when (1) banks have significantly better ESG ratings than borrowers and (2) borrowers are bank dependent. We exploit M&A among lenders as a source of quasi-exogenous variation in the lenders ESG standard to alleviate endogeneity concerns. Overall, our study presents the first evidence on the interplay between responsible bank lending and borrowers ESG behavior.

摘要:印度在2007年引入了信用评分技术我们研究了两种在那里运营的银行新私人银行(NPBs)和国有公共部门银行(PSBs)在这项技术引入后不久NPBs开始在放贷前检查大多数借款人的信用评分PSBs很快对新借款人使用同样的方式但对以前的客户信用评分检查实行的很慢尽管不检查分数的贷款更有可能会违约我们指出信用评分技术的采用率差异的一个重要因素是过去银行结构和管理实践的粘性过去的实践阻碍了今天更好的实践
Abstract:India introduced credit scoring technology in 2007. We study its adoption by the two main types of banks operating there: new private banks (NPBs) and state-owned public sector banks (PSBs). Soon after the technology is introduced, NPBs start checking the credit scores of most borrowers before lending. PSBs do so equally quickly for new borrowers but very slowly for prior clients, although lending without checking scores is reliably associated with more delinquencies. We show that an important factor explaining the difference in adoption rates is the stickiness of past bank structures and managerial practices. Past practices inhibit better practices today.

摘要:为了达到短期基准贷款机构可能会改变他们的监管行为为短期主义溢出到企业部门提供一个渠道我们发现短期主义的贷款人明显更有可能对违约采取更严苛的措施这种行为在业绩基准明确经理对薪酬绩效高度敏感时表现明显但在他们面对强有力的股东治理时则不明显受影响的借款人更有可能更换贷款机构为重新谈判的贷款支付更高的息差并减少投资我们的研究结果表明银行经理在契约执行过程中为了满足收益基准会以关系资本换取提高收入的费用和期限变更。
Abstract:To meet short-term benchmarks, lenders may alter their monitoring behavior, providing a channel for short-termism to spill over to their borrowers. We find that short-termist lenders are significantly more likely to enforce covenant breaches. This behavior is pronounced when performance benchmarks are precise or salient, and when managers have high pay-performance sensitivity, but not when they face strong shareholder governance. Affected borrowers are more likely to switch lenders, pay higher spreads on renegotiated loans, and reduce investment. Our findings suggest that bank managers trade off relationship capital for income-boosting fees and term changes from covenant enforcement to meet earnings benchmarks.
