A discontinuity, or kink, at zero in the hedge fund net return distribution has been interpreted as evidence of managers manipulating returns to avoid showing small losses. Instead, we propose alternative explanations for this phenomenon. In particular, we show that incentive fees can mechanistically create a kink in the net return distribution. This mechanism accounts for almost the entire kink observed in the large, liquid Long-Short Equity style. Furthermore, we show that asset illiquidity and the bounding of yields at zero can generate distribution discontinuities as well. Therefore, we conclude that the observed hedge fund return discontinuities are not direct proof of manipulation.
对冲基金净回报分布在零处的不连续性或扭结,被解读为基金经理操纵回报以避免出现小亏损的证据。相反,我们对这一现象提出了不同的解释。特别是,我们表明,激励费用可以机械地创造一个扭结在净收益分配。这一机制几乎解释了在大型、流动性强的多空股票类型中观察到的全部扭结。此外,我们还证明了资产的非流动性和收益率在零处的边界也会产生分布不连续。因此,我们得出结论,观察到的对冲基金收益不连续不是操纵的直接证据。

Central counterparties (CCPs) are becoming central to over-the-counter (OTC) markets. A CCP limits counterparty risk but raises entry barriers. We analyze the trade-off between dealers’ equilibrium default risk and competition in an OTC market with imperfect competition and endogenous default probability. We find that (i) CCP members favor entry restrictions and binding risk controls as a device to commit to less competition, (ii) restricting entry maximizes welfare when dealers’ transfer risk efficiently relative to their market power, and (iii) free entry reaches the first-best welfare if the CCP can limit risk-taking.
中央交易对手(ccp)正成为场外交易(OTC)市场的核心。CCP限制了交易对手风险,但提高了进入门槛。本文分析了不完全竞争和内生违约概率的场外交易市场中交易商均衡违约风险与竞争的权衡关系。我们发现:(i) CCP成员倾向于限制进入和约束风险控制作为减少竞争的一种手段;(ii)当经销商相对于其市场力量有效地转移风险时,限制进入使福利最大化;(iii)如果CCP能够限制风险承担,自由进入将达到最佳福利。

The Cross-Section of Credit Risk Premia and Equity Returns 信用风险溢价与股票收益的横截面分析
Pub Date : 2013-05-03 DOI: 10.2139/ssrn.1883101

type="main"> We explore the link between a firm's stock returns and credit risk using a simple insight from structural models following Merton ( ): risk premia on equity and credit instruments are related because all claims on assets must earn the same compensation per unit of risk. Consistent with theory, we find that firms' stock returns increase with credit risk premia estimated from CDS spreads. Credit risk premia contain information not captured by physical or risk-neutral default probabilities alone. This sheds new light on the “distress puzzle”—the lack of a positive relation between equity returns and default probabilities—reported in previous studies.
我们利用Merton()的结构模型中的一个简单见解来探索公司股票收益和信用风险之间的联系:股权和信用工具的风险溢价是相关的,因为对资产的所有索赔权必须获得相同的单位风险补偿。与理论一致,我们发现公司的股票收益随着CDS价差估计的信用风险溢价而增加。信用风险溢价包含的信息并非仅由物理或风险中性违约概率捕获。这为“困境难题”——股票回报和违约概率之间缺乏正相关关系——提供了新的线索。

The Marginal Cost of Risk, Risk Measures, and Capital Allocation 风险的边际成本、风险度量和资本配置
Pub Date : 2013-05-01 DOI: 10.2139/ssrn.1787145
Daniel Bauer, George Zanjani
Financial institutions use risk measures to calculate the marginal capital cost when expanding the exposure to a certain risk within their portfolio. We reverse this approach by calculating the marginal cost based on economic fundamentals for a profit-maximizing firm and then by identifying the risk measure delivering the correct marginal cost. The resulting measure depends on context. Whereas familiar measures can be recovered in some circumstances, other circumstances yield unfamiliar forms. In all cases, the risk preferences of the institution’s claimants determine how the correct risk measure must weight various default states. Our results demonstrate that risk measures used for pricing and performance measurement should be chosen based on economic fundamentals and may not necessarily adhere to the mathematical properties typically imposed in the literature. This paper was accepted by Jerome B. Detemple, finance .
金融机构在扩大其投资组合中的某种风险敞口时,使用风险度量来计算边际资本成本。我们通过基于利润最大化企业的经济基本原理计算边际成本,然后通过确定提供正确边际成本的风险度量来逆转这种方法。结果度量取决于上下文。虽然在某些情况下可以恢复熟悉的措施,但在其他情况下会产生不熟悉的形式。在所有情况下,机构索赔人的风险偏好决定了正确的风险度量必须如何权衡各种违约状态。我们的研究结果表明,用于定价和绩效衡量的风险指标应该基于经济基本面来选择,而不一定要遵循文献中通常强加的数学性质。这篇论文被金融学的杰罗姆·b·德坦普尔接受。

Asset Prices with Heterogeneity in Preferences and Beliefs 偏好与信念异质性下的资产价格
Pub Date : 2013-05-01 DOI: 10.2139/ssrn.1365032
Harjoat S. Bhamra, R. Uppal
In this paper, we study asset prices in a dynamic, continuous-time, general-equilibrium endowment economy where agents have “catching up with the Joneses” utility functions and differ with respect to their beliefs (because of differences in priors) and their preference parameters for time discount, risk aversion, and sensitivity to habit. A key contribution of our paper is to demonstrate how one can obtain a closed-form solution to the consumption-sharing rule for agents who have both heterogeneous priors and heterogeneous preferences without restricting the risk aversion of the two agents to special values. We solve in closed form also for the the state-price density, the riskless interest rate and market price of risk; the stock price, equity risk premium, and volatility of stock returns; the term structure of interest rates; and the conditions necessary to obtain a stationary equilibrium in which both agents survive in the long run. The methodology we develop is sufficiently general that, as long as markets are complete, it can be used to obtain the sharing rule and state prices for models set in discrete or continuous time and for arbitrary endowment and belief updating processes.
在本文中,我们研究了一个动态的、连续时间的、一般均衡的禀赋经济中的资产价格,在这个经济中,代理人具有“追赶琼斯”的效用函数,并且在他们的信念(由于先验的差异)和他们对时间贴现、风险厌恶和习惯敏感性的偏好参数方面存在差异。本文的一个关键贡献是证明了如何在不将两个代理的风险厌恶限制为特定值的情况下,获得具有异质先验和异质偏好的代理的消费共享规则的封闭形式解。并对风险的国价密度、无风险利率和市场价格进行了封闭式求解;股票价格、股票风险溢价和股票收益的波动性;利率期限结构;以及获得稳定平衡的必要条件两个主体都能长期生存。我们开发的方法是足够普遍的,只要市场是完整的,它就可以用来获得在离散或连续时间内设置的模型以及任意禀赋和信念更新过程的共享规则和状态价格。

Forecasting Liquidity-Adjusted Intraday Value-at-Risk with Vine Copulas 用Vine Copulas预测流动性调整后的日内风险价值
Pub Date : 2013-04-29 DOI: 10.2139/ssrn.2013203
Gregor N. F. Weiß, Hendrik Supper
We propose to model the joint distribution of bid-ask spreads and log returns of a stock portfolio by using Autoregressive Conditional Double Poisson and GARCH processes for the marginals and vine copulas for the dependence structure. By estimating the joint multivariate distribution of both returns and bid-ask spreads from intraday data, we incorporate the measurement of commonalities in liquidity and comovements of stocks and bid-ask spreads into the forecasting of three types of liquidity-adjusted intraday Value-at-Risk (L-IVaR). In a preliminary analysis, we document strong extreme comovements in liquidity and strong tail dependence between bid-ask spreads and log returns across the firms in our sample thus motivating our use of a vine copula model. Furthermore, the backtesting results for the L-IVaR of a portfolio consisting of five stocks listed on the NASDAQ show that the proposed models perform well in forecasting liquidity-adjusted intraday portfolio profits and losses.
我们提出用自回归条件双泊松和GARCH过程来模拟买卖价差和对数收益的联合分布,用vine copuls来模拟依赖结构。通过从日内数据中估计收益和买卖价差的联合多元分布,我们将流动性和股票变动以及买卖价差的共性测量纳入到三种类型的流动性调整的日内风险价值(L-IVaR)的预测中。在初步分析中,我们记录了流动性的强烈极端变动,以及我们样本中公司买卖价差和对数回报之间的强烈尾部依赖,从而促使我们使用葡萄球菌模型。此外,对由5只纳斯达克上市股票组成的投资组合的L-IVaR进行回测结果表明,所提出的模型在预测流动性调整后的日内投资组合盈亏方面表现良好。

Overconfident Individual Day Traders: Evidence from the Taiwan Futures Market 过度自信的个人日内交易者:来自台湾期货市场的证据
Pub Date : 2013-04-23 DOI: 10.2139/ssrn.1944059
Wei-Yu Kuo, Tse-Chun Lin
A specific day-trading policy in Taiwan futures market allows an investigation of the performance of day traders. Since October 2007, investors who characterize themselves as “day traders” by closing their day-trade positions on the same day enjoy a 50% reduction in the initial margin. Because we can identify day traders ex ante, we have a laboratory to explore trading behavior without the contamination of potential behavioral biases. Our results show that the 3470 individual day traders in the sample incur on average a significant loss of 61,500 (26,700) New Taiwan dollars after (before) transaction costs over October 2007–September 2008. This implies that day traders are not only overconfident about the accuracy of their information but also biased in their interpretations of information. We also find that excessive trading is hazardous only to the overconfident losers, but not to the winners. Last, we provide evidence that more experienced individual investors exhibit more aggressive day trading behavior, although they do not learn their types or gain superior trading skills that could mitigate their losses.
台湾期货市场有一项特殊的即日交易政策,允许对即日交易者的表现进行调查。自2007年10月以来,将自己定义为“当日交易者”的投资者在同一天平仓,其初始保证金将减少50%。因为我们可以事先识别日内交易者,所以我们有一个实验室来探索交易行为,而不会受到潜在行为偏见的污染。我们的研究结果显示,在2007年10月至2008年9月期间,样本中的3470名个人日内交易者在扣除(扣除)交易成本后平均损失61,500(26,700)新台币。这意味着日内交易者不仅对信息的准确性过于自信,而且对信息的解释也有偏见。我们还发现,过度交易只对过度自信的输家有害,对赢家无害。最后,我们提供的证据表明,更有经验的个人投资者表现出更激进的日内交易行为,尽管他们没有学习他们的类型或获得可以减轻损失的卓越交易技巧。

Stock Return Serial Dependence and Out-of-Sample Portfolio Performance 股票收益序列依赖与样本外投资组合绩效
Pub Date : 2013-04-01 DOI: 10.2139/ssrn.1572526
V. DeMiguel, F. Nogales, R. Uppal
We study whether investors can exploit serial dependence in stock returns to improve out-of-sample portfolio performance. We show that a vector-autoregressive (VAR) model captures stock return serial dependence in a statistically significant manner. Analytically, we demonstrate that, unlike contrarian and momentum portfolios, an arbitrage portfolio based on the VAR model attains positive expected returns regardless of the sign of asset return cross-covariances and autocovariances. Empirically, we show, however, that both the arbitrage and mean-variance portfolios based on the VAR model outperform the traditional unconditional portfolios only for transaction costs below ten basis points.
我们研究投资者是否可以利用股票收益的序列依赖来改善样本外投资组合的绩效。我们证明了向量自回归(VAR)模型以统计显著的方式捕获股票收益序列依赖性。通过分析,我们证明,与逆向投资组合和动量投资组合不同,基于VAR模型的套利投资组合无论资产收益交叉协方差和自协方差的符号如何,都能获得正的预期收益。然而,我们的经验表明,套利和基于VAR模型的均值-方差投资组合只有在交易成本低于10个基点时才优于传统的无条件投资组合。

Asset Pricing with Heterogeneous Investors and Portfolio Constraints 异质投资者和投资组合约束下的资产定价
Pub Date : 2013-04-01 DOI: 10.2139/ssrn.1571526
G. Chabakauri
We evaluate the impact of portfolio constraints on financial markets in a dynamic equilibrium pure exchange economy with one consumption good and two CRRA investors that may differ in risk aversions, beliefs regarding the dividend process and portfolio constraints. Despite numerous applications, portfolio constraints are notoriously difficult to incorporate into dynamic equilibrium analysis without the restrictive assumption of logarithmic preferences. We provide a tractable solution method that yields new insights on the asset pricing implications of portfolio constraints such as limited stock market participation, margin requirements and short sales prohibition without restricting risk aversion parameters. We demonstrate that in a setting where one investor is unconstrained while the other faces an upper bound constraint on the proportion of wealth that can be invested in stocks the model generates countercyclical market prices of risk and stock return volatilities, procyclical price-dividend ratios, excess volatility and other patterns consistent with empirical findings. In a setting with margin requirements we demonstrate that under plausible parameters tighter constraints decrease stock return volatilities during the times when the constraints are likely to bind.
在一个动态均衡纯交换经济中,我们评估了投资组合约束对金融市场的影响,其中一个消费商品和两个CRRA投资者可能在风险厌恶、关于股息过程的信念和投资组合约束方面存在差异。尽管有许多应用,但如果没有对数偏好的限制性假设,将投资组合约束纳入动态均衡分析是出了名的困难。我们提供了一种易于处理的解决方法,在不限制风险规避参数的情况下,对投资组合约束(如有限的股票市场参与、保证金要求和卖空禁令)的资产定价影响产生了新的见解。我们证明,在一个投资者不受约束,而另一个投资者面临可投资于股票的财富比例的上限约束的情况下,该模型产生了逆周期市场价格的风险和股票回报波动,顺周期价格股息比,超额波动和其他与实证结果一致的模式。在有保证金要求的情况下,我们证明了在合理的参数下,更严格的约束可能会在约束可能生效的时候降低股票收益波动。

Financial Buyers vs. Strategic Buyers 金融买家vs.战略买家
Pub Date : 2013-03-23 DOI: 10.2139/ssrn.1725031
Marc Martos-Vila, Matthew Rhodes-Kropf, J. Harford
Within the great oscillations of overall merger activity there is a shifting pattern of activity between strategic (operating firms) and financial (private equity) acquirers. What are the economic factors that drive either financial or strategic buyers to dominant positions in M&A activity? We introduce debt market misvaluation in M&A activity. Debt misvaluation might seem limited since both types of acquirer (and the target) can access misvalued debt markets. However, moral hazard and insurance effect differences between types of buyers interact with potential debt misvaluation debt, leading to a dominance of financial versus strategic buyers that depends on debt market conditions.
在整体并购活动的巨大波动中,战略(运营公司)和金融(私募股权)收购方之间的活动模式发生了变化。是什么经济因素促使财务或战略买家在并购活动中占据主导地位?我们在并购活动中引入了债务市场的错误估值。债务估值错估似乎是有限的,因为两种类型的收购方(和目标方)都可以进入估值错估的债务市场。然而,不同类型买家之间的道德风险和保险效应差异与潜在的债务错误估值债务相互作用,导致金融买家与战略买家的主导地位,这取决于债务市场条件。
