On the Nature and Predictability of Corporate Bond Returns 论公司债券收益的性质和可预测性
Pub Date : 2012-05-16 DOI: 10.2139/ssrn.1914680
Daniel Haesen, P. Houweling
Corporate bond returns consist of two distinct components: an interest rate component, which is default-free and anti-cyclical, and a credit spread component, which is default-risky and pro-cyclical. These components are mutually negatively correlated and their relative importance varies with credit quality. We show that it is of critical importance to take this into account when studying the predictability of corporate bond returns. In this paper we focus on the credit spread component of corporate bond returns, enabling us to find new predictors that were previously unknown to the literature. Moreover, by re-examining previously documented predictors, we are able to dismiss several of them as irrelevant for credit spread returns and to explain inconsistent findings between investment grade and high yield corporate bonds. In total, we find four factors with significant in-sample and out-of-sample predictability of both investment grade and high yield excess returns over Treasury. Two variables come from the existing literature: past equity return and past corporate bond return. Evidence for the other two variables is new: change in implied equity volatility and the Halloween indicator.
公司债券回报由两个不同的部分组成:利率部分,无违约且反周期;信用利差部分,有违约风险且顺周期。这些组成部分相互负相关,其相对重要性随信贷质量而变化。我们表明,在研究公司债券回报的可预测性时,考虑到这一点至关重要。在本文中,我们将重点放在公司债券回报的信用利差组成部分,使我们能够找到以前文献中未知的新预测因子。此外,通过重新检查先前记录的预测指标,我们能够排除其中一些与信贷利差回报无关的预测指标,并解释投资级和高收益公司债券之间不一致的发现。总的来说,我们发现四个因素对投资等级和高收益超额回报都具有显著的样本内和样本外可预测性。两个变量来自现有文献:过去的股票回报和过去的公司债券回报。另外两个变量的证据是新的:隐含股票波动率的变化和万圣节指标。

The Seasonality of Gold - The Autumn Effect 黄金的季节性——秋季效应
Pub Date : 2012-05-13 DOI: 10.2139/ssrn.1989593
D. Baur
This paper studies recurring annual events potentially introducing seasonality into gold prices. We analyze gold returns for each month from 1980 to 2010 and find that September and November are the only months with positive and statistically significant gold price changes. This “autumn effect” holds unconditionally and conditional on several risk factors. We argue that the anomaly can be explained with hedging demand by investors in anticipation of the “Halloween effect” in the stock market, wedding season gold jewelery demand in India and negative investor sentiment due to shorter daylight time. The autumn effect can also be characterized by a higher unconditional and conditional volatility than in other seasons.
本文研究了可能引入黄金价格季节性的经常性年度事件。我们分析了1980年至2010年每个月的黄金收益,发现9月和11月是唯一一个黄金价格正且具有统计显著变化的月份。这种“秋季效应”无条件地存在于几个风险因素中。我们认为,这种异常现象可以用投资者对股市“万圣节效应”的预期而产生的对冲需求、印度婚礼季黄金珠宝的需求以及白昼时间缩短导致的负面投资者情绪来解释。与其他季节相比,秋季效应还可以表现为更高的无条件和条件波动。

Assessing Time-Series Versus Cross-Sectional Influences in Panel Estimates: International Financial Architecture and Expected Equity Premia 评估小组估计中的时间序列与横断面影响:国际金融架构和预期股权溢价
Pub Date : 2012-04-29 DOI: 10.2139/ssrn.2047724
R. Aggarwal, John W. Goodell
In the study of economic and financial panel data it is often important to differentiate between time-series and cross-sectional effects. We present two estimation procedures that can do so and illustrate their application by examining international variations in expected equity premia and financial architecture where a number of variables vary across time but not cross-sectionally while other variables vary cross-sectionally but not across time. Using two different estimation procedures we find a preference for market financing to be negatively associated with the size of expected premia. However, we also find that U.S. corporate bond spreads negatively determine financial architecture according to the first procedure but not according to the second estimation as U.S. Corporate bond spreads change value each year but have the same value across countries. Similarly some measures that change across countries but do not change across time, such as cultural dimensions as well as the an index of measures against self dealing, are significant determinants of financial architecture according second estimation but not according to the first estimation. Our results show that using these two estimation procedures together can assess time-series versus cross-sectional variations in panel data. This research should be of considerable interest to empirical researchers.
在经济和金融面板数据的研究中,区分时间序列效应和横截面效应往往是很重要的。我们提出了两种可以做到这一点的估计程序,并通过检查预期股权溢价和金融架构的国际变化来说明它们的应用,其中许多变量随时间而变化,但不是横截面,而其他变量随时间而变化,但不是横截面。使用两种不同的估计程序,我们发现对市场融资的偏好与预期溢价的大小负相关。然而,我们也发现,根据第一种方法,美国公司债券利差负向决定了金融架构,而根据第二种方法,则不是,因为美国公司债券利差每年都在变化,但在不同的国家具有相同的值。同样,一些在不同国家发生变化但不随时间变化的指标,如文化维度以及防止自我交易的措施指数,根据第二次估计是金融架构的重要决定因素,但根据第一次估计则不是。我们的研究结果表明,使用这两种估计程序一起可以评估面板数据的时间序列与横截面变化。这一研究应该引起实证研究者的极大兴趣。

Price Discovery in Futures and Options Markets 期货和期权市场的价格发现
Pub Date : 2012-03-23 DOI: 10.2139/ssrn.2028002
Naomi E. Boyd, Peter R. Locke
We evaluate price discovery in the natural gas futures and futures options markets using a transaction‐based approach. By sampling market maker prices, we allow for a distinction between market maker buy and sell futures prices, both directly from trades in the futures market, and futures prices implied by trades in the options market. Information shares are compared between futures and options markets as well as within the options market. Given the common architecture of the two markets, as expected we find little price information generated in the options market. Within the options market, the highly levered out‐of‐the‐money options offer less price discovery than other options. We attribute this to the higher transaction costs of out‐of‐the‐money options. © 2013 Wiley Periodicals, Inc. Jrl Fut Mark 34:853–867, 2014
我们使用基于交易的方法评估天然气期货和期货期权市场的价格发现。通过抽样做市商的价格,我们可以区分做市商买卖期货的价格,这两种价格都是直接来自期货市场的交易,以及期权市场交易隐含的期货价格。信息共享在期货和期权市场之间以及期权市场内部进行比较。鉴于两个市场的共同架构,正如预期的那样,我们发现期权市场中产生的价格信息很少。在期权市场中,高杠杆的场外期权比其他期权提供更少的价格发现。我们将此归因于价外期权较高的交易成本。©2013 Wiley期刊公司[j] .中国科学:自然科学,2014

What Explains the Distress Risk Puzzle: Death or Glory? 如何解释痛苦风险之谜:死亡还是荣耀?
Pub Date : 2012-03-15 DOI: 10.2139/ssrn.2023933
Jennifer S. Conrad, Nishad Kapadia, Yuhang Xing
Campbell, Hilscher, and Szilagyi (2008) show that firms with a high probability of default have significantly low average future returns. We show that there is a large overlap between stocks classified as high default risk, and those that are likely to produce extremely high returns over the next year (‘glory’ stocks). Predicted glory and predicted distress are highly correlated, with over 50% of firms in the top distress risk quintile also in the top quintile of predicted glory. Stocks with high predicted probabilities for glory also earn abnormally low average returns. We find evidence that low returns to high glory firms are also present in firms with zero leverage, where financial distress is unlikely, and that the low returns to high distress risk firms are large and significant in ‘speculative’ firms (with high sales growth and market-to-book ratios) that have high predicted glory; subsequent returns are small and statistically insignificant in ‘traditionally distressed’ firms. Thus, we show that, on average, firms which have a high potential for death (default) also tend to have a high potential for glory; where the two factors can be separated, the results suggest that it is glory, rather than distress, which is responsible for the low expected returns in securities.
Campbell, Hilscher, and Szilagyi(2008)表明,违约概率高的企业的平均未来收益显著较低。我们发现,在被归类为高违约风险的股票和那些可能在明年产生极高回报的股票(“荣耀”股票)之间存在很大的重叠。预测的荣耀和预测的痛苦高度相关,超过50%的公司处于困境风险最高的五分之一,同时也处于预测荣耀的最高五分之一。那些被预测很有可能获得辉煌的股票,其平均回报率也异常低。我们发现证据表明,高荣耀公司的低回报也存在于零杠杆的公司中,这些公司不太可能出现财务困境,而高困境风险公司的低回报在具有高预期荣耀的“投机性”公司(具有高销售增长和市净率)中是巨大而显著的;在“传统上陷入困境”的公司中,随后的回报很小,在统计上也不显著。因此,我们表明,平均而言,具有高死亡(违约)潜力的公司也往往具有高荣耀潜力;如果这两个因素可以分开,结果表明,是荣耀,而不是痛苦,导致了证券的低预期回报。

Social Interaction Effects and Individual Portfolio Choice: Evidence from 401(K) Pension Plan Investors 社会互动效应与个人投资组合选择:来自401(K)养老金计划投资者的证据
Pub Date : 2012-03-15 DOI: 10.2139/ssrn.2024095
Timothy (Jun) Lu, Ning Tang
We show that participants are influenced by their coworkers when they make equity investment decisions. Using a rich dataset of 401(k) plans, we find that individuals are likely to increase (decrease) their risky share when they have lower (higher) equity exposure than their coworkers in the last period. The effect is especially strong when the difference in equity exposure is substantial. Furthermore, individuals are likely to increase their equity exposure if they earn lower equity returns than their coworkers did in the last period. However, when their returns on equity are higher than their peers’, they tend not to decrease their risky share. The interaction of peer behavior and peer outcome influences investment decisions, inducing individuals with substantially lower equity exposure than their coworkers to increase their risky share when coworkers also earned higher returns. Finally, we find that there exists heterogeneity in short-term excess returns following social interaction.
我们表明,参与者在做出股权投资决策时受到同事的影响。利用401(k)计划的丰富数据集,我们发现,当个人在上一时期的股票敞口比同事低(高)时,他们可能会增加(减少)他们的风险份额。当股票敞口的差异很大时,这种影响尤其强烈。此外,如果个人在过去一段时间内获得的股票回报低于同事,他们可能会增加股票敞口。然而,当他们的股本回报率高于同行时,他们往往不会降低风险份额。同伴行为和同伴结果的相互作用影响投资决策,诱导那些比同事的股票风险敞口低得多的个人在同事也获得更高回报的情况下增加风险份额。最后,我们发现社会互动后的短期超额收益存在异质性。

Strategic Credit Line Usage and Performance 战略信用额度的使用和表现
Pub Date : 2012-03-15 DOI: 10.2139/ssrn.2023788
A. Kizilaslan, A. Mathers
This paper uses a unique dataset of corporate credit line usage to examine whether firms draw precautionary balances from their credit lines in anticipation of a decline in future availability. We find that credit line drawdowns precede declines in cash flow. Further, we model predicted drawdowns and estimate unexpected drawdowns as the residual from the predictive regression. We show that unexpected drawdowns predict future cash flow declines, future covenant violations and concurrent ratings downgrades. Consistent with the use of unexpected drawdowns as a proxy for precautionary balances that are not needed for immediate investment, unexpected drawdowns are associated with increases in cash balances. Firms with unexpected drawdowns do not get better terms in renegotiations, but they are more able to finance future capital expenditures following a covenant violation than those firms without unexpected drawdowns. Overall, these findings support the hypothesis that firms strategically draw on their credit lines to access cash before their performance deteriorates.
本文使用一个独特的企业信用额度使用数据集来检验企业是否在预期未来可用性下降的情况下从其信用额度中提取预防性余额。我们发现,信贷额度的下降先于现金流的下降。此外,我们对预测的下降进行建模,并估计意外的下降作为预测回归的残差。我们表明,意外提款预测未来现金流下降、未来契约违约和同时评级下调。与使用意外提款作为不需要立即投资的预防性余额的代表相一致的是,意外提款与现金余额的增加有关。在重新谈判中,意外撤资的公司不会得到更好的条款,但它们比那些没有意外撤资的公司更有能力为违反契约后的未来资本支出提供资金。总的来说,这些发现支持了公司在业绩恶化之前战略性地利用其信贷额度来获取现金的假设。

Friendly Takeover Offers for Public Corporations: Interim Uncertainty, Reserve Prices, and Bustup Fees 上市公司的友好收购要约:中期不确定性、保留价格和破产费
Pub Date : 2012-03-15 DOI: 10.2139/ssrn.2023946
Bernard Black, R. Dam
Legal restrictions create a material delay between the announcement of a friendly acquisition of a public firm and the deal’s final approval by target shareholders: a month for a takeover with a first step cash tender offer, longer for a merger. During this time target values may change, perhaps dramatically. While a target can accept new bids if its value rises, bidders usually cannot back out if the target’s value falls. We also observe that most takeovers occur at a significant premium to the target’s prior market price. Prior models of takeover bidding ignore the law-induced delay and resulting asymmetry between bidder and target, and generally assume that targets (if for sale) will accept zero-premium offers. We develop a model that incorporates delay-induced asymmetry and reserve prices. Principal new predictions include: targets often optimally set reserve prices higher than the current market price; first bidders may value the target for more than the target’s reserve price, yet be unwilling to bid because they expect a loss after accounting for the implied put option they provide the seller; the likelihood of a bidder making a bid is generally decreasing in the reserve price, the interim uncertainty, and the number of potential competing bidders; optimal reserve prices are decreasing in the interim uncertainty and number of potential new bidders, and can be below the target’s current price in extreme cases; (if the target offers a bustup fee to the first bidder, this increases the (conditional on the bustup fee) optimal reserve price, but reduces the target’s expected profit. Our predictions on the effect of bustup fees provide theoretical support for legal limits on bustup fees and other deal protections.
法律上的限制造成了从宣布友好收购上市公司到目标股东最终批准交易之间的实质性延迟:第一步现金收购要约的收购需要一个月,合并需要更长时间。在此期间,目标值可能会发生变化,可能会发生巨大变化。如果收购目标的价值上升,收购方可以接受新的出价,但如果收购目标的价值下跌,收购方通常无法退出。我们还观察到,大多数收购的价格都比目标公司之前的市场价格高出很多。先前的收购投标模型忽略了法律导致的延迟以及由此导致的投标人和目标之间的不对称,并且通常假设目标(如果出售)将接受零溢价报价。我们开发了一个包含延迟引起的不对称和储备价格的模型。主要的新预测包括:目标通常设定的最优底价高于当前市场价格;首先出价的人可能对目标的估价高于目标的保留价,但他们不愿意出价,因为他们预计在考虑了他们向卖方提供的隐含看跌期权后会蒙受损失;投标人出价的可能性在底价、中期不确定性和潜在竞争投标人的数量方面普遍下降;在过渡时期,不确定性和潜在新竞标者的数量在下降,在极端情况下可能低于目标的当前价格;(如果目标公司向第一个竞标者提供买断费,这会增加(以买断费为条件)最优保留价格,但会降低目标公司的预期利润。我们对破产费影响的预测为破产费的法律限制和其他交易保护提供了理论支持。

The Role of Bond Markets When Portfolio Choice is Constrained 投资组合选择受限时债券市场的作用
Pub Date : 2012-03-15 DOI: 10.2139/ssrn.2023630

We develop a two-country international asset pricing model in which some investors face leverage constraints. In contrast to models with a single `world' bond, we show that tightening regulation can lead to the risk free interest rate rising. When demand for borrowing is high, a tightening of the constraint causes the investor to shift his loans from international more into local bond markets, putting upwards pressure on local interest rates. Indeed, he sacrifices diversification to gain more risk exposure, by under diversifying currency risk through international bonds. Exchange rate dynamics give rise to a currency risk premium, making carry trades profitable - even in the benchmark unconstrained economy. Consistent with empirical findings, a sudden binding of constraints can significantly shift exchange rate dynamics, rendering previously set up carry trades unprofitable.
我们开发了一个两国国际资产定价模型,其中一些投资者面临杠杆约束。与单一“世界”债券的模型相比,我们表明,收紧监管可能导致无风险利率上升。当借款需求高涨时,约束的收紧会导致投资者将贷款从国际市场更多地转移到当地债券市场,从而给当地利率带来上行压力。事实上,他牺牲了多元化,通过国际债券来降低货币风险的多元化,从而获得更多的风险敞口。汇率动态会产生货币风险溢价,使套息交易有利可图——即使在基准不受约束的经济中也是如此。与实证研究结果一致,约束的突然绑定可以显著改变汇率动态,使先前设置的套利交易无利可图。

Short-Term Persistence in Hybrid Mutual Fund Performance: The Role of Style-Shifting Abilities 混合型共同基金业绩的短期持续性:风格转换能力的作用
Pub Date : 2012-03-12 DOI: 10.2139/ssrn.1856076

Our study analyzes the performance of hybrid mutual funds. Based on two extended Carhart models we determine total fund performance by comparing fund returns to investable fund-specific style benchmarks. Using daily returns and a quarterly measurement interval, we present an innovative return-based approach to decompose total performance into in-quarter abnormal performance and style-shifting performance. In addition, we split total style-shifting performance into active and passive components. In this context, we confirm possible benefits of these performance measures by analyzing several simulated investment strategies. Our empirical study covers 520 hybrid mutual funds from 10/1998 to 12/2009 and shows that hybrid mutual funds (i) do not outperform their benchmarks on average, (ii) partially show positive in-quarter abnormal performance and style-shifting abilities, and (iii) exhibit short-term persistence in in-quarter abnormal performance but not in style-shifting abilities.
我们的研究分析了混合共同基金的绩效。基于两个扩展的Carhart模型,我们通过将基金回报与可投资基金特定风格基准进行比较来确定基金的总体表现。利用日收益和季度度量区间,我们提出了一种基于收益的创新方法,将总绩效分解为季度异常绩效和风格转换绩效。此外,我们将总风格转换性能分为主动和被动组件。在这种情况下,我们通过分析几种模拟投资策略来确认这些绩效指标可能带来的好处。我们的实证研究涵盖了1998年10月至2009年12月期间的520只混合共同基金,结果表明混合共同基金(i)平均表现不优于基准,(ii)部分表现出积极的季度内异常表现和风格转换能力,以及(iii)在季度内异常表现中表现出短期持久性,但在风格转换能力方面没有表现出来。
