We investigate how investor overconfidence and attention affect market efficiency around the 2015 Chinese stock market crash. We find that the price delay before the crash is about twice the price delay after the crash. Investors become more sensitive to market movements after the crash. Price delays are larger on market down‐days than on up‐days before the crash, but the differences are insignificant between up‐ and down‐days after the crash, indicating that negative information travels slowly only when investors are overconfident. Margin traders follow market trends and intensify the pyramiding and de‐pyramiding effects caused by market sentiment change.
本文研究了2015年中国股市崩盘前后投资者过度自信和关注对市场效率的影响。我们发现,崩盘前的价格延迟大约是崩盘后价格延迟的两倍。股市崩盘后,投资者对市场走势变得更加敏感。价格延迟在崩盘前的市场下跌日比上涨日更大,但在崩盘后的上涨日和下跌日之间的差异微不足道,这表明只有当投资者过度自信时,负面信息才会传播缓慢。融资融券交易者跟随市场趋势,加剧市场情绪变化引起的金字塔效应和去金字塔效应。

The Effect of 52 Week Highs and Lows on Analyst Stock Recommendations 52周高点和低点对分析师股票推荐的影响
Pub Date : 2018-11-01 DOI: 10.1111/acfi.12312
Mei-Chen Lin
In this study, I examine whether analysts use the 52 week high and low as reference prices for recommendation revisions. My results show that the proximity and recency of the 52 week high increase the odds of stocks being upgraded. When analysts upgrade a stock whose 52 week high occurred in the distant past, they provide more valuable information to investors than that based on the proximity ratio of the 52 week high. More‐experienced analysts provide more valuable recommendations when they upgrade (downgrade) based on either the nearness or recency of the 52 week high (low) than less‐experienced analysts do.
在本研究中,我考察了分析师是否使用52周的最高价和最低价作为建议修订的参考价格。我的研究结果显示,接近52周高点的时间和时间增加了股票被升级的几率。当分析师升级一只52周高点发生在遥远过去的股票时,他们向投资者提供的信息比基于52周高点的接近率的信息更有价值。与经验不足的分析师相比,经验丰富的分析师在基于52周高点(低点)的接近度或近期进行升级(降级)时,会提供更有价值的建议。

Margin Trading and Price Efficiency: Information Content or Price‐Adjustment Speed? 融资融券交易与价格效率:信息量还是调价速度?
Pub Date : 2018-09-09 DOI: 10.1111/acfi.12403
Dayong Lv, Wenfeng Wu
The literature offers contradictory views on the effect of margin‐trading activities on price efficiency. Based on data from a Chinese margin‐trading pilot programme in 2010, we separate price efficiency into information content and price‐adjustment speed and investigate the effect of margin‐trading activity on price efficiency. We find that after adding to the eligible list, pilot stocks experience a decrease in information content, but an increase in price‐adjustment speed. Furthermore, increased margin‐buying activities are associated with lower information content, but faster price adjustment. Our results reconcile the debate over the effect of margin trading on price efficiency.
关于保证金交易活动对价格效率的影响,文献提供了相互矛盾的观点。基于2010年中国保证金交易试点项目的数据,我们将价格效率分为信息内容和价格调整速度,并研究了保证金交易活动对价格效率的影响。我们发现,加入合格名单后,试点股票的信息含量下降,但价格调整速度加快。此外,增加的保证金购买活动与较低的信息含量有关,但价格调整更快。我们的研究结果调和了保证金交易对价格效率影响的争论。

The Sensitivity of the Credit Default Swap Market to Financial Analysts’ Forecast Revisions 信用违约互换市场对金融分析师预测修正的敏感性
Pub Date : 2018-09-01 DOI: 10.1111/acfi.12235
Pervaiz Alam, Xiaoling Pu, Barry Hettler
We examine the impact of analysts’ earnings per share (EPS) and cash flow per share (CPS) forecast revisions on the market for credit default swaps. We find that while the issuance of both EPS and CPS forecast revisions are inversely associated with changes in credit default swap (CDS) spreads, cash flow forecast revisions have a larger effect. We demonstrate that the relationship between CPS forecast revisions and CDS spreads tends to be stronger in cases of financial distress. We provide evidence that cash flow forecasts dominate earnings forecasts in some situations and that participants in the CDS market discriminate between analysts' forecast revisions and recommendation changes.
我们研究了分析师的每股收益(EPS)和每股现金流量(CPS)预测修正对信用违约掉期市场的影响。我们发现,虽然EPS和CPS预测修正的发行与信用违约互换(CDS)价差的变化呈负相关,但现金流量预测修正的影响更大。我们证明,在财务困境的情况下,CPS预测修正和CDS价差之间的关系往往更强。我们提供的证据表明,现金流量预测在某些情况下主导盈利预测,CDS市场的参与者会区分分析师的预测修正和建议变化。

Deleveraging and Decline in Revenue‐Expense Matching Over Time 随着时间的推移,去杠杆化和收入-费用匹配的下降
Pub Date : 2018-08-01 DOI: 10.1111/jbfa.12343
Jeong‐Hoon Hyun, Hyungjin Cho
Accounting rules mandate that the cost of debt should be recorded as an expense, while the cost of equity does not appear in the income statement. Therefore, the amount of financing expense, and thus net income, in the income statements depends on how firms finance their business. Based on a clear, substantial trend of declining leverage since the 1990s, we examine how changes in capital structure might influence earnings attributes—the matching between revenues and expenses. We find that the contemporaneous relation between revenues and interest expense in US firms has decreased from 1972 to 2013, a result of both changes in leverage and the declining explanatory power of interest expense with respect to revenues. When we construct the weighted average costs of capital based on the costs of both debt and equity, we find the contemporaneous relation between revenues and the costs of capital has not significantly changed. Our results indicate that differential accounting treatment of the costs of debt and equity can affect earnings attributes through change in capital structure.
会计准则规定债务成本应记为费用,而权益成本不应出现在损益表中。因此,损益表中融资费用的数额,以及由此产生的净收入,取决于企业如何为其业务融资。基于自20世纪90年代以来杠杆率明显下降的趋势,我们研究了资本结构的变化如何影响收益属性—收入和支出之间的匹配。我们发现,从1972年到2013年,美国公司收入和利息支出之间的同期关系有所下降,这是杠杆率变化和利息支出相对于收入的解释力下降的结果。当我们在债务成本和股权成本的基础上构建加权平均资本成本时,我们发现收入与资本成本之间的同期关系并没有显著变化。我们的研究结果表明,债务成本和股权成本的差异会计处理可以通过资本结构的变化影响收益属性。

The Competitive Effects of S&P 500 Index Revisions 标准普尔500指数修正的竞争效应
Pub Date : 2018-07-01 DOI: 10.1111/jbfa.12312
Sheng-Syan Chen, Yueh-hsiang Lin
Firms added to the S&P 500 Index gain a competitive advantage over their non‐S&P 500 industry competitors. They experience positive stock valuation effects at the expense of competitors. The inclusion is associated with both reductions in financial constraints and the cost of equity and increases in capital investment for the newly added firms. When the increase in capital investment is greater, they gain more market share and enjoy better valuation effects. Rivals’ share price responses are negatively related to the announcement effect of the newly added firm. Deletions from the index, however, do not have symmetric effects.
加入标准普尔500指数的公司比其非标准普尔500指数的行业竞争者获得竞争优势。他们以牺牲竞争对手为代价,经历了积极的股票估值效应。这与新加入公司的财务限制和股权成本的减少以及资本投资的增加有关。资本投入增加越大,获得的市场份额越大,估值效果越好。竞争对手的股价反应与新公司的公告效应呈负相关。但是,从索引中删除不具有对称效果。

The Recent Financial Crisis, Start‐Up Financing and Survival 最近的金融危机,创业融资和生存
Pub Date : 2018-06-19 DOI: 10.1111/jbfa.12319
M. Deloof, T. Vanacker
We investigate the effects of the recent financial crisis on start‐up financing and survival using a dataset that covers all Belgian new business registrations between 2006 and 2009. We find that bank debt is the single most important source of funding, even for start‐ups founded during the crisis. However, start‐ups founded in crisis years use less bank debt and have a higher likelihood of bankruptcy, even after controlling for their creditworthiness. These effects are stronger for start‐ups that are more dependent on bank debt, such as start‐ups founded in bank dependent industries and start‐ups founded by entrepreneurs who are more likely to be financially constrained.
我们调查了最近的金融危机对初创企业融资和生存的影响,使用的数据集涵盖了2006年至2009年间比利时所有的新企业注册。我们发现银行债务是唯一最重要的资金来源,即使是在危机期间成立的初创企业也是如此。然而,在危机年份成立的初创企业使用较少的银行债务,即使在控制了其信誉之后,破产的可能性也更高。这些影响对于那些更依赖银行债务的初创企业更为明显,比如在依赖银行的行业成立的初创企业,以及由更有可能受到资金限制的企业家创办的初创企业。

A market†neutral strategy that is long [short] stocks with a high [low] Piotroski F†score generates an index†weighted 0.8 percent pm on S&P/ASX 200 stocks and 1.4 percent pm on smaller stocks. Equal†weighted returns are higher and in all cases returns are statistically significant. However, the Carhart model alphas are not statistically significant except in the case of equal†weighted small cap portfolios. For such portfolios, however, most of the alpha comes from the short side and most institutional investors would find them uninvestable due to capacity constraints. A range of tests indicate that analyst neglect does not explain the F†score premium.

Real Estate's Information and Volatility Links with Stock, Bond and Money Markets 房地产的信息和波动性与股票,债券和货币市场的联系
Pub Date : 2018-05-18 DOI: 10.1111/acfi.12375
Lin Mi, A. Hodgson
We examine real estate's information and volatility linkages with stock, bond and money markets. Based on the theory that the volatility of prices directly reflects of the rate at which information flows to the market (Kyle, ; Ross, ), we propose that information linkages across markets are revealed in the correlations of their volatilities, rather than correlations of returns. Applying an implied volatility correlation approach and the Generalized Method of Moments (GMM) estimation of Fleming et al. () stochastic volatility model, we find strong information and volatility linkages across the four markets.
我们研究了房地产的信息和波动性与股票、债券和货币市场的联系。基于价格波动的理论直接反映了信息流向市场的速度(凯尔,;罗斯,),我们提出,跨市场的信息联系是在其波动性的相关性中揭示的,而不是回报的相关性。应用隐含波动率相关方法和Fleming等人()随机波动率模型的广义矩量法(GMM)估计,我们发现四个市场之间存在很强的信息和波动率联系。
