Intermarket efficiency: An application of interbattery APT to mortgage-backed securities

Increasing popularity of investments in mortgage-backed securities has led to closer integration of the mortgage market into traditional capital markets. Using monthly returns during 1982–1988 for common stocks, Treasury bonds and GNMA and FHLMC mortgage-backed securities, the interbattery factor analytic Arbitrage Pricing Theory of (Cho, 1984) is used to test five hypotheses for intramarket and intermarket integration. Results indicate that three to five common factors are found within the same security market, while only one to three factors are found common between different markets.The APT could not be rejected within the same security market, but was rejected in most intermarket comparisons. While risk-free rates are found to differ between markets, the risk premium tests are conclusive indicators of integration. Our results support claims that the stock, bond, and the mortgage-backed securities markets are integrated.     

Analyst Earnings Forecast Revisions and the Pricing of Accruals

We investigate the relation between two market anomalies to provide insights into analysts role as information intermediaries. Prior research finds that accruals and analyst earnings forecast revisions predict future returns. We find that the accrual and forecast revision strategies generate hedge returns of 15.5% and 5.5% when implemented independently. Strikingly, a combined strategy that uses forecast revisions to refine the accrual strategy generates a hedge return of 28.5%. Firms with consistent accrual and forecast revision signals have less persistent accruals and earnings. We also find that accruals can be used to refine the forecast revision strategy—high accruals are associated with overoptimism in analyst forecasts. Our findings indicate that although forecast revisions reflect information about accrual and earnings persistence beyond that reflected in the level of current year accruals, investors do not fully incorporate this information into their valuation assessments.     

上市公司信息披露质量与证券分析师盈利预测

本文研究了上市公司信息披露状况与分析师预测行为之间的关系，结果发现，分析师的预测准确性总体上显著优于随机游走模型。进一步的研究发现，上市公司信息披露状况会对证券分析师的预测特征产生影响，信息披露透明度越高，分析师预测对会计盈利数据的依赖程度越低，预测准确性也随之提高。     

Failure to learn from failure: The 2008 mortgage crisis as a déjà vu of the mortgage meltdown of 1994

This article traces the developments in the market for residential mortgage-backed securities (MBS) during the period 1970–2008. Drawing on an analysis of trade publications, business press, and interviews with practitioners, it shows that an MBS market meltdown in 1994 provided clear signals of problems with MBS. The market participants did not re-evaluate their use of risk management tools or adjust security design in response to the 1994 crisis, suggesting a lack of understanding of the implications of the crisis. The 1994 meltdown showed that MBS were vulnerable to systematic risks and that these risks could precipitate an MBS market crash. Furthermore, the 1994 meltdown demonstrated that large-scale investment in MBS could affect the primary mortgage market, thereby rendering the MBS risks unpredictable. After 1994, MBS investment shifted to MBS backed by mortgages with default risk – a development that led to the crash of 2008. By drawing parallels between the 1994 and 2008 crises, this article shows how the MBS market failed to self-correct. The results suggest that financial market participants do not always incorporate relevant information in their decision-making and that market participants have difficulties in both foreseeing the effect of financial innovations on markets and interpreting these effects.     

价值溢价与一月效应——来自上海A股市场的经验证据

以2000年1月至2011年12月沪市A股上市公司为样本,按Size-B/M方法构建6投资组合,考察我国股市的价值溢价是否存在一月效应现象,检验大盘股、小盘股价值溢价在1月和非1月是否不同,并采用CAPM模型检验价值溢价的一月效应。实证结果发现:1)采用账面市值比B/M划分成长-价值型股票组合,大盘股和小盘股股票都存在价值溢价;2)大盘股和小盘股的价值溢价在1月与非1月存在不同的模式——大盘股在1月存在显著的价值溢价,而小盘股的价值溢价主要在非1月的月份出现;3)CAPM模型能够解释我国股市从2007年1月至2011年12月期间的价值溢价。相对小盘股,大盘股的价值溢价的一月效应更为显著。
