Liquidity,Skewness and Stock Returns: Evidence from Chinese Stock Market

In this paper, a capital asset pricing model (CAPM) incorporating liquidity and skewness factors is proposed and tested by using the Chinese stock market data. The empirical results indicate that, under various market conditions, the liquidity-adjusted three-moment CAPM provides a better fit to the realized returns of various stock portfolios. Overall, this research reveals that illiquidity cost, liquidity risk and as well as skewness have important impacts on asset pricing in the Chinese stock market.     

Earnings Yields,Market Values,and Stock Returns

Earlier evidence concerning the relation between stock returns and the effects of size and earnings to price ratio (E/P) is not clear-cut. This paper re-examines these two effects with (a) a substantially longer sample period, 1951–1986, (b) data that are reasonably free of survivor biases, (c) both portfolio and seemingly unrelated regression tests, and (d) an emphasis on the important differences between January and other months. Over the entire period, the earnings yield effect is significant in both January and the other eleven months. Conversely, the size effect is significantly negative only in January. We also find evidence of consistently high returns for firms of all sizes with negative earnings.     

The Weekly Pattern in Stock Returns: Cash versus Futures: A Note

This paper presents tests designed to determine whether the weekly pattern in stock returns continues after the introduction of futures trading on stock indexes and whether the pattern carries over to the futures market. Using data for the SP500, I find that the “Monday effect” does persist in the cash market, but there is no evidence of a similar pattern in the futures market.     

2011银行间市场资金面透析与预判

2011年年初以来,国内银行间市场资金面波动幅度较大,总体上经过了一个紧缩、略微宽松、再次紧缩的过程。从反映资金紧张状况的市场资金利率指标看,年初的时候,上海银行间同业拆借利率3个月SHIBOR为4.52%,7天回购利率(FR007)为3.26%,1天回购利率(FR001)为2.7%,均处于较为适中水平。但是,在春节前后,受数次提高法定准备金率累积效应和机构紧缩预期影响,市场资金利率攀升至多年少见的高位,2月初,3个月SHIBOR高达5.7%,7天和1     

Stock Market Returns and Economic Fundamentals in an Emerging Market: The Case of Korea

This paper investigates the feedback relationship between stock market returnsand economic fundamentals in an emerging market. Starting from an intertemporalconsumption-based CAPM (CCAPM), we obtain a restricted VAR model for stockreturns and macroeconomic variables. We then apply this model to Korea and findstatistically significant departures from the restrictions implied by CCAPM.Consequently, an unrestricted VAR model is used to analyze the variations of expectedand unexpected returns in the Korean stock market. It is shown that the expectedmarket returns vary with a set of macroeconomic variables, and that thepredictable component is substantial. Reflecting richer dynamics in the data,relative to the usual single equation modeling in the literature, the estimatedVAR model shows considerable predictive ability for both real economic activityand real returns. Using the model for a variance decomposition of unexpectedreturns, we find that, although we cannot directly observe the market's revisionof expected future dividend growth, we can estimate a large part of therevision with the news in the expected industry output growth from our VAR model.Finally, we also find that economic fundamentals can explain only a smallportion of the variation in unexpected returns in the Korean stock market.     

成交量和回报率对信息扰动的市场反应研究——以中国A股市场为例

用BVAR和BMAR模型及脉冲—响应分析方法来考察中国股票市场上成交量和回报率对信息扰动的动态反应情况得出,公共扰动和永久性扰动是回报率的主要决定因素,而非公共扰动和暂时性扰动则是成交量的主要决定因素。但是公共扰动和永久性扰动对成交量有明显影响;非公共扰动和暂时性扰动对回报率有明显影响。     

投资者分歧、异常交易量和股票横截面收益率预测——基于中国股票市场的经验证据

本文定义月度异常交易量为本月与上个月交易金额的比值,发现中国市场月度收益率与滞后一个月的异常交易量显著负相关。在控制了公司规模、账面市值比、流动性以及动量效应等指标后仍然具有显著的解释作用。进一步研究表明,在出现高异常交易量后的12个月内,换手率和特质性波动率都有大幅上升。本文认为,交易量上升代表着市场分歧程度和受关注程度的增加,在卖空约束下会使得股票价值高估,从而造成未来收益率下降。     

Stock Market Returns and Inflation: Evidence from Other Countries

This paper investigates the relation between common stock returns and inflation in twenty-six countries for the postwar period. Our results do not support the Fisher Hypothesis, which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one-to-one correspondence with expected inflation. There is a consistent lack of positive relation between stock returns and inflation in most of the countries.     

Framing Effects in Stock Market Forecasts: The Difference Between Asking for Prices and Asking for Returns

Studies analyzing return expectations of financial market participantslike fund managers, CFOs or individual investors are highlyinfluential in academia and practice. We argue and show thatthe results in these surveys above are easily influenced bythe elicitation mode of return expectations. Surveys that askfor future stock price levels are more likely to produce meanreverting expectations than surveys that directly ask for futurereturns. Furthermore, we conduct a questionnaire study thatexplicitly analyzes whether the specific elicitation mode affectsreturn expectations in the above direction. In our study, subjectswere asked to state mean forecasts for seven time series. Usinga between subject design, one half of the subjects was askedto state future price levels, the other group was directly askedfor returns. We observe a highly significant framing effect.For upward sloping time series, the return forecasts statedby investors in the return forecast mode are significantly higherthan those derived for investors in the price forecast mode.For downward sloping time series, the return forecasts givenby investors in the return forecast mode are significantly lowerthan those derived for investors in the price forecast mode.We argue that this finding is consistent with behavioral theoriesof investor expectation formation based on the representativenessheuristic.     

中国股票市场关于股票收益的两个假设的检验

使用方差比方法检验中国股票市场上股票收益服从随机游走的假设,检验结果拒绝了该假设。而使用Geweke和Porter—Hudak(1983)提出的分数差分检验,检验结果却支持股票收益存在长期记忆的假设。长期记忆性的存在使得有可能通过建立非线性经济计量模型以改进价格预测效果。     

The Cross-Section of Expected Stock Returns: New Evidence from an Emerging Market

Over 300 factors have been found to explain the cross-section of expected stock returns. Empirical studies also show that findings from multifactor asset-pricing models have not been consistent in an emerging market. Using DuPont analysis and a residual income valuation model for 284 nonfinancial companies on Ho Chi Minh Stock Exchange during the period 2008–2014, findings suggest that the return on equity and its change are informative for stock returns in Vietnam. In addition, the level of capital turnover, financial cost ratio (FCR), and changes in capital and in the FCR contain incremental explanatory power for stock returns.     

The Diversification Discount: Cash Flows Versus Returns

Diversified firms have different values from comparable portfolios of single-segment firms. These value differences must be due to differences in either future cash flows or future returns. Expected security returns on diversified firms vary systematically with relative value. Discount firms have significantly higher subsequent returns than premium firms. Slightly more than half of the cross-sectional variation in excess values is due to variation in expected future cash flows, with the remainder due to variation in expected future returns and to covariation between cash flows and returns.     

Using Nonnormal Distributions to Analyze the Relationship Between Stock Returns in Japan and the US

The Pearson distribution system is researched and applied to financial engineering (Nagahara, Financ Eng Jpn Mark 2(2):139–154 in 1995, Financ Eng Jpn Mark 3(2):121–149 in 1996, Stat Prob Lett 43:251–264 in 1999, J Time Ser Anal 24(6):721–738 in 2003, A method of fitting multivariate nonnormal distributions to financial data. Discussion paper of Institute of Social Sciences, F-2006-2, Meiji University in 2006, Asia Pac Financial Markets 15(3–4):175–184 in 2008a). And a method of fitting multivariate nonnormal distributions by using random numbers from the Pearson distribution system was developed (Nagahara, Comput Stat Data Anal 47(1):1–29 in 2004). This method uses the grid search of the parameters for the maximum likelihood. In this paper, we adopt Grid-Computing and its middleware for the parameter sweep in order to reduce the computational time and the workload of this method. In the area of the financial risk management, it is very important to analyze the relationship between stock returns in Japan and the US. We analyze the data based on the same date and the following date because Japanese stock market opens before the US stock market opens in a day. We compare these returns by means of the multivariate nonnormal distributions by using this method. And we test the international transmission of stock markets movement. Furthermore, we obtain the optimal job schedule for our computer system using the middleware in order to reduce the computational time.     

Book–to–Market Equity, Distress Risk, and Stock Returns

This paper examines the relationship between book–to–market equity, distress risk, and stock returns. Among firms with the highest distress risk as proxied by Ohlson's (1980) O–score, the difference in returns between high and low book–to–market securities is more than twice as large as that in other firms. This large return differential cannot be explained by the three–factor model or by differences in economic fundamentals. Consistent with mispricing arguments, firms with high distress risk exhibit the largest return reversals around earnings announcements, and the book–to–market effect is largest in small firms with low analyst coverage.     

新上市股票异常报酬与经营绩效研究

以1994年到1999年深、沪两市的新上市A股为样本，采用单(配对)样本t-检验、非参数的Wilcoxon配对符秩检验等研究方法，研究了新上市公司股价的异常报酬和财务绩效的关系。研究结果表明新上市公司的股价有短期正异常报酬，而且上市后当年财务经营绩效比上市前要差，上市后第二年财务经营绩效更差。
