Media heterogeneity and post‐earnings announcement drift: evidence from China

This paper examines how the Chinese stock market acts differently towards state‐controlled and market‐oriented media coverage. Using a setting of post‐earnings announcement drift, we find that information from state‐controlled media enters the stock price in a timelier manner, while the message from market‐oriented media needs more time to get a response from investors. The effect is also influenced by whether the type of news coverage is good or bad. Our findings suggest that the capital market underreacts when good news is reported by the market‐oriented media.

The Optimal Timing of Open Market Stock Repurchases

Using a continuous-time real options approach we determine the conditions under which a value-maximizing company would conduct an open market stock repurchase to exploit the undervaluation of shares. We find the optimal timing of such repurchases as well as the optimal amount a company should repurchase and analyze how it depends on market parameters. Obtaining the announcement returns from the authorization of stock repurchases from our model allows us to derive testable empirical implications.     

投资风格漂移与基金业绩——来自开放式基金的经验证据

基金投资风格是双刃剑,带来短期超额收益同时也具有巨大漂移风险。目前我国基金信息披露制度不完善,相关监管缺失,加上投资者大多只注重收益而忽视风险,导致基金投资风格漂移现象普遍存在。选取2004年7月前成立的65只偏股型基金为样本,对样本基金在2005—2012年的实际投资风格进行识别,并检验基金业绩与风格漂移的关系,结果显示：基金存在严重的投资风格漂移现象,而且漂移随股市走势变化明显,基金整体上投资风格趋同;在价值/成长风格的漂移方面,大多数基金投资风格倾向于成长型或平衡型,价值型风格缺乏;在大/小盘风格的漂移方面,基金投资风格均匀分布于大盘和小盘,某些年份随股市走势变化,风格漂移明显且趋同;过去业绩越好的基金越容易发生投资风格漂移,且投资风格漂移并不能带来基金业绩的改善。     

Explanatory factors of the inflation news impact on stock returns by sector: The Spanish case

We study the short run response of daily stock prices on the Spanish market to the announcements of inflation news at an industrial level, deepening the potential explanatory factors of this response (risk-free interest rate, risk premium and growth expectations). We observe a positive and significant response of the stock returns in case of “bad news” (total inflation rate higher than expected one) in recession, and also in case of negative inflation surprises (“good news”) in non-economic recession. This behaviour is consistent with the evolution of the company dividend growth expectations, since we observe that the relationship between this theoretical component of the stock price and the unexpected inflation, to a large extent, seems to explain the observed behaviour.     

微型金融机构使命漂移的实证分析--基于对湖北省恩施土家族苗族自治州的调研数据

本文利用SPSS17.0分析软件对恩施土家族苗族自治州的198份样本数据进行统计学分析和回归分析的结果表明,我国的微型金融机构（MFIs）出现了使命漂移的趋势。但MFIs使命漂移既有MFIs“利润驱动”的因素,也有贫困农户“主动放弃”和贷款给农户带来累积正面效应的因素。     

Comment on ‘earnings management around UK open offers’

This note discusses the result of Iqbal, A., S. Espenlaub, and N. Strong. 2008 Iqbal, A., Espenlaub, S. and Strong, N. 2008. Earnings management around UK open offers. European Journal of Finance, this issue [Google Scholar]. Earnings management around UK open offers. European Journal of Finance, this issue, regarding long-run abnormal returns following open offers and announcement abnormal returns, compared with differing results in two previous studies based on similar samples. A survivorship bias explains some of the differences in the reported long-run abnormal returns. The difference in the announcement abnormal returns could be due to use of different data sources.     

Empirical of the Taiwan stock index option price forecasting model – applied artificial neural network

This work presents a novel neural network model for forecasting option prices using past volatilities and other options market factors. Out of different approaches to estimating volatility in the option pricing model, this study uses backpropagation neural network to forecast prices for Taiwanese stock index options. The ability to develop accurate forecasts of grey prediction volatility enables practitioners to establish an appropriate hedging strategy at in-the-money option.
