Dynamic interaction of risk–return trade-offs between oil market and China’s stock market: An analysis from the risk preferences perspective

The risk–return trade-off refers to the compensation required by investors for bearing risks, which can be viewed as the risk preference of investors in a market. The current study investigates the dynamic interdependence of risk–return trade-offs between China’s stock market and the crude oil market from the perspective of risk preference of investors, which is designed to explore the transmission process of investors’ risk preference in both markets. Specifically, this study applies the time-varying parameter GARCH-M model, namely TVP-GARCH-M model, to characterize the time-dependent risk–return trade-offs (investors’ risk preferences) in the crude oil and China’s stock markets, then examines their relationship through Granger causality tests. Results show that a variation in risk preferences of the oil market investors can dramatically cause a variation in risk preferences of the Chinese stock market investors, while the risk preference of investors in the Chinese stock market does not lead to that in the crude oil market, which is in accordance with expectations. The dynamic effect of investors’ risk appetite in the crude oil market is further examined by the TVP-VAR model. The findings of this work suggest that there generally exists a positive impact of investors’ risk preference in the oil market and that the effect is time-varying to a greater degree during the short and medium term. Moreover, responses of the Chinese stock market investors’ risk preference were more significant during the 2008 financial crisis. Additionally, the empirical results remain robust when applying alternative crude oil prices and China’s stock prices.     

To whom are IAS earnings informative? Domestic versus foreign shareholders' perspectives

Using a sample from the Helsinki Stock Exchange, this paper analyses the information content of dual disclosures of IAS (International Accounting Standards) and LAS (Local Accounting Standards) earnings. Their information content to foreign and domestic shareholders can be distinguished from each other as the unrestricted shares (available to foreign and domestic investors) and the restricted shares (available to domestic investors only) of the same set of companies were listed separately during 198492. The information content is tested with regressions using market-adjusted stock returns measured from the fifty-week period ending in the week of financial statements release. The overall findings suggest that restating local GAAP earnings according to the IAS helps to meet foreign investors' information needs, but is of limited use to domestic investors.     

The effect of domestic and foreign risks on an emerging stock market: A time series analysis

This study investigates the effect of domestic factors – economic, financial and political risk – and foreign factors – global economic policy uncertainty – on the stock market index in Taiwan. To achieve the objective of this study, ARDL, DOLS and Markov Switching tests are employed. Quarterly data is used, covering the period 1997Q1–2015Q2. The findings reveal that the combination of domestic and foreign risk factors has a long-term effect on the stock market index. In addition, declining economic, political and financial risks are associated with the increasing stock market index in Taiwan.

国际金融市场波动溢出效应与动态相关性

在DCC GARCH、DCC EGARCH、DCC TGARCH方法下,采用中、美、日、德、英等国家1993年1月至2013年12月的金融数据,实证得出如下结论：样本国市场利率和股指波动率呈现尖峰、肥尾、有偏的特征,更为符合t分布。样本国市场利率波动表现出显著的溢出效应、杠杆效应和联动效应。样本国股指波动率对中国股指波动率的溢出效应趋于增强,特别在美国金融危机后。样本国利率波动对中国股指波动率具有一定的溢出效应和杠杆效应,但影响程度非常低。治理世界性金融风险,各国当局应加强政策协调性,合理进行风险分担。

基金股票仓位与A股市场走势相关性研究

在划分股市牛熊周期的基础上,采用VECM模型和VAR方法对基金股票仓位变动与股票市场走势之间关系进行研究,结果表明基金股票仓位与股票市场收益率二者之间的关系存在着显著性和非稳定性,即基金作为主要机构投资者对股票市场的走势具有重要影响作用,而在股市的各个不同阶段,基金持仓比例的波动与A股指数收益率二者之间的关系各不相同。     

Earnings Benchmarks and the Information Content of Quarterly Foreign Earnings of U.S. Multinational Companies

The meeting of earnings benchmarks is considered important for investors. The chief financial officers of U.S. companies state that the three most important earnings thresholds to meet are the earnings in the same quarter last year, the analysts' earnings forecast for the current quarter, and zero earnings. These earnings benchmarks have been defined in terms of total earnings. For U.S. multinational firms, total earnings consist primarily of domestic earnings and foreign earnings. We conduct an event study where we examine (1) the stock market reaction to meeting or beating quarterly domestic and foreign earnings benchmarks and (2) the market reaction to the changes in quarterly domestic and foreign earnings, while we control for meeting or beating the analysts' earnings forecast and the analysts' earnings forecast surprise. We find that the quarterly financial statement disclosure of domestic and foreign earnings under Statement of Financial Accounting Standards No. 131 supplies investors with valuable information that was not previously disseminated through financial analysts or other sources. The stock market reaction to meeting or beating foreign earnings from the same quarter in the prior year is stronger than the market reaction to meeting or beating domestic earnings from the same quarter in the prior year.     

中国股市β系数的多尺度特性分析

本文提出一种基于小波方差和小波协方差的β系数估计方法,并通过小波方差和小波协方差的多尺度分解估计出不同尺度上的风险系数,用该方法对中国证券A股市场分行业及投资组合的β系数进行了多尺度估计分析。实证结果表明,我国股市具有复杂的多尺度波动的特征,不同时间尺度上证券市场所表现出的风险不一样,短期投资的风险主要表现在高频波动,投资者应当考虑低尺度下的β系数,而长期投资风险主要表现为低频波动,应当考虑大尺度下的β系数。

The Usefulness of Earnings and Book Value for Equity Valuation in Emerging Capital Markets: Evidence From Listed Companies in the People's Republic of China

This paper examines the relative value relevance in equity valuation of two sets of accounting information of listed Chinese companies which issued the so-called B shares to foreign investors on the Chinese stock exchanges. These firms are required to prepare two sets of financial statements: one based on China's accounting regulations (domestic GAAPs) and the other based on International Accounting Standards (IASs). The study adopted the Ohlson (1995) model and used the Davidson-MacKinnon J-test to assess which one of these two competing sets of accounting information is more closely associated with the share prices. The results showed that earnings and book value reported based on IASs have greater information content than those based on domestic GAAPs. The results of yearly regression analysis generally suggested that the explanatory power of these earnings and book values for share prices increased over time.

Should we worry about the decline of the public corporation? A brief survey of the economics and external effects of the stock market

In recent years, the number of listed companies has been declining in many countries across the world. This paper provides a selective survey of the literature on the real economic effects of the stock market to assess the potential effects of this decline and determine whether it is likely to continue. The leading economic role of the stock market’s primary market, in which firms raise capital by issuing new shares, is to help growing firms secure financing. We discuss providing and certifying information, coordinating investors, and easing the redeployment of capital as the means through which capital allocation can be efficiently achieved. The main economic roles of the stock market’s secondary market, the trade in existing shares, is to provide liquidity to shareholders, to aid in price discovery and to provide diversification opportunities. Positive external effects from an active stock market may arise for consumers, labor and private firms due to increased corporate investment, more socially responsible business strategies and a more positive business climate. Negative external effects on capital allocation and productivity can arise from short-termism, market mispricing, and increased cross-ownership. Local stock markets can spur innovation and foreign direct investment (FDI) and reduce the risk of early cross-border acquisitions. Given the myriad of useful economic functions the stock market performs, a future entirely absent of public companies is difficult to imagine and the decline is therefore likely at some point to come to an end. Whether we need to worry about the decline depends on the relative importance of the positive and negative external effects, a topic we feel warrants more research.     

CAPM模型在上海股票市场的有效性检验

根据资本资产定价模型(CAPM),从上海A股市场随机抽取100支股票,计算它们的收益率,选择上证综合指数为市场组合的市场指数,并利用双层回归分析方法对2007年1月1日至2011年12月31日这段时间的100支股票进行实证检验。虽然很多国外研究表明,CAPM模型在一定程度上能够解释市场收益,并在资产估价、资本预算、投资风险分析方面已经得到了广泛应用,同时也有利于投资者构建最优的证券投资组合,但本文实证研究结果发现,CAPM模型并不适合中国的股票市场,股票预期收益率和系统风险之间不仅不存在正相关的关系,而且也不存在线性关系,除了系统风险外,非系统风险在解释股票收益上也具有一定的作用。     

转型期我国股票市场规制目标的选择

"为国有企业筹资、推动国民经济增长"这一政府股票市场规制的目标已经不能适应经济发展的要求,监管当局应该将"加强投资者利益保护"作为股票市场规制的核心目标,以进一步推进中国股票市场的可持续发展。保护投资者利益是股票市场政府规制目标的核心。造成我国股票市场投资者保护机制缺失的制度性基础在于政府一身兼三职的制度安排,即政府既是国有上市公司、证券交易所、证券公司的实际或者变相的终极所有者,又是投资者利益的守护神,同时也是证券市场的规制与监管者。     

Selecting the portfolio investment strategy under political structure change in United States

This paper investigated whether stock market returns and volatilities were induced by change of long-term political structure. The empirical study finds that the political change is a crucial variable to DJIA and S&P 500 stock returns, but is insignificant to volatilities. But after the 1987 Crash, the political change has a positive effect on DJIA stock returns, and reduced the risk of DJIA and S&P 500. When political structure change, significant economic policies must submit to political realities and those proposed by previous governments often do not get implemented, resulting in market confusion. But following the increasing the consummation of market structure during post-1987 crash, hence, the political change effect increased DJIA stock returns, and reduced the risk of DJIA and S&P 500, and therefore the investors might be able to make a profit when they took active portfolio positions of DJIA.

银行业:收益、股价及投资价值的比较分析

近年来,我国股票市场出现了一个奇异现象,即银行板块业绩优异,但其股价却严重偏离其价值。研究表明,出现这一奇特现象,不是因为该行业的股票盘子大,也不是因为政府融资平台和房地产泡沫等问题的存在导致该行业风险大,而是因为银行股波动性小,同时,也是因为相对来说我国上市公司中银行业经营管理规范、稳健,没有太多可炒作的题材,因此不受市场的投机性资金追捧。     

中国与加拿大新一代管理者的文化差异实证研究

随着经济全球化的发展,中国成为了世界的投资热点,因此,中西方文化差异成为国外投资者非常关切的一个问题。在众多的研究中,Hofstede提出的文化四维度以及对各国的文化差异分析是被广为接受的研究成果。但是由于数据的不可比性,不能客观地反映中国和加拿大两国的文化差异。此外,中国经济环境的变化必然带来文化的不断发展和变化。因此,在新的经济环境下研究中西方文化差异具有现实意义。本文基于对中国和加拿大商务专业大学生的调查,采用Hofstede的文化四维度对比分析中、加新一代管理者的文化差异新趋势及其对企业管理的影响,从而为中西文化的了解提供借鉴。
