Intraday return and volatility spillover mechanism from Chinese to Japanese stock market

We analyze the mechanism of return and volatility spillover effects from the Chinese to the Japanese stock market. We construct a stock price index comprised of those companies that have substantial operations in China. This China-related index responds to changes in the Shanghai Composite Index more strongly than does the TOPIX (the market index of the Tokyo Stock Exchange). This result suggests that China has a large impact on Japanese stocks via China-related firms in Japan. Furthermore, we find evidence that this response has become stronger as the Chinese economy has gained importance in recent years.     

除息日股票价格波动——基于国际市场的对比实证分析

本文探讨了四个不同地域(美国、英国、日本和中国)的资本市场在金融危机时期,其代表性的蓝筹股在除息日的价格波动行为。实证结果发现:在除息日,对于纽约和上海交易所,股票价格的下跌量等同于红利数额并且没有证据表明超额收益和短期交易的存在;对于东京交易所,股价下跌少于股息量,恰恰相反,伦敦交易所的股票下跌量超过股息额,这表明上述两个交易所的股票在除息日前后存在着异常收益和短期套利交易行为。     

The market for corporate subsidiaries in Japan: An empirical study of trades among listed firms

We investigate trades of wholly- or partially-owned subsidiaries between firms listed on the Tokyo Stock Exchange (TSE) for the years 1996–2010, to explore the economic impact in terms of strategic refocusing, stock market valuation and performance effects. By pairing both sides to each deal, we show differences in firm characteristics, returns, and subsequent performance of buying and selling firms. Unlike mergers between whole firms, most subsidiary deals straddled different industries. Most sellers were larger, more diversified and less profitable than buyers. Our event study reveals that abnormal returns were positive for buyers yet insignificantly different from zero for sellers. However, subsidiary sales in the core business earned negative returns, the more so the larger the deal. An analysis of ex-post operating results shows that the performance of sellers often declined after the trade, in particular for firms that divested a core-related subsidiary. We conclude that subsidiary trades in Japan in this period contributed importantly to strategic repositioning and a more efficient use of corporate assets.     

Exchange rate exposure and risk management: The case of Japanese exporting firms

This paper investigates the relationship between Japanese firms’ exposure to the exchange rate risk and their risk management. Following Dominguez (1998) and others, we first estimate the firms’ exposure to the exchange rate risk by regressing their stock prices on the exchange rate and the market portfolio. We next investigate possible influences of various risk management measures on the firms’ foreign exchange exposure. Risk management variables include financial and operational hedging, the invoice currency choice, and the price revision strategy (pass-through) of 227 listed firms in 2009, which were collected from a questionnaire survey of Japanese firms listed in the Tokyo Stock Exchange. Our main findings are as follows: First, firms with greater dependency on sales in foreign markets have greater foreign exchange exposure, judged by the market. Second, the higher the US dollar invoicing share, the greater the foreign exchange exposure is, which can be reduced by both financial and operational hedging. Third, yen invoicing reduces foreign exchange exposure. These findings indicate that Japanese firms use a combination of risk management tools to mitigate the degree of exchange rate risk.     

An efficient market? Going public in London, 1891–1911

There have been claims that British capital was not well deployed in Victorian Britain. There was, allegedly, a lack of support for new and dynamic companies in comparison to the situation in Germany and the US. We find no evidence to support these claims. The London Stock Exchange welcomed young, old, domestic, and foreign firms. It provided funds to firms in old, existing industries as well as patenting firms in ‘new‐tech’ industries at similar costs of capital. If investors did show a preference for older and foreign firms, it was because those firms offered investors better long‐run performance. In addition, we show some evidence that investors who worked in the same industry and lived close to the firm going public were allotted more shares in high‐quality initial public offerings.     

The winner–loser effect in Japanese stock returns

This study examines the winner–loser effect using stocks listed on the Tokyo Stock Exchange (TSE) from 1975 to 1997. We uncover significant return reversals dominating the Japanese markets, especially over shorter periods such as 1 month. No momentum effect is observed, however. The 1-month return reversal remains significant even after adjusting for firm characteristics or risk. While the 1-month return reversal is not related to industry classification, it is partially a result of higher future returns to loser stocks with low trading volume. Our results show that investor overreaction may be a possible explanation for the 1-month return reversal in Japan.

自愿性信息披露对公司价值的影响研究

根据代理理论与信号理论,资质优良的公司有动力通过自愿性信息披露降低代理成本或突出自身竞争优势,因此,作为一种信号传递机制或契约安排,自愿性信息披露将对上市公司价值产生影响.以此为切入点,文章选取了沪市2004年制造业公司作为研究样本,实证检验了上市公司自愿性信息披露与公司价值之间的关系,结果发现,自愿性信息披露与公司价值之间呈现显著的正相关关系;由此,有必要进一步地加强我国上市公司的自愿性信息披露制度.     

Especial Motives for Accounting Fraud ——A Case Study of Insider Trading

Guilin Jiqi is a pharmaceutical company listed on Shenzhen Stock Exchange in 1997. Possible motives for her accounting fraud in 2000 are thoroughly analyzed. Guilin Jiqi made up the accounting profit in the semi-annual report. Interestingly, the employee shares of Guilin Jiqi began to be tradable from June. After rejecting other possibilities, we find that this accounting fraud is possibly intended to help her employees, except top managers, to sell their shares at a huge profit.     

Market microstructure and price discovery on the Tokyo Stock Exchange

This paper compares the price discovery processes at the opening and closing transactions for the fifty largest stocks trading on the Tokyo Stock Exchange. Open-to-open returns are found to have a greater volatility and a more negative autocorrelation pattern than close-to-close returns, similar to the pattern we found on the New York Stock Exchange. The results are consistent with pricing over-reaction at the opening and partial price-adjustment at the close. These patterns persist over time and prevail when estimated for returns conditional on the contemporaneous market effect. Our analysis of daytime and overnight returns suggest that pricing errors at the opening are corrected over the trading day. We present a new measure of volatility — the relative dispersion of stock returns around the market return — and find that it is greater at the opening, consistent with a more noisy price discovery process.     

ARCH versus information-based variances: evidence from the Tokyo Stock Market

By using both the individual stock prices quoted on the Tokyo Stock Exchange and their price index (TOPIX), this paper examines whether the conditional variance of stock returns is characterized by the auto-regressive-conditional-heteroskedasticity (ARCH) effect or the information-based effect. The paper finds that the inclusion of the trading volume in both generalized ARCH (GARCH) and exponential GARCH (EGARCH) specifications eliminates the ARCH effect for individual stocks and the TOPIX. The paper explains the reasons for these results. The findings suggest strong support for the information-based variance model which gives a parallel explanation to the ARCH-type models.

Tick size change and liquidity provision on the Tokyo Stock Exchange

The Tokyo Stock Exchange (TSE) introduced a change in its minimum tick sizes on April 13, 1998, for stocks traded at certain price ranges. We investigate the liquidity and market quality of the stocks affected by the tick size change, using a unique and comprehensive tick-by-tick data. We find that the quoted spread (effective spread) declined significantly by 20 to 50 percent (by 24 to 60 percent) after the tick size change. Reductions in spread are greater for firms with greater tick size reductions, greater trading activity, and higher transitory component in the bid–ask spread. Although investors are more aggressive in posting quotes, there is no definite evidence of an increase in trading volume. Overall, our evidence is consistent with the hypothesis that the minimum tick size creates economic rents for liquidity providers, which is lowered upon tick size reduction. J. Japanese Int. Economies 21 (2) (2007) 173–194.

Corporate Valuation and Dividends: UK Evidence from Panel Unit Root and Cointegration Tests

In this study we investigate the long run relationship between dividends and corporate valuation with the use of panel unit root tests and panel cointegration analysis. The long run relationship is estimated using fully modified OLS for a panel consisting of 479 firms listed on the London Stock Exchange over the time period 1984–2007. The empirical results provide clear support for the hypothesis that there is a single equilibrium relation between market value, book value, earnings and dividends, and that dividends have a positive impact on corporate valuation.

Market Risk in Demutualized Self-Listed Stock Exchanges: An International Analysis of Selected Time-Varying Betas

Abstract

This article examines market risk in four demutualized and self-listed stock exchanges: the Australian Stock Exchange, the Deutsche Börse, the London Stock Exchange and the Singapore Stock Exchange. Daily company and the Morgan Stanley Capital International (MSCI) Index returns provide the respective asset and market portfolio data. A bivariate GARCH model is used to estimate time-varying betas for each exchange from listing until 7 June 2005. While the results indicate significant beta volatility, unit root tests show the betas to be mean-reverting. These findings are used to suggest that despite concerns that demutualized and self-listed exchanges entail new market risks that merit regulatory intervention, the betas of the exchange companies have not changed significantly since listing. However, market risk does vary considerable across the exchanges, with mean time-varying betas of 0.56 for the Deutsche Börse, 0.66 for the London Stock Exchange, 0.78 for the Singapore Stock Exchange, and 0.95 for the Australian Stock Exchange.     

International linkages of the Japanese stock market

Using daily open-to-close and close-to-open stock prices, this paper examines whether there are any lead–lag relationships between the Tokyo Stock Exchange and the other G7 stock markets. In particular, this paper analyzes whether the movements of other markets in the preceding trading session can be used to formulate profitable strategies to trade in Nikkei.     

Wholesalers,indirect exports,geography, and economies of scope: Evidence from firm transaction data in Japan

This study examines wholesalers’ roles in manufacturers’ exports in Japan. First, it is shown that, like in the case of manufacturing sector, a productivity sorting on the overseas activities is also present in the case of wholesalers. Namely, only the most productive wholesaler firms can engage in foreign direct investment, and the next productive wholesaler firms can participate in export activities, and the least productive wholesaler firms do domestic transactions only. Second, we investigate how the wholesalers facilitate manufacturers’ export activities in the form of indirect exports. We have found that the wholesalers through which manufacturing firms indirectly export their goods are predominantly located in Tokyo or Osaka. The probability of indirect exports is negatively correlated with distance between manufacturers and wholesalers, but there are certain threshold distances at 300–500 kilometers, over which the chance of indirect exports turns null. Another notable finding is that wholesalers’ productivities have positive correlation with the chances of indirect exports whereas manufacturers’ productivities do not matter. The number of manufacturers from which a wholesaler purchases goods, is found to have a positive correlation with the probability of indirect exports, a type of economies of scope effect.
