This study compares the performance of the ISD, the GARCH (1,1) , the historical volatility estimates and of two lagged trading volume measures for predicting the Swiss Stock Market Index's (SMI) volatility. The ISD has a superior daily informational content than the GARCH (1,1) estimate and retains unbiased but decreasing explanatory power over up to 20 days ahead horizons. Mean and spread daily volume measures play a significant correcting role when forecasting stock market volatility over daily and longer intervals respectively and clearly dominate the GARCH (1,1) forecasts. Their significance emphasises heterogeneous horizon traders' influence on the SMI volatility time series properties  相似文献

This paper explores a wide range of corporate restructurings, all available deals from wire services, in the banking and insurance sectors that led to bancassurance ventures. An event study methodology is employed to calculate excess returns on and around the deals’ announcement date. Using both univariate and multivariate analysis the paper finds bank driven mergers, deal's size and regional categorization all triggering positive and significant market reactions. Unlike the univariate framework, multivariate analysis shows that geographic focus and language are not significant factors. The results also indicate that markets are indifferent with respect to bank withdrawals from the bank‐insurance operations. Finally, Canadian, U.S. and European bank‐insurance deals produce positive results, while Australasian bidders offer statistically insignificant equity returns.  相似文献

Who Gambles in the Stock Market?   总被引:1,自引:0,他引:1  
This study shows that the propensity to gamble and investment decisions are correlated. At the aggregate level, individual investors prefer stocks with lottery features, and like lottery demand, the demand for lottery-type stocks increases during economic downturns. In the cross-section, socioeconomic factors that induce greater expenditure in lotteries are associated with greater investment in lottery-type stocks. Further, lottery investment levels are higher in regions with favorable lottery environments. Because lottery-type stocks underperform, gambling-related underperformance is greater among low-income investors who excessively overweight lottery-type stocks. These results indicate that state lotteries and lottery-type stocks attract very similar socioeconomic clienteles.  相似文献

The purpose of International Financial Reporting Standards (IFRS), adopted mandatorily by European listed firms in 2005, is to increase the transparency and the comparability of accounting information, which should have led to improvements in these firms’ information environments. This study uses market microstructure proxies for information asymmetry to examine the effects of IFRS adoption on the level of information asymmetry in the Spanish stock market. Therefore, we consider a setting with substantial differences between local standards – Spanish Accounting Standards (SAS) ? and IFRS and where the level of enforcement is low. By controlling for conventional determinants of information asymmetry and firms’ characteristics that influence their information environments, we find a reduction of information asymmetry after IFRS adoption. Our findings suggest that the mandatory switch from local accounting standards to IFRS conveys benefits to the market, even when the enforcement level is not strong.  相似文献

We investigate earnings announcement lags (period from the end of the reporting period until the announcement date) for the good and the bad quarterly earnings news across different market sentiment periods as well as market reactions thereto. Companies listed on Baltic stock exchanges exhibit clear signs of strategic timing of earnings announcements. Earnings announcement lags for the bad news tend to be longer than those for the good news. This difference is more pronounced during low market sentiment periods. If the release of the bad news is postponed, abnormal return responses remain lower, as expected.  相似文献

This paper develops a factor analysis–based measure for shifts in corporate financial flexibility (FFLEX) that can be observed from public accounting information. Companies that experience positive shifts in FFLEX are associated with higher future investment growth opportunities. We show that FFLEX is a robust determinant of future stock returns. Firms that have increased their financial flexibility are associated with lower stock returns in the subsequent period. A zero‐cost return portfolio produces a significant positive monthly premium of 0.69%, which is driven by covariance (risk). Risk inherent in the flexibility factor is not explained away by either prominent pricing characteristics or factors.  相似文献

This study examines the effects on the stock market unitaryrisk premium and volatility associated with the listing of stockand stock index derivatives in Switzerland. Based on a univariateGARCH (1,1) specification of the stock index variance and atime-varying unitary risk premium representation, we can rejectthe hypothesis that stock and stock index derivatives listingsdo not affect the total risk premium. Contrarily to previousempirical evidence, we find that derivatives listings affectboth the conditional market returns’ variance and theunitary risk premium through structural shocks. The gradualmarket completion hypothesis is further corroborated in that,cumulatively, the three stock and stock index options futuresderivatives listings reduced the unitary risk premium whilethe marginal impact of each successive listing decayed.

This article examines the effectiveness of momentum strategy at the industry level in the Chinese stock market. We find that the intermediate-horizon momentum effect is stronger in industries with higher competition. This effect is consistent with the hypothesis that information contained in firms from highly competitive industries is vague and hence leaves more space for behavioral biases, which leads to the momentum effect. Alternatively, the measure of the Herfindahl–Hirschman index potentially captures the size effect in explaining this phenomenon. Moreover, concentrated industries experience a pronounced lead-lag effect of big firms on small firms, which is a potential explanation for the contrarian strategy. We do find that the short-horizon contrarian effect is pronounced in highly concentrated industries.  相似文献

Listing on a stock exchange is one of the most significant events in a company's life cycle. Using a case study approach we examine why companies in Fiji list on a stock exchange. The various factors that have been found to motivate companies to list include enhancing their image and reputation, increasing the firm's value and introducing better financial and managerial practices. Importantly, the accessing of new sources of finance has not been a determinant of a company's listing decision. The findings imply that in emerging economies, stock exchange listing can be perceived as a status symbol .  相似文献

This paper examines the reliability of financial analysts’ consensus earnings forecasts in the 1990s. Analysts are often accused of having fuelled the stock market boom with exaggerated evaluations of firms’ prospects. However, this criticism primarily refers to the analysts’ buy recommendations rather than earnings forecasts. Although biases in earnings forecasts have been reported since the 1980s, a systematic study capturing the period of ‘irrational exuberance’ until 2000 on the German stock market has not yet been published. Our data set consists of DAX100 firms, leaving out the peculiarities of forecasting earnings (or rather losses) of young technology firms. To evaluate the information content of analysts’ forecasts, we confront them with five alternative forecasting models. The empirical results reveal that analysts’ forecasts were too optimistic throughout the entire sample period. However, contrary to the increase in stock prices, the optimistic bias has declined over time. If the bias is removed, the analysts’ consensus forecasts significantly outperform all other models considered. Thus, the forecasts seem to be informative with respect to earnings differences, even if the market level of earnings is optimistically overstated.  相似文献

The investor recognition hypothesis and the bonding hypothesis, which help us understand the market quality of stocks that are cross-listed on different stock markets, imply improved market efficiency after cross-listing because of increased investor participation. However, the noise trading of inexperienced investors in the Chinese stock market negatively affects market efficiency. By employing propensity score matching and multivariate regression analysis, we show that the increased individual investor participation actually lowers market efficiency in their home market after cross-listing. This effect is more evident for stocks that were either listed first on the Chinese stock market or listed on the Chinese stock market and the Hong Kong stock exchange (SEHK) on the same date than for stocks that were listed first on the SEHK.  相似文献

We aim to tackle the longstanding debate on whether stock liquidity enhances or impedes firm innovation. This topic is of interest because innovation is crucial for firm‐ and national‐level competitiveness and stock liquidity can be altered by financial market regulations. Using a difference‐in‐differences approach that relies on the exogenous variation in liquidity generated by regulatory changes, we find that an increase in liquidity causes a reduction in future innovation. We identify two possible mechanisms through which liquidity impedes innovation: increased exposure to hostile takeovers and higher presence of institutional investors who do not actively gather information or monitor.  相似文献

We test the impact of investor sentiment on a panel of international stock markets. Specifically, we examine the influence of investor sentiment on the probability of stock market crises. We find that investor sentiment increases the probability of occurrence of stock market crises within a one‐year horizon. The impact of investor sentiment on stock markets is more pronounced in countries that are culturally more prone to herd‐like behavior, overreaction and low institutional involvement.  相似文献

Do related markets reflect new information simultaneously? For high‐yield bonds, a large abnormal price decline in a corporation's most liquid bond over a month is followed by an average abnormal stock price decline of ?1.42%. This effect is larger for stocks that have increased in value and for volatile stocks. It is also larger for bonds with high coupons and shorter maturities. These results support the view that high‐yield corporate bonds have an informational edge when news is negative and stock returns are noisy, and add to the growing literature on the substantial lags in price discovery between related markets.  相似文献

This study examines whether the effectiveness of institutional monitoring depends on the economic conditions of emerging capital markets. We use trading volume data by investor type to compute a proxy for total institutional ownership. We then analyze the impact of the proxy variable on accounting earnings attributes and examine whether the association between the two depends on an expectation of market growth. We find that the effect of institutional monitoring decreases when market growth is expected to be low, implying that market growth may be a critical determinant of institutional investors’ long-term monitoring effectiveness in emerging capital markets.  相似文献

Integrated reporting (<IR>) is an emerging international corporate reporting initiative to address limitations to extant corporate reporting approaches, which are commonly criticized for being both voluminous and disjointed. While <IR> is gaining in popularity, current momentum has been limited due to a lack of clear evidence of its benefits. Utilizing the most suitable setting currently available, being discretionary disclosures made by listed companies on the Johannesburg Stock Exchange, this study provides evidence that analyst forecast error reduces as a company's level of alignment with the <IR> framework increases. Further, the improved alignment is associated with a subsequent reduction in the cost of equity capital for certain reporting companies. The results are obtained after controlling for factors relating to financial transparency and the issuance of standalone non‐financial reports, which suggests that <IR> is providing incrementally useful information to the capital market over and above existing reporting mechanisms.  相似文献

Using a sample of common stocks traded on the Istanbul Stock Exchange from February 1997 to April 2008, we test whether the conditional capital asset pricing model (CAPM) accurately prices assets. In our empirical analysis, we closely follow the methodology introduced in Lewellen and Nagel (2006). Our results show that the conditional CAPM fares no better than the static counterpart in pricing assets. Although market betas do vary significantly over time, the intertemporal variation is not large enough to drive average conditional alphas to zero.  相似文献

We derive a formula for the expected return on a stock in terms of the risk‐neutral variance of the market and the stock's excess risk‐neutral variance relative to that of the average stock. These quantities can be computed from index and stock option prices; the formula has no free parameters. The theory performs well empirically both in and out of sample. Our results suggest that there is considerably more variation in expected returns, over time and across stocks, than has previously been acknowledged.  相似文献

This paper examines the link between the issuance of subordinated debt by commercial banks and market discipline. Using cross-sectional and time-series data from 2002 to 2007, we empirically examine the relationship between banks' risk level and their decisions to issue subordinated debts in Taiwan. In particular, we test the hypothesis that the commercial banks with low risk levels prefer to issue subordinated debts more than high-risk banks do, and we reject the hypothesis. We conclude that the application of subordinated debt is not a mature channel for providing market discipline for commercial banks in Taiwan. We offer potential reasons for this finding and discuss the policy implications of our findings.  相似文献

Mandatory pension contributions (MCs) are negative shocks to a firm's liquidity that can unfavorably impact its cost of capital, financing, and investment plans. We examine whether firms faced with MCs use both noncash (NEM) and cash‐generating earnings management (CEM) to partially offset their negative effects. Firms increase CEM, but not NEM, when they experience MCs. We also find that earnings management associated with MCs does not substantially lower the weighted cost of capital or boost external funding and investment. Our findings suggest that MC firms use CEM as it directly generates cash to fund MCs, while NEM does not.  相似文献
