In the current study, we identify the announcements that trigger substantial changes in the behaviour of the 10-year US Treasury market, without using the surprise component and, therefore, expectational data. We use a novel model-free approach based on extreme market movements related to price returns, volatility and traded volumes. Our findings corroborate those of previous studies, which were based on expectational data. More importantly, though, we identify two additional announcements (Oil Inventories and the Mortgage Applications), which have not been previously reported. These findings are primarily important to financial analysts and investors.  相似文献

Acquisition announcements influence the stock price of target firms, providing an opportunity for insiders to obtain significant abnormal returns. We study the presence of positive abnormal returns before the announcement date, in target firms, quoted in Euronext markets (Belgium, France, The Netherlands and Portugal) from 2001 to 2007. We investigate whether the pre-announcement run-up of prices can be explained by rumours in the media and the percentage of capital previously owned by the bidding firm, among other factors. We examine cumulative abnormal returns in an event window of 60 days prior the acquisition announcement, with the event date adjusted for the previous disclosure of news about the acquisition, in the media. We compute a run-up index, and find that there are abnormal positive returns before the announcement date, confirming previous studies. We find that a significant part of the run-up is explained by: (i) market anticipation triggered by legitimate sources of information, namely, rumours in the media about the possibility of an acquisition bid and (ii) the percentage of capital previously owned in the target firm, by the bidding firm.  相似文献

In light of the natural gas discoveries in the Mediterranean Sea and their impact on the Israeli economy, I must assess the change in the exchange rate and its impact on the foreign exchange market. There are numerous positive social impacts resulting from the gas discoveries including optimising Israel's energy security and its move to cleaner energy. However, not all of the consequences of discovering natural resources may be positive. One possibly negative outcome could be the well-known phenomenon called the “Dutch disease” in which the discovery of a natural resource can cause a country's currency to spike. To investigate whether the strengthening of the Israeli currency in recent years is a symptom of the “Dutch disease” I used daily and intraday event study methodology to explore the changes in the real exchange rate of the Israeli shekel and the US dollar between 2008 and 2017, according to announcements related to the gas discoveries published during this period. In addition, I examined whether an increase in the real exchange rate was a result of the publication of announcements about natural gas harming the manufacturing and industrial sectors. I found that announcements related to gas discoveries did affect the real exchange rate and caused an appreciation of the Israeli shekel. Investors could analyse the announcements and achieve an abnormal return in the foreign exchange market. In addition, investors' expectations of an appreciation in the real exchange rate causes damage to various manufacturing and industrial sectors.  相似文献

Past empirical studies appear to support the idea that banks and finance companies do not differ in their ability to resolve adverse selection problems associated with issuing new debt. In this article, we find there is a difference. More specifically, using an event study we find larger abnormal returns for secured loan disclosures to lower quality borrowers when the lender is a finance company versus a bank. This suggests the market views finance companies as more effective than banks in evaluating/monitoring lower quality borrowers obtaining secured loans. We posit this is due to finance companies’ greater expertise in this type of lending, resulting from specialization. Our findings extend the literature on how lender identity can influence signals about firm value from loan disclosures. Our results also support recent findings that positive abnormal returns to borrowing firms may not be a general feature across the loan population, but may be restricted to smaller, lower quality borrowers. Finally, we are the first to provide evidence that the market takes loan type into account, not just lender and borrower type, when considering the information embedded in loan disclosures.  相似文献

This study is aimed to identify the impact of credit rating announcements on the stock returns in stock markets and for this purpose, four different sectors of Pakistan stock exchange were selected and from each of these four sectors, different business organizations were selected, i.e. total 32 business organizations were selected. The credit rating announcement data were collected for these 32 business organizations belonging to four different sectors. Totally 101 credit rating announcements were selected and the time period for which the credit rating warnings were selected include last three years period, i.e. from 2014 to 2016. The collected data were analysed by calculating abnormal returns for each of the selected security and average abnormal returns, and cumulative average abnormal returns were calculated for four different sectors. Event study methodology was applied, and t-test and t-stats value were calculated and results were analysed on the basis of t-statistics. The results of analysis identified that credit rating announcements have a significant impact on stock prices and investors and other market participants are earning abnormal returns during two-day period after the announcements are made. In addition, these abnormal returns were either negative or positive, depending upon the nature of credit ratings announced. If the credit rating announced was upgraded, investors enjoyed positive abnormal returns while in case when credit rating announcements were downgraded, then investors bear negative abnormal returns. Finally, the findings of the study identified the applicability of random walk hypothesis on the Pakistan Stock Exchange and Pakistan Stock Exchange confirms the efficient market hypothesis with its semi-strong form of efficiency.  相似文献

Environmental pollution brings severe challenges in the context of a high growing economy of China. Pollution events bring serious ecological cost to the environment, direct costs from sanction, and reputational damage to the listed firms. We study the market reaction to 145 pollution events in China during Jan 2008 and Feb 2015. We find that the 2-day cumulative abnormal returns (CARs) of pollution events are significantly negative, which shows the disciplining effect of the stock market on the listed firms. In addition, pollution events with sanctions have lower CARs than otherwise, which are heterogeneous among different sanction types such as shutting down, fines and rectification. Finally, water pollution has lower CARs than other pollution types. We find that direct economic loss is an important reason for the negative market reactions to pollution events.  相似文献

This study tested the semi-strong form of the EMH in the Kuwait Stock Exchange. This test is conducted by examining the behaviour of stock prices around the date of rights offering announcements. Based on a sample of 69 rights offerings over the period 2004–2013, we find that prices incorporate new information within an average of 4 days. We take this observation as evidence that the Kuwaiti market is semi-strong efficient.  相似文献

Using an event study approach, we seek to estimate the value investors placed on Steve Jobs by investigating the stock market reactions to his death. In the three-day window surrounding his death, the estimated cumulative abnormal returns are ?5.76%. Given the market capitalization of Apple at the time, it can be inferred that investors valued Steve Jobs at 20 billion dollars. While tragic, the news about Jobs’ death is greeted favourably by Apple’s competitors. The competitors appear to be convinced that, without Steve Jobs, they can compete with Apple better.  相似文献

Forecasting and modelling commodities price movements and the activity of energy markets are of real interest to investors and policymakers, especially during turbulent times. This study investigates the volume–returns relationship for two major energy markets (oil and gas) during the recent global financial crisis. Unlike previous studies, we examine this relationship by applying an original fractal approach to intraday data, which has the advantage of accounting for further non-normality, nonstationarity, and fat-tailedness properties. Our study provides two interesting findings. First, we find a significant multifractal relationship between returns and volume in both markets and across all timescales, suggesting nonlinearity in the cross-correlation between returns and volume and rejecting the efficiency assumption. Second, the measure of multifractality in this relationship shows that the magnitude of the fluctuations during bearish and bullish trends affects the volume–return relationship differently, and that the oil market exhibits higher volatility than does the gas market.  相似文献

This paper studies how the announcements of fiscal law changes affect the real estate market, focusing on the case of Spain. An announcement of a future fiscal law change gives the opportunity to buyers to advance or delay purchases to maximize fiscal benefits. In particular, we study announcements and their posterior effects about the mortgage tax laws in 1998, 2010, 2011, and 2013 plus the VAT law in 2012. The paper is based on contextually rich data from 2004 through 2015 for Spain, provided by a real estate agent with a strong presence across the Spanish territory. We use two dependent variables to best capture the changes: time on market of a dwelling and the price discount of the dwelling. Simultaneity bias is avoided by considering that the degree of overpricing and atypicality affects time on market but not the selling price. The identification strategy is improved by considering the type of properties most affected by the changes versus the rest of properties, using a difference-in-difference estimation. We consider two tax policy announcements: income tax credit on dwelling purchases and VAT rate change on the purchases of new dwellings. In the case of the income tax credit, this fiscal policy affects only primary accommodations. In the case of the VAT tax rate, only new houses are affected. We show that credible fiscal policy announcements distort the housing market by temporarily decreasing dwellings’ time on market and their price discounts, to immediately and long-lastingly increase them just after the tax policy expires. There is a negative causal effect of tax policy announcements on the housing market.  相似文献

掌握主权信用评级变动的市场影响及其传染机制,对于投资者、国家金融安全及政府采取应对措施来说都意义重大。文章采用事件研究法,以1990-2013年全球48个经济体发生的评级事件和每日股指收益率数据为样本,实证研究了事件国评级变动对非事件国股票市场的影响及其传染渠道,结果表明:(1)评级下调会对股票市场产生显著为负的超额收益,但评级上调产生的超额收益不显著;(2)股票市场可以提前预测评级下调事件,但不能预测评级上调事件;(3)季风效应对评级调整的市场传染有一定的解释力;(4)净传染效应基本不显著,这说明评级事件的市场传染应该有经济基础,而不是由投资者心理预期这类非基本面因素造成的;(5)溢出效应可以较好地解释评级的市场传染,是评级变动影响市场及传染的主要渠道。文章的结论深化了我们对评级调整如何影响股票市场及其传染渠道的认识,也为中国防范国外主权信用评级变动风险提供了有益启示。  相似文献

In response to increasing environmental concerns, to improve energy security and to conserve energy use, the US government has proposed a new round of Corporate Average Fuel Economy (CAFE) standards. Many studies have focused on how the CAFE standard can be met by various automakers that have sales in the US market, and the costs and benefits of the companies meeting the standard. However, the stock markets’ view on the impact of the standard on automakers’ profitability is largely absent. We study the more recent episode of the CAFE regulation in an effort to try to detect the market response using the standard event study method. Our empirical findings suggest that while the stock market had some responses to the regulation, the large-scale and systematic reaction to the regulation is absent. In addition, the market response pattern to the regulation appears to be tied to the individual company’s compliance condition if there is any significant response at all.  相似文献

This article investigates whether the market reaction to second-hand information is due to price pressure or information dissemination. We use the perspective of attention grabbing to analyse the market reaction to the dissemination of analysts’ recommendations published in print media. This perspective is able to explain the asymmetric market reaction to ‘buy’ and ‘sell’ advice, which is difficult to rationalize within the price pressure hypothesis. We base our empirical analysis on the content of a weekly column in the most important Italian financial newspaper, which publishes past information and analysts’ recommendations on listed companies. Our findings show asymmetric price and volume reactions on the publication day. Contrary to previous evidence, we document a positive relationship between the number of analysts quoted in the column and the price (volume) increase associated with positive recommendations. Because the weekly columns seem to simply attract investors’ attention, with no additional new information, observing a reaction positively related to the column’s salience (proxied by the number of quoted analysts) is natural. In addition, we find that the market reaction is higher when the order size is lower, i.e., when individual investors’ trades constitute a higher fraction of the total trading activity in the market.  相似文献

This paper explores how elections impact stock markets across diverse political institutions. I argue that electoral and party systems impact the fragmentation, credibility, and predictability of electoral information, influencing levels of uncertainty resolved by elections and leading to distinct stock market reactions. First, elections in majoritarian electoral systems produce larger cumulative abnormal returns (CARs) than elections in proportional representation systems. Second, the weaker institutionalized a party systems is, the larger are the CARs around elections. Third, these two institutional variables interact. Elections in majoritarian (proportional representation) systems with weak (strong) party system institutionalizations will have particularly large (small) CARs. I formally derive these propositions, conduct event studies of the impact of 87 elections on SMs in 21 countries from 1999 to 2016, and analyze four case studies.  相似文献

融资融券设计初衷是通过融资加强市场流动性和通过融券提供投资者规避价格下跌风险的金融工具,改善由供求关系严重失衡导致市场巨幅震荡的局面,实现资本市场长期稳定的目标。实际操作中,融资融券疏通货币市场和资本市场间的资金流动,撬动巨额资金涌入股市;融资规模扩张过快而融券做空力量薄弱,业务结构发展严重失衡,导致两融业务具有“小冲击、大波动”的金融加速效应,放大了外部冲击引起股价上涨和下跌的幅度。协整回归分析表明,两融业务规模的扩张和收缩对上证指数涨跌具有显著的同向影响。TGARCH事件模型结果进一步证实融资融券从稳定股价到加剧波动的功能变化。随着标的股票扩容和业务常规化,两融业务导致股市投机过度,加剧了沪深两市的资产价格异动,没有达到平抑波动的设计预期。  相似文献
