This article examines the impact of macroeconomic news announcements on bond market expectations, as measured by option‐implied probability distributions of future bond returns. The results indicate that expected bond market volatilities increase in response to higher‐than‐expected inflation and unemployment announcements. Furthermore, the asymmetries in bond market expectations are found to be affected mostly by surprises in inflation and economic production figures. In particular, it is found that higher‐than‐expected inflation announcements cause optionimplied bond return distributions to become more negatively skewed or less positively skewed, implying a shift in market participants' perceptions toward future increases in interest rates. Finally, the results indicate that market expectations of future extreme movements in bond prices are virtually unaffected by macroeconomic news releases. Some evidence is found, however, that suggests that after extreme surprises in inflation announcements market participants attach higher probabilities for extreme movements in bond prices. © 2005 Wiley Periodicals, Inc.

We investigate changes in market quality in the US and Canada during macroeconomic news announcements. We measure market quality in terms of returns dependence, the cost of trading, and pricing errors. Using a sample of cross‐listed stocks and macroeconomic news from both countries, we document that market quality is generally higher in the US than in Canada. The pattern of intraday serial dependence in returns reveals that it takes investors about 5 min less to react to order imbalances in the US than in Canada. We further observe that, around announcement periods, transaction costs increase more in Canada than in the US, suggesting that the US market offers better liquidity. More information is also incorporated into the US market. These results support the view that the US is a prime target for cross‐listing, and are robust to different types of assets and time specifications.  相似文献

We explore the determinants of intraday volatility in interest‐rate and foreign‐exchange markets, focusing on the importance and interaction of three types of information in predicting intraday volatility: (a) knowledge of recent past volatilities (i.e., ARCH or Autoregressive Conditional Heteroskedasticity effects); (b) prior knowledge of when major scheduled macroeconomic announcements, such as the employment report or Producer Price Index, will be released; and (c) knowledge of seasonality patterns. We find that all three information sets have significant incremental predictive power, but macroeconomic announcements are the most important determinants of periods of very high intraday volatility (particularly in the interest‐rate markets). We show that because the three information sets are not independent, it is necessary to simultaneously consider all three to accurately measure intraday volatility patterns. For instance, we find that most of the previously documented time‐of‐day and day‐of‐the‐week volatility patterns in these markets are due to the tendency for macroeconomic announcements to occur on particular days and at particular times. Indeed, the familiar U‐shape completely disappears in the foreign‐exchange market. We also find that estimates of ARCH effects are considerably altered when we account for announcement effects and return periodicity; specifically, estimates of volatility persistence are sharply reduced. Separately, our results show that high volatility persists longer after shocks due to unscheduled announcements than after equivalent shocks due to scheduled announcements, indicating that market participants digest information much more quickly if they are prepared to receive it. However, contrary to results from equity markets, we find no evidence of a meaningful difference in volatility persistence after positive or negative price shocks. © 2001 John Wiley & Sons, Inc.

This study uses the tick data for foreign‐currency futures to examine risk–return relationships on macroeconomic announcements. This study—different from previous studies—examines the risk–return relationship by capturing the announcement effect on returns with announcement surprises and on volatilities with announcement dummies simultaneously in a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model. Strong risk–return relationships are detected for the first min after the announcements. Furthermore, the return–risk tradeoff ratios differ across currencies and across macroeconomic indicators. The same information can be more profitable when acted on the more liquid currency futures. © 2002 Wiley Periodicals, Inc. Jrl Fut Mark 22: 729–764, 2002  相似文献

The authors investigate the effects of macroeconomic announcements on the realized correlation between bond and stock returns. It was found that it is not so much the surprise component of the announcement, but the mere fact that an announcement occurs that influences the realized bond—stock correlation. The impact of macroeconomic announcements varies across the business cycle. Announcement effects are highly dependent on the sign of the realized bond—stock correlation, which has recently gone from positive to negative. Macroeconomic announcement effects on realized bond and stock volatilities are also investigated. Our results are robust across 8:30 A.M. and 10:00 A.M. announcements. © 2007 Wiley Periodicals, Inc.

This study examines the impact of weekly crude oil storage announcements on oil futures and options prices. We document evidence of a strong announcement day effect on both markets, and find prices to move in anticipation of the inventory surprise. Futures returns significantly decrease with positive surprises and increase with negative surprises. There is no evidence of an asymmetric impact on futures prices. Near‐the‐money options exhibit the greatest price sensitivity, and the magnitude of the price response of both futures and options declines with maturity. The results remain robust even after controlling for various macroeconomic and other storage‐related news variables.  相似文献

Bloomberg and Briefing.com provide competing forecasts for prescheduled macroeconomic announcements. This study examines the accuracy of these forecasts and market reactions to announcement surprises. Our results show that the Bloomberg survey is slightly more accurate than the Briefing.com survey. More importantly, although announcement surprises based on both surveys have a significant effect on the trading activities and returns of S&P 500 futures contracts, the Bloomberg survey subsumes the explanatory power of the Briefing.com survey. The findings suggest that on average Bloomberg forecasts are more consistent with the market consensus view. In addition, we provide evidence of asymmetric market reactions to positive versus negative announcement surprises. In particular, the market reacts strongly to inflation news in the Consumer Price Index (CPI) and Producer Price Index (PPI) announcements and negative shocks in housing price, personal spending, and retail sales.  相似文献

Using hand‐collected news headlines for a large sample of listed firms in China over a period of 2000–2015, we investigate the cross‐sectional relation between media coverage and stock returns. Our results document that no‐media coverage stocks earn 55 basis points a month higher than stocks that are featured in the media. This result is robust after controlling for common risk factors and is not driven by short‐run return reversals. Further analysis provides evidence to support the investor recognition hypothesis, suggesting that mass media may play an incremental role in providing a supplement to traditional channels of information dissemination. Therefore, results in this paper are of interests to both investors and regulators on drivers of stock returns.  相似文献

In this article, we examine the impact of 21 different types of scheduled macroeconomic news announcements on S&P 100 stock‐index option volume and implied volatility. We find that there is a 2‐h delay after the announcement before volume increases. However, there is an immediate increase in volatility, which slowly dissipates over several hours. Further analysis shows that most of the high volume and volatility after announcements come from the announcements that are considered bad news. That is, bad news creates high volatility and high volume, whereas good news elicits lower volume and is not associated with higher volatility. These results are not consistent with the predictions of any one model. We also find that the announcements that cause the largest reaction in the equity option market are Consumer Credit, Consumer Spending, Factory Inventories, NAPM, and Non‐Farm Payrolls. Six other announcements elicit a mild response. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:315–345, 2003  相似文献

We examine the responses of intraday option-implied volatilities to scheduled announcements of macroeconomic indicators. The increase in implied volatility around macroeconomic news announcements is more pronounced for puts than for calls and is stronger for announcements made during trading hours than for those made during nontrading hours. These effects are also more pronounced in the crisis and postcrisis periods than in the precrisis period. Monetary policy announcements have a more substantial impact on volatility than other announcements have, even after controlling for news surprise components. The impact appears to be greater for policy rate hikes than for policy rate cuts.  相似文献

This article investigates the post-announcement drift (PAD) of stock returns in the Chinese stock market. We use a sample of voluntary trading disclosures to test the hypothesis that an asymmetric PAD exists in a market in which managers are more likely to suppress negative news. We show that a pattern of short-term momentum and long-term reversal in returns persists for up to 250 trading days following the announcement of trading statements in the Chinese stock market. This finding is stronger for positive announcements in terms of the magnitude and the variance of stock returns. Our findings are in line with both Shin’s theoretical predictions and the credibility hypothesis, in which disclosure and asset returns are jointly determined and the adoption of a “sanitisation strategy” in information disclosure generates more volatile returns for firms issuing good news. Further, we show that the latter effect is more pronounced for firms which are partially state-owned, suggesting that they potentially receive more government support, a finding which is in line with the hypothesis that the incentive to suppress negative information is related to a country’s legal/judicial system.  相似文献

In this article a study of the option‐implied probability density function (PDF) of German stock returns is presented. The use of option prices allows for the quantification of the risk‐neutral probability of large movements in the DAX index. Using daily data for the period from December 1995 to May 2002, the mixture of log‐normals specification with a constant maturity of 49 days is estimated. The time series behavior of the option‐implied PDF during episodes of market turbulence is discussed at the outset. The main purpose of the study is to consider the relationship of summary measures of the option‐implied PDF to macroeconomic news, information from the U.S. stock market, and risk premia. The results suggest the existence of a significant spillover from the U.S. stock market. Returns and the volatility of U.S. stock prices have a strong effect on changes in the lower DAX tail probability, but also on the higher moments of the option‐implied PDF. © 2005 Wiley Periodicals, Inc.

The German 10‐year Bund futures contract traded on the Eurex futures and options exchange in Frankfurt became the world's most actively traded derivative product by the end of 1999. In this article, we provide a detailed exploration of the interday and intraday return volatility in the Bund futures contract using a sample of five‐min returns from 1997 to 1998. The evolution of interday volatility is described best by a MA(1)‐fractionally integrated process that allows for the long‐memory features. At the intraday level, we find that macroeconomic announcements from both Germany and the U.S. are an important source of volatility. Among the various German announcements, we identify the IFO industry survey of business climate, industrial production (preliminary), and Bundesbank policy meeting as being by far the most important. The three most significant U.S. announcements include the employment report, the National Association of Purchasing Managers (NAPM) survey, and employment costs. Overall, U.S. macroeconomic announcements have a far greater impact on the Bund futures market than their German counterparts. © 2002 Wiley Periodicals, Inc. Jrl Fut Mark 22:679–696, 2002  相似文献

The present paper considers a constant returns to scale non‐joint production economy with one primary factor (labour). It follows from the non‐substitution theorem that macroeconomic variables are completely determined by the wage–profit distribution in a long‐period position. We investigate the special case in which production in each sector as well as consumption are characterized by means of Cobb–Douglas functions. Despite the non‐linearity, this parametrization allows us to compute sectoral and macroeconomic variables in simple and intuitive equations. As noted in earlier literature, many variables behave differently than would be expected on basis of a one‐sectoral Solow growth model.  相似文献

In this study, we comprehensively examine the volatility term structures in commodity markets. We model state-dependent spillovers in principal components (PCs) of the volatility term structures of different commodities, as well as that of the equity market. We detect strong economic links and a substantial interconnectedness of the volatility term structures of commodities. Accounting for intra-commodity-market spillovers significantly improves out-of-sample forecasts of the components of the volatility term structure. Spillovers following macroeconomic news announcements account for a large proportion of this forecast power. There thus seems to be substantial information transmission between different commodity markets.  相似文献

This paper investigates the impact of timeliness and credit ratings on the information content of the earnings announcements of Greek listed firms from 2001 to 2008. Using the classical event study methodology and regression analysis, we find that firms tend to release good news on time and are inclined to delay the release of bad news. We also provide evidence that the level of corporate risk differentiates the information content of earnings according to the credit rating category. Specifically, firms displaying high creditworthiness enjoy positive excess returns on earnings announcement dates. In contrast, firms with low creditworthiness undergo significant share price erosions on earnings announcement days. We also observe a substitution effect between timeliness and credit ratings in relation to the information content of earnings announcements. Specifically, we find that as the credit category of earnings-announcing firms improves, the informational role of timeliness is mitigated.  相似文献

基于2012年4月30日至2018年12月17日的银行间7天逆回购操作利率,本文首次使用波动率回归拟合的方法,从政策利率的角度改进中国货币政策不确定性指数,并进一步研究了在不同程度货币政策不确定性的情况下,人民币兑美元汇率对宏观经济新闻的反应。收集和构建10项宏观经济新闻后,本文发现当市场参与者普遍不能较为准确地预测未来政策变化的情形时,货币政策不确定性上升,在岸、离岸人民币兑美元汇率对宏观经济新闻的反应显著减弱。当货币政策存在较高不确定性时,市场对未来政策判断的分歧加剧,进而人民币汇率对宏观经济新闻的反应不足。在货币政策不确定性较高时,增加央行的汇率沟通,可以发挥其对宏观经济新闻的补充作用,同时增强市场对宏观经济基本面信息的反应。本文不仅丰富了货币政策不确定性的负面影响、经济后果以及宏观经济新闻的人民币汇率效应相关理论研究,而且为未来货币政策制定、调整和实施提供了有价值的依据,为货币当局进行有效外汇市场干预提供了经验参考。  相似文献

Using Federal Reserve bank stress test announcements, we examine when option traders acquire informational advantage and when they exploit it. We find consistent evidence of informed options trading around announcements. However, when test results are announced in successive weeks we find high abnormal option volume, considerably positive abnormal returns and significant return predictability in the first week, but not the following week. This suggests that informed option traders are able to anticipate upcoming news events and skillfully process public information but it also suggests that trading on acquired information is conditioned on the level of information asymmetry in the market.  相似文献

In this study we analyze the reaction of daily cash and futures prices for several Treasury securities to the release of U.S. macroeconomic news. Some important results are reported. First, consistent with the notion of market integration, the futures market is found to be cointegrated with the corresponding cash market. Second, of the 23 types of periodic macroeconomic announcements, 19 of them have a significant influence on either the cash or futures prices. Most notably, surprises in nonfarm payroll and Treasury budget significantly influence the cash and futures market across the entire maturity spectrum. Third, consistent with the Fisher and real activity hypotheses, macroeconomic news that conveys higher inflation and/or economic growth has a negative influence on cash and futures prices. Finally, hedging with Treasury futures appears to offer investors protection from inflation‐related fluctuations in interest rates, but not against fluctuations arising due to variations in real output. Some important policy implications of the results are offered. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:453–478, 2004  相似文献

The positions of hedgers and speculators are correlated with returns in a number of futures markets, but there is much debate as to the interpretation of such a relationship—whether it reflects private information, liquidity, or trend‐chasing behavior. This paper studies the relationship between positioning of hedgers and speculators and returns in equity futures markets. I propose a novel test of the private information hypothesis: analyzing the effect of public announcements about futures positions on prices, using high‐frequency data in short windows around the announcements. I find that the revelation of speculators' positions is informative to investors more broadly, supporting the private information view. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark  相似文献
