US macroeconomic news effects around the US and European financial crises: Evidence from Brazilian and Mexican equity indices

We examine the intraday index return and volatility responses of two Latin American equity markets to US macroeconomic news releases around the periods of the US and European financial crises. We find that while index return is more sensitive than volatility to macroeconomic news in general, the five-minute Brazilian and Mexican index volatilities respond especially strongly to US news surprises, with the Brazilian response being more pronounced, especially during the expansion period. Among the macroeconomic indicators tested, FOMC rate decisions exhibit the highest impact on volatility, and there is evidence of asymmetric response to positive versus negative news.     

Simultaneous monetary policy announcements and international stock markets response: An intraday analysis

This paper investigates the return and volatility response of major European and US equity indices to monetary policy surprises by utilizing extensive intraday data on 5-min price quotes along with a comprehensive dataset on monetary policy decisions and macroeconomic news announcements. The results indicate that the monetary policy decisions generally exert immediate and significant influence on stock index returns and volatilities in both European and the US markets. The findings also show that press conferences held by the European Central Bank (ECB) that follow monetary policy decisions on the same day have a clear impact on European index return volatilities. This implies that they convey additional important information to market participants. Overall, our analysis suggests that the use of high frequency data is critical to separate the effect of monetary policy actions from those of macroeconomic news announcements on stock index returns and volatilities.     

Scheduled domestic and US macroeconomic news and stock valuation in Europe

This paper investigates whether investors on European stock markets regard news announcements about domestic and US macroeconomic variables as an important source of information when valuing stocks. To assess the importance of scheduled domestic and US macroeconomic news announcements, implied volatilities are analyzed on the German and Finnish stock markets. The results show that the US employment report and the Federal Open Market Committee (FOMC) meeting days have a significant impact on implied volatility on both European markets. The domestic news announcements have no effect on implied volatility on either of the markets. The results indicate that the US macroeconomic news announcements are valuable sources of information on European stock markets while domestic news releases seem to be unimportant.     

Central bank communication and exchange rate volatility: a GARCH analysis

We examine the effects of the Czech National Bank communication, macroeconomic news and interest rate differential on exchange rate volatility using generalized autoregressive conditional heteroscedasticity model. Our results suggest that central bank communication has a calming effect on exchange rate volatility. The timing of central bank communication seems to matter, too, as financial markets respond more to the communication before the policy meetings than after them. Next, macroeconomic news releases are found to reduce exchange rate volatility, while interest rate differential seems to increase it.     

Intraday Seasonalities and Macroeconomic News Announcements

Using a data set consisting of more than five years of 5‐minute intraday stock index returns for major European stock indices and US macroeconomic surprises, conditional means and volatility behaviour in European markets were investigated. The findings suggest that the opening of the US stock market significantly raises the level of volatility in Europe, all markets responding in an identical fashion. Furthermore, US macroeconomic surprises exert an immediate and major impact on both the European stock markets’ intraday returns and volatilities. Thus, high frequency data appear to be critical for the identification of news impacting the markets.     

The efficiency of the information processing in the Australian dollar market: Price discovery following scheduled and unscheduled news

We jointly investigate the responses of the Australian dollar (AUD) order flow, realized volatility and trading volume to unscheduled Reuters news headline alerts and scheduled macroeconomic news from Australia, Japan, the Eurozone, the U.K., and the U.S. over the period 2 January 2007 to 31 December 2009. We find that Reuters foreign exchange and fixed income market news headlines are important, and those headlines that arrive during the Australian offshore trading hours matter more. Furthermore, the AUD market responded mostly to Australian and U.S. macroeconomic news which have direct relevance for the exchange rate. We also find that better than expected Japanese and Eurozone macroeconomic news elicited a response in the AUD and also that better than expected news from Australia, U.S. and U.K. matter more. Finally, we find that the volume response to news decreases at a slower rate than the volatility response and that order flows for the AUD respond only to scheduled news.     

The intraday determination of liquidity in the NYSE LIFFE equity option markets

We exploit an extensive high-frequency data set of all individual equity options trading at New York Stock Exchange London International Financial Futures and Options Exchange (Amsterdam, London and Paris) in order to study the determination of liquidity during the trading day. In particular, we focus on two main aspects of option liquidity: (i) the intraday behaviour of equity option liquidity and its determinants and (ii) the influence of macroeconomic events and commonality on intraday equity option liquidity. Inventory management models cannot explain the intraday variation in option spreads and depths. Instead, we show that the option liquidity measures are strongly correlated with option volatility. Increases in volatility are associated with decreases in liquidity, a finding that is in line with information asymmetry models and the derivatives hedging theory. However, the relationship between spreads and volume varies across the three markets. Option liquidity reacts strongly to macroeconomic news announcements, especially US events. The average systematic liquidity component is 12% for Amsterdam, 14% for London and 16% for Paris.     

Volatility in the foreign currency futures market

We examine the volatility implications of around-the-clock foreignexchange trading with transaction data on futures contractsfrom the Chicago Mercantile Exchange and the London InternationalFinancial Futures Exchange. We find higher U.S.-European andU.S.-Japanese exchange-rate volatilities during U.S. tradinghours and higher European cross-rate volatilities during Europeantrading hours. While the disclosure of private information throughtrading may partly explain these volatility patterns, we concludethat the increased volatility is more likely driven by macroeconomicnews announcements. An analysis of inter- and intraday dataalso reveals that volatility increases at times that coincidewith the release of U.S. macroeconomic news.     

The macroeconomic content of international equity market factors

Although existing research has examined the association between macroeconomic data and particular equity markets, little is known regarding the economic content of the latent factors common to international equity markets. This paper considers the macroeconomic information incorporated in unobserved common equity market factors, as well as the possibility that the macroeconomic sensitivities of the factors differ across alternative levels of volatility. Several models are estimated for 15 developed equity markets to examine the economic composition of the common factors, thereby providing an alternative perspective on the economic fundamentals underlying equity markets. A formal Bayesian selection process suggests that a common structure incorporating global and European factors is preferred to the baseline case of a single global factor or the extended scenario of dual global factors. The common factors are associated with a small set of macroeconomic variables.     

The reaction of asset prices to macroeconomic announcements in new EU markets: Evidence from intraday data

We estimate the impact of macroeconomic news on composite stock returns in three emerging European Union financial markets (the Budapest BUX, Prague PX-50, and Warsaw WIG-20), using intraday data and macroeconomic announcements. Our contribution is twofold. We employ a larger set of macroeconomic data releases than used in previous studies and also use intraday data, an excess impact approach, and foreign news to provide more reliable inferences. Composite stock returns are computed based on 5-min intervals (ticks) and macroeconomic news are measured based on the deviations of the actual announcement values from their expectations. Overall, we find that all three new EU stock markets are subject to significant spillovers directly via the composite index returns from the EU, the U.S. and neighboring markets; Budapest exhibits the strongest spillover effect, followed by Warsaw and Prague. The Czech and Hungarian markets are also subject to spillovers indirectly through the transmission of macroeconomic news. The impact of EU-wide announcements is evidenced more in the case of Hungary, while the Czech market is more impacted by U.S. news. The Polish market is marginally affected by EU news. In addition, after decomposing pooled announcements, we show that the impact of multiple announcements is stronger than that of single news. Our results suggest that the impact of foreign macroeconomic announcements goes beyond the impact of the foreign stock markets on Central and Eastern European indices. We also discuss the implications of the findings for financial stability in the three emerging European markets.     

Volatility spillovers and the effect of news announcements

We examine the effect of US and European news announcements on the spillover of volatility across US and European stock markets. Using synchronously observed international implied volatility indices at a daily frequency, we find significant spillovers of implied volatility between US and European markets as well as within European markets. We observe a stark contrast in the effect of scheduled versus unscheduled news releases. Scheduled (unscheduled) news releases resolve (create) information uncertainty, leading to a decrease (increase) in implied volatility. Nevertheless, news announcements do not fully explain the volatility spillovers, although they do affect the magnitude of volatility spillovers. Our results are robust to extreme market events such as the recent financial crisis and provide evidence of volatility contagion across markets.     

The impact of economic news on bond prices: Evidence from the MTS platform

Although there is an extensive literature on the impact of macroeconomic announcements on asset prices, the bond market has received less attention than the foreign exchange and equity markets, even less if we consider the European market. This paper uses high-frequency intra-day data over a three-year period to investigate the impact of regularly scheduled macroeconomic news and monetary policy announcements on the returns of the Italian government bond market, the largest one in the Euro-zone. With respect to the previous papers, we use a much broader set of announcements, 68, and a relatively novel dataset (MTS). We find that 25 news have a significant impact on bond returns and that almost all announcements are incorporated into prices within 20 min from the release.     

Information arrivals and intraday exchange rate volatility

This paper investigates the link between information arrivals and intraday DEM/$ volatility. Information arrivals are measured by the numbers of news items that appeared in the Reuters News Service. We separate news stories into different categories and find that total headline news counts, US and German macroeconomic news and German Bundesbank monetary policy news all have a significant impact on intraday DEM/$ volatility. The larger quantitative effects of the German Bundesbank monetary policy news and US macroeconomic news at 15-min intervals are consistent with the findings of a two-stage adjustment process of public information arrivals [Fleming and Remolona, J. Finance (1999) 1901]. Our results suggest that the persistent of intraday exchange rate volatility set off by public information is extended by traders’ private information about 15 min later. The conclusions are obtained from ARCH models that incorporate intraday seasonal volatility terms.     

Macroeconomic fundamentals, price discovery, and volatility dynamics in emerging bond markets

This study characterizes volatility dynamics in external emerging bond markets and examines how prices and volatility respond to macroeconomic news. As in mature bond markets, surprises about macroeconomic conditions in emerging markets are found to affect both conditional returns and volatility of external bonds, with the effects on volatility being more pronounced and longer lasting than those on prices. Yet the process of information absorption tends to be more drawn-out than in mature bond markets. Global and regional macroeconomic news is at least as important as local news for both price and volatility dynamics.     

Exchange rate volatility response to macroeconomic news during the global financial crisis

We investigate the volatility reaction to macroeconomic news in major currency markets during the recent global financial crisis. We first present an alternative method for determining the changes in economic states by endogenously estimating crisis thresholds. Second, we assess which macroeconomic indicator gave the earliest warning signal for the upcoming contraction. Third, we investigate whether there is a systematic change in the volatility reaction of exchange rates to news during the crisis period. We find that the estimated logistic transition function based on the housing starts data exhibits the earliest warning signal compared to other indicators. Our results suggest that although volatility response to most news indicators is larger in expansion, currency market reaction to new home sales and Fed funds rate news is larger in the crisis period. We attribute this finding to the context-specific relevance of the housing and credit sectors in the evolution of the global financial crisis.     

Stock prices, news, and business conditions

Previous research finds that fundamental macroeconomic newshas little effect on stock prices. We show that after allowingfor different stages of the business cycle, a stronger relationshipbetween stock prices and news is evident. In addition to stockprices, we examine the effect of real activity news on proxiesfor expected cashflows and equity discount rates. We find thatwhen the economy is strong the stock market responds negativelyto news about bigger real economic activity. This negative relationis caused by the larger increase in discount rates relativeto expected cashflows.     

Impact of macroeconomic news on metal futures

This paper uses intra-day data for the period 2002 through 2008 to examine the intensity, direction, and speed of impact of US macroeconomic news announcements on the return, volatility and trading volume of three important commodities - gold, silver and copper futures. We find that the response of metal futures to economic news surprises is both swift and significant, with the 8:30 am set of announcements - in particular, nonfarm payrolls and durable goods orders - having the largest impact. Furthermore, announcements that reflect an unexpected improvement in the economy tend to have a negative impact on gold and silver prices; however, they tend to have a positive effect on copper prices. In comparison, realized volatility and volume for all three metals are positively influenced by economic news. Finally, there is evidence that several news announcements exert an asymmetric impact on market activity variables.     

Do external political pressures affect the Renminbi exchange rate?

This paper investigates whether external political pressure for faster Renminbi appreciation affects both the daily returns and the conditional volatility of the Renminbi central parity rate. We construct several political pressure indicators pertaining to the Renminbi exchange rate, with a special emphasis on the US pressure, to test the hypothesis. After controlling for Chinese macroeconomic surprise news, we find that US and non-US political pressure does not have a significant influence on Renminbi's daily returns. However, evidence suggests that political pressures, and especially those from the US, have statistically significant impacts on the conditional volatility of the Renminbi. Furthermore, we conduct the same exercise on the 12-month Renminbi non-deliverable forward rate. We find that the non-deliverable forward market is highly responsive to macroeconomic surprise news and there is some evidence that Sino-US bilateral meetings affect the conditional volatility of the Renminbi non-deliverable forward rate.     

Comparing the Impact of News: A Tale of Three Health Care Sectors

Abstract:   This paper examines the impact of news on the volatility of equity returns in three sectors of the health care industry – health care service providers, producers of drugs and supplies, and third‐party payors. The news impact is found to be asymmetric in that bad news (i.e., a negative shock) has a significantly greater effect on volatility than good news. Intra‐industry differences in health care equity market performance are documented and are consistent with the fundamental attributes of these sectors including the degree of price and cost pressures facing firms, the physical capital requirements of firms, the search behavior of health care customers, and the presence of alternative market opportunities.     

The impact of macroeconomic news on quote adjustments, noise, and informational volatility

We study the impact of the arrival of macroeconomic news on the informational and noise-driven components in high-frequency quote processes and their conditional variances. We decompose bid and ask returns into a common (“efficient return”) factor and two market-side-specific components capturing market microstructure effects. The corresponding variance components reflect information-driven and noise-induced volatilities. We find that all volatility components reveal distinct dynamics and are positively influenced by news. The proportion of noise-induced variances is highest before announcements and significantly declines thereafter. Moreover, news-affected responses in all volatility components are influenced by order flow imbalances.
