{"title":"Estimating the Intensity of News Based on Trade Data","authors":"M.

With the support of a microstructure model we are able to derive a simple formula that, based only on trade data, estimates the likelihood of having news for any given tradable asset in a particular time period. The formula can be easily implemented and takes just one input, the probability of a zero trade price difference conditional on the incoming of consecutive same sign trades. In the empirical part of the paper we investigate the properties of this proposed estimator of news intensity for twenty stocks from the Brazilian equity market, covering two full years from 2010 to 2012. The results are very encouraging and consistent across assets. First we find that the strength of news have a common component across all assets. We attribute that to the fact that the incoming of new information regarding the Brazilian economy will affect all stocks. We also see that the likelihood of news is strongly and positively related to volatility of price differences and negatively related to trade volume. The first can be explained by the fact that volatility is a bi-product of news and the second by the presence of traders avoiding the disclosure of private information by trading smaller volumes. In the empirical section we are also able to show that the intensity of news has a intraday pattern, with higher values at the beginning of the trading day and lower values at the end. This result is consistent with the view that the beginning of the trading day is the time when accumulated overnight information reaches the market, therefore increasing news intensity.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133894581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Statistics from the World Bureau of Metal Statistics (2012) reveal that global refined copper consumption reached over 19.5 million metric tonnes in 2011, with China accounting for 40% of the total. Between 2000 and 2011, Chinese demand grew by 13.5% each year, five times faster than the world average. Much of this growth was derived from the power generation sector, which now makes up 46% of total end-use demand in China, followed by household appliances and transportation. Over the last decade, this industrial metal’s cash price has risen from USD 1,800 per metric tonne to the current USD 8,000, attracting the attention of both institutional and retail investors. Until recently, the main vehicles for investing in the copper market have been equities and futures contracts. However, investors can now gain direct exposure to copper by choosing products that are linked to the newly-launched SP An introduction to the SP The practical applications of the index; How copper returns are related to economic activity; The inflation properties of the index; Whether an allocation to the S&P GSCI Cash Copper index has historically offered any diversification benefits.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130515957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that the correlated version of maximal affine models for a single commodity is no longer maximal for multiple commodities. In the maximal model, the convenience yield of a certain commodity could depend on the prices of other commodities, which is consistent with the structural model in our companion paper Casassus, Liu, and Tang (2012). Furthermore, the maximal model can offer a new feedback (error-correction) effect among commodity prices, which is consistent with many empirical studies.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132305888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the increased investment in gold for speculative or hedging purposes has changed the safe haven property. We demonstrate theoretically and empirically that investor behaviour has the potential to destroy the safe haven property of gold. The results suggest that an asset cannot be both an investment asset and an effective safe haven asset. This finding has important implications for financial stability since assets are more likely to exhibit excess comovement and volatility in the absence of a safe haven.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128259435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The theory of storage provides the theoretical reference for the analysis. Our first result is to find that the series have widely different properties which reflect the speedier diffusion of information in the markets today. This emerges both in the order of autocorrelation of the VECMs used to analyze the dynamics of the spot and futures returns and in the structure of the GARCH parameterization. Our second finding is to show that, based on full sample correlations, the theory of storage seems to capture the dynamics of data with the exception of historical tin. Rolling correlations, however, qualify this result and show that dynamic correlation for historical tin largely corroborate the theory of reference while recent inroads of financial agents in commodity markets seem to have affected the cotton market, giving prominence to financial risk factors.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114500054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their innovative line of business initially seemed to promise considerable future earnings. As shown by two powerful bubble tests, the positive sentiment for renewable energy stocks even led to explosive price behavior in the mid-2000s. However, intense sector competition and the economic downturn following the global financial crisis erased profit margins to a large extent. As a result, the former fad stocks have recently turned into losers, loading negatively on price momentum and delivering significantly negative Carhart four-factor alphas. The radical shift in Germany's energy policy following the 2011 Fukushima nuclear disaster in Japan could thus only temporarily halt the continuing decline in alternative energy stock prices.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126898006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six different tests for detecting nonlinearity were employed and the statistics were estimated using both the asymptotic theory and the bootstrap. The analysis of results reveals that there is a consensus in favour of nonlinearity for Metal and Energy indices even after removing linear serial correlations from the data, hence, contradicting the unpredictable criterion of weak-form efficient market hypothesis. Further the results from additional BDS test on the standardised AR(P)-GARCH(1,1) residuals imply that conditional heteroskedasticity is the main source of nonlinearity in metal indices and could be captured by the ARCH-type models. On the other hand in case of energy indices results indicate non-linear dependence of an unknown form in the data. The results have important implications on the earlier work on Indian commodity derivative markets which have relied on conventional statistical techniques which may have lead to biased and highly misleading results.","PeriodicalId":423680,"journal":{"name":"ERN: Econometric Studies of Commodity Markets (Topic)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133911845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
