Lead-lag correlationsBootstrap methodStatistically validated networksC55C15G41According to the leading models in modern finance, the presence of intraday lead-lag relationships between financial assets is negligible in efficient markets. With the advance of technology, however, markets have become more ...
Econometric inference on such model provides: (i) a unified statistical test for the presence of lead-lag correlations in the latent price process and for the existence of a multi-asset price formation mechanism; (ii) separate estimation of contemporaneous and lagged dependencies; (iii) an ...

Specifically, a two-dimensional convolutional neural network (2D-CNN) is used to quantify the uncertain lead-lag correlations among RPPs; secondly, a gate mechanism is used to calculate a dynamic adjacency matrix; Finally, a graph attention network (GAT) is used to aggregate the information on...
We examine the contemporaneous correlation as well as the lead–lag relation between trading volume and return volatility in all stocks comprising the Dow ... Ali,F,Darrat,... - 《Journal of Banking & Finance》 被引量: 234发表: 2003年 Intraday Lead-Lag Relationships between the Futures-, ...
We can also normalize the contrast to have an unbiased estimation of the cross correlation function rho for different lags. In theory this function should be a Dirac centered around the lead_lag parameter with ρ(lead_lag) = 0.8 and 0 elsewhere....
Lead-lag effects - trading strategies - contrarian strategies - EGARCH - Cross Correlation Function (CCF)We test for lead-lag effects in the mean and variance among size-sorted portfolios for the UK stock market. We construct three sets of portfolios, namely a set of size-sorted equally-...

We quantify the lead–lag relation based on the cross-correlation function from which two different measures are extracted; the lead–lag ratio (LLR) based on the whole cross-correlation function (Huth and Abergel, 2014), and the lead–lag time (LLT) defined as the point where the absolute...
The relationships between the two variables was analyzed in different time-scales (short, medium and long-term scales) using a wavelet correlation graphical tool. Overall, the studies employing the wavelet analysis observe the lead-lag relationships in an intuitive way as this methodological tool can...
