Contributions to modelling correlations in financial econometrics
Scott, Ayesha T. (2016) Contributions to modelling correlations in financial econometrics. PhD thesis, Queensland University of Technology.
Modelling the correlations between financial asset returns is important for portfolio management and this thesis assesses a number of correlation models to provide insights into the best way to handle large portfolios of assets. It also outlines key features of stock correlation dynamics evident over the trading day and presents a model to capture this intraday pattern. Indeed, very little work exists on the dynamics of correlations during the trading day despite research into modelling intraday volatilities gaining momentum. These findings further the understanding of correlation dynamics, both in large portfolios as well as in returns sampled at high frequencies during market trading hours.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
