Download or read book How Lead Lag Correlations Affect the Intraday Pattern of Collective Stock Dynamics written by Chester Curme and published by . This book was released on 2019 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Properly estimating correlations and understanding how they change under different economic conditions plays a key role in asset pricing models, risk management, and many econometric models. In this paper we introduce a robust framework to identify a meaningful correlation relationship, address different types of correlations and their interplay, and address correlations across different time scales. First, we present a methodological framework to estimate synchronous, lagged, and autocorrelations for stock price return time series, and validate their statistical significance across different time horizons. Second, we explore the interplay between these different co-movement relationships, using a model to uncouple the factors contributing to the intraday pattern of contemporaneous correlations, including volatility, autocorrelations and lagged cross-correlations. Third, we use the methodological framework to investigate correlations between stocks traded on the New York Stock Exchange in the periods 2001-03 and 2011-13, and provide insights on how correlations and their dynamics have changed over time.

Download or read book Market Capitalization Cross Correlations the Lead Lag Structure and Microstructure Effects in the Indian Stock Market written by Sunil S. Poshakwale and published by . This book was released on 2002 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lead/lag relationship between large and small cap firms is investigated by using a number of Indian equity index series that differ in their market capitalisation characteristics. Large cap indices are found to lead small cap indices and to have higher speeds of adjustment towards intrinsic values. Pure thin trading effects and a thin trading/adjustment interaction effect are found to make significant contributions to the lead/lag effect. The intrinsic value processes themselves, are found to be characterised by a small degree of overreaction.
Download or read book Do Lead Lag Effects Affect Derivative Pricing written by Olaf Korn and published by . This book was released on 2002 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we extend an analysis by Lo and Wang (1995), who showed that predictability of asset returns affects derivatives prices through its impact on instantaneous volatility. We investigate how the whole instantaneous variance-covariance matrix of two assets returns is affected by typical lead-lag patterns. A close link between the cross-autocorrelations of finite holding-period returns and the instantaneous correlation is derived, which implies a strong impact of lead-lag patterns on correlation dependent derivatives. We provide simple adjustments for lead-lag effects and apply our results to the valuation of stock option plans.
Download or read book Intraday Lead Lag Relationship Between Stock Index and Stock Index Futures Markets written by Ersan Ersoy and published by . This book was released on 2016 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: In perfectly frictionless and rational markets, spot markets and futures markets should simultaneously reflect new information. However, due to market imperfections, one of these markets may reflect information faster than the other and therefore may lead to the other. This study examines the lead-lag relationship between stock index and stock index futures, in terms of both price and volatility, by using 5 minute data over 2007-2010 period. The findings of this study indicate that a stable long-term relationship between Turkish stock index and stock index futures exists, however stock index futures do not lead stock index and there is a two way interaction between them. Therefore either of the markets is dominant over the other one in the price formation process.
Download or read book Statistical Properties Dynamic Conditional Correlation Scaling Analysis of High Frequency Intraday Stock Returns written by Thomas Chinan Chiang and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates statistical properties of high-frequency intraday stock returns across various frequencies. Both time series and panel data are employed to explore probability distribution properties, autocorrelations, dynamic conditional correlations, and scaling analysis in the Dow Jones Industrial Average (DJIA) and the NASDAQ intraday returns across 10-minute, 30-monute, 60-minute, 120-minute, and 390-minute frequencies from August 1, 1997, to December 31, 2003. The evidence shows that all of the statistical estimates are highly influenced by the opening returns that contain overnight and non-regular information. The stylized fact of high opening returns generates significant negative (in DJIA) and positive (in NASDAQ) autocorrelations. After excluding the opening intervals, DJIA exhibits a pattern similar to a random walk. While examining the AR(1)-GARCH (1, 1) pattern across both time and frequency variants, we find consistent negative AR(1) at 10-minute and 30-minute frequencies in the DJIA, positive AR(1) in the NASDAQ intraday returns, and no obvious pattern beyond the 30-minute intraday return series. By examining the dynamic conditional correlation coefficients between the DJIA and the NASDAQ at different frequencies, we find that the correlations are positive and fluctuate mainly in the range of 0.6 to 0.8. The variance of the correlation coefficients has been declining and appears to be stable for the post-2001 period. We then check the conditions for a stable Levy distribution and find both the DJIA and the NASDAQ can converge to their systematic equilibriums after shocks, implying both systems are characterized by a self-stabilizing mechanism.

This book was released on 2011-04-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goal of the book is to present the ideas and research findings of active researchers from various communities (physicists, economists, mathematicians, financial engineers) working in the field of "Econophysics", who have undertaken the task of modelling and analyzing order-driven markets. Of primary interest in these studies are the mechanisms leading to the statistical regularities ("stylized facts") of price statistics. Results pertaining to other important issues such as market impact, the profitability of trading strategies, or mathematical models for microstructure effects, are also presented. Several leading researchers in these fields report on their recent work and also review the contemporary literature. Some historical perspectives, comments and debates on recent issues in Econophysics research are also included.

Henriksson, Chief Investment Officer, Advanced Portfolio Management "Quants"--those who design and implement mathematical models for the pricing of derivatives, assessment of risk, or prediction of market movements--are the backbone of today's investment industry. As the greater volatility of current financial markets has driven investors to seek shelter from increasing uncertainty, the quant revolution has given people the opportunity to avoid unwanted financial risk by literally trading it away, or more specifically, paying someone else to take on the unwanted risk. How I Became a Quant reveals the faces behind the quant revolution, offering you?the?chance to learn firsthand what it's like to be a?quant today. In this fascinating collection of Wall Street war stories, more than two dozen quants detail their roots, roles, and contributions, explaining what they do and how they do it, as well as outlining the sometimes unexpected paths they have followed from the halls of academia to the front lines of an investment revolution.
