This study models high and low frequency variation in global equity correlations using a comprehensive sample of 43 countries that includes developed and emerging markets, during the period 1995-2008. These two types of variations are modeled following the semi-parametric Factor-Spline-GARCH...

We model high and low frequency variation in global equity correlations using a sample of 43 countries, including developed and emerging markets during the period 1995-2008. Such variations are characterized by a multifactor asset pricing structure with second-moments dynamics leading to high...

In this paper, we identify long-term prior return patterns in stock returns for Brazil, Russia, India, China, South Korea, and South Africa (BRICKS) markets from January 1993 to February 2008. While Brazil, Russia and South Africa report momentum behavior, India, China and South Korea exhibit...

The paper suggests a nonlinear and multivariate time series model framework that enables the study of simultaneity in returns and in volatilities, as well as asymmetric effects arising from shocks. Using daily data 2000-2006 for the Baltic state stock exchanges and that of Moscow we find...

Momentum strategies have drawn great attention in investment management literature over last two decades. In this paper we examine three important propositions in Indian context (1) Do momentum profits persist for long time periods?, (2) Can these momentum profits be absorbed by risk models?,...

The relationship between risk and expected returns has been investigated extensively in the financial economics literature. Theoretical models generally predict a positive relation between the two. Nevertheless, the empirical findings so far have been inconclusive. Using a generalization of the...

The Chinese version of NASDAQ, ChiNext has gone through three time periods with two different regulation regimes (approval and registration) and three sets of listing day trading restrictions (trading curbs, hard return caps, and no restrictions). We hypothesize that the initial return contains...

This study is an attempt to model the volatility of stock returns in Indian market for the period 1997-2006 using GARCH, TARCH and E-GARCH. Results point out that returns exhibit persistence and volatility clustering in both NSE Nifty and BSE Sensex. Asymmetric volatility effect has been...

This paper studies the impact of international capital flows on asset prices through risk premia. We investigate whether foreign purchases of U.S. Treasury securities significantly contributed to the decline in excess returns on long-term bonds between 1995 and 2008. We run forecasting...

We identify local and global factors across international bond markets that are poorly spanned by the traditional level, slope and curvature factors but have strong forecasting power for future bond excess returns. Local and global factors are jointly significant predictors of bond returns,...
