The paper investigates the issue of behaviour of stock returns in India. A non-parametric variance ratio test is used to examine the issue. Largely the results indicate non-random walk behaviour of Indian stock market. However, the sub-sample analysis of stock returns based on structural breaks...

This paper examines the long-run performance of French initial public offerings (IPOs) carried out between 1991 and 2005. Using various methodologies, we found that IPOs in our sample performed poorly relative to the comparison portfolios over the 1991–2005 horizon in contrast to that reported...

Long run returns of IPO firms’ recommendations in Europe reveal possible conflicts of interest and pressures faced by financial analysts over the 1991-2005 period. Nevertheless, recent European legislations about investment research have led to better long run performance of IPO firms’...

This paper examines the long run performance of French IPOs carried out between 1991 and 2005. By using various methodologies, we find that IPOs in our sample performed negatively relative to comparison portfolios over the 1991-2005 horizon, unlike prior studies applied to French market. This...

This paper addresses the question of the importance of analyst coverage for the long-run returns of IPO firms over the period from 1991 to 2010. In US IPOs, during the one- to five-year horizon, we find a significant long-run abnormal performance by orphans (IPOs without analyst coverage)...

Long memory in variance or volatility refers to a slow hyperbolic decay in auto-correlation functions of the squared or log-squared returns. GARCH models extensively used in empirical analysis do not account for long memory in volatility. The present paper examines the issue of long memory in...

The paper examines the long memory in stock returns of emerging markets. Unlike earlier studies, present study carries out a biased reduced semi-parametric test to detect long memory in mean process and uses diverse and updated data set. The test results finds no strong evidence of long memory...

This paper examines the long-run performance of US IPOs carried out between 1991 and 2010. By using various methodologies, we find that IPOs in our sample performed abnormally relative to comparison portfolios over the 1991-2010 horizon. This abnormal long-run performance is much severe for...

This paper re-examines the issue of mean-reversion in Indian equity market. Unlike earlier studies, the present paper carries out multiple structural breaks test and uses new and disaggregated data set. The study found significant structural breaks in the returns series of all selected indices...

This paper examines the stock return behaviour in two premier Indian stock markets using Chow-Denning multiple variance ratio and Hinich bicorrelation tests. The former test overcomes size distortion of conventional variance ratio test. The latter test is capable of detecting linear and...
