Abstract
This paper empirically examines the effect of weekly options introduction on the benchmark index of Indian stock market, NIFTY50. The paper evaluates the possible stabilizing or destabilizing nature of impact on underlying volatility focusing on the relation between information and volatility using GARCH framework. The results indicate that the onset of weekly index options has improved the information assimilation and reduced the persistence of old information on volatility. Further, similar changes are not evident on a control index, NIFTY NEXT50. Overall, the results indicate an increase in market efficiency with weekly index options trading.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article.
