Estimating Stock Return Volatility in Indian and Chinese Stock Market


Book Description

Investors step into the stock market with the objective of earning smart returns on their investments. The stock market can help in realising these goals of the investors, however, all investments are subject to risks. The origin of the risk is the uncertainty of realising the desired returns on the investment. This aspect is known as risk of the investment. This paper aims to search the best model to estimate and forecast volatility of Indian and Chinese stock market. The data for the paper is related to the two main indices of Indian Stock Market namely, SENSEX and NIFTY and two indices of Chinese stock market, namely, Shenzhen composite index and Shanghai composite index for the period July 2003 to June 2013. We applied symmetrical as well as asymmetrical GARCH models to the data. Among all the three models i.e. GARCH, EGARCH and TARCH, we found the GARCH (1,1) model as the best model to estimate and forecast the volatility of Chinese stock market for both the daily and weekly return series. For the Indian stock market, the recommended volatility estimation and forecasting model is EGARCH model that captures the leverage effect. We did not find volatility clustering and leverage effect for the monthly return series for both Indian and Chinese stock market. Thus, it is suggested to use the traditional time invariant volatility models for the monthly return series.

Why Does Return Volatility Differ in Chinese Stock Markets?


Book Description

We estimate a modified mixture of distribution model (Andersen, 1996) to explore the underlying causes of the volatility differences between domestic A shares and foreign B shares listed in Chinese stock markets. Using return and trading volume data for 24 firms as well as value-weighted portfolios constructed, we obtain parameter estimates characterizing the distribution of the underlying news information flows. We find evidence that news enters the A-share market more intensively, is more correlated with A-share trading, and is more persistent for A shares than for B shares. Our cross-sectional test results also indicate that some of the greater return volatility for A-shares is due to variation in firm's profits, firm size, and a substantially larger number of investors leading to a high probability of trading on a given news flow.




INVESTMENT AND DIVERSIFICATION OPPORTUNITIES IN INDIAN AND CHINESE STOCK MARKETS


Book Description

Major findings are; 1) Indian market behave asymmetric and proved leverage effectin all the three periods considered, whereas the Chinese market shows different leverage patterns with reverse asymmetry when crisis is accounted. 2) The trade-off between risk and return varies due to the different state of market. In pre-crisis period both the market evidenced positive risk-return trade off, as expected from the theory however in post-crisis Nifty return is negatively related to its volatility which is contrary to the theory. 3) The conditional volatility persisted for more days in Chinese market than Indian, the HL Calculator shows that Shanghai Composite takes more time to return back to its mean with long lasting impact evidenced in positive shocks, leading to reject the theoretical mechanism behind the asymmetry which says negative shocks increase conditional volatility substantially.

Estimating Volatility Pattern in Stock Markets


Book Description

This paper examines the volatility pattern in Indian stock markets during the time period January 1, 2011 to March 31, 2014 using the daily closing prices of two stock indices, S&P BSE Sensex and CNX Nifty. This paper uses asymmetric GARCH models like Exponential GARCH (EGARCH) and Threshold GARCH (TGARCH to explain the volatility. Considering the minimum values of Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC), TGARCH model is found to be a superior model for return volatility over EGARCH. The findings suggest that there is no volatility persistence as well as leverage effect in the data during the period under consideration.







Stock Returns and Volatility on China's Stock Markets


Book Description

We examine time-series features of stock returns and volatility, as well as the relation between return and volatility in four of China's stock exchanges. Variance-ratio tests reject the hypothesis that stock return follows a random walk. We find evidence of long memory of returns. Application of GARCH and EGARCH models provides strong evidence of time-varying volatility and shows volatility is highly persistent and predictable. The results of GARCH-M do not show any relation between expected returns and expected risk. Daily trading volume used as a proxy for information arrival time has no significant explanatory power for the conditional volatility of daily returns.
