This paper studies volatility characteristics of the Indian CNX midcap index and contrasts with the large cap Nifty. An EGARCH model is fitted to daily returns for 2010 and is subjected to an out-of-sample back test. The study finds differences in volatility behavior of the indices. The Midcap...

Accurately forecasting volatility is key in many financial applications. In this study, I suggest that individuals gather information online before implementing their trading decisions. In periods of higher investor concern, online information seeking intensifies. By analysing Google search data...

We work in the Uncertain Volatility Model setting of Avellaneda, Levy, Paras [1] and Lyons [10] (cf. also [11]). We first look at European options in a market with no interest rate and focus on theextreme case where the volatility has a lower bound but no upper bound. We show that the smallest...

This paper examines time-varying stock price and volatility dynamics of constituent industry sector indices in the Shanghai Stock Exchange. It finds that market beta risk is priced in the time-series movements of stock prices and responds positively to rises in non-diversifiable risk. The asset...

In this paper, we investigate the dynamic response of stock market volatility to changes in monetary policy. Using a vector autoregressive model, our findings reveal a significant and asymmetric response of stock returns and volatility to monetary policy shocks. Although the increase in the...

The Black’s leverage effect hypothesis postulates that a negative stock return innovation increases the financial leverage of a firm since the value of equity decreases at a given level of debt, which, in turn, creates a higher equity return volatility in the future. The paper is aimed at...

All too often, measuring statistical dependencies between financial time series is reduced to a linear correlation coefficient. However, this may not capture all facets of reality. This paper studies empirical dependencies of daily stock returns by their pairwise copulas. We investigate in...

Unlike the existing literature on value and growth investing, this paper takes a different point of view by conducting a "between-markets analysis." First of all, it asks whether the value premium also exists on a country level, in the sense that country indexes that are undervalued consistently...

This paper presents a quantum harmonic oscillator model of price fluctuations in a stock market. The model builds on a previously-published quantum model of supply and demand, and is compared with other existing quantum models of stock markets, including quantum harmonic oscillator, square-well,...

Density forecasts have become quite important in economics and finance. For example, such forecasts play a central role in modern financial risk management techniques like Value at Risk. This paper suggests a regression based density forecast evaluation framework as a simple alternative to other...
