This study is set out to model and forecast the cryptocurrency market by concentrating on several stylized features of cryptocurrencies. The results of this study assert the presence of an inherently nonlinear mean-reverting process, leading to the presence of asymmetry in the considered return series. Consequently, nonlinear GARCH-type models taking into account distributions of innovations that capture skewness, kurtosis and heavy tails constitute excellent tools for modelling returns in cryptocurrencies. Finally, it is found that, given the high volatility dynamics present in all cryptocurrencies, correct forecasting could help investors to assess the unique risk-return characteristics of a cryptocurrency, thus helping them to allocate their capital.

This paper examines four European equity portfolios sorted by size, book-to-market (B/M) ratios, operating profitability, investment, and momentum by using Markov switching models with high and low volatility regimes. Our empirical analyses derive the following interesting findings. First, in four European equity portfolios, the smallest and the strongest momentum portfolio yields the highest return. In addition, the second smallest and the highest B/M portfolio, the second smallest and the highest operating profitability portfolio, and the second smallest and the second lowest investment portfolio also yield higher returns than the overall equity market in Europe. Further, our analyses using Markov switching models also reveal that for all the four European equity portfolios, the higher returns are obtained not in high volatility regimes but in low volatility regimes, and this evidence is against the assumption of risk-return trade off advocated in standard finance theory. Finally, our Markov switching analyses also suggest that for all the four European portfolios, staying probabilities in the same regimes are high and switching probabilities between two different regimes are generally low. In particular, staying probabilities in low volatility regimes are rather high, thus, all the four European equity portfolios yield high returns very stably by staying high return regimes.

<div><p><em>The objective of this paper is to investigate the presence of low volatility anomaly in Indian stock Market. Anomaly occurs due to the deviation in normal behavior of stocks with respect to risk-return relationship as suggested by CAPM theory. The low volatility anomaly means that portfolio of low volatility stocks provides better returns than the portfolio of high volatility stocks. The anomaly under study is one of the most common technical anomalies detected in various International markets but very few studies are there in Indian context. CAPM theory suggest that there is direct relationship between risk &amp; return but various empirical studies finds that portfolio of low volatility stocks outperforms portfolio of high volatility stocks. In this study, returns of volatility sorted portfolios are used to analyze the low volatility anomaly. The study uses constituent stocks of S&amp;P CNX 100 index of NSE. The data is taken from period January 2001 to December 2014.  The results of this study did not found   any significant low volatility anomaly in India rather results are supporting the CAPM model and thus found that high volatility quintile gives high returns in India and vice-versa.</em></p></div>

This study examines a risk/return mismatch of the MSCI China Index, which has offered investors low returns and high volatility, yet remains a favorite within the global investors' portfolio. The paper suggests several insights, both from behavioral and traditional finance perspectives, to explain this mismatch. An international risk decomposition model is applied to separate the total risk of China's index return into global systematic risks, regional systematic risks and country specific risks. It suggests the index's lower than average systematic risk might be one of the explanations for its risk/return mismatch. The study also finds that the China Index's systematic risks, both global and regional, have been increasing, but more so at the global level.

We study the tail behavior of discounted aggregate claims in a continuous-time renewal model. For the case of Pareto-type claims, we establish a tail asymptotic formula, which holds uniformly in time.

Any new information about the economy is transmitted fast and it may influence the financial markets, positively or negatively. The present study used GARCH (1, 1) and EGARCH models, to investigate the volatility of Indian banking sectors indices, namely, Nifty PSU Index and Nifty Private Bank Index of NSE India Ltd. The result of the study confirmed that the high volatility was found in both the bank indices. At the same time, negative information about Indian economics did affect the PSU and Private Bank Sector indices during the study period. Finally, the study concluded that bad news travels fast and it increased volatility more than good. Hence the Government should give more information and awareness programme to the people before the implementation of any economic policy.

This article sets up a single period value maximization model for the firm based on stochastic end-of-period cash inflows, stochastic bankruptcy costs and taxes based on income rather than wealth. The risk-return trade-off is captured in the Capital Asset Pricing Model. Thus, the model also assumes a perfect capital market and market equilibrium. The model establishes the existence of a unique optimal financial leverage at which the firm value is maximized, this leverage being less than the maximum debt capacity of the firm.
