Financial modeling in developing markets requires dynamic and complex algorithms, which enable investors to estimate extremes in the returns arising from the chaotic characteristics of those markets. In this research paper, the value-at-risk (VaR) of a portfolio consists of Bombay Stock Exchange...

Long-term memory effect in stock prices might be captured, if any, with alternative models. Though Geweke and Porter-Hudak (1983) test model the long memory with the OLS estimator, a new approach based on wavelets analysis provide WOLS estimator for the memory effect. This article examines the...

Model risk in the estimation of value-at-risk is a challenging threat for the success of any financial investments. The degree of the model risk increases when the estimation process is constructed with a portfolio in the emerging markets. The proper model should both provide flexible joint...
