In this paper we propose a new bootstrap, or Monte-Carlo, approach to such problems. Traditional bootstrap methods in this context are based on fitting a process chosen from a wide but relatively conventional range of discrete time series models, including autoregressions, moving averages,...

The study investigates the relationships between exchange rate and stock price over the period January 2007 to March 2014. Index National Stock Exchange, namely, NIFTY is used as indicator of stock price. Johansen's co-integration and Granger causality test have been applied to explore the...

Indices providing cost-efficient passive exposure to factors such as value, growth, momentum, small size or low volatility, and other non-cap-weighted indices such as high dividend yield, high quality, high and low beta or equal-weighted indices, are well known and widely used in practice as...

Benoît Mandelbrot, the father of Fractal Geometry, developed a multifractal model for describing price changes. Despite the commonly used models, such as the Brownian motion, the Mutifractal Model of Asset Return (MMAR) takes into account scale-consistency, long-range dependence and heavy...

This paper proposes a threshold stochastic conditional duration (SCD) model for financial data at the transaction level. In addition to assuming that the innovations of the duration process follow a threshold distribution with positive support, we also assume that the latent first-order...

We discuss the finding that cross-sectional characteristic based models have yielded portfolios with higher excess monthly returns but lower risk than their arbitrage pricing theory counterparts in an analysis of equity returns of stocks listed on the JSE. Under the assumption of general...

This paper extends a stochastic conditional duration (SCD) model for financial transaction data to allow for correlation between error processes or innovations of observed duration process and latent log duration process with the aim of improving the statistical fit of the model. Suitable...

This study investigates the existence of chaos on the Johannesburg Stock Exchange (JSE) and studies three indices namely the FTSE/JSE All Share, FTSE/JSE Top 40 and FTSE/JSE Small Cap. Building upon the Fractal Market Hypothesis to provide evidence on the behavior of returns time series of the...

Given that changes in oil prices influence the observable factors in GCC economies, this paper shows unobservable speculative factors that drive short-term stock market returns in Saudi and Bahrain markets.1 For other GCC markets, such as Dubai, Abu-Dhabi, and Muscat, oil price uncertainty and...
