The fractal theory was first proposed by Mandelbrot in the 1970s and later it was carried by Kantelhardt in mid-2000 and introduced Multi-fractal de-trended fluctuation analysis (MFDFA). The MFDFA uses different time series data to find statistical characteristics efficiently. This study uses...

We scrutinize China, Hong Kong, Indonesia, Japan, Malaysia, Philippines, South Korea, Taiwan, and Thailand for the presence of rational bubbles by employing several tests on a large dataset that includes three bubble episodes. We also convert most tests into recursive to overcome structural...

The proliferation of algorithmic high-frequency trading in financial markets has also led to an increase in new types of fraudulent activity. Since the flash-crash of 2010 first brought it to popular prominence, layering or spoofing fraud has become a major concern for financial regulators...

Consider using the simple moving average (MA) rule of Gartley (1935) to determine when to buy stocks, and when to sell them and switch to the risk-free rate. In comparison, how might the performance be affected if the frequency is changed to the use of MA calculations? The empirical results show...

Theoretical credit risk models a la Merton (1974) predict a non-linear negative link between a firm's default likelihood and asset value. This motivates us to propose a flexible empirical Markov-switching bivariate copula that allows for distinct time-varying dependence between credit default...

We re-examine the presence of rational speculative bubbles in the Singaporean and Indonesian stock markets in light of contradictory results in the literature. We employ a mix of descriptive statistics, explosiveness tests and duration dependence tests for an expanded dataset from 1970 to 2013...

Purpose: The purpose of this paper is to re-examine the presence of rational speculative bubbles in the Malaysian stock market in light of contradictory results presented in previous studies. Design/methodology/approach: We use descriptive statistics, explosiveness tests and the duration...

Stock recommendations based on technical analysis have been evaluated by researchers in terms of the abnormal excess returns generated compared to some benchmark return. Here, instead of looking at the magnitude of excess returns, we study the liquidity of trading strategies based on analyst...

We empirically investigate the effect of option listing on the underlying stock efficiency by examining the stock price duration dynamic and the informed trading activity around option listing. We use univariate tests and extended Log-ACD models that account for liquidity. Despite a significant...

Using density forecast evaluation techniques we compare the predictive performance of econometric specifications that have been developed for modeling duration processes in intra-day financial markets. The model portfolio encompasses various variants of the Autoregressive Conditional Duration...
