In statistical modelling contexts, the use of one-step-ahead prediction errors for testing hypotheses on the forecasting ability of an assumed model has been widely considered. Quite often, the testing procedure requires independence in a sequence of recursive standardized prediction errors,...

A number of single ARCH model-based methods of predicting volatility are compared to Degiannakis and Xekalaki's (2005) poly-model standardized prediction error criterion (SPEC) algorithm method in terms of profits from trading actual options of the S&P500 index returns. The results show that...

In this article we investigate if stock market returns are related to temperature. Research in behavioural finance shows that lower temperature can lead to aggression, while higher temperature can lead to both apathy and aggression (Cao and Wei, 2005). Evidence from previous studies suggests...
