This paper develops a new test, the trinomial test, for pairwise ordinal data samples to improve the power of the sign test by modifying its treatment of zero di®erences between observations, thereby increasing the use of sample information. Simulations demonstrate the power superiority of the...

This paper examines risk-averse and risk-seeking investor preferences for oil spot and futures prices by using the mean-variance (MV) criterion and stochastic dominance (SD) approach. The MV findings cannot distinguish between the preferences of spot and futures markets. However, the SD tests...

This paper develops the stochastic dominance (SD) tests for risk seekers. We find both MV criterion and CAPM measures unable to draw any conclusive preference between the returns but our SD results show that spot dominates futures in the downside risk while futures dominate spot in the upside...

This paper features a statistical analysis of the monthly three factor Fama/French return series. We apply rolling OLS regressions to explore the relationship between the 3 factors, using monthly data from July 1926 to June 2018, that are available on Ken French's website. The results suggest...

This paper examines the market efficiency of oil spot and futures prices by using both mean-variance (MV) and stochastic dominance (SD) approaches. As there is no evidence of any MV and SD relationship between oil spot and futures, we conclude: there is no arbitrage opportunity between these two...
