This paper aims at inspecting the existence of rational speculative bubbles in the Amman Stock Exchange market (ASE) along two sample periods, the first from 2004 to 2009, and the second from 2010 to 2018. The paper uses three different quantitative approaches to analyse the returns for ASE index over the selected sample periods. The first approach is the descriptive statistics, the second one is the explosiveness test approach, and the third one is the duration dependence test approach. The paper found evidence for the existence of a rational speculative bubble in ASE returns for the first sample period inspected and based on the three different approaches. This paper represents a contribution toward establishing an effective early warning system for predicting and mitigating financial crises. The paper represents a good contribution to improve the investment environment in Jordan.
