The Oxmetrics ۷ software is used to investigate the existence of multiple bubbles and research objective. The results of the study of the state space switches confirm the bubble of the capital market in Iran during four periods in the research domain. The life span of the first speculative bubble is ۲ months from October to November ۲۰۱۱, the second is ۸ months from March to October ۲۰۱۳, the third is ۳ months from December ۲۰۱۵ to February ۲۰۱۶, and the fourth period of bubble is ۵ months from August to December ۲۰۱۷.
