Over the years, various models have been proposed to evaluate trading halts and explain them. These models have been evaluated in different ways and the results of the tests show that the factors proposed in these models alone cannot explain the volatility of trading in the stock exchange. For this reason, the idea of combining various influential factors in the capital market to clearly explain the suspension of transactions plays an important role in the process of discovering accurate price identification, improving asset valuation and increasing information efficiency. Therefore, the purpose of the current research is to investigate the moderating effect of the life cycle on the model of the magnetism factor and stock stop in the Tehran Stock Exchange. The research is based on the applied purpose, based on descriptive survey data collection method, and based on the type of consolidated data. In this research, to test the relative effectiveness of the symbol stop and the price fluctuation limit, the changes in the average from the period before the event to the period after the event have been investigated. 500 trading breaks and 849 price fluctuation limits related to 120 selected companies have been investigated by elimination sampling method during the period of 2020-2023. The results of the research show that the magnet effect has an effect on the suspension of transactions. Also, there is a positive and significant relationship between the effect of magnetism and stopping stocks with the moderating effect of the life cycle. And finally, stocks stop in the maturity stage more than the growth and decline stages.
