The current research is to provide an applicable and suitable model for the provision of stock portfolio management based on market timing approach and prioritization of components and model extraction using structural equations. This research aims to create a model to achieve and create the necessary platforms for creating a market timing approach in order to drive the superior components to extract the model using structural equations in the direction of stock portfolio management. Portfolio management is one of the most important areas of financial research for researchers, and choosing a portfolio with a high rate of return and controlled risk is one of the topics that has attracted the attention of many researchers. The methodology used in this research is qualitative. in which the foundation data grand theory method is used. that by using the opinions of subject matter experts and interviewing 10 experts in this field and using the snowball method until reaching the theoretical saturation stage in order to identify the effective factors in formulating the model and model of the research by using open coding, central and selective has been discussed. In the end, the results of this research have led to the presentation of a model for stock portfolio management based on the market timing approach. From the results of the current research, the most important activities of the first priority are the results obtained in the sectors such as: design of financial intermediary institutions, investor expectation level, transparency in stock supply, technical purchase of shares, improvement of the financial strength of the joint-stock company, in the direction of portfolio management. Stocks based on market timing approach are exploited.
