AB - In the stock market, the investor's investment sentiment has a serious impact on other individual 
investors. In the past, people used the infectious disease transmission model to conduct in-depth research on 
the  spread  of  various  diseases.  In  this  paper,  we  will  use  the  infectious  disease  model.  Based  on  and 
improved, the time delay caused by information delay and the saturation rate due to people's limited social 
ability are added to the homogenous network, which makes the established model more realistic. First,  we 
establish the goal of emotional communication. The positive sentiment-based SIR propagation model is then 
proved by a series of mathematical methods to the local stability and global stability of the model. Finally, 
we use the numerical simulation study to verify the results we obtained, and the results show that: When the 
number of people stays in equilibrium and the information lagging factors are kept under control, the market 
will remain stable.
