Is it permissible to use a quantitative model solely for stock purchases if properly researched?

Using a quantitative model for stock purchases can be permissible if the model has been proven effective. This means that substantial research and evidence supporting the model's accuracy and reliability in predicting stock performance have been conducted. Quantitative models often rely on mathematical algorithms and historical data, which can provide a solid foundation for sound investment decisions if the model has been validated through rigorous testing and performance metrics.

The emphasis on using a proven model underscores the importance of reliability in investment strategies. If the model has demonstrated consistent success in various market conditions, it can be a valuable tool for making informed investment decisions. Proper research includes understanding the underlying assumptions of the model, the data used for analysis, and the potential market conditions it was tested against. This approach allows investors to take advantage of quantitative strategies while maintaining a level of confidence in the outcomes they can expect from those strategies.
