Proper selection of investment projects in the capital market, including stock exchanges, is one of the most important issues of the day.

An appropriate choice can help ensure investor and increase market efficiency. In most cases, there are beneficial investment projects but there is no access to financial resources for them.

Therefore, in planning investment, in addition to evaluating and choosing projects individually, attention should be paid to the interaction and interaction effects of the projects. In other words, we need to take this approach to the choice of plans that do not consider it as an activity that is in void and apart from other goals and decisions, but all the important and important issues involved in choosing a project.
