There are fifty thousand plus companies existing in India. There are around five thousand plus companies which are listed in National Stock Exchange. So, it is a complicated aspect to the investor to select a right company for the investment purpose. There are more than fifty subjects in commerce. It is not like History, Economics or Chemistry subject. In these subjects, it is very easy to select a subject for getting mastery. Because, if we take History for example, we study Karnataka history, Indian history, world history. Day by day, we will get expertness in the same subject history by studying vertically. But in commerce stream, we study Financial Accounting, Cost Accounting, Management Accounting, Financial Management, Marketing Management, Human Resources Management, Organizational Behavior, Business Law etc. So, in commerce stream, it is very difficult to get mastery or expertness. That is why commerce is called as Jack of all but Master of none. These problems can be overcome with the help of narrow downing concept. The scholar in commerce field can select Finance or Marketing or Human Resource Management for study and publication and thereby study can be simplified. Similarly, investor can apply filter concept in Tickertape application which is free software available to all.
