I want to know something, For Example a company xyz owns many companies, xyz is parent company of many companies basically a conglomerate and now that parent company xyz wants to buy public listed company called airtel and after buying new name will be kept so how is this done? Can anyone buy public listed companies? what is the process?
You cannot Entirely but listed companies cause it's already gone public. You can earn a major chunk of stake from the company. By doing that you will be one among the bod.
