Why would a public company not initiate secondary stock offerings more often?
What prevents a company from doing secondary public stock offerings on regular basis? The primary goal of a company doing secondary public offering is to raise more funds, that can be utilized for funding the business. If no funding is needed [i.e. company has sufficient funds, or no expansion plans], this funding creates a drag and existing shareholder including promoters loose value. For example with the current 100 invested, the company is able to generate say 125 [25 as profit]. If additional 100 is taken as secondary public offering, then with 200, the company should mark around 250, else it looses value. So if the company took additional 100 and did not / is not able to deploy in market, on 200 they still make 25 as profit, its bad. There are other reasons, i.e. to fight off hostile acquisition or dilute some of promoters shares etc. Thus the reasons for company to do a secondary PO are few and doing it often reduces the value for primary share holders as well as minority share holders.
