Investments and shares

Q: Is stock business halaal? If I avoid items like bank, insurance, financial institution and so on? Again, When a new stock item comes into market it offers many people to apply for that and among them some people are allotted with that item primarily. It is done by a random selection. After that they return the money of others. After a limited time this primary stock comes into the regular stock market. Is this halaal or haraam in Islam? Can I apply for that primary stock item?
