You cannot have a steady stream of income by investing in stocks unless you have a reliable strategy. You are also not limited to using a single strategy. You can combine the following strategies, modify them, or even come up with your own. The important thing is that you use a strategy to turn the odds in your favor.
Why do companies come to Share Market? 
A company enters the primary market to raise funds. It is in the primary market that a company gets registered to issue shares to the public and raise money. Companies generally get listed on the stock exchange through the primary market route. 
Initial Public Offering (IPO) is the process by which a private company can go public by sale of its stocks to general public. It could be a new, young company or an old company which decides to be listed on an exchange and hence goes public.
Companies can raise equity capital with the help of an IPO by issuing new shares to the public or the existing shareholders can sell their shares to the public without raising any fresh capital.
ASBA process facilitates retail individual investors bidding at a cut-off, with a single option, to apply through Self Certified Syndicate Banks (SCSBs), in which the investors have bank accounts. SCSBs are those banks which satisfy the conditions laid by SEBI. SCSBs would accept the applications, verify the application, block the fund to the extent of bid payment amount, upload the details in the web based bidding system of NSE, unblock once basis of allotment is finalized and transfer the amount for allotted shares to the issuer.
Applications Supported by Blocked Amount (ASBA) is a process developed by the India's Stock Market Regulator SEBI for applying to IPO. In ASBA, an IPO applicant's account doesn't get debited until shares are allotted to them.
ASBA allows the investors money to remain with the bank till the shares are allotted after the IPO. Only then does the money transfer out of the investors account to the company. This eliminates the need for refunds on shares not being allotted.
