I want to know the details about the stock market.
Stock market is a 'market' or place where the stocks or company shares are traded. To conduct the trade in a smooth and orderly way, to protect the interest of the investors, agents or brokers, and the companies there are various rules and regulations by the Stock Exchanges. Early the trading was done by exchanging the stocks physically between the buyer and seller using the services of stock brokers. But now all these are done electronically. The main agents inside the stock exchanges pave way for the price quotes as per the need and request of retail brokers/investors and bulk investors. The price gets quoted on basis of demand and supply situation.
Can you tell about the process of how to buy stock from BSA and NSA?
I take that you are asking about NSE and BSE -National Stock Exchange and Bombay Stock Exchange respectively.
BSE was one of earliest stock exchange in the country and NSE is of a few years old.
In comparison NSE is a broader one than BSE. New companies get enlisted in both or NSE mainly.
The buying and selling of stocks takes place through licenced stock brokers having membership in the stock exchanges. There may be sub-brokers under direct stock brokers. As all stocks are now traded in non-physical or Demat form, we should also utilise the services of a Depository participant.
So today if one wants to transact in stocks, he should open a DEMAT account with a depository participant, then take the services of a stock broker to buy or sell stocks through a trading account, and have a own bank account to make or receive payments from stock transactions .
Some big firms do DP and brokers business as they have licences for both. Some banks also are DP and help in online trading by opening trading accounts also.
