To learn more about how you can earn on the stock market, one has to understand how it works. A person desirous of buying/selling shares in the market has to first place his order with a broker. When the buy order of the shares is communicated to the broker he routes the order through his system to the exchange. The order stays in the queue exchange's systems and gets executed when the order logs on to the system within buy limit that has been specified. The shares purchased will be sent to the purchaser by the broker either in physical or demat format.
The Bombay Stock Exchange (BSE) and the National Stock Exchange of India Ltd (NSE) are the two primary exchanges in India. In addition, there are 22 Regional Stock Exchanges. However, the BSE and NSE have established themselves as the two leading exchanges and account for about 80 per cent of the equity volume traded in India. The average daily turnover at the exchanges has increased from Rs 851cr in 1997-98 to Rs 1,284cr in 1998-99 and further to Rs 2,273cr in 1999-2000 & to Rs 14000cr in 2009-2010 & 29410cr in 2017-2018. NSE has around 1900 shares listed with a total market capitalization of around Rs 14044152 crore (Rs 14044-bln) in 2017-2018.The BSE has over 6000 stocks listed and has a market capitalization of around Rs 10, 82,968 crore (Rs 10829-bln) in 2017-2018 Most key stocks are traded on both the exchanges and hence the investor can buy them on either exchange. Both exchanges have a different settlement cycle, which allows investors to shift their positions on the bourses. The primary index of BSE is BSE Sensex comprising 30 stocks. NSE has the S&P NSE 50 Index (Nifty) which consists of fifty stocks. The BSE Sensex is the older and more widely followed index. Both these indices are calculated on the basis of market capitalization and contain the heavily traded shares from key sectors. The markets are closed on Saturdays and Sundays. Both the exchanges have switched over from the open outcry trading system to a fully automated computerized mode of trading known as BOLT (BSE On Line Trading) and NEAT (National Exchange Automated Trading) System. It facilitates more efficient processing, automatic order matching, faster execution of trades and transparency. The scrip’s traded on the BSE have been classified into 'A', 'B1', 'B2', 'C', 'F' and 'Z' groups. The 'A' group shares represent those, which are in the carry forward system (Badla). The 'F' group represents the debt market (fixed income securities) segment. The 'Z' group scrip’s are the blacklisted companies. The 'C' group covers the odd lot securities in 'A', 'B1' & 'B2' groups and Rights renunciations. The key regulator governing Stock Exchanges, Brokers, Depositories, Depository participants, Mutual Funds, FIIs and other participants in Indian secondary and primary market is the Securities and Exchange Board of India (SEBI) Ltd.
In a rolling settlement, each trading day is considered as a trading period and trades executed during the day are settled based on the net obligations for the day. At NSE and BSE, trades in rolling settlement are settled on a T+2 basis i.e. on the 2nd working day. For arriving at the settlement day all intervening holidays, which include bank holidays, NSE/BSE holidays, Saturdays and Sundays are excluded. Typically trades taking place on Monday are settled on Wednesday, Tuesday's trades settled on Thursday and so on.
Dematerialization in short called as 'demat is the process by which an investor can get physical certificates converted into electronic form maintained in an account with the Depository Participant. The investors can dematerialize only those share certificates that are already registered in their name and belong to the list of securities admitted for dematerialization at the depositories.
Depository: The organization responsible to maintain investor's securities in the electronic form is called the depository. In other words, a depository can therefore be conceived of as a "Bank" for securities. In India there are two such organizations viz. NSDL and CDSL. The depository concept is similar to the Banking system with the exception that banks handle funds whereas a depository handles securities of the investors. An investor wishing to utilize the services offered by a depository has to open an account with the depository through a Depository Participant.
Depository Participant: The market intermediary through whom the depository services can be availed by the investors is called a Depository Participant (DP). As per SEBI regulations, DP could be organizations involved in the business of providing financial services like banks, brokers, custodians and financial institutions. This system of using the existing distribution channel (mainly constituting DPs) helps the depository to reach a wide cross section of investors spread across a large geographical area at a minimum cost. The admission of the DPs involves a detailed evaluation by the depository of their capability to meet with the strict service standards and a further evaluation and approval from SEBI. Realizing the potential, all the custodians in India and a number of banks, financial institutions and major brokers have already joined as DPs to provide services in a number of cities.
Normally to buy and sell shares, you need to have the money to pay for your purchase and shares in your demat account to deliver for your sale. However as you do not have the full amount to make good for your purchases or shares to deliver for your sale you have to cover (square) your purchase/sale transaction by a sale/purchase transaction before the close of the settlement cycle. In case the price during the course of the settlement cycle moves in your favor (risen in case of purchase done earlier and fallen in case of a sale done earlier) you will make a profit and you receive the payment from the exchange. In case the price movement is adverse, you will make a loss and you will have to make the payment to the exchange. Margins are thus collected to safeguard against any adverse price movement. Margins are quoted as a percentage of the value of the transaction.
