As per Securities Contract Act, 1956 a stock exchange is an “association, organisation or body of individuals whether incorporated or not, established for the purpose of assisting, regulating and controlling the business in buying, selling and dealing in securities. Therefore stock exchange is a place where securities issued by companies are listed and traded.

The leading stock exchanges in the world are:-

How the value of an index is determined?

Market capitalization (market cap) is the total market value of the shares outstanding of a publicly traded company; in other words,

Market cap = Number of shares outstanding * Market Value of a share

 

Index Value   = Index value of previous day * Market capitalisation of current day/Market                                                                                                                                                                                                              of next day                                                                                       capitalisation of previous day

 

So the total value of market capitalisation is computed by adding up the total value market cap of the traded shares in the particular index.

Index value can be computed based on price weighted method also instead of market cap weigh method. However, most indexes use the market capitalisation method for computation of index value.

 

In order to understand the working of stock exchanges we need to understand various participants in the capital markets

  • Investor: – For any capital market to be successful it should be able to attract the funds from investors. They are the lifeline of any capital markets. A market is termed as bullish when the investor sentiments are positive i.e, when there is sufficient fund inflow into the market.
  • Stock Exchange: – Stock Exchange is the place where buying and selling of securities happens. It helps in raising funds for the businesses and maximising shareholders wealth. The performance of stock exchange reflects the state of a country’s economy.
  • Clearing House: – Clearing house is an exchange associated body which provide various services such as clearance and settlement of trades, guarantee of contracts, and management of the risk of its members.
  • Depositories: – Depositories are organisations which hold securities of an investor in electronic form. In India, normally the T+ 2 day is the settlement date i.e. 2 days from the transaction or purchase date. So after 2 days from the purchase date the securities will be held with the depository which charges a minimal fee for its services.

 

How does a stock exchange function (a step by step analysis)?

  • Client has to open an account with a member of a stock exchange. They charge brokerage for their services.
  • Client needs to infuse funds into the demat linked account to invest or trade in securities.
  • Once the fund is added, the client can start buying and selling in securities.

A clearing house acts a medium of transaction between a buyer and a seller. The clearing house becomes the buyer for all the sellers and seller for all the buyers. So a share can be bought and sold at any point of time. So margins are levied for all transactions depending upon the type of instrument in order to reduce the risk of the clearing house.

  • The value of a share fluctuates depends upon its demand on a particular day in the market. Investors tend to invest in a share depending on its growth prospects and dividend policy.
  • The client can deal in securities on intraday basis (buying and selling in the same day) or can be held on short term or long term basis.

  1. In the beginning, I participated in some Investment Programs but without earning anything from it. I decided then to invest directly via Brokers. I noticed that it would be more simple to use a Perfect Trading Robot. I tried to look for a good System. Unfortunately, no Robot convinced me! While continuing my searches I found on the Net an advice: if you want a good Robot, you have to conceive it and develop it yourself! As being a Developer IT specialist, I decided to produce my own EA.
