Q.What is a Stock Exchange?

A stock exchange is simply the organised market where shares and other securities are traded under fixed rules, so a short answer should give the meaning and name a real example.

A stock exchange is an organised and legally recognised market where securities such as equity shares, debentures, bonds and government securities are bought and sold under a well-defined set of trading rules. The Securities Contracts (Regulation) Act, 1956 defines it as a body corporate or association of persons formed to assist, regulate and control the business of dealing in securities.

Its key features are: (i) it is an organised market functioning under fixed rules and timings; (ii) only listed securities can be traded on it; (iii) only its registered members can transact business, and the investing public deals through them; (iv) it functions under the regulatory supervision of SEBI; and (v) it provides liquidity, since securities can be converted into cash and back with reasonable speed. In India, the BSE and the NSE are the two principal stock exchanges.

Students often define a stock exchange as merely 'a place to buy and sell shares' without mentioning that it is organised, rule-bound and regulated by SEBI — all three qualifiers are needed for full marks.
