What is Share Market?

Share Market is a public exchange where buy and sell shares of companies and works on the priciples of demand and supply of shares.  People are willing to pay a certain amount for an asset (stock, in this case) and they are willing to sell off something they have to a certain price.

How Does the Stock Market Work?

To understand how the stock market works, let us first dwell somewhat into the economics of supply and demand. After all, the stock market is a demand-supply matcher, and without proper demand and supply, there is no stock market.

Demand and Supply Curve:

Example of Stock Market - Demand & Supply Curve

The line ‘D’ is the demand, and ‘S’ is supply with a horizontal axis being the quantity (q) and the vertical axis (p) being the price. We can see that, as price increases, supply increases, and demand decreases. The point of the stock market is to find a midpoint and proceed with the transaction.

Market Price:

The current price of the stock;


The stock market works like an anonymous auctioning machine – one-person auctions his assets and waits for other people to bid the right amount. When the selling price matches the buying price, the transaction happens, and the stock market gets a cut.

Bid Price:

When multiple buyers want to buy a stock, they bid for the stock, and the highest price is called as the bid price.

Ask Price:

When multiple sellers start selling the stock, they ask for a certain price. The lowest of such price is called an ask priceAsk PriceThe ask price is the lowest price of the stock at which the prospective seller of the stock is willing to sell the security he holds. In most of the exchanges, the lowest selling prices are quoted for the purpose of the trading. Along with the price, ask quote might stipulate the amount of security which is available for selling at the given stated price.read more.

Example of Stock Market and Their Sizes

We can find the entire list of the stock market and their respective sizes over here. Us has the world’s two largest stock exchanges – The New York Stock Exchange, which holds companies of about 30 trillion market cap in total, and NASDAQ, which is one third the size of NYSE. Japan comes after NYSE and NASDAQ with about 6.5 trillion USD in total capitalization of stocks, and Shanghai and Hong Kong come later with 4 and 3 trillion each. Just by looking at the size of their stock markets, we can assume and make a decision on how big the companies are going to be. It gives us a general idea about what the size of the economy might be.

India has two stock markets – National Stock Exchange and the Bombay Stock Exchange, which each has 2 trillion USD in capitalized stocks. Remember that just because there are 2 exchanges doesn’t mean we can add them to get the total number of companies that have IPO’ed.

Also, event shares that are being traded privately are a part of the share market, and once the market opens, the price reflects the non-OTC (Over The CounterOver The CounterOver the counter (OTC) is the process of stock trading for the companies that don't hold a place on formal exchange listings.
