shares of a company can be bought through an IPO or through the share market.
Share market is a common place for buyers and sellers to meet .
Face value of the share is irrelevant . The current price of the share , Dividend issued is what is important .
The two main exchanges in India are NSE and BSE
Dividend is not a compulsion . The directors f the company must decide if they are able to give dividend to the share holders or they wish to reinvest the amount in operations .
The health of the financial market is determined by seeing the index . The two main indexes in Indian markets are Sensex and Nifty.
