Yes Now days all were just asking one question that what is all this shares and little of them were know that what are they,So i am giving you an overview that what is shares and what u can make out from the company shares.
As in India there are Basically two share markets Sensex And Nifty ( there are other but the main stock exchange of the India were this two) In sensex the shares of every company were added and on daily basis the price of per share were fix by the person that deals in that share.But first knowing that u should have the knowledge about the shares.
So shares are the business when you divide that business into small pieces and sell those pieces or that were said to be stocks,to the interested person who wanna get his share in the company. We can say Share(stock) as an ownership in a company(in that company whose stock or share u buy).
The money that raise from selling those shares by the business is be used to build new plants and facilities the pay down debt or to acquire any another company(it's according to the company plan they have with them).So when an buyer buys the share he/she get his share and becomes the shareholder of the company.By that the buyer can get dividend on the share according to the profit earn by the company or he can simply buy that share when the prices move upward.
So basically shares are to be an income source that help both company and share holder in their way.Company gets money to fulfill his projects which he wanna do and the buyer gets the shares of the company and later he can sell them on higher rate.
