WHAT IS SHARE ?

In finance a share is a unit of account for various financial instruments including stocks, mutual funds, limited partnerships, and REIT's. In British English, the usage of the word share alone to refer solely to stocks is so common that it almost replaces the word stock itself.

In simple Words, a share or stock is a document issued by a company, which entitles its holder to be one of the owners of the company. A share is issued by a company or can be purchased from the stock market.

By owning a share you can earn a portion and selling shares you get capital gain. So, your return is the dividend plus the capital gain. However, you also run a risk of making a capital loss if you have sold the share at a price below your buying price.
