In financial markets, a share is a unit used as mutual funds, limited partnerships, and real estate investment trusts.Share capital refers to all of the shares of an enterprise. The owner of shares in the company is a shareholder (or stockholder) of the corporation. A share is an indivisible unit of capital, expressing the ownership relationship between the company and the shareholder. The denominated value of a share is its face value, and the total of the face value of issued shares represent the capital of a company, which may not reflect the market value of those shares.
The income received from the ownership of shares is a dividend. The process of purchasing and selling shares often involves going through a stockbroker as a middle man. There are different types of shares such as equity shares, preference shares, bonus shares, right shares, and employees stock option plan shares.
Shares are valued according to the various principles in different markets, but a basic premise is that a share is worth the price at which a transaction would be likely to occur were the shares to be sold. The liquidity of markets is a major consideration as to whether a share is able to be sold at any given time. An actual sale transaction of shares between buyer and seller is usually considered to provide the best prima facie market indicator as to the "true value" of shares at that particular time.
Tax treatment of dividends varies between tax jurisdictions. For instance, in India, dividends are tax free in the hands of the shareholder up to Rs 10 lakhs, but the company paying the dividend has to pay dividend distribution tax at 12.5%. There is also the concept of a deemed dividend, which is not tax free. Further, Indian tax laws include provisions to stop dividend stripping.
Historically, investors were given share certificates as evidence of their ownership of shares. In modern times, certificates are not always given and ownership may be recorded electronically by a system such as CREST or DTCC, a central securities depository.
