Equity is unsecured and a high risk-return investment
When you invest your money in a debt investment such as a bank deposit, bonds, etc., you are promised a fixed amount of interest on your investment and return of capital. This isn't the case with an equity investment. By becoming an owner, you bear the risk of the company not being successful. However, the rewards for bearing this risk are high. You, as an equity shareholder, are entitled to a share in the profits of the company’s business as well as any appreciation in the perceived value of the shares.

The risks and rewards of investing in equity are clearly apparent from the Bombay Stock Exchange Sensitive Index (BSE Sensex), which is a popular stock market index. This index reflects the movement of the share prices on the stock markets. The Sensex rises and/or falls continuously during trading hours. Rises indicate gains and falls indicate losses. True equity money is unsecured and directly reflects the faith of the investor in the business, its management and the commitment of its principals to it.

Equity remains in perpetual existence
The perpetual existence of a company implies that the death, disability, retirement or termination of a shareholder, director or officer, will not affect the existence of the company. For an equity shareholder, this is convenient since he does not need to renew/renegotiate the terms of his investment (like in the case of a fixed tenure debt investment). He also has the option to sell his equity holding through the stock exchange if he no longer wants to remain invested in the company.

Limited liability
Another extremely important feature of equity is its limited liability, which means that, as a part-owner of the company, you are not personally liable if the company is not able to pay its debts. In case of other entities such as partnerships, if the partnership goes bankrupt, the partners are personally liable towards the creditors/lenders and they may have to sell off their personal assets like their house, car, furniture, etc., to make good the loss. In case of holding equity shares, the maximum value you can lose is the value of your investment. Even if a company of which you are a shareholder goes bankrupt, you can never lose your personal assets.
