Stock

Stock is  issue security fixing the rights of its owner (shareholder) on reception of a part of profit of joint-stock company in the form of dividends, on participation in management of joint-stock company and on a part of the property remaining after its liquidation.
A shareholder (or stockholder) is an individual or company (including a corporation) that legally owns one or more shares of stock in a joint stock company. Companies listed at the stock market are expected to strive to enhance shareholder value.
Shareholders are granted special privileges depending on the class of stock, including the right to vote (usually one vote per share owned) on matters such as elections to the board of directors, the right to share in distributions of the company’s income, the right to purchase new shares issued by the company, and the right to a company’s assets during a liquidation of the company. However, shareholder’s rights to a company’s assets are subordinate to the rights of the company’s creditors.
Shareholders are considered by some to be a partial subset of stakeholders, which may include anyone who has a direct or indirect equity interest in the business entity or someone with even a non-pecuniary interest in a non-profit organization. Thus it might be common to call volunteer contributors to an association stakeholders, even though they are not shareholders.
