Stock

Stock (also known as share, equity, or capital stock) is a financial security that represents partial ownership in a corporation. A stockholder, also known as a shareholder, possesses an ownership interest in the issuing company and may be entitled to voting rights, dividend payments, and a proportionate share of the company's residual assets after all debts and obligations have been satisfied in the event of liquidation. Companies issue stocks to raise capital for business operations, expansion, acquisitions, research and development, and other corporate purposes. Stocks are traded primarily on stock exchanges and constitute one of the principal asset classes in global capital markets.

History

The origins of publicly traded stock can be traced to the development of joint-stock companies during the sixteenth and seventeenth centuries. Early examples include the Dutch East India Company, founded in 1602, which is widely regarded as the first company to issue publicly tradable shares on a formal securities exchange. Similar corporate structures later emerged throughout Europe, facilitating the financing of long-distance trade and commercial enterprises.

During the nineteenth century, industrialization led to rapid growth in corporate financing through equity markets. The establishment of organized stock exchanges, including the New York Stock Exchange, the London Stock Exchange, and later numerous exchanges worldwide, expanded opportunities for companies to raise capital and for investors to participate in corporate ownership.

Today, stocks are traded globally through regulated securities exchanges and electronic trading platforms.

Characteristics

A stock generally possesses several key characteristics.

Shareholder	Person or entity owning shares
Voting rights	May permit participation in corporate governance

Stocks are commonly classified according to the rights attached to the shares.

Common stock

Common stock represents the standard form of corporate ownership.

Holders of common stock generally possess:

voting rights at shareholder meetings;
eligibility to receive dividends when declared;

Common shareholders typically bear greater investment risk but also participate more directly in corporate growth.

Preferred stock

Preferred stock generally provides shareholders with priority over common shareholders regarding dividend payments and claims on assets during liquidation.

Preferred stock often possesses characteristics of both equity and debt securities and may or may not carry voting rights.

Issuance

Companies issue stocks through various methods of equity financing.

These include:

initial public offering (IPO);
follow-on offering;
rights issue;
private placement;
employee stock ownership plans;
