Equity security definition

What is an Equity Security?

An equity security is a financial instrument that represents an ownership share in a corporation. The instrument also gives its holder the right to a proportion of the earnings of the issuing organization. The typical equity security is common stock, which also gives its owner the right to a share of the residual value of the issuing entity, in the event of a liquidation. A less-common equity security is preferred stock, which may also provide its owner with a periodic dividend, along with other rights that give it a priority interest over the holders of common stock.

Stock Options and Warrants

A variation on the equity security concept is the stock option and the warrant; both instruments give their holders the right, but not the obligation, to acquire shares in a corporation at a certain price, and over a predetermined period of time. These options and warrants have value, so - depending on the circumstances - it may be possible to trade them to a third party.

Advantages of Equity Securities

There are several advantages to owning equity securities, which include the following:

  • Ownership and voting rights. Buying equity securities gives you partial ownership of a company. Shareholders often have the right to vote on key decisions, such as electing board members or approving mergers, giving them influence over corporate governance. A sufficiently large amount of ownership of equity securities will give the owner voting control over a business.

  • Capital appreciation. Equity securities offer significant growth potential. If the company performs well, the value of its stock may increase, allowing investors to realize capital gains when selling shares at a higher price.

  • Dividend income. Many companies pay dividends to shareholders, providing a source of passive income. Dividends can be periodic (e.g., quarterly) and add to the overall return on investment.

  • Liquidity. Stocks of publicly traded companies are highly liquid. Investors can buy or sell equity securities quickly and easily through exchanges, often at low transaction costs.

  • Diversification. Investing in equities allows for portfolio diversification across industries, geographies, and market sectors. This helps manage risk and improves overall returns.

  • Inflation hedge. Historically, equities have outperformed other asset classes like bonds during inflationary periods because companies can adjust prices to offset inflation, preserving profitability and investor value.

  • Limited liability. Shareholders have limited liability, meaning their losses are capped at the amount they invested. They are not personally liable for the company's debts or obligations.

  • Potential for higher returns. Compared to fixed-income securities like bonds, equities tend to offer higher long-term returns due to the potential for business growth and market appreciation.

  • Participation in company success. As part owners, equity investors directly benefit from a company's financial success through share price appreciation and dividends, aligning their interests with the company's growth.

Restrictions on Equity Securities

Depending on the restrictions noted on the face or back of a stock certificate, it may be possible to sell shares to a third party. These restrictions are present when a business is privately held. Or, the restrictions are imposed during the first few months after an initial public offering, so that sales by insiders will not have a negative impact on share prices.

Who Can Issue Equity Securities?

Only corporations issue equity securities. They are not issued by non-profit entities, partnerships, or sole proprietorships. It is much easier for a large publicly-held corporation to issue equity securities, since they can readily sell the shares on a stock exchange.
