Common Stock

What Is Common Stock?

Common stock is a unit of ownership in a corporation. When you buy common shares, you become a part-owner of the company, with a claim on its future profits and a say in certain major decisions. It is the standard form of equity that most public companies issue, and it is the type of stock most people mean when they talk about owning shares.

How Common Stock Works

Common shareholders typically have the right to vote on matters such as electing the board of directors and approving major corporate actions, usually on a one-share, one-vote basis. Their returns come from two main sources: dividends, which are paid at the discretion of the board, and capital gains, which arise when the share price rises above the purchase price.

Common stock sits at the bottom of a company's capital structure. If the company is liquidated, creditors and preferred stock holders are paid first, and common shareholders receive whatever remains. This lower priority is the main reason common stock is considered riskier than debt, but it also gives shareholders unlimited upside if the business grows.

Advantages and Disadvantages

For individual investors, common stock offers liquidity on public exchanges, the potential for long-term price appreciation, and a voice in corporate governance. The drawbacks include no guaranteed income, the possibility of losing the entire investment if a company fails, and price volatility that can be significant over short periods.

Common stock prices are influenced by company performance, industry trends, interest rates, and broader market sentiment. Investors often evaluate a company using measures such as the price-to-earnings ratio before deciding whether a share price reflects its underlying value.
