Stocks

What Is a Stock?

A stock, also known as equity, represents a fractional ownership stake in a company. Shareholders hold a claim to a share of the company’s assets and earnings based on how many shares they own—these ownership units are called shares.

Shares are traded mainly on public exchanges, though private transactions also happen. They form a core piece of many personal investment strategies and are overseen by regulators to help guard against fraud. Over the long run, stocks have historically outpaced many other types of investments, and most online brokerages make buying and selling them straightforward.

• Where Stocks Trade: Most stock trading happens on public exchanges, though private deals occur too, and stocks remain central to most investment strategies.
• Long-Term Performance: Historically, stocks have outperformed many other asset classes over the long term.

Understanding Stocks

Companies issue stock to fund their business operations. Buying stock makes you a shareholder — a partial owner of the company. Depending on the share class, shareholders may be entitled to a portion of the company’s profits and assets. Ownership is proportional: if a company has 1,000 shares outstanding and you hold 100, you effectively own 10 percent of its earnings and assets.

Shareholders don’t own the company directly; they own the stock it has issued. Corporations exist as separate legal entities, which lets them hold property, take on debt, pay taxes, and be party to legal matters. That means a corporation’s assets belong to the business itself, not to its shareholders — office furniture the company buys, for instance, belongs to the corporation, not to any individual investor.

This distinction matters because it legally separates a corporation’s assets from its shareholders’ personal property, limiting liability on both sides. If a company goes bankrupt, a court can order its assets sold, but shareholders’ personal belongings stay protected — their shares may lose most of their value, but they’re never forced to sell them. The reverse holds too: if a major shareholder goes bankrupt personally, their creditors can’t touch the corporation’s assets to cover the debt.
