What is a Stock?

Navigating the financial world can sometimes feel like a maze. However, understanding the basics of financial assets, such as stocks, can greatly simplify the journey. This article will unpack what a stock is, how it operates, and its importance in the financial ecosystem.

The Definition of a Stock

At its core, buying a stock means acquiring a fraction of ownership in a publicly traded company. When you purchase a stock, you officially become a shareholder. In essence, stocks, also referred to as equities, are securities signifying proportional ownership in an issuing corporation. This ownership gives you a claim to the company's assets and profits, relative to the amount of stock you own.

Why Companies Issue Stocks

Companies have two primary methods to amass capital necessary for expansion: borrowing funds (commonly via issuing bonds) or selling shares of their company's equity, also known as stocks. This process of issuing stocks is a key mechanism for companies to raise funds to operate their businesses or initiate new projects. Companies venture into the public market with Initial Public Offerings (IPOs), and the price of these shares is the sole capital the company raises from them.

Common vs. Preferred Stock

There are two main types of stock: common and preferred. The most common form, appropriately named Common Stock, grants shareholders voting rights in electing the company’s board members. If you own 1% of a company's common stock, you're entitled to 1% of the company's earnings, and you hold one vote out of 100 to elect board members. Preferred Stock, on the other hand, usually doesn't come with voting rights, but it provides a higher claim on earnings and assets.

Trading Stocks: Primary and Secondary Market

Once a company's stocks are available through an IPO, they are subsequently traded on exchanges in the Secondary Market. The profits and losses from these transactions impact only the buyers and sellers of the shares on the open market.

Stocks are predominantly bought and sold on stock exchanges, and these transactions must adhere to government regulations intended to shield investors from fraudulent practices. These exchanges include globally recognized platforms like the New York Stock Exchange (NYSE), Tokyo Stock Exchange (TSE), London Stock Exchange (LSE), and the NASDAQ.

Stocks and Bonds: A Comparative Analysis

It's important to distinguish between stocks and bonds. While stocks represent ownership, bonds represent a debt. Bondholders are creditors to the corporation and are entitled to interest and the repayment of the principal invested. In the event of a bankruptcy, creditors have legal precedence over other stakeholders and will be reimbursed first if a company has to liquidate assets.

The Significance of Stocks in Investment Portfolios

Stocks form the bedrock of many individual investors' portfolios. Historically, they have outperformed most other investments over the long run. Their potential for high returns, coupled with the opportunity to have a personal stake in a corporation, make them an attractive option for many investors.

Understanding stocks is fundamental to navigating the world of finance. As an investor, purchasing stocks gives you a share in a company's success (or failure). It's a mechanism that provides capital to businesses for growth and gives individuals the chance to invest in these businesses. Thus, the concept of a stock is a pivotal component of the modern economic structure.


Buying a stock means taking an ownership position in a publicly traded company. Once you purchase a stock, you become a shareholder.

A company has two ways of acquiring capital needed for growth: borrowing it (often in the form of issuing bonds), or selling shares of their company's equity, which is known as stock.

In other words, when you buy shares of a company’s stock, you are buying a claim to the company's profit margin, because you are technically a part-owner in the company. Those who hold shares of Common Stock, the most typical form of stock, have voting rights in the election of the company’s board members.

For example, if company ABC issues 100 shares, and you buy 1 share (so-called common stock), you will be entitled to 1/100, or 1% of ABC's earnings, and one vote out of 100 to elect members to the board of directors. If the company pays out dividends, you are entitled to 1% of these dividends.

If the company dissolves or is bought by another company, you will get 1% of the proceeds, assuming the company debts have been taken care of (including bond obligations. Shares of stocks of publicly-traded companies are traded on stock exchanges.

The biggest stock exchange in the world is the New York Stock Exchange (NYSE), but there are many others such as the Tokyo Stock Exchange (TSE), London Stock Exchange (LSE), and the Bombay Stock Exchange (BSE). There are even other exchanges within the U.S., such as NASDAQ.

Stocks enter the market with Initial Public Offerings (IPOs), and the price of those shares is the only capital that the issuing company will raise with them. After that, the stocks are traded on the exchanges in what’s referred to as the Secondary Market, and the profits and losses are attributable only to the buyers and sellers of the shares on the open market.
