What Is a Stock?

A stock (also called an equity or a share) is a unit of ownership in a corporation. When you buy a stock, you become a partial owner — a shareholder — of that company.

As an owner you have:

• A claim on the company's assets and earnings proportional to your ownership stake
• The right to vote on major corporate decisions (common shareholders)
• The right to receive dividends when the company distributes profits

How Stock Prices Are Determined

Stock prices are set by supply and demand on an exchange (NYSE, NASDAQ, and others). At any moment, the price reflects the aggregate judgment of all buyers and sellers about what the company is worth today and in the future.

Prices move because:

• Earnings change — if a company earns more than expected, its stock typically rises
• Growth expectations shift — expectations about future revenue and profit drive valuations
• Market sentiment changes — fear and optimism cause prices to deviate from underlying value in the short term
• Interest rates change — rising rates reduce the present value of future earnings

Capital Appreciation and Dividends

Capital appreciation is the increase in share price over time. If you buy a stock at $40 and sell it at $70, you have earned $30 per share in capital appreciation.

Dividends are cash payments made by a company to its shareholders, typically quarterly. Not all companies pay dividends. Growth companies often reinvest profits rather than distributing them.

Together, capital appreciation and dividends constitute total return — the complete measure of what an investment earned.

Common vs. Preferred Stock

Common stock is the standard form of equity ownership. Common shareholders:

• Vote on major decisions (board elections, mergers)
• Receive dividends if declared (not guaranteed)
• Are paid last in a bankruptcy

• Receives a fixed dividend before common shareholders
• Does not typically carry voting rights
• Is paid before common shareholders in a bankruptcy

Risk, Return, and Time Horizon

Higher potential returns come with higher risk. Equity investments:

• Can lose value in the short term — sometimes significantly
• Have historically grown over long periods (10+ years)
• Experience temporary declines of 20–50% during recessions and bear markets

Understanding this relationship is what separates disciplined investors from reactive ones.

Application

Before proceeding to the next lesson, complete the following:

1. Look up the current stock price of one company whose products you use every day. Write down the price, the 52-week high and low, and whether the company pays a dividend.
2. Calculate what a $5,000 investment at an 8% annual return would be worth in 30 years using a compound interest calculator.
3. Write down your current emotional response to the idea of investing in individual stocks. Identify whether that emotion is based on knowledge or assumption.
