What Are Stocks? A Beginner Guide

How stocks work

Companies can sell shares of stock to raise money and allow investors to participate in the company’s future growth. After a company’s shares trade on the stock market, investors can buy and sell those shares through a brokerage account.

The stock price changes because buyers and sellers constantly react to new information. Earnings, business growth, interest rates, competition, inflation, economic news and investor sentiment can all affect stock prices.

Simple example: buying one stock

Imagine a beginner buys one share of a company for $100. If the share price later rises to $120 and the investor sells, the investor may have a $20 gain before taxes and possible fees. If the price falls to $80 and the investor sells, the investor may have a $20 loss.

This simple example shows why beginners should understand both potential growth and potential loss before investing. A stock is not the same as a savings account. Its value can change every trading day.

Why do companies issue stock?

A company may issue stock to raise money for growth, expansion, research, hiring, debt repayment or other business needs. By selling shares, the company gives investors a chance to own part of the business.

In return, investors hope the company becomes more valuable over time. But there is no guarantee. A business can perform well, poorly or somewhere in between.

How investors can make money from stocks

There are two common ways investors may make money from stocks: price growth and dividends.

1. Stock price growth

If a stock becomes more valuable and you sell it for more than you paid, you may have a capital gain. In taxable accounts, capital gains may be taxable.

2. Dividends

Some companies pay dividends, which are payments to shareholders. Not all companies pay dividends, and dividends are not guaranteed. Dividends may also be taxable in a taxable account.

Why stock prices move

Stock prices move because investors constantly update what they think a company is worth. If investors become more optimistic, the price may rise. If investors become more worried, the price may fall.

Some common reasons stock prices move include company earnings, revenue growth, profit margins, new products, lawsuits, leadership changes, industry competition, interest rates, inflation, recessions and overall market fear or optimism.

Why individual stocks can be risky

Buying one stock means your result depends heavily on one company. If that company has bad earnings, loses customers, faces lawsuits, becomes less competitive or disappoints investors, the stock price can fall.

This is why many beginners learn about ETFs and index funds before buying individual stocks. A diversified fund can hold many companies instead of relying on only one business.

Stocks vs ETFs

A stock is ownership in one company. An ETF is usually a basket of investments that may hold many companies. For example, instead of buying one company, an investor may buy an ETF that tracks a broad market index.

This does not mean ETFs are risk-free. ETFs can also lose value. But they may reduce company-specific risk because the investment is spread across many holdings.

Stocks vs saving money

Saving money usually means keeping cash in a safer and more stable place, such as a bank account. Investing in stocks means accepting more risk in exchange for the possibility of long-term growth.

Money needed soon, such as rent, emergency expenses or short-term bills, usually should not be exposed to stock market risk. Many beginners first build emergency savings before investing.

What beginners should avoid

Beginners should be careful with social media stock tips, hot stock predictions, short-term trading, investing rent money, borrowing money to invest and putting all their savings into one company.

A better first step is to learn the basics, understand risk, build emergency savings and start with a simple long-term plan.

Practical beginner example

A beginner has $200 available after paying bills and building some emergency savings. They are interested in buying one popular stock because people online are talking about it.

Before buying, a more careful beginner might ask: Do I understand the company? Do I know how it makes money? Would I be comfortable if the price dropped? Is this only a small part of my overall plan? Do I understand that I may owe taxes if I sell for a profit?

This kind of thinking does not guarantee success, but it helps the beginner slow down and avoid making a decision only because of hype.
