Investing in America Explained for Immigrants: A Beginner’s Guide

A Topic Many Newcomers Never Hear About

When we come to the United States, conversations about money usually start with the basics: open a bank account, build credit, pay the bills, save what you can.

Those are important first steps. Investing is another topic that often does not come up, even though it can play a role in long-term goals such as retirement.

In the United States, many people can invest through accounts that let them buy small pieces of businesses or loans to companies and governments. Investing also involves risk, and you can lose money.

This guide explains what investing is, how the stock market works, why time matters, and what risks to understand before you begin. It is general education, not a recommendation to buy any investment.

What Is Investing?

Investing means using money to buy something, such as a share of a company or a bond, with the hope that it will grow in value or pay income over time.

Money in an insured savings account is protected up to legal limits and usually earns some interest. Investments are different. They are not covered by FDIC deposit insurance, even if you buy them through a bank, and their value can go up or down.

In exchange for that risk, investments such as stocks have the potential to grow more than a savings account over long periods. There is no guarantee. According to Investor.gov, past performance cannot predict how an investment will perform in the future.

What Is the Stock Market?

The stock market is often discussed but not always explained. Here are the basics.

What a stock is

When a company wants to raise money to grow — to hire employees, build facilities, develop new products — one way it can do this is by selling small pieces of ownership to the public. Each piece is called a share or a stock.

When you buy a share, you become a part-owner of that company. If the company becomes more valuable, the price of your share may rise. If the company shares its profits with owners, you receive a payment called a dividend. If the company performs poorly, the value of your share may fall. This is one of the risks of owning shares of individual companies.

What the stock market is

The stock market is the system through which shares are bought and sold. Shares of many companies trade on stock exchanges.

When you hear that “the market went up today,” it usually refers to a measure of many stock prices together, called an index. An index tracks the prices of a group of stocks.

Why does the market go up and down?

Stock prices change often. Company results, economic news, and many other events can affect them. Over a day or a week, prices can move a lot in either direction.

Prices can fall sharply, and it can take a long time for them to recover. They may not recover at all for a particular company. Past market performance does not guarantee future results.

Trying to predict the best time to buy and sell, called timing the market, is very difficult. Many long-term investors focus instead on how long they plan to stay invested, and on choosing investments that match that time frame and their tolerance for risk.

Compound Growth

Compound growth means that growth can build on earlier growth. If an investment earns a return and you leave that return invested, future returns are earned on the larger amount.

Hypothetical example (a steady made-up rate used only to show the math; real investments do not grow at a steady rate, and they can lose value):

Suppose you invest $5,000 and it grows 8 percent in the first year. You now have $5,400. If it grows 8 percent again the next year, the growth is calculated on $5,400, not $5,000. That is $432, bringing the total to $5,832.

If that same hypothetical 8 percent rate continued every year with no withdrawals and no costs:

  • After 10 years: about $10,795
  • After 20 years: about $23,305
  • After 30 years: about $50,313

This shows why time matters in compounding: the longer money stays invested, the more years growth has to build on itself. It is not a prediction. Actual results can be much higher or lower, and fees and taxes reduce returns.

The same idea applies to regular contributions. Someone who starts contributing earlier has more years for compounding to work than someone who starts later with the same monthly amount, all else being equal.

You can test your own hypothetical numbers with the compound interest calculator on Investor.gov.

How Investing Works in Practice

Brokerage accounts

Many people buy investments through a brokerage account at a brokerage firm. Some employers also offer retirement plans that include investment options.

Opening a brokerage account is similar to opening a bank account: you provide personal information, the firm verifies your identity, and you add money to the account. Requirements vary by firm.

Before opening an account or working with an investment professional, you can check whether they are registered using the free search tools on Investor.gov. Compare fees and account terms, because costs reduce your returns.

What you can buy

Common investments include:

Individual stocks. Ownership in a single company. The price can rise or fall a lot, and a single company can lose most or all of its value.

Bonds. A type of loan you make to a company or government, which generally pays interest. Bonds carry risks too, including the risk that the issuer cannot pay, and their value can go down.

Mutual funds. Funds that pool money from many investors to buy a mix of investments.

Exchange-traded funds (ETFs). Funds that also hold a mix of investments and trade on an exchange like stocks.

Index funds. Mutual funds or ETFs that try to track a market index. They are explained below.

What Index Funds Are

An index fund is a mutual fund or ETF that seeks to track the returns of a market index.

Diversification. Because an index fund holds many investments, a problem at one company affects only a small part of the fund. Spreading money across many investments is called diversification. According to Investor.gov, diversification can reduce risk, but it cannot guarantee that your investments won’t lose value if the market drops.

Costs. Index funds often have lower costs than actively managed funds, because they follow an index instead of paying managers to pick investments. Investor.gov notes that not all index funds have lower costs, so check a fund’s fees before investing.

Risks. An index fund carries the risks of the investments it holds. If the market or index falls, the fund falls too. A fund may also not track its index exactly, because of fees, expenses, and other factors.

Many beginners learn about index funds because they offer a simple way to diversify. Whether any investment is right for you depends on your goals, time frame, and tolerance for risk. Read a fund’s prospectus before you invest.

Risk and Time

All investing involves risk. The value of investments can go down as well as up, and you can lose money, including the amount you invested.

Time is an important part of thinking about risk.

Money you need soon. If you might need money in the next few years, a market drop could force you to sell at a loss. Many people keep short-term money, including emergency savings, in insured savings accounts rather than in investments whose value can fall.

Money for long-term goals. Money you do not expect to need for many years has more time to recover from drops. That is not a guarantee: markets can stay down for long periods, and some investments never recover.

A useful question to ask is: when might I need this money?

Before investing, consider the basics. Investor.gov says no investment strategy pays off as well as, or with less risk than, eliminating high-interest debt. Paying down high-interest debt, such as credit card balances, and building emergency savings are common steps to take before investing.

Watch for fraud. Be skeptical of anyone who promises guaranteed returns, high returns with little or no risk, or pressures you to act quickly.

Learning Before You Invest

Now you understand what investing is, how the stock market works, how compound growth depends on time, what index funds are, and why risk matters.

If you are unsure whether investing fits your situation, consider talking with a registered investment professional. You can check registration on Investor.gov.
