How to Invest in Shares in the USA (2025): A Complete Beginner’s Guide

Investing in stocks or shares, as it is known in the United States, is one of the most effective ways to build wealth over the long term. You can only earn so much interest in a savings account, but shares allow you to own your piece of a company and share in its growth. For many Americans, it is not just about earning a profit from a stock; it is about financial freedom, retirement, and generational wealth.

This comprehensive guide will take you through the steps of investing in shares in the USA in 2025, including understanding risk vs reward, the process of investing, and even a few tips to get you started building your portfolio today.

What Does It Mean to Invest in Shares?

Shares investing refers to owning a portion of a business. If a business grows and makes a profit, the value of the share increases.

You can make money from shares in two main ways:

Capital gains – When you sell your shares for more than you paid for them.
Dividends – Some businesses pay dividends to their shareholders with some of the profits.

Example: If you bought 10 shares of Microsoft at $300, equal to $3,000, then if the price of the shares went up to $350, you would have a gain of $500. If Microsoft pays dividends, you also participate in some of the profits without selling the shares.

Why Invest in Shares in the USA?

The U.S. stock market is the most significant and liquid in the world. Here are some of the primary reasons why Americans (and most investors around the world) invest in U.S. stocks:

Strong Historical Returns – Over the last one hundred years, U.S. stocks have historically returned approximately seven to ten percent per year after inflation.
Diverse Options – There is an incredibly diverse amount of alternatives available, such as technology companies like Apple and Google, to startups.
Easy Access – With online brokerages, investing has become easy, and there are often no commissions.

Wealth-Building – Shares have proven to be one of the most effective long-term wealth-building vehicles.
Beating Inflation – Stocks typically grow faster than inflation, which helps preserve your purchasing power over time.

Steps to Start Investing in Shares in the USA

Let’s break down how to get started step by step for a first-time investor.

1. Learn the Basics of Stock Market Investing

Do a bit of research on common terminology and concepts before investing your money:

Stock Exchange – The place where shares trade (the NYSE and NASDAQ are the two largest exchanges in the U.S.).
Ticker Symbol – A short version of the company’s name that generally consists of letters (e.g., AAPL for Apple, TSLA for Tesla).
ETF (Exchange-Traded Funds) – A combination of stocks you can invest in, and it is a great way to gain instant diversification.
Index Fund – An investment that allows you to track an index such as the S&P 500 (while investing in all the stocks that make it up).

2. Choose the Right Brokerage Account

You will need a brokerage account to purchase shares. Today, nearly all brokers offer commission-free trading, making it more affordable and accessible to all types of investors. Some popular options include:

Fidelity – Offers some of the best customer service and retirement tools.
Charles Schwab – Great for beginners, offering fractional shares.
TD Ameritrade – Has plenty of research tools and is great for active traders.
Robinhood – Easy-to-use mobile app, best for beginning investors.
E*TRADE – Good for lots of different investments.
Vanguard – Great option for long-term investors and known for low-cost index funds.

Tip: If you are investing with an eye toward retirement, consider using an IRA or 401(k) as a potential tax advantage that is sometimes not available in a brokerage account.

3. Set Your Budget and Goals

Next, you’ll want to figure out how much you want to invest and why. I suggest you ask yourself the following questions:

Are you investing for retirement?
Are you trying to earn dividend income?
Are you investing for short-term gains or long-term growth?

You don’t need to have thousands to invest. Thanks to fractional shares, you can invest in companies like Amazon or Google with as little as $5.

4. Research and Select Shares

It’s essential first to do rigorous research on a company before buying from it:

Financials – Earnings, revenue growth, and debt are good starting points.
Industry Trends – Is the company in a growing industry? (AI, renewable energy, healthcare?)
Valuation – Is the stock overpriced compared to its earnings?
Past Performance – Past performance does not guarantee future performance, but good companies will typically show stability.

Beginners should consider starting with ETFs or index funds (like the S&P 500) that allow you to invest in many companies, versus trying to pick individual stocks right away.

5. Diversify Your Portfolio

Never put all your money into one stock. Always try to spread your investments across different industries and sectors. A well-diversified portfolio will limit the risk and create balance in returns.

For example, instead of just buying Tesla shares, add in some healthcare stocks, some financial stocks, and maybe even some small ETFs.

6. Choose Your Investment Strategy

There are two investing strategies in the stock market:

Active Investing: Picking your individual stocks based on market trends, stock performance, or trading frequently.
Passive Investing: Buying ETFs or index funds and then holding for the long term.

Most beginners will be better served by passive investing because it requires less time, has lower costs, and typically returns more than active traders.

7. Invest Regularly (Dollar-Cost Averaging)

Instead of investing a lump sum, make a fixed monthly or weekly amount. This is called maximized dollar-cost averaging and will reduce the impact of the market’s ups and downs.

Risks of Investing in Shares

Putting money into stock investing is risky. Here are some things to look out for:

Market Risk – Prices can increase or decrease on a given day.
Company Specific Risk – A company can go bankrupt, causing the stock price to decline.
Emotionally Driven Trading – When the market is down, investors can incur a loss through emotional trading.
Over Trading – Investors can overtrade or become too focused on “hot stocks.”

Rule of thumb: only invest money you do not need to touch for 5 years.

Taxes on Shares in the USA

The IRS will tax your profits from stock market investments like this:

1. Capital Gains Tax

Short-term (less than 1 year) – Taxed at your regular income tax rate.
Long-term (1 year or more) – Taxed at lower rates (0%, 15% or 20%).

2. Dividend Tax:

Qualified dividends – taxed at lower rates.
Ordinary dividends – taxed at your regular income.

You should consider investing in Roth IRAs or in 401(k) accounts to mitigate your tax liabilities for longer-term stock investments, especially investing in stocks that pay dividends. Growth in these accounts is either tax-free or tax-deferred.
