What You Can Invest In

Step 5 — Learn What You Can Actually Invest In

Now you know where your investments can live.

The next question is:

What actually goes inside the account?

This is where investing can start to feel overwhelming. You open a brokerage platform and suddenly see hundreds or thousands of stocks, ETFs, mutual funds, and other investments.

You don’t need to understand all of them.

As a beginner, start by understanding a few of the most common investment types:

• Stocks
• ETFs
• Index funds
• Mutual funds
• Bonds

Once you understand what these are and how they differ, the investing world becomes much easier to navigate.

Stocks

A stock represents ownership in a company.

When you buy a share of a company’s stock, you’re buying a small ownership interest in that business.

If the stock price increases, your investment can increase in value.
If the stock price falls, your investment can lose value.

That’s the basic idea.

The challenge is that an individual company’s future is difficult to predict. A business can perform poorly, face unexpected problems, lose customers, or experience other events that cause its stock price to fall.

That’s one reason owning a single company’s stock can expose you to concentration risk. If that one company struggles, your investment can be affected significantly.

For beginners, it’s important to understand that buying stocks is not the same thing as owning a diversified portfolio.

ETFs

An ETF (exchange-traded fund) is a type of investment fund that can hold a collection of investments.

Instead of buying shares of dozens or hundreds of companies individually, you may be able to buy shares of an ETF that already holds many investments.

Think of it like a basket.

Instead of buying:

Company A + Company B + Company C + Company D + …

you could potentially buy one fund that holds many of them.

The exact investments inside an ETF depend on the particular fund.

Some ETFs track broad market indexes. Others focus on specific industries, countries, company sizes, investment strategies, or other categories.

That’s why simply buying an ETF does not automatically mean you’re diversified. You need to understand what the ETF actually owns.

Index Funds

An index is a group of investments designed to represent a particular part of the market.

An index fund is a fund designed to track the performance of an index.

For example, an index might track a broad group of large publicly traded U.S. companies. An index fund designed to track that index would seek to follow its performance rather than trying to pick individual companies that a manager believes will outperform.

Index funds can come in different forms, including ETFs and mutual funds.

This is an important distinction:

• “Index fund” describes how a fund is managed or what it seeks to track
• “ETF” describes a type of fund structure that trades on an exchange

An ETF can be an index fund, but not every ETF is an index fund.

Mutual Funds

A mutual fund is another type of investment fund.

Like an ETF, a mutual fund can hold many different investments inside one fund.

Mutual funds can follow an index or use an active strategy where a fund manager makes investment decisions.

One major difference is how they’re bought and sold.

ETFs trade throughout the trading day on an exchange, similar to stocks. Mutual funds are generally bought or sold at a price calculated at the end of the trading day.

There are other differences involving fees, taxes, minimum investments, and how transactions work, depending on the specific fund and account.

For now, the important takeaway is simple:

Both ETFs and mutual funds can give you exposure to many investments through a single fund.

Bonds

You may also encounter bonds when learning about investing.

A bond is essentially a loan made by an investor to a borrower, such as a company or government.

In return, the borrower generally agrees to pay interest and return the principal according to the terms of the bond.

Bonds have different risks from stocks. Their prices can still fluctuate, and bonds are not automatically “safe.” Factors such as interest rates, credit risk, and the financial condition of the borrower can affect their value.

For a complete beginner, you don’t need to master the bond market before moving forward. Just understand that stocks and bonds are different types of investments with different characteristics and risks.

What Does Diversification Mean?

You’ve probably heard the word diversification before.

It simply means spreading your money across different investments rather than relying heavily on one.

Think about it like carrying groceries.

If you carry everything in one bag and that bag breaks, you have a problem.
If you split the groceries between several bags, one broken bag doesn’t necessarily ruin everything.

Investing works differently, but the basic idea is similar.

A diversified fund may hold many companies, which means the performance of your investment isn’t dependent on just one company.

However, diversification has limits.

A fund can hold hundreds or thousands of investments and still fall in value when the broader market declines.

Diversification can reduce concentration risk, but it does not guarantee profits or prevent losses.

One investment can also fit into more than one category. For example, an ETF can also be an index fund.

That’s why it’s better to understand what an investment owns and how it works rather than relying only on the label.
