What’s a stock?

A stock represents partial ownership in the assets and earnings of a company. The company sells stock to investors as a way raise cash to expand its business. Stocks may also be called equities.

Stocks are broken down into shares. For example, if you purchase AT&T stock, you now own shares of the stock. You are a shareholder.

Each share of stock has a value that changes every day. For example, if hypothetically you were to purchase 10 shares of AT&T at $35 a share, you’d pay $350 for those shares.1


In order to buy stock in a company, that company needs to be publically traded on an exchange, such as the New York Stock Exchange or Nasdaq. There are exchanges all over the world, including Europe’s Euronext and China’s Shanghai Stock Exchange.

When you read the news that a company announced its IPO, it’s announcing its initial public offering. An IPO is the first time the stock of a private company is offered for sale to the public.

Shareholders have power. Even if you only hold a single share, as a shareholder, you own a portion of that company. That’s a pretty cool thing.

Why do stocks go up and down? We’ll talk about this in our next guide Expand Your Horizons: Basic Investing Concepts.

What’s a bond?

A company, government, or municipality can raise money by issuing bonds.

A bond is what’s called a “debt instrument.” When you purchase a bond, you’re essentially lending money to whoever is issuing that debt.

Bond issuers borrow funds for a defined period of time, at a fixed interest rate. When you purchase a bond, you will receive interest at regular intervals, plus the initial amount you loaned.

This is why bonds that are considered ‘investment grade’ are considered particularly low risk. You know how much you will get, and when.

What’s a fractional share?

Hot tip: Fractional shares are a great way to start building a portfolio starting with the money you have.

They’re just what they sound like — fractions, or pieces of a whole share of stock, bond, or fund. You’re still investing in the company, but you don’t need to wait until you’ve got enough money to purchase an entire share.

For example, instead of having to find $171 to buy a full share of Apple, you can buy a small fraction of that, a fractional share.2

How do fractional shares add up to anything? Little amounts can earn interest, and that interest can compound over time.

You can purchase fractional shares of funds and selected single stocks on Stash.

It’s true: You can invest companies that excite you or sectors (technology, healthcare, aerospace and defense) that you think will pave the way toward a better future.

And you can start with just $5.

Chapter 2

What are funds?

  • Funds bundle together a variety of stocks, bonds, cash, or a combination.
  • Examples of funds include index funds, mutual funds, and exchange-traded funds (ETFs)
  • Funds can provide diversification
1 min read

You’re probably more familiar with funds than you think. A fund is simply a pool of money that will be used for a particular purpose. A college fund is a great example.

When talking about investing, more common types of funds are mutual funds, index funds, or exchange-traded funds.

Funds bundle together a variety of stocks, bonds, cash, or a combination of all three. This is part of what can make funds so great for beginner investors. This is particularly true of exchange-traded funds.

Because funds bundle together different investments, whether this is all equity (stocks) of technology companies, or bonds from major municipalities in the United States, a fund that bundles together multiple investments is more diversified than buying a single stock or a bond.

And as we discussed in Introduction to Investing, diversification is one of the most important aspects of solid investing strategy.

Chapter 3

How do you create a portfolio?

  • Your portfolio is all the investments you hold
  • Every portfolio is different
  • Your portfolio may change according to your goals and risk level
4 min read

A portfolio is simply your ‘collection’ of investments. All the investments you hold make up your portfolio.

Just as an artist may have a portfolio of their work, representing everything they’ve made, your portfolio is all the investments you’ve bought that you currently hold.

You can have stocks, bonds, funds, real estate, and cash in a portfolio.

The investments in your portfolio may depend on your goals, age, beliefs, and appetite for risk. A solid foundation of diversified funds that you can buy and hold for the long term is an important start, and then you can build out your portfolio to reflect your interests and changing goals.

Creating a portfolio is about balance. In the next guide, we’ll talk more about risk, which is an essential part of creating any portfolio.

As you get more and more comfortable with investing (and all the terms and ideas involved with it) you’ll start to learn how you may want to change your portfolio over time.
