Customers trading quantities over 500 shares can often achieve more price improvement. Fidelity’s portfolio analysis feature lets you link outside accounts, as well as any cryptocurrency you hold at Coinbase, to give you a picture of your overall financial health.

Where Can I Learn to Trade?

While learning to trade and invest in the stock market may seem intimidating, it is actually more simple than you would think. Fortunately, Investopedia has a wealth of information that can teach you the ins and outs of the markets. The following articles are great resources to get you on your way to being a successful investor:

Trading Terms to Know

To trade successfully, you should have an understanding of certain terms. Every new investor should become acquainted with the following terms:

  • Stock: A stock (also known as "shares" or "equity") is a type of security that signifies proportionate ownership in the issuing corporation. This entitles the stockholder to that proportion of the corporation's assets and earnings.
  • Price-to-Earnings Ratio – P/E Ratio: The price-to-earnings ratio (P/E ratio) is a ratio for valuing a company that measures its current share price relative to its per-share earnings (EPS). The price-to-earnings ratio is also sometimes known as the price multiple or the earnings multiple.
  • Market Capitalization: Market capitalization, commonly referred to as "market cap," refers to the total dollar market value of a company's outstanding shares. Market cap is calculated by multiplying a company's shares outstanding by the current market price of one share.
  • Dividend: A dividend is the distribution of reward from a portion of the company's earnings and is paid to a class of its shareholders.
  • Exchange-Traded Fund (ETF): An exchange-traded fund (ETF) is a collection of securities—such as stocks—that typically tracks an underlying index.
  • Bond: A bond is a fixed income instrument that represents a loan made by an investor to a borrower (typically corporate or governmental). A bond could be thought of as an I.O.U. between the lender and borrower that includes the details of the loan and its payments.
  • Mutual Fund: A mutual fund is a type of financial vehicle made up of a pool of money collected from many investors to invest in securities such as stocks, bonds, money market instruments, and other assets. Mutual funds are operated by professional money managers, who allocate the fund's assets and attempt to produce capital gains or income for the fund's investors.
  • Limit Order: A limit order is the use of a pre-specified price to buy or sell a security. For example, if a trader is looking to buy XYZ’s stock but has a limit of $14.50, they will only buy the stock at a price of $14.50 or lower. If the trader is looking to sell shares of XYZ’s stock with a $14.50 limit, the trader will not sell any shares until the price is $14.50 or higher.
  • Market Order: A market order is a request by an investor – usually made through a broker – to buy or sell a security at the best available price in the current market. It is widely considered the fastest and most reliable way to enter or exit a trade and provides the most likely method of getting in or out of a trade quickly. For many large-cap liquid stocks, market orders fill nearly instantaneously.

Things to Consider When Choosing an Online Broker

Once you have learned the basics of the stock market you can begin to think about choosing a broker. When choosing an online broker you'll need to consider these three important steps:

  1. Choose the type of brokerage account you need.
  2. Consider the features you want and their associated costs.
  3. Choose the brokerage that best fits your needs.

Step 1: In order to decide which broker works best for your needs, you first need to think about the different investing styles. Here are common investing styles used today:

You can check out exactly how these different methods work with our article on investment styles.

Step 2: It's very important to decide which features you will need in a broker. You should consider factors like educational materials, research tools, news access, and how their fees are structured to assess what works best for you. If you are beginner it could be best to focus less on their fees and more on what kinds of educational materials they offer. On the other hand, more experienced investors may want advanced charting features and the ability to back-test.

Step 3: Now that you have thought about which investment styles and features are suitable for you it's time to choose a broker. It's also important to keep in mind that fewer fees and commissions can also mean fewer features so it's best to research each platform before opening an account. Check out our guide to opening an online brokerage account for more guidance and information.
