Why Apple Stock Jumped on Monday
Numerous reports were decidedly bullish for the iPhone maker.
You may have heard that investing in stocks can be a great way to create wealth over time. That's certainly true. But do you really know how the stock market works? Do you know what makes a stock market different from a stock exchange or stock index? Do you know what a stock is?
If you answered no to any of these, you aren't alone. Here's a rundown of the basics of stock markets, stock exchanges, and stock indexes.
Before we get into stock markets, you need to understand stocks and how they work on a basic level. Here are a few basic concepts that can help new investors understand how the stock market works.
Stocks, also known as equities or publicly traded companies, represent ownership interests in businesses that choose to have their shares available to public investors.
A share of stock represents an ownership interest in a company. If you buy a share of Apple (NASDAQ:AAPL), you own a small part of the business and get to share in the company's success. In other words, instead of being owned by an individual or a private group, some companies choose to "go public." This means that anyone can become a part owner by purchasing shares of the company's stock.
How does the stock market work? There are entire books explaining the stock market, and there's too much to explain in a few paragraphs. That said, you don't need to get too deep into the weeds to gain a good basic understanding of the stock market. Stock markets facilitate the sale and purchase of these stocks between individual investors, institutional investors, and companies.
The vast majority of stock trades take place between investors. If you want to buy shares of Microsoft (NASDAQ:MSFT) and hit the "buy" button through your broker's website, you are buying shares that another investor has decided to sell -- not from Microsoft itself. By purchasing shares of a stock, you become an investor in the underlying company.
A stock's price is governed by supply and demand. If a lot of people want to own part of a certain company, then that company's stock price rises.
Stock prices on exchanges are governed by supply and demand, plain and simple. At any given time, there's a maximum price someone is willing to pay for a certain stock and a minimum price someone else is willing to sell shares of the stock for. These are known as the bid and ask prices, respectively. Think of stock market trading like an auction. Buyers are constantly bidding for the stocks that other investors are willing to sell.
If there is a lot of demand for a stock, investors will buy shares quicker than sellers want to get rid of them. This can move the price higher. On the other hand, if more investors are selling a stock than buying, the market price will drop.
Taking it a step further, it's important to consider how it's almost always possible to buy or sell a stock you own. That's where market makers come in.
One extremely important concept when it comes to understanding the stock market is the idea of a market maker. Specifically, there aren't always buyers to match up with sellers of stocks. However, stock trades typically go through in seconds. How can brokers buy and sell stocks in your account instantaneously?
Individuals known as market makers act as intermediaries between buyers and sellers. This ensures there's always a marketplace for stocks on an exchange and that investors can choose to buy and sell shares immediately whenever they want during market hours. Here's a rundown of what investors should know about the process:
Because of market makers, you'll never have to wait to sell stocks at their full market value. You don't need to wait until a buyer wants your exact number of shares -- a market maker will buy them right away.
Investors must carry out the transactions of buying or selling stocks through a broker. In a nutshell, a broker is simply an entity licensed to trade stocks on a stock exchange. A broker may be an actual person whom you tell what to buy and sell. More commonly, this is an online broker -- say, TD Ameritrade or Fidelity -- that processes the entire transaction electronically.
When you buy a stock, here's the simplified version of how it works:
When someone says "the market is up" or that a stock "beat the market," they are usually referring to a stock index.
You've probably heard statements such as, "The market is up," or that a stock "beat the market."
Often when discussing the stock market, people generalize "the market" to a stock index. Stock indexes, such as the S&P 500 or the Dow Jones Industrial Average, are a representation of the performance of a large group of stocks or a particular sector. These are used as a benchmark to compare the performance of individual stocks or an entire portfolio. For example, the S&P 500 index tracks the performance of 500 of the largest publicly traded companies in the U.S.
Indexes are a convenient way to discuss an approximation of what is happening in the market. However, it's important to understand that the major stock indexes you see on TV and in the news do not fully represent the entire stock market.
There are three different terms here with similar and often misunderstood meanings. A stock market refers to the process and facilitation of investors buying and selling stocks with one another. A stock exchange is the actual intermediary that connects buyers with sellers, such as the New York Stock Exchange (NYSE). A stock index is a numerical representation of a group of stocks that is used to track their collective performance.
Why is this important to understand? In short, knowing the basics of how stock markets work can help make you a better investor. You'll understand why your investments can be bought and sold at a second's notice. And you'll also understand that the market works like an auction system, and prices are governed by supply and demand – not just the underlying business fundamentals.
