How does buying stocks work

By purchasing shares of a stock, you become an investor in the underlying company. 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.

Think of stock market trading like an auction, with some investors 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, and the price will move 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 possible to always buy or sell a stock you own.

That's where market makers come in. 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. 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, so how can brokers buy and sell stocks in your account instantaneously?

To make sure there's always a marketplace for stocks on an exchange and investors can choose to buy and sell shares immediately whenever they want to during market hours, individuals known as market makers act as intermediaries between buyers and sellers.

Here's a rundown of what investors should know about the process:. The main reason for using the market maker system as opposed to simply letting investors buy and sell shares directly to one another is to be sure there is always a buyer to match with every seller and vice versa. If you want to sell a stock, 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, which 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, or, more commonly, this can be an online broker -- say, TD Ameritrade or Fidelity -- that processes the entire transaction electronically.

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. Indexes are a convenient way to discuss an approximation of what is happening in the market, but 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.

A stock is an ownership share in a business, and literally thousands of them trade on a stock exchange, allowing anyone — even beginners — to become a part owner in the company. The broker lets you purchase and sell stock, holds the shares for you in an account and collects any dividends that are paid.

As economists like to say, there ain't no such thing as a free lunch. Though recently many brokers have been racing to lower or eliminate commissions on trades, and ETFs offer index investing to everyone who can trade with a bare-bones brokerage account, all brokers have to make money from their customers one way or another.

In most cases, your broker will charge a commission every time you trade stock, either through buying or selling. Some brokers charge no trade commissions at all, but they make up for it in other ways.

There are no charitable organizations running brokerage services. Depending on how often you trade, these fees can add up and affect your profitability.

Besides the trading fee to purchase a mutual fund , there are other costs associated with this type of investment. Mutual funds are professionally managed pools of investor funds that invest in a focused manner, such as large-cap U. There are many fees an investor will incur when investing in mutual funds. One of the most important fees to consider is the management expense ratio MER , which is charged by the management team each year based on the number of assets in the fund.

The MER ranges from 0. But the higher the MER, the more it impacts the fund's overall returns. You may see a number of sales charges called loads when you buy mutual funds. Some are front-end loads, but you will also see no-load and back-end load funds. Be sure you understand whether a fund you are considering carries a sales load prior to buying it. Check out your broker's list of no-load funds and no-transaction-fee funds if you want to avoid these extra charges. For the beginning investor, mutual fund fees are actually an advantage compared to the commissions on stocks.

The reason for this is that the fees are the same regardless of the amount you invest. The term for this is called dollar-cost averaging DCA , and it can be a great way to start investing.

Diversification is considered to be the only free lunch in investing. In a nutshell, by investing in a range of assets, you reduce the risk of one investment's performance severely hurting the return of your overall investment. You could think of it as financial jargon for "don't put all of your eggs in one basket. In terms of diversification, the greatest amount of difficulty in doing this will come from investments in stocks.
