Stock Market

The stock market appears in the news every day. You hear about it any time it reaches a new high or a new low, and you also hear about it daily in statements like "The Dow Jones Industrial Average rose 2 percent today, with advances leading declines by a margin of..."
Obviously, stocks and the stock market are important, but you may find that you know very little about them. What is a stock? What is a stock market? Why do we need a stock market? Where does the stock come from to begin with, and why do people want to buy and sell it? If you have questions like these, then this article will open your eyes to a whole new world!
Determining Value
Let''s say that you want to start a business, and you decide to open a restaurant. You go out and buy a building, buy all the kitchen equipment, tables and chairs that you need, buy your supplies and hire your cooks, servers, etc. You advertise and open your doors.
Let''s say that:
You spend $500,000 buying the building and the equipment.
In the first year, you spend $250,000 on supplies, food and the payroll for your employees.
At the end of your first year, you add up all of the money you have received from customers and find that your total income is $300,000. Since you have made $300,000 and paid out the $250,000 for expenses, your net profit is:
$300,000 (income) - $250,000 (expense) = $50,000 (profit)
At the end of the second year, you bring in $325,000 and your expenses remain the same, for a net profit of $75,000. At this point, you decide that you want to sell the business. What is it worth?
One way to look at it is to say that the business is "worth" $500,000. If you close the restaurant, you can sell the building, the equipment and everything else and get $500,000. This is a simplification, of course -- the building probably went up in value, and the equipment went down because it is now used. Let''s just say that things balance out to $500,000. This is the asset value, or book value, of the business -- the value of all of the business''s assets if you sold them outright today.
Selling SharesIf you keep the restaurant going, it will probably make at least $75,000 this year -- you know that from your history with the business. Therefore, you can think of the restaurant as an investment that will pay out something like $75,000 in interest every year. Looking at it that way, someone might be willing to pay $750,000 for the restaurant, as a $75,000 return per year on a $750,000 investment represents a 10-percent rate of return. Someone might even be willing to pay $1,500,000, which represents a 5-percent rate of return, or more if he or she thought that the restaurant''s income would grow and increase earnings over time at a rate faster than the rate of inflation.
The restaurant''s owner, therefore, will set the price accordingly. You might price the restaurant at $1,500,000. What if 10 people come to you and say, "Wow, I would like to buy your restaurant but I don''t have $1,500,000." You might want to somehow divide your restaurant into 10 equal pieces and sell each piece for $150,000. In other words, you might sell Shares in the restaurant. Then, each person who bought a share would receive one-tenth of the profits at the end of the year, and each person would have one out of 10 votes in any business decisions. Or, you might divide ownership up into 1,500 shares and sell each share for $1,000 to make the price something that more people could afford. Or, you might divide ownership up into 3,000 shares, keep 1,500 for yourself, and sell the remaining shares for $500 each. That way, you retain a majority of the shares (and therefore the votes) and remain in control of the restaurant while sharing the profit with other people. In the meantime, you get to put $750,000 in the bank when you sell the 1,500 shares to other people.
 stock market (also known as a stock exchange). The New York Stock Exchange (NYSE) is an example of such a market. In your neighborhood, you have a "supermarket" that sells food. The reason you go the supermarket is because you can go to one place and buy all of the different types of food that you need in one stop -- it''s a lot more convenient than driving around to the butcher, the dairy farmer, the baker, etc. The NYSE is a supermarket for stocks. The NYSE can be thought of as a big room where everyone who wants to buy and sell shares of stocks can go to do their buying and selling.
