Stock Prices
Let's say that a new corporation is created and in its IPO it raises $20 million by selling one million shares for $20 a share. The corporation buys its equipment and hires its employees with that money. In the first year, when all the income and expenses are added up, the company makes a profit of $1 million. The board of directors of the company can decide to do a number of things with that $1 million:
It could put it in the bank and save it for a rainy day.
It could decide to give all of the profits to its shareholders, so it would declare a dividend of $1 per share.
It could use the money to buy more equipment and hire more employees to expand the company.
It could pick some combination of these three options. If a company traditionally pays out most its profits to its shareholders, it is generally called an income stock. The shareholders get income from the company's profits. If the company puts most of the money back into the business, it is called a growth stock. The company is trying to grow larger by increasing the amount of equipment and the number of people who run it.
Stock Prices: Income vs. GrowthThe price of an income stock tends to stay fairly flat. That is, from year to year, the price of the stock tends to remain about the same unless profits (and therefore dividends) go up. People are getting their money each year and the business is not growing. This would be the case for stock in a single restaurant that distributes all of its profits to the shareholders each year.
Let's say that the single restaurant decides, for several years, to save its profits, and eventually it opens a second restaurant. That is the behavior of a growth company. The value of the stock rises because, when the second restaurant opens, there is twice as much equipment and twice as much profit being earned by the company. In a growth stock, the shareholders do not get a yearly dividend, but they own a company whose value is increasing. Therefore, the shareholders can get more money when they sell their shares -- someone buying the stock would see the increasing book value of the company (the value of the buildings, equipment, etc.) and the increasing profit that the company is earning and, based on these factors, pay a higher price for the stock.
In a publicly traded company, all of the financial information about the company is public. The Securities and Exchange Commission (SEC) is in charge of collecting this information and making it available to investors. Shareholders also use a number of other indicators to determine how much a stock is worth. One simple indicator is the price/earnings ratio. This is the price of the stock divided by the earnings per share. There are all sorts of indicators like these, as well as a great deal of other financial information available on any stock. You can look up all of it on the Web in thousands of different places -- see the links at the end of this article for details.
Stock Prices
A Stock Exchange
A Stock ExchangeIf I am a private citizen who owns a restaurant, and I am selling my restaurant stock to other private citizens in the community, I might do the whole transaction by word-of-mouth, or by placing an ad in the newspaper. This makes selling the stock easy for me. However, it creates a problem down the line for investors who want to sell their stock in the restaurant. The seller has to go out and find a buyer, which can be hard. A "stock market" solves this problem.
Stocks in publicly traded companies are bought and sold at a 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.
The exchange makes buying and selling easy. You don't have to actually travel to New York to visit the New York Stock Exchange -- you can call a stock broker who does business with the NYSE, and he or she will go to the NYSE on your behalf to buy or sell your stock. If the exchange did not exist, buying or selling stock would be a lot harder. You would have to place a classified ad in the newspaper, wait for a call and haggle on a price whenever you wanted to sell stock. With an exchange in place, you can buy and sell shares instantly.
The stock exchange has an interesting side effect. Because all the buying and selling is concentrated in one place, it allows the price of a stock to be known every second of the day. Therefore, investors can watch as a stock's price fluctuates based on news from the company, media reports, national economic news and lots of other factors. Buyers and sellers take all of these factors into account. So, for example, when the FAA (Federal Aviation Administration) shut down the company ValuJet for a month in June 1996, the value of the stock plummeted. Investors could not be sure that the airline represented a going concern and began selling, driving the price down. The asset value of the company acted as a floor on the share price.
The price of a stock also reflects the dividend that the stock pays, the projected earnings of the company in the future, the price of tea in China (especially Lipton stock) and so on.
UNDERPRICING AND LONG
UNDERPRICING AND LONG-RUN PERFORMANCE OF SHARE ISSUE PRIVATIZATIONS IN THE EGYPTIAN STOCK MARKETMohammed Omran11Arab Academy for Science & Technology, College of Management & Technology, Egypt Arab Monetary Fund, Economic Policy Institute, United Arab Emirates1Arab Academy for Science & Technology, College of Management & Technology, Egypt Arab Monetary Fund, Economic Policy Institute, United Arab EmiratesI would like to thank the executive editor, William T. Moore, and the referee, William Megginson, for their constructive and insightful comments and suggestions. The views expressed in this paper are those of the authors and do not necessarily reflect the views of the Arab Monetary Fund.AbstractThe underpricing of initial public offerings (IPOs) is documented for 53 share issue privatizations in Egypt between 1994 and 1998. Over several intervals (up to five years), I find mixed results: share issue privatizations sustain their positive performance and provide investors with positive abnormal returns over a one-year period; however, my results document negative abnormal returns over three- and five-year horizons. The initial excess returns are determined by ex ante uncertainty and oversubscription, whereas the aftermarket abnormal returns over a one-year period are driven by ex ante uncertainty and the price-earnings ratio. However, over three- and five-year periods, abnormal returns are significantly affected by initial excess returns, the price-earnings ratio, and, to a lesser extent, oversubscription. The empirical findings are consistent with IPO markets in which investors are overoptimistic about the performance of these issues but grow more pessimistic over time.
