Intro to the stock market

In our country there are three stock exchanges that investors can use to purchase and sell shares of different companies. These three exchanges are: Dow Jones, Nasdaq, and S&P 500. Of these three the Dow Jones has the most volume of shares circulating the exchange. Companies such as American Express, Microsoft, Walmart, and Exxon Mobil. The Dow Jones has hit a record high for 2009 in the recent days at around $10,500. Today alone the exchange in total grew 65 points. The Nasdaq trades at around $2,200 and has gone as far down as $1,200 in the past year. Today the Nasdaq Composite fell .55 points. The S&P 500 trades at $1,100 and has ranged from $660 to $1,200. Choosing the right company to invest to can be very difficult with the amount of companies that are available to be sold and bought by the public. Penny stocks are especially difficult to predict because the price could fall very easily or rise 150% or more in only a day.
