15. Suppose you recently opened an account with Ameritrade, Inc., an online broker. You have decided to purchase shares of either Johnson & Johnson (a pharmaceutical company) or PepsiCo (the parent company of Pepsi and Frito-Lay). For a comparison of the two companies go to http://finance.yahoo.com and in the space where it says Get Quotes enter the letters JNJ and PEP, which are the respective symbols for the two companies. Click on Go and you should receive some current information about the selling price of the two stocks. To the right of this information click on More and then click on Analyst Opinion. Here you will find information from stock analysts evaluating these stocks. Brokers rate the stock a 1 if it is a strong buy and a 5 if it is a strong sell.
