compare the two companies of Walmart and NIKE. Tell me the history and the story behind both companies. What products do they makes and what are their markets? Who are their competitors? In which countries do they do business - would they be impacted by changing currencies. What are their growth prospects? How were they impacted by the current recession? Do they pay a dividend? If yes, what is the 5 year change in the dividend? What is the P/E ratio? What does this mean and is the stock cheap, rich, or fairly priced?
