Compare two companies, NIKE and Walmart with the final result telling me which stock you would recommend? Which stock is the better investment based on your own analysis? Tell a summary of each company describing their industry, the products they sell, the parts of the world they do business in, and the competition. Also tell about some of the potential risks that are apparent for each company. Also, how did they fare in the Covid pandemic? 4 to 6 paragraphs is sufficient.
