Investments in Companies

$50, 000 will be invested and I thought about it over the weekend which companies I would like to invest in well a couple of them are Target, Apple, Corinthian Colleges, Coca Cola, Pepsi soft drinks, and an oil company or that company that teacher invested into that made him so much money. The companies that i am thinking of the most they cost is like $60 -$65. The reason that I picked Pepsi because I remember that Pepsi is on a lot of college campuses and they make tons of money off of college students. Also if the companies I choose wont make a lot of money than I'll trade it. Also my sisters job company Price Water House Coopers.
