Rob McGowan collects data from General Motors, General Electric,
Oracle, and Microsoft. His professor seeks to form a portfolio
using these stocks.
Provide a quick rundown of the issues that the professor face
while creating his portfolio. Discuss what your goals and objective
would be if you were creating this portfolio, how can you “add
value”. Think about issues such as efficiency, risk-return, and how
to add value. Include a recommendation of a portfolio make-up
(weights, or even suggestions of...
