Recently, you went to a restaurant for a weekend lunch. You saw your friend sitting with a nave person talking about investment in the share market. You heard that the person was telling your friend that the company XYZ's share was undervalued due to the effect of COVID19 and insisting on your friend for investing in XYZ's share, saying the investment would generate a positive NPV. As a finance student, how could you help your friend make an informed decision about investment in company XYZ?.
