Answer:
a. Are the stock and the rights correctly priced on the ex-rights day?
stock price at ex-right = [(3 x $80) + $53] / 4 = $73.25
cost of ex-right = $80 - $73.25 = $6.75
the rights are underpriced since they are sold at $2, and they should sell at $6.75
b. Describe a transaction in which you could use these prices to create an immediate profit.
You can purchase 3 rights at $6 and then pay subscription price ($53) and you would have an stock at $59. Your profit = $65 - $59 = $6 per stock.
