Tom and Ben both intend to invest $50,000 (that they have each received from an inheritance) in Macquarie Group shares that are currently trading at $50 per share. Tom prefers an unlevered investment, whereas Ben decides to borrow a further $50,000 at 10% pa so that he can initially purchase $100,000 in shares. Compare the potential returns and risks for a one year investment (ignoring transaction costs and taxes) for two investors assuming firstly, the share price increases from $50 to $60, and secondly, the share price falls from $50 to $40.
