Final answer:
The percentage return on invested capital is 42.98%.
Step-by-step explanation:
To calculate the percentage return on invested capital, we need to consider the initial investment, interest paid on the margin loan, dividends received, and the current market value of the stock.
Initial investment = 250 * £88.00 * 0.65 = £14,300
Dividends received = 250 * £0.5 = £125
Interest paid on the margin loan = £60
Current market value of the stock = 250 * £81.50 = £20,375
Total return = Dividends received - Interest paid + (Current market value of the stock - Initial investment)
= £125 - £60 + (£20,375 - £14,300)
= £65 + £6,075
= £6,140
Percentage return on invested capital = (Total return / Initial investment) * 100
= (£6,140 / £14,300) * 100
= 42.98%
