You purchase 300 shares of HON at $89 per share on margin with 75% margin ratio (25% is financed by debt). If the price changes to $51.5 after 3 months (90 days), and the interest rate on the margin loan is 8%, what is your net percentage return on this position? Assume that your brokerage uses a 365 day convention for calculating daily interest rates, and that interest compounds daily. Enter answer in percents, positive for gains, negative for losses, accurate to 2 decimal places.
