Answer:
-21%
Step-by-step explanation:
Initial share price = $50
Share price after 1 year = $46
net return = (200 x $46) - $10,000 - ($5,000 x 5%) = $9,200 - $10,000 - $250 = -$1,050
rate of return of margined position = -$1,050 / $5,000 = -0.21 = -21%
when you operate on the margin, your earnings can increase or decrease dramatically. In this case, an 8% price decrease resulted in a 215 lose.
