Part 1: Calculate Margin Return:
Margin Return %
= [((Ending Value – Loan Payoff) / Beginning Equity Position) – 1] × 100
= [(([$34 × 1,000] – [$32 × 1,000 × 0.60]) / ($32 × 0.40 × 1,000)) – 1] × 100
= 15.6%
Alternative (Check): Calculate the all cash return and multiply by the margin leverage factor.
[(34,000 – 32,000) / 32,000] × [1 / 0.40] = 6.35% × 2.5 = 15.6%
Part 2: Calculate Margin Call Price:
The formula for the margin call price is:
Margin Call = (original price) × (1 - initial margin) / (1 - maintenance margin)
= $32 × (1 - 0.40) / (1 - 0.25) = approximately $25.60
