Barbara purchased 100 shares of IBZ at 35 using a 60% initial
margin. Due to unexpected news the stock price drops the next day
to 25 and Barbara receives a margin call.
How much money does Barbara need to put on her account, if the
broker requires that she restores the % margin to the initial 60%
level?
Provide your answer rounded up to the next dollar. Show all
calculations with formulas.
Initial margin is a percentage of purchase price paid in cash or collateral. the remaining amount of purchase price is borrowed from broker.
Initial margin = (No. of shares purchased*purchase price per share)*initial margin percentage
Initial margin = (100*35)*60% = 3,500*60% = 2,100
so, amount borrowed is: Purchase price - Initial margin = 100*35 - 2,100 = 3,500 - 2,100 = 1,400
Total value of shares after price drop = no. of shares*price per share after drop = 100*25 = 2,500
value of initial margin after drop = Total value of shares after price drop - amount borrowed = 2,500 - 1,400 = 1,100
money needed to put in account = (Total value of shares after price drop*initial margin percent) - value of initial margin after drop
money needed to put in account = (2,500*60%) - 1,100 = 1,500 - 1,100 = 400
Barbara needs to put 400 on her account, if the broker requires that she restores the % margin to the initial 60% level.
