Part (a)Gross profit or loss on put option | ||||||
Cachita expects Yen to fall. So put option on yen has been taken. So we will calculate strike price and spot price for Yen. | ||||||
Spot rate 1$ = | ¥120.00 | or | ¥1.00 | = 1/120 = | $0.008333 | |
Strike price 1$ = | ¥125.00 | or | ¥1.00 | = 1/125 = | $0.008000 | |
Premium on put option = | $0.00003 | or | ||||
Total premium paid on contract = ¥1,000,000 * 0.00003 | ||||||
$30.00 | ||||||
Spot rate at end of 90 days 1$ = 140 | or | ¥1.00 | =1/140 = | $0.007143 | ||
Put option value at expiration are equal to Strike price minus spot rate, if Currency spot rate is less than strike price, option shall be exercised. | ||||||
If spot rate is more than strike pirce, Option shall not be exercised. So value of put option shall be zero. | ||||||
Value of Put option = Strike price - Spot rate (Subject to 0) | ||||||
$0.008000 | $0.007143 | |||||
$0.000857 | ||||||
Contract size is ¥1,000,000 | ||||||
So, Gross profit = 0.00086 * 1000000 | ||||||
$857.14 | ||||||
So, gross profit is $857.14 | ||||||
Net profit or loss on put option | ||||||
Net profit = Gross profit - premium paid | ||||||
857.14 - 30 | ||||||
$827.14 | ||||||
So, Net profit is $827.14 | ||||||
