答案和详解如下： 6.A put on Stock X with a strike price of $40 is priced at $3.00 per share; while a call with a strike price of $40 is priced at $4.50. What is the maximum per share loss to the writer of the uncovered put and the maximum per share gain to the writer of the uncovered call?
| Maximum Loss
to Put Writer | Maximum Gain
to Call Writer |
A) $37.00 $35.50 B) $37.00 $4.50 C) $40.00 $4.50 D) $40.00 $40.00 The correct answer was B) The maximum loss to the uncovered put writer is the strike price less the premium, or $40.00 - $3.00 = $37.00. The maximum gain to the uncovered call writer is the premium, or $4.50. 7.Suppose the price of a share of Stock A is $100. A European call option that matures one month from now has a premium of $8, and an exercise price of $100. Ignoring commissions and the time value of money, the holder of the call option will earn a profit if the price of the share one month from now: A) increases to $106. B) decreases to $94. C) increases to $110. D) decreases to $90. The correct answer was C) The breakeven point is the strike price plus the premium, or $100 + $8 = $108. Any price greater than this would result in a profit, and the only choice that exceeds this amount is $110. 8.Jimmy Casteel pays a premium of $1.60 to buy a put option with a strike price of $145. If the stock price at expiration is $128, Casteel’s profit or loss from the options position is: A) $1.60. B) $18.40. C) $15.40. D) $128.00. The correct answer was C) The put option will be exercised and has a value of $145-$128 = $17 [MAX (0, X-S)]. Therefore, Casteel receives $17 minus the $1.60 paid to buy the option. Therefore, the profit is $15.40 ($17 less $1.60). 9.Al Steadman receives a premium of $3.80 for shorting a put option with a strike price of $64. If the stock price at expiration is $84, Steadman’s profit or loss from the options position is: A) $16.20. B) $20.00. C) $3.80. D) $23.80. The correct answer was C) The put option will not be exercised because it is out-of-the-money, MAX (0, X-S). Therefore, Steadman keeps the full amount of the premium, $3.80. 10.Linda Reynolds pays $2.45 to buy a call option with a strike price of $42. The stock price at which Reynolds earns $3.00 from her call option position is: A) $2.45. B) $47.45. C) $3.00. D) $42.00. The correct answer was B) To earn $3.00, the stock price must be above the strike price by $3.00 plus the premium Reynolds paid to buy the option ($42.00+$3.00+$2.45). |
