An investor owns 1,000 shares currently priced at $40 and buys 1,000 put options with an exercise price of $38 at a premium of $2 each. The options are European. At expiration, the share price is $30. The investor's net position value per share, including the premium paid, is closest to:

The protective put gives a floor at the exercise price of $38. The share is worth $30 and the put pays $8, totaling $38. After deducting the $2 premium, the net value is $36 per share. Ignoring the put leaves $30, and ignoring the premium gives $38.

  1. A$30
  2. B$36Correct
  3. C$38

Explanation

At expiration the share is worth $30 and the put pays 38 - 30 = $8, giving $38 per share. Subtracting the $2 premium gives $36 net. The $38 figure ignores the premium, and $30 ignores the put payoff altogether.
