1. When we write a call, we have given the other party the right
to demand payment if the stock price rises above the strike price.
In this case, the price had fallen to $48 when the strike price was
$51 and hence the call shall not be exercises.
However the person shall suffer a loss on the original share as
price fell from $50 to $48.
Per share loss thus is $48-$50+%0.5
= - $ 1.5
