Q$4$e$.$ Calculate option price when stock moves $$950.$ How much of the total PnL of Q$4$d is from

option position, and how much is from the stock position? $(3$ points$)$

$($note: the TOTAL PnL from options and stocks should match the total PnL from delta and gamma$).$

Q$4$f$.$ If underlying moves down from $1000$ to $950,$ what is the new delta at stock price of $950$ for

your overall position? If you want to re$-$hedge to flatten the delta with underlying shares, what

trade do you need to do in the shares to achieve that? How many shares to trade? Long or short? $(2$

points$)$

Q$4$g$.$ What is the PnL from the delta and gamma when underlying moves from $1000$ to $1025,$

respectively? $(2$ points$)$

Q$4$h$.$ For Q$4$g$,$ how much of the total PnL is from option position, and how much is from stock

positions, when underlying moves from $1000$ to $1025?(2$ points$)$
