Expiry Price =100, Stock price=107, time to expiry=15days, discount rate=0.05, del=0.06
d1=ln 107/100+15/360(0.05+0.06/squrt.2)/0.06.sqirt/15=.072/.232=0.31.
If I have 100 stocks to hedge I sell 31 calls from the above formula for hedge ratio d1 for say $7 price of option today and if price move to $100,
gain from writing call = 31x7 = 217
loss in stock = 7x100= - 700 with a downside loss of $483.
If this is the case then how can d1 be the hedge
ratio if it cannot protect against downside risk. This is te 'in the money' case.
Suppose if the option is 'out of money' similar result happens without any degree of protection for downside risk.
