OPTION PRICING DELTA HEDGE

RRania9y ago
hello sir , i was watching the 2nd part of your lecture on option pricing and couldnt understand one thing that u said that DELTA = N(D1) BUT WHAT i know delta value is option price change/ Share price change I cant understand how nd1 represents option price change? and second thing i couldnt understand why in example 5, martin could have bought 1000 shares to hedge the risk 4080 options?

I think that maybe you need to watch all of the option pricing lectures again, because I do explain. If, for example, Nd1 was equal to 0,2. then it would mean that in the short term that if Pa (the current market price) were to change by $1 then the current option price would change by 0.2 x $1 = $0.20. Example 5 is using exactly the same principle.
