I noticed that in order to reply sometimes I had to code it in excel or derive the equations, read the background material etc, took a lot of time and then, also, I did not have access to certain parts of the...

@Hend, That is awesome. Thanks.

What are the advantages of pursuing CFA? What type of jobs become open to you? How is this compared to MBA?

Correction: even for multi-state, multi-year model, binomial distribution should hold once the marginal default rate for that year/state are determined - because from that particular state it can either default or not, just 2 states. Regards.

Hend, a good question, seemed very ordinary though. ShaktiRathore elucidated with details. The reason that the MP (monetary policy) and FP(Fiscal Policies ) are under different controls, I think, is because of purely technical issues. Federal Reserve, holder of MP, was created in 1913 in...

It seems, d2 changes sign from positive to negative as relationship of r changes from less than to more than sigma^2/2. so if the vol increases or r decreases the d2 will shift toward negative. Here, it does not change the answer any. Thanks.

as T->infinity, exp(-rT) ->0 d1, d2 -> +infinity N(d1)->1 and N(d2)->1 c=S N(d1) -K N(d2) exp(-rT) ->S <== so call will become equal to asset price. N(-d1)->0 and N(-d2) -> 0 ; p=K exp(-rT) N(-d2) - S N(-d1) -> 0 <=== so the put will tend to be zero put call parity holds, as c - p= S - K...
