### Dumb/interesting Black-Scholes question

<t>Antonio, the point here is that the t in question is not the time to expiry of the option (T), but rather the time elapsed since inception of the option. Thus, T > t >0 (sorry for a stupid typo in my original post)... So, and it's the same thing, I am looking for an expression for MAX(moneyness(t...

### Dumb/interesting Black-Scholes question

<t>My question is quite possibly stoopid, but here goes...In a simple Black-Scholes world, for a simple option, if I am trying to compute E[max(BSDelta(t))], where T < t < 0 with T as time to expiry. What kind of a function of t, do you expect this thing to be? It should be a simple thing, but someh...

### perfect asset swap

I might be able to help if you be a bit more specific... What type of asset swap we're talking about?

### Comparing Index-Linked Bonds with different indexation lag

<t>renikus, sorry for the delay...You're generally right, i.e. asset swaps are the best way to look at these buggers. However, there's many types of asset swaps, par/par, proceeds etc. Of those the best method (it makes the least number of assumptions and is the most accurate) is to use z-spreads, w...

### Comparing Index-Linked Bonds with different indexation lag

<t>Hehe, let me guess, you're looking at the old gilts vs the new Canadian-style ones? I think the right way is to look at the actual mechanics of the calculation for the different lags. You can then calculate all the characteristic of the bonds, yields, carry, bei vs swap or appropriate nominal bon...

### Did I price this Knock In Knock Out product correctly

Ain't this just a double-barrier option? What's K in relation to S(H) and S(L)?

### Implied volatility of short sterling options

That "indicative ATM volatility" is only valid for the ATM straddle, in which case, I am pretty sure, it is computed with simple Black-Scholes.If you describe your logic in a bit more detail, I might be able to help you some more...

### Do dealers price convexity into longer-dated IMM FRAs

<t>Good dealers certainly do price convexity into FRAs.This is not to say that long-dated sterling FRAs are the most liquid of instruments (I've only done a trade like that once and it was more from necessity than by choice. The one time I did, a dealer I would consider good gave me a mkt about 1.5 ...

### Convexity of swap flies

<t>A couple of questions to the masters out there, if they, in their infinite wisdom, be so inclined...1. Convexity measure for swaps seems like it should be calculated in the exact same boring manner as it is for bonds. Any particular reasons you can think of why it shouldn't be? Is it reasonably s...

### Cash and Physically settlement Options

<t>Cash-settlement for swaption expiries is indeed the EUR (and GBP) convention. There's two different calculation methods, too: IRR and PVBP. In pnl terms it makes a difference whether you cash-settle a swaption (and exchange delta at the fixing) or expire into a physical swap, because even the mor...

### Double digital

I know... I think these little buggers are also called "two-asset cash-or-nothing options". Basically given two assets S1 and S2 and two strikes K1 and K2, you receive a fixed payment if S1 < K1 and S2 < K2 (this is a considered a put).

### Double digital

<t>I was just wondering if anyone knows of any work (papers, etc) on pricing double digital options. Apart from the short article by Drezner on numerically estimating the bivariate normal distribution integral (which is a useful gimmick), I don't know of anything, but then again I could just be an i...
