Basic fixed income question: the meaning of "one month ahead"

As a fixed income novice, I am trying to wrap my head around the conversion of US Treasury par yield rates to spot rates (zero-coupon rates) using exact US market conventions.  Take the par yield curve here:  Resource Center | U.S. Department of the Treasury If you want to associate a maturity date ...

Re: Stupid question of the day

Thank you <3 William Gibson used it in Neuromancer, and his English has always felt so snobbish to me! Hmm. He is probably my favorite author, and more for his turn of phrase than the storylines. His language is certainly rich, but I don’t know that I quite get snobbish. I think he may have peaked ...

Re: Random Republican WINGNUTS (or RRWs as they are affectionately known as)

This may be a mistake, as in it should probably be a new thread. But, anyway, the bleeding head Ron DeSantis, the very Trumpian governor of Florida, who is now trying to out-Trump Trump, is pushing a law that would ban Florida universities from teaching any courses with a curriculum based on theore...

Re: Equity styles for higher cross-sectional moments

1. Why are the most successful (publicly offered) funds (in terms of long-term performance) low cost, cap-weighted index funds and *not* long-short funds? 2. Let's say "the bottom quartile will basically all go to zero". I suspect that will be due to failed clinical trials. If you could pr...

Re: Alaska - Call of the Wild

Reports I've seen all say there were balloons involved, maybe metallic balloons. Fire enough bullets and the thing will start to descend, and eventually be low enough to grab it. Tom Cruise could do it.

Re: Fund group internal transfers at unfair prices

No, but if the manager is SEC-regulated this guide may be of interest. 
(This guide is apparently the product of a law firm probably looking to earn whistleblower fees, so keep that in mind).

What is your evidence besides the disparate performance of various funds?

Skip ahead to 1:40. Unless you're a fan of Don Cornelius.
Nice one!

Re: Pricing Option with Knock Outs on Realised Volatility

You might try Gatheral's simple lognormal model
In the lognormal model, given volatility and variance swap prices, the entire distribution is specified and we may price any claim on quadratic variation!

Re: Hunting the Dirac Delta

You need delta or actually its derivative? I have now no issues with delta nor its derivative. BTW p is transition probability, p(t = 0) = delta. the Q can I write FPE in verry nice compact form and what are the advantages p_t = (A (B p_x))_x it's just another PDE. You should be able to always tran...

Re: Hunting the Dirac Delta

There is an example of using my non-smooth suggestion with NDSolve (including code) in my Vol II book, pages 462-464. It works quite well, as Fig 10.5 there shows. This looks very good, Alan. I reckom NDSolve (using Bulisch-Stoer) can handle many kinds of pesky deltas: 1.  avoiding oscillations and...
