How do bond pricing formulae differ between the US, UK and the Euro zone?

This is a great question, given that it can be hard to answer questions like this generally. – Shane May 30 '10 at 14:37

What's the difference between volatility and variance?
added by Jaydles May 27 '10 at 3:13
link
This question seems too basic to me, and might be better suited to the statistics site? It could be rephrased as something like "why is volatility more commonly used as a risk measure than variance", or something along that line, in which case it would be more relevant. – Shane Jun 1 '10 at 14:43

This might be too basic/general? – Shane Jun 1 '10 at 13:52
Probably another "move the turtle in Logo" question, but I'm down with it. It's topical and as long as duplicates get deleted seems OK by me. – JD Long Jun 2 '10 at 14:28

This is not basic at all! Delta hedging seems basic on the surface, but it's a deep problem in itself. – quant_dev Jun 12 '10 at 10:04

deep perhaps, but too general for sure. – jbr Jul 5 '10 at 19:19

What is Value at Risk and how is it calculated?
added by Jason Punyon♦ Jun 1 '10 at 20:20
link
Not sure, but this question may be a little too basic, and there are several different ways to calculate VaR. See my related question: area51.stackexchange.com/proposals/117/…. – Shane Jun 1 '10 at 20:28

What are the pros/cons to using cointegration vs correlation when trading pairs in short timeframes (HFT)?
added by jbr Jun 26 '10 at 17:55
link
Always? This seems like it could be subjective given the way the question is phrased. – Shane Jul 7 '10 at 8:03
Yes, the question is unclearr. I was particularly thinking about high frequency timeframes. Is cointegration relevant in those timeframes? The main advantage for cointegration is that it captures long term relationships and correlation is unstable and short term. But, is that a reason to prefer correlation in shorter timeframes? – jbr Jul 11 '10 at 17:19
Do you want to edit your question to reflect that you're referring specifically to HFT? – Shane Jul 11 '10 at 17:43

this is obviously a beginner question, but it is something exclusively of interest to pro quants – Joel Spolsky♦ May 25 '10 at 21:00
Weird. I thought it would be too basic for quants which is why I proposed it... – Michael Pryor May 27 '10 at 17:16
@Joel this is a tough one. It is a basic question (in options theory) but obviously a specialized area. Does this mean "what is a put option?" also qualifies? – cletus May 27 '10 at 23:13
I agree with @cletus; this might be too basic, although it's a fine line. I would be happy for basic questions to exist so long as they don't drive away a community of experts in the process. – Shane May 30 '10 at 14:26
