Newbie questions. What is Martingale Theory? How accurate is ARCH/GARCH? What is stochastic calculas?

<t>Through out time, a process can have drift, normally represented by (a) dt. However, a martingale is a zero-drift stochastic process. For example, Theta follows a martingale if the process follows the form d(Theta) = (Sigma) dz. (dz is a Wiener process). (Let me guess, you also want to know what ...

War against Iraq??

<t>I've just seen the news, some US ex-attorney general (don't ask me who) made a few points:1. Iraq was badly beaten last Gulf war and at the time, they just took it without doing anything. (I recalled that if it was not for Powell calling back the troops, many more Iraq troops would have been slau...

<t>Thanks KO, you're ok! err..one more question...if this were the case, that they are correlated, what would happen in the face of bankruptcy when a company's rating is being downgraded rapidly?
