Re: End of bitcoin?

ICO is something to be in the hands of government, that is a public container of wealth not belong to any specific individual.

Re: If you are bored with Deep Networks

Completely disagree with it. katastrofa: Quantum annealers (e.g. D-wave) find global minima. What deep networks may do, unlike classical algorithms, is finding correlations of the minima positions (more complex than e.g. momentum methods) - it's a quantum algorithm's capability. Introducing memory ...

Numeraire's vol = market price of risk ??

<t>Hull book says, to make phai = f / g to be martingale, g's vol should be equal to market price of risk lambda. Where f = one process g = numeraire process phai = f / g lambda = ( u - r ) / volaHowever, Shreve's book does not use this condition but depends on Radon-Nikodym and Girzanov's theorem. ...

What are the stupidest things people have said about risk neutrality?

<t>Thanks list for reply again. I just bought 7th edition of Hull but it still has same line as before, i.e. 'expected return on all securities is the risk free intereat rate in risk-neutral-world'. If this line is not correct, somebody should tell him to correct this. In any case I think I need to ...

What are the stupidest things people have said about risk neutrality?

<t>Thanks list for quick comment. So far I am following Hulls book. Hull's book says that 'expected return on all securities is the risk free intereat rate in risk-neutral-world'. This will coincide to my experience that to verify BS by MCSimuilation, I have to use risk free rate as expected return....

What are the stupidest things people have said about risk neutrality?

<t>Thanks list for your kind attention and remarks. Apologies for my errors. My math is poor. I think this issue is very much philosophical rather than mathimatical/financial. Logic can be build on t=0 discrete relationship/models. But in time-space we are living in now, there is huge GAP in between...

Risk Neutral pricing...

<t>I got same question. In addition to your list, I will add CAPM where expected return is risk free only when vola is zero. RN says all asset's expected return is risk free. Future=Spot*exp(rf) applies always irrespective of choice of theory. This is because otherwise arbitrage will eventually flat...

<r>Happy new year Fermion, I went through FAQs but still have one question. I apprecaite if you can help me. I started my career as engineer so I still believe that all pricing should be properly duplicated by monte carlo simulation. How BS result can be verified by MonteCarlo simulation ? I think t...
