Talk:Fundamental theorem of asset pricing

I have been a bit quick writing this up. The following needs to be added:

1. Definition of the market including probability space, filtration, stochastic process used as a model for stock prices
2. better explanation of the duality between risk neutral measures and arbitrage
3. More stuff on the various different types of the fundamental theorem
4. equivalent martingale measure as synonym of risk neutral measure —Preceding unsigned comment added by AJR 1978 (talk • contribs) 19:32, 6 March 2006

What's written now seems to suggest that NFLVR is weaker than no-arbitrage. Surely it is stronger, i.e. NFLVR implies that there are no arbitrage opportunities but the converse is not true. —Preceding unsigned comment added by 78.82.85.33 (talk) 00:56, 15 January 2010 (UTC)

Intro

Check out what I've done. I think its context is sufficient now: Please check and consider removing the tag. RobertHannah89 (talk) 11:55, 29 September 2011 (UTC)

Bond

Shouldn't it be a money market account since its value is (unlike bonds) not subject to changes in the marekt interest rate? see also steven shreve's "stochastic calculus for finance" — Preceding unsigned comment added by 131.220.192.21 (talk) 15:07, 5 February 2012 (UTC)

Proof ?

IANAM, but I am concerned about the proof. The correspondent page in French mentions this as an hypothesis. --Japarthur (talk) 07:57, 9 March 2017 (UTC)
