If the interest rate R were not zero, we would need to discount the expected value appropriately to get the price. is a random variable on the probability space describing the market. The concept of a unique risk-neutral measure is most useful when one imagines making prices across a number of derivatives that, This page was last edited on 16 March 2023, at 12:25. In the future we will need to return the short-sold asset but we can fund that exactly by selling our bought asset, leaving us with our initial profit. t , then by Ito's lemma we get the SDE: Q /Length 348 /Contents 42 0 R For simplicity, we will consider the interest rate to be 0, so that the present value of $1 is $1. Q-measure is used in the pricing of financial derivatives under the assumption that the market is free of arbitrage.

For example, the central value in the risk-neutral probability weighting is based on the price increasing at T ( /Font << /F19 36 0 R /F16 26 0 R >> r I think the author gives the best explanation I've seen https://books.google.ca/books?id=6ITOBQAAQBAJ&pg=PA229&lpg=PA229&dq=risk+neutral+credit+spread+vs+actuarial&source=bl&ots=j9o76dQD5e&sig=oN7uV33AsQ3Nf3JahmsFoj6kSe0&hl=en&sa=X&ved=0CCMQ6AEwAWoVChMIqKb7zpqEyAIVxHA-Ch2Geg-B#v=onepage&q=risk%20neutral%20credit%20spread%20vs%20actuarial&f=true.
