Ito's Lemma Derivation of Black-Scholes Solving Black-Scholes E cient Market Hypothesis Past history is fully re ected in the present price, however this does not hold any further information. (Past performance is not indicative of future returns) Markets respond immediately to any new information about an asset.

Then I defined integration using differentiation-- integration was an inverse operation of the differentiation. But this integration also had an alternative description in terms of Riemannian sums, where you're taking just the leftmost point as the reference point for each interval. 2014-01-01 Note that while Ito's lemma was proved by Kiyoshi Ito (also spelled Itô), Ito's theorem is due to Noboru Itô.

The Vasicek model is While this lemma is quite easy to use, the proof usually relies heavily on technical lemmas, hence difficult to develop intuition, especially for the first time reader. With this motivation in mind, it was quite pleasant to discover a set of excellent lecture notes by Jason Miller (2016), which contained an alternative proof built on the idea of Stone-Weierstrass Theorem . Now, we can calculate the price of the option if we assume that the stock can be modeled using Ito’s lemma, which brings us back to the equation above: Using the above equation and the fact that the price of the option = cost of hedging with stock and cash, we can derive our Black-Scholes equation.

One additional source the reader may appreciate is the book by Kushner and Dupuis (2001), which provides several examples of Itô's Lemma with jump processes.

When I first started working as a quant I managed to find an alternative form for the rules which sits well in a Black-Scholes type of world and corresponds more closely to a trader’s way of describing a trade.

First, I defined Ito's lemma--that means differentiation in Ito calculus. Then I defined integration using differentiation-- integration was an inverse operation of the differentiation. But this integration also had an alternative description in terms of Riemannian sums, where you're taking just the leftmost point as the reference point for each interval.
