FINANCIAL INSTRUMENT MODELING IT FOR FINANCIAL SERVICES (IS356) The content of these slides is heavily based on a Coursera course taught by Profs. Haugh and Iyengar from the Center for Financial Engineering at the Columbia Business School, NYC. I attended the course in Spring 2013 and again in Fall 2013 and Spring 2014 when the course was offered in 2 parts.

Stock Price Dynamics – binomial lattice 9 Stock price goes up/down by the same amount each time period. In this example: 1.07 and 1/1.07
10
Options Pricing – call option formula 10 The value of the option at expiration is Max(S T - K,0). You will only exercise a European option if it is in-the-money at expiration, in which case the price of the stock (S T ) at expiration is greater than the strike price K. We will move backwards in the lattice to compute the value of the option at time 0.
11
European Call Option Pricing Example 11 15.48 = 1/R( 22.5q + 7(1-q)) R=1.01 Q=(R-d)/(u-d) d=1/1.07 u=1.07 A European put option uses the same formula. The only difference is in the last column: max(0, K-S T ). You only exercise a put option if the strike price > current price. You can buy shares at the current price and sell them at the higher strike K.

Yield Curves (US Treasuries) 29 Source: http://www.treasury.gov/resource-center/data-chart-center/interest-rates/pages/TextView.aspx?data=yieldYear&year=2013 Rates are climbing – highest in Dec 2013
30
Sample Short Rate Lattice 30 9.375% = 7.5% x 1.25
31
Pricing a Zero-coupon Bond (ZCB) 31 9.375% comes from the last slide Assumes a 50:50 chance of rates increasing/decreasing
32
Excel Modeling 32 Again, we work backwards through the lattice. 89.51 = 1/1.1172 * ( 100 x 0.5 + 100 x 0.5)
33
Pricing European Call Option on ZCB 33 Max(0, 83.08-84) Max(0, 87.35-84) Max(0, 90.64-84)
