3 Opions Derivaives A financial insrumen ha gives you he righ o buy or sell a share a a specified price Call opion - he righ o buy a a specific price (he exercise price u opion - he righ o sell a a specific price (he exercise price Real Opions and Dynamic ricing 3
4 Basic Types of Opions European call - gives he owner he righ o buy on a specific dae pu - gives he owner he righ o sell on a specific dae American gives he righ o buy or sell a any ime prior o a specific dae Real Opions and Dynamic ricing 4
5 Oher Terminology A long posiion - you acually own he securiy e.g. he way mos of us inves in socks or muual funds A shor posiion - you have sold a securiy ha you don own Noe: if you sell or wrie an opion conrac, you have a shor posiion on ha conrac Real Opions and Dynamic ricing 5
6 Why Buy Opions 1. Cheaper han underlying securiies - can ge a huge posiion on a securiy for a low price 2. Risk managemen - opion pays if sock rises or falls by a large amoun - can proec your porfolio from a very volaile marke 3. Regulaory reasons (e.g. some places don allow shor selling Real Opions and Dynamic ricing 6
7 Value of a European Call Gives you he righ o buy a sock for $K a some fuure dae, T When would you use i? If he sock price, S T, is bigger han K, hen you exercise your opion and buy a share for $K, hen immediaely sell i for $S T, and make a profi of S T -K If he fuure price is less han $K, you do nohing Thus, he value a ime T is max(s T -K,0 Real Opions and Dynamic ricing 7
8 Value of a European u Gives you he righ o sell a sock for $K a some fuure dae, T When would you use i? If he sock price, S T, is smaller han K, hen you buy a share on he marke for $S T, hen exercise your opion and sell i for $K, and make a profi of K-S T If he fuure price is more han $K, you do nohing Thus, he value a ime T is max(k-s T,0 Real Opions and Dynamic ricing 8

11 Mehods for ricing Real Opions and Dynamic ricing 11
12 Valuing Opions by Arbirage Mehods If an invesmen has no risk, i should yield he risk-free rae of reurn (T-Bills, if no we can creae wealh money making machine Real Opions and Dynamic ricing 12
13 Example Sock rades a $40 European call has exercise price of $40 Risk free rae is 1/9% (per period A very simplified world... In one period, one of wo hings will happen: sock rades a $32 sock rades a $50 Form a orfolio x shares of sock, sell 1 call Real Opions and Dynamic ricing 13
14 Arbirage ricing Sock rice orfolio 50x-10 32x-0 W/ no risk, porfolio mus be equal under boh sock price scenarios 50x-10=32x 18x=10 or x=5/9 A porfolio of 5/9 shares, shor a call no risk, gen. Risk free reurn Value in 1 period * 1/(1+r = iniial value 5/9*40 c =1/(1+1/9*32*5/9 c=56/9 Real Opions and Dynamic ricing 14
15 2 nd Example Sock rades a $20 European call has exercise price of $21 Risk free rae is 12% A very simplified world... In 3 monhs, one of wo hings will happen: sock rades a $18 sock rades a $22 Form a orfolio 0.25 shares of sock, sell 1 call Real Opions and Dynamic ricing 15
16 Example This consrucion gives us a risk-free porfolio whose value is he same no maer wha happens in he fuure! Good Value of socks = = $5.50 Value of opions = -1 (22-21 = -$1.00 Value of porfolio = $5.50-$1.00 = $4.50 Bad Value of socks = = $4.50 Value of opions = -1 (0 = 0 Value of porfolio = $4.50 Real Opions and Dynamic ricing 16
17 Risk Neural ricing If his porfolio is no subjec o risk, hen invesors mus be indifferen beween his porfolio and a risk free bond wih he same payoff ($4.50 in 3 monhs Why? If hey weren, you could buy one and sell he oher o creae a risk free money pump Real Opions and Dynamic ricing 17
18 Value of porfolio in hree monhs = $4.50 Value of porfolio now = 4.50 e = $ = (price of call oday price of call oday = =.63 And if i wasn $0.63, we would have an arbirage opporuniy. Real Opions and Dynamic ricing 18
19 In a risk-neural world, invesors do no demand any premium o ake on exra risk (In he real world, risky invesmens have a higher average growh rae han safe ones - a risk-reurn radeoff. Thus, in a risk-neural world, all asses grow a he risk free rae. Why? If asse A grew faser han asse B, all invesors would prefer A since hey are neural o risk. We use his observaion o deermine he probabiliy ha he sock price rises or falls in a risk-neural world. Real Opions and Dynamic ricing 19
20 Since invesors are risk neural, he sock grows on average a he risk-free rae. rice in 3 monhs = 20 e = $20.61 Then he expeced sock price afer 3 monhs mus equal $ Le p = probabiliy ha he sock goes up in a risk-neural world. Good $22 $20 Bad p 1-p $18 EV sock price = p 22 + (1-p 18 = 18+4p Thus, = 18+4p p=.65 Real Opions and Dynamic ricing 20
21 Deermining he Opion s Value Good $22; opion value = $1 $20.65 Bad.35 $18; opion value = $0 A 3 monhs: EV opion = =.65 EV now =.65 e = $0.63 Real Opions and Dynamic ricing 21
22 Basic Approaches o ricing For vanilla European opions (pus and calls, a formula exiss For exoic European opions, can simulae For American-syle opions, need o use a decision ree approach Real Opions and Dynamic ricing 22
