exception to the rule and must have these 2 characteristics:

o 2) The CF’s o the assets are cotiget o the occurrece of specific eets
USING DCF would understate their value.
Basics of Option Pricing
Options gives you the right, not the obligation, to buy or sell underlying asset at a
predetermined (strike) price
o two positions in options: long (buyer) or short (seller)

financial markets:
o 1) Current value of the underlying asset:
o underlying increases call increases, put decreases
o 2) Volatility of the underlying asset:
o volatility increases call and put increase
o 3)Dividends paid on the underlying asset:
o dividends increase underlying decreases call decreases, put increases
o 4) Strike price of the option:
o strike increases call decreases, put increases
o 5) Time to expiration on the option:
o time decreases call and put decrease
o 6) Riskless interest rate corresponding to life of the option:
o interest increases PV (strike) is cheaper call increase and put decrease
