Options have value for two reasons

» Cost of money- Interest rates less dividends» Volatility- How much the asset varies during the

length of the options contract

5

Black-Scholes option model

» Parameters of Black-Scholes model are:» Stock price» Strike price» Time remaining until expiration» Risk-free interest rates and dividends» Volatility as measured by standard deviation

6

Volatility defined

» Volatility is the amount of movement an underlying can exhibit, either up or down

» The official mathematical value of volatility is defined as the annualized deviation of stocks daily price changes

7

Types of Volatility

» Historical Volatility- Measure of actual underlying price changes over a specific period of time

» Implied Volatility- measure of how much the market expects the underlying asset to move, for an option price. This is backward engineered from the Black-Scholes model, solving for volatility instead of theoretical option price

8

Volatility levels

» Volatility generally increases during periods of falling stock prices

» Volatility generally decreases during periods of rising stock prices

» There are exceptions though, if a stock rises quickly, volatility may actually rise

9

Options require a forecast

» What if you were to be uncertain on direction but were predicting a large move up or down in an underlying asset?

» A couple of strategies might benefit from dramatic movements in the market

10

Straddle

» Example- One forecast: XYZ could be much higher or much lower in the future??

11

Example

» Stock is $22.19» Buy the 47 day 22.5 call for $1.70 and buy 47 day

22.5 put for $1.80, total debit $3.5 » Implied volatility is 57%, this is the backward

engineered from the trading price that is derived from the option exchanges

12

Risk/Reward graph

13

Sell straddle to close position prior to expiry

» Profitability depends on how far the stock moves and implied volatility

14

Straddle position at expiration

15

Breakeven at expiration

» Straddle buyer purchases two rights, right to buy stock at $22.5 and the right to sell stock at $22.5

» Upside breakeven point $22.5 + $3.5= $26.0» Downside breakeven point $22.5 - $3.5= $19

16

Risk and Reward is balanced

» If an investor is predicting a dramatic move up or down this strategy may be suitable

» Risk and reward are inextricably linked

18

Strangle

» Another alternative strategy: Buy 47 day 25 strike call for .75 and buy 47 day 17.5 strike put for .50

» Investor has the right to sell stock at 17.5 and the right to buy stock at 25 until expiration

» Strangle volatility purchased was an implied volatility of 58%

Risk/reward graphs

20

Sell prior to expiry

» Profitability depends how far stock moves and the implied volatility at the time of sale of the strangle

21

Risk/reward at expiry

22

Strangle breakeven at expiration

» Downside breakeven is $17.5-$1.25= $16.25» Upside breakeven is $25+ $1.25= $26.25

23

Volatility is the key to option pricing

» One concern: Implied volatility, the market forecast for future volatility is much higher than the historical volatility

» Economics may be too difficult? What if the volatility reverts back to 40%

24

Why does the situation occur?

» Market may be expecting news that will dramatically impact the underlying price of the stock, either positively or negatively

» Examples of this may include FDA rulings, product litigation cases and earnings announcements

25

Example

» Stock is $22.19» Buy the 47 day 25 call for $.75 and buy 47 day

17.5 put for $.50, total debit is $1.25

26

Risk/reward prior to expiry

27

Sell strangle to close prior to expiry

» Profitability depends on how far the underlying moves and the implied volatility when you exit the option

» The implied volatility purchased was approximately 58%

28

Strangle position at expiration

29

Breakeven at expiration

» Strangle buyer purchases two rights, right to buy stock at $25 and the right to sell stock at $17.5

» Upside breakeven point is $25 + $1.25= 26.25» Downside breakeven point is $17.5 - $1.25= 16.25

Comparing Straddles and Strangles

» Straddles- higher cost, lower leverage, and the breakeven points are closer together

» Strangles- Lower cost, higher leverage, and the breakevens are further apart

34

Risk and Reward is balanced

» If an investor is predicting a dramatic move up or down this strategy may be suitable

» The maximum loss for either straddle or strangle purchase is the debit paid

» Risk and reward must always be balanced» Selecting either a straddle or strangle to benefit

from price movement will be determined by weighing the cost of each strategy and the breakeven points

35

Summary

» Investor must be predicting a large move in an underlying to enter into a long straddle or strangle

» Volatility can be a major factor for profitability of strangles and straddles, caution must be used as future volatility is difficult to forecast
