1. SMB CAPITAL OPTIONS TRAINING PROGRAM

2. SESSION FOUR THE GREEKS

3. Options Greeks • Options prices are always based on market supply and demand. • However predictive models have been developed to measure effect on changes in price, time and volatility. • These measurement are known as “the greeks”.

4. Options greeks predict changes in prices of options • Delta--Effect of movement of underlying stock or index on an option’s price. • Gamma—Rate of change of delta. • Vega—Effect of fear of future price volatility on an option’s price. • Theta—Effect of passage of time on an option’s price. • Rho—Effect of interest rates on an option’s price.

5. DELTA • Delta=statistical chance that option will expire in the money. • Delta also equals the predicted price change of the option based on a 1 point change in the underlying. • Long calls and short puts and actual shares of stock have positive deltas. • Short calls, long puts and short stock have negative deltas.

6. OUT OF THE MONEY DELTAS

7. IN THE MONEY DELTAS

8. PROPERTIES OF DELTAS • ATM CALLS OR PUTS HAVE ABOUT 50 DELTAS—50% CHANCE OF EXPIRING IN THE MONEY. • THE SUM OF A CALL AND A PUT AT THE SAME STRIKE SHOULD BE APPROXIMATELY 100%--PROBABILITIES OF EXPIRING ITM. • BACK MONTH OPTIONS HAVE HIGHER DELTAS THAN THE SAME STRIKE FRONT MONTH OPTION—GREATER CHANCE OF EXPIRING IN THE MONEY AS OPTION IS AT RISK LONGER. • AS OPTIONS GO FARTHER OTM THE DELTA DROPS. • AS OPTIONS GO DEEPER ITM THE DELTA INCREASES. • DISTANCE BETWEEN DELTAS WIDENS CLOSER TO EXPIRATION.

9. GAMMA • The second derivative of price. It’s the “delta of the delta”—the rate of change of delta. • Each 1 point move in underlying changes delta by amount of gamma. • You ADD gamma to delta if the underlying moves up to arrive at the new delta. • You SUBTRACT gamma from delta if the underlying moves down 1 point. • So call deltas get more positive in rallies and put deltas get more negative in sell-offs.

10. Out of the money Gamma

11. In the money Gamma

12. PROPERTIES OF GAMMA • Gamma is highest for ATM options or nearest options to ATM • Gamma gets very high as expiration nears so deltas can change very quickly which is dangerous if you are short options (chances of expiring ITM changes dramatically near expiration as price moves because of gamma) • Front month gamma is higher than back month nearer to the money-reverse for far OTM.

13. Theta • Measures daily deterioration of extrinsic value in long options. • Theta of an option is the predicted deterioration of its time premium (extrinsic value) in one trading day. • This is the key to income trading—we are net sellers of options-- taking advantage of their deterioration in value over time. • Any long option automatically reduces theta of an options position. • Selling a long option automatically increases theta of the position.

15. In the money theta

16. Properties of theta • At the money options burn off theta fastest. So short ATM options have the opportunity for the quickest appreciation. • Back month ATM options have much less theta than front month ATM options. • Back month OTM options have more theta than front month OTM options at the same strike. • ATM options theta increases rapidly as expiration approaches. • Farther out options theta decelerates towards expiration.

17. Vega • Measures how an option reacts to changes in market price volatility. • An option changes by the vega amount given a one point move in “implied volatility (IV)”. • Implied volatility is the one standard deviation range of prices (68.3%) for the stock or index over the next 365 days.

18. Out of the money vega

19. In the money vega

20. Properties of vega • ATM options have the most vega and • Back month options have more vega than front month options primarily because there is more time premium impacted by the increase in volatility. • As options approach expiration, vega decreases as less time premium is present. • Vega goes to zero at on expiration day.

21. Rho • Measures effect of changes in interest rates on • A 1% change in interest rates will cause an option to change value by the value of its rho. • This has the greatest effect on leap options (long term options).

22. Why are the greeks important? • The essence of income options trading is to take advantage of theta decay by being short options. • All of the other greeks create risk while theta creates the reward. • The game is to control the risk of the “risk” greeks so as to maximize the reward of the “reward” greek which is theta. • Our next session will expand on this quite a bit.

23. Homework • Go into Optionvue and pull up the Options Chainfor fifteen stocks of your choice of the S and P 500 priced greater than $75. (google “components SPX index”). • Select 5 of those stocks and go back in time through backtraderuntil you get to 30 days before any month’s expiration. Pull up the options chain for that expiration. For each stock sell a 10 lot at-the-money call 30 days out. Mark down the delta, gamma, vega and theta every three days until expiration of those options. Note how they change as time passes and market price and volatility changes. • Select 5 different stocks and pull up the options chain from a recent expiration 60 days prior to that expiration. Buy a 10 lot put spread with a delta at around 10 or a bit lower ( a far OTM put). Mark down the delta, gamma, vega and theta every six days until expiration. Note how they change as time passes and market price changes. • Select the remaining 5 stocks and pull up the options chain for 45 days out from a recent expiration. For each stock buy a 10 lot call with a delta of 90 or greater (deep in the money call). Note how they change as time passes and market price changes.
