OPTIONS
It Works!
The Magic Of Time Valueby Jesse Chen
TOO often in the world of option analysis, simple indicators are overlooked for more advanced mathematical models. Traders always try to stay delta-neutral or rack in maximum theta. Option gurus tout exotic option spreads, which monitor positive gamma vega and theta convergences.These Black Scholes-based greek and volatility formulas can be very powerful tools if used correctly. Otherwise, the trader could end up being overwhelmed by the number crunching and facing the next trade decision, frozen like a deer in headlights.
TIME VALUE
A very simple indicator you can use is time value, which shows what you are paying for the option in addition to its exercise value. Generally, the more time an option has until expiration, the higher the time value. Volatility also increases time value.
Time value is the excess value in an option price above the intrinsic value:
For example, a 95 call option sells for $7. The underlying stock is $100.Intrinsic value (calls) = Current underlying price - Strike priceIntrinsic value (puts) = Strike price - Current underlying price<Negative intrinsic value is zero>Time value = Option price - Intrinsic value
...Continued in the June issue of Technical Analysis of STOCKS & COMMODITIESIntrinsic value = 100 (underlying price) - 95 (strike) = 5Time value = 7 (option price) - 5 (intrinsic) = 2
