Are Options Greeks Helpful at All?
The Options Greeks are more than helpful, they are essential to evaluate and understand the behavior and potential future behavior of the option contract or spread.
We also see it as the most added parameters to the Brutus Options Ranker.
The most important Greek is likely Delta. It tells you how closely the option or option spread behaves like the underlying stock. It also provides a good estimate of what the probability is that the stock price will touch the strike price…. that’s a nifty little shortcut.
Here is a great way to remember the greeks and a short explanation of each:
- Delta is the Difference you would see in the options price with a $1 move in the underlying stock.
- Gamma is for the Gambling. I.e. if you are long gamma then you are gambling in hopes that the stock will move a lot and if you are short gamma you are gambling that the gamma doesn’t explode near expiration [sorry for this one - it doesn't match the pattern of the rest of the greeks ;)]
- Vega is for how the option responds to changes in Volatility.
- Theta is how the option changes in value as Time marches on.
There’s of course more to learn, just remember for now:
Delta is for Difference.
Gamma is for Gambling (speculation)
Vega is for Volatility, and
Theta is for Time Decay
Best of luck. May the Greeks be with you.
