Gamma is one of the most critical factors in options trading. It measures the rate of change in an option’s price concerning changes in the underlying asset’s price. The higher the gamma, the more volatile the option. Gamma is essential when trading near-term options.
Theta is another critical factor in options trading. It measures the rate of change in an option’s price concerning time decay. The higher the theta, the more sensitive the option is to time decay. Theta is especially important when trading long-term options.
Higher gamma and higher theta options are more expensive than lower gamma and lower theta options. However, there are times when high gamma or high theta options can be a bargain. For example, when implied volatility is low, high gamma options may be underpriced.
Options strategies for high gamma or high theta situations
Some options are designed to take advantage of high gamma or high theta situations.
The straddle
For example, the straddle is a strategy that involves trading a call and a put option that has the same price and expiration date. The straddle benefits from large price movements in either direction.
The iron condor
Another example is the iron condor, which is a strategy that involves selling a call and a put with different strike prices but the same expiration date. The iron condor benefits from time decay as long as the underlying asset remains within a specific range.
When to use high gamma or high theta options
Traders can use high gamma or high theta options in various situations.
Buying Gold Coins: A Smart Investment ChoiceIf you are expecting a significant price movement
Consider using high gamma options if you expect a significant price movement in either direction. For example, if you expect a significant stock market move, you could buy an at-the-money straddle.
If time decay is working against you
If time decay is working against you and you are worried about your position losing value, then consider using high theta options. For example, if you are holding an iron condor close to expiration and the underlying asset is approaching one of the short strikes, you could buy a longer-dated put to hedge your position.
