What is ‘Omega’

In finance, omega represents the percentage change in an option’s value with respect to the percentage change in the underlying price. Omega (Ω) measures the leverage of an options position.

Explaining ‘Omega’

For example, if Ford Motor Co (F) shares increase 7% in a given period and a Ford call option increases 3% in that same period, the omega of the call option is 3 ÷ 7, or 0.43. This would imply that for every 1% Ford stock moves, the call option will move 0.43%.

Options Greeks

Omega is one of the Greeks, a set of metrics that give a sense of an options contract’s risk and reward with respect to different variables. While there are many Greeks, omega is one of a limited number of first-order Greeks, meaning that it relates directly to the value of an options contract, rather than to another Greek. The most common first-order Greeks are:
