| omega baryon n. A subatomic particle in the baryon family having a mass 3,272 times that of the electron, a unit negative electron charge, and an average lifetime of 8 × 10-11 seconds. Also called omega. See Table at subatomic particle. |

Omega
A measure of the change in an option's value with respect to the percentage change in the underlying price. The omega gives option investors an idea of how the option price and the stock price that underlies it move together.
Omega is the third derivative of the option price, and the derivative of gamma.
Investopedia Commentary
If the omega on a Ford call option is calculated to be 1.6%, then for every 1% change in the price of Ford the price of the call option will rise by 1.6%.
Also known as "speed".

| omega baryon
A subatomic particle in the baryon family, consisting of three strange quarks. It has a mass 3,272 times that of the electron, a negative electric charge, and an average lifetime of 8 × 10-11 seconds. The 1964 experimental observation of this particle was a great triumph in the history of particle physics, because its existence, mass, and method of decay had been predicted based on the model of baryons, but it had not yet been isolated. See Table at subatomic particle. |
| omega meson
A neutral meson having a mass 1,532 times that of the electron and an average lifetime of 6.6 × 10-23 seconds. See Table at subatomic particle. |
