Theta decay rate

WebThe rate of time decay is measured by one of the options Greeks, Theta. The Theta value of an options contract theoretically defines the rate at which its price will decline on a daily basis. For example, the price of a contract with a Theta value of -0.03 would be expected to fall by approximately $0.03 each day. The term "theta" refers to the rate of decline in the value of an option due to the passage of time. It can also be referred to as the time decay of an option.
