Theta - Definition
Theta is the
options greek
that measures the rate at which a stock option's value diminishes over time with the underlying stock remaining
stagnant.
Theta Explained
Time decay, the diminishing of the price of
stock options
with the underlying stock staying still, is truly the main enemy of every buyer of
stock options. Theta estimates that daily decline of value, allowing options traders to estimate the risk of holding each options contract.
Theta is highest for
At The Money (ATM) Options and lowest for deep
In The Money
or far
Out Of The Money options. That is why options traders
not wanting to risk a decline in value due to an extended wait for the stock to perform rather go for the safe In The Money options.
