In the option chains, what do the yellow and white sections indicate?
The yellow section indicates when an option contract is ‘In-the-money’ (ie: profitable to exercise the contract); the white section denotes when contracts are ‘Out-of-the-money’ (not profitable to exercise). A call option is in-the-money when the option’s exercise (strike) price is below the market price of the underlying security. A put option is in-the-money when the excercise (strike) price is above the market price of the underlying security.
