Explain the Concept of ‘Delta’ for an Options Contract.
Delta is one of the "Greeks" and measures the sensitivity of an option's price to a $1 change in the price of the underlying asset. It is expressed as a value between 0 and 1 for calls, and -1 and 0 for puts.
A Delta of 0.50 means the option price is expected to move $0.50 for every $1 move in the underlying asset.
