Option traders use delta to gauge how sensitive a particular option contract is to changes in the underlying security’s price. Delta can be positive, negative, or zero, depending on whether the option position profits from a rise (positive delta), falls (negative delta), or remains unchanged (zero delta) in the underlying security’s price.
Option's DELTA represents the change in price of an option with respect to change in price of an underlying. Let's understand briefly with the help of Nifty example. 1️⃣ In the above Nifty example, 17750 is an At the Money CE option. Delta of ATM CE is near 0.5 Which means that if spot moves 10 points, 17750 CE will move 5 points. Normally ATM options are highly volatile options. 2️⃣
To calculate position delta, multiply .75 x 100 (assuming each contract represents 100 shares) x 10 contracts. This gives you a result of 750. That means your call options are acting as a substitute for 750 shares of the underlying stock. So you can figure if the stock goes up $1, the position will increase roughly $750.VUpUL.
