Delta: \(\Delta\) measures the sensitivity of an option price change in relation to the changes in the underlying stock price. $$ \Delta = \frac{\partial V}{\partial S} $$ , where \(V\) is the option price, and \(S\) is the underlying stock price. Call Delta range: \([0, 1]\). Put Delta range: \([-1, 0]\). The closer Delta is to +1 or -1, the more strongly that the option's premium responds to the change in the stock price.
