Delta at outset: .50 = option will go up/down .50 for each 1.00 move in the underlying asset

Gamma: If strike is at-the-money, the will have its maximum gamma. Gamma will increase as expiration day approaches if option is at-the-money at that time. Typically, gamma will increase at a great rate when options has less than 20 days to expiration.

Theta: If option will be held to expiration, theta will rise coming into expiration day if option is at-the-money. Typically, theta will increase at a great rate when option has less than 20 days to expiration. When you are long the option, theta is your enemy. Passage of time where the underlying asset does not move is dead money.

Gamma, Theta & Vega are all greatest when the option is at-the-money. As options go depp in-the-money or way out-of-the-money, all three greeks will decrease and the delta will be the primary driver of price changes.
