Option Greeks measure the sensitivity of GOOG option prices to various factors. Delta measures price sensitivity to a $1 move in GOOG. Gamma measures the rate of change of delta — highest for ATM options near expiry. Theta measures daily time decay — the amount an option loses in value each day. Vega measures sensitivity to a 1% change in implied volatility. Rho measures sensitivity to interest rate changes. StrikeVue displays all Greeks for every strike across 5 expiries for GOOG on NYSE/NASDAQ.

At-the-money (ATM) options for GOOG typically have a delta of approximately 0.50 for calls and −0.50 for puts, meaning they move roughly $0.50 for every $1 move in GOOG. Deep ITM options approach a delta of 1.0 (calls) or −1.0 (puts), while far OTM options approach 0. The current ATM implied volatility for GOOG is 3239.0%, which affects the Greeks of all strikes.

GOOG's IV Rank is currently 0 out of 100. High IV Rank inflates vega — options are more sensitive to volatility changes and carry higher premium. It also affects theta, as higher-premium options decay faster in absolute terms. With low IV Rank, buying premium (long vega strategies like Straddles) offers cheap exposure to a volatility expansion for GOOG.
