# Calculating Greeks in Covered Calls?

Just want to confirm whether Delta, Gamma, Theta, Vega will be calculated in the following way? Since we own 100 shares of stock while selling a call we need to subtract greek value from one? right?

Covered Call Delta = 1 - "Long Call delta"

Covered Call Gamma = 1 - "Long Call gamma"

Covered Call Theta = 1 - "Long Call theta"

Covered Call Vega = 1 - "Long Call vega"

You are right for delta but wrong for other greeks.

Delta of stock is 1 so Covered call Delta = 1 - "long call delta" is correct

However a stock doesn't have gamma , theta or vega. So these greeks of your covered call positions will be just that of short call. i.e

Covered Call Gamma =  - "Long Call gamma"

Covered Call Theta =  - "Long Call theta"

Covered Call Vega =  - "Long Call vega"
