Options Vega is the change in the value of an option for a 1-percentage point increase in implied volatility.
Vega of a long option position (both calls and puts) is always positive. At-the-money options have the greatest vega
An option goes in-the-money or out-of-the-money, the smaller is vega. As time passes, option vega decreases
Time amplifies the effect of volatility changes. As a result, vega is greater for long-dated options than for short dated options
As the above graph indicates, As volatility falls, vega decreases for in-the-money and out-of-the-money options; vega is unchanged for at-the-money options
