Vega represents the change in the price of an option when the underlying implied volatility changes by 1%.
We see that strikes closer to at the money have a higherthan in and out of the money. This means trades like Straddles are more sensitive to moves in volatility than wider .
Additionally, when the trade is at 45 days to expiration, we exhibit a much larger Vega value than when the trade is 5 days to. This places more importance on positions early, since closer to expiration, we will no longer benefit from an decline since Vega is low.
