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 higher vega than strikes in and out of the money. This means trades like straddles are more sensitive to moves in volatility than wider strangles.
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 expiration. This places more importance on managing positions early, since closer to expiration, we will no longer benefit from an IV decline since Vega is low.
