While the risk curves for a calendar spread may look enticing at the time the trade is being considered, a trader needs to carefully assess the present level of implied volatility for the options on the underlying security to determine whether the present level is high or low historically. In this scenario, the long calendar trader would actually be expected to lose money from the volatility increase: (-$2.74 Short Option Vega x 2 Point IV Increase) + ($3.96 Long Option Vega x 1 Point IV Increase) = -$5.48 + $3.96 = -$1.52. During periods of high volatility, option prices are going to expand and time decay will be less on the back month contracts that you are long. Since a long calendar spread trader is short the near-term option and owns the longer-term option, the changes in implied volatility only account for $0.10 of the profits on the spread ($6.37 loss on the short option + $6.47 profit on the long option = +$0.10 profit). Figure 2: Risk curves for a calendar spread if implied volatility is 10% higher. When entering into a calendar spread, it is important to consider the current and future anticipated level of implied volatility.

With a vega of +2.95, a 1.3% decrease in the March 1,860 call's implied volatility should result in a $3.84 decrease in the long call's price (+2.95 x -1.3 = -$3.84). If volatility levels rise after the trade is entered, these risk curves will shift to higher ground—and the breakeven points will widen—as a result of the fact that the purchased option will increase in price more than the option that was sold.
