One of the points I recently chatted to a client about was the general propensity for calendar pairs to be somewhat delta directional with the underlying flat price prompt month future.
At times, the same can be true for other spread combinations ( like a butterfly for example ) as well - but on a much less frequent basis, and for shorter periods of time.
