I entered a 3 week double calendar using the $56 and $56.5 calls (long August monthly, short July wk5) at $0.75 and $0.73, respectively.
Earnings are 7/29 AC
Previously, we paid:
$0.80–$0.85 per spread for a 2 week calendar in October 2014 (exited for 27% gain)
$1.15–$1.20 per spread for a 4 week calendar in February 2015 (broke even)
In each instance, stock price was nearly identical to what it is at present.
