Cisco Covered Calls Rolled Out and Up

Cisco (csco ) reported earnings yesterday and is trading around $20.

CCI remains long the Jan 13 (Leaps) $10 calls.  We had sold the $20 Feb calls against that position, with the belief the stock would be challenged to break trough $20 and this covered call could boost returns.   This year's relatively rapid move to $20 has been surprising and overall positive for the leveraged LEAP position.  However, with the straight up move there was never really an opportunity to harvest any of the premium from the $20 Feb covered call.  Today we rolled the $20 Feb calls to the $21 Apr calls for a non-material $.03 debit /contract.  This gives us

•  either - more time to harvest this option premium if the stock pulls back
• or -  increases the potential gain from the spread by $1 if the stock rises.
