I'm thinking about somthing new. Spend $5,000 every month buying SPY 150 Leap calls that expire 2014. When SPY will be high, $5000 would buy less calls. When SPY will be low a lot more calls will be purchased reducing my average dramatically. At any point once the value of the calls is more then 50% of my average, I sell everything & start over again. In 9-12 months I would start using the 2015 calls instead of the 2014 (roll over) to minmize time decay effect. Is this a good long term strategy?
