Is It Time to Wait For The Next Shoe To Drop Or Start Buying

I am going to continue with buy and hold of High Dividend and Safe Large Caps.    With Options I will "Trade the Market" for ups and downs during the summer.    I sold my APPL Call yesterday for a 30% gain and will wait for APPL to return to the 250 level to Buy in the money calls at that level.     Any other ideas on how to profit from a horizontal market I think will last for most of the summer?
