Time to Sell that Apple Stock?

I'm still kicking myself for not buying up all the Apple stock I could immediately after my wedding, and I know everything in the financial district has been turning up roses for Apple as of late, but
O'Grady's PowerPage is playing economic trend prognosticator and has come up with some possibly sobering information about recent stock sells by Apple's upper-execs.  Are these sales indicative of upcoming financial problems with Apple? Or (my theory) did everybody just decide to go buy themselves yachts with Apple logos spray-painted on the side alongside monikers like
"Killer 1337 Mac", so that they can have crazy executive water-races where they shove handfuls of cash in their ears and cackle into the wind?!
