Scott McNealy blamed SUN's misfortune on moving to a former psychiatric ward in Santa Clara - it coincides with SUN's loss of luck (and some directors really believed the building was cursed). Also, business-wide there is a known "headquarters curse", when a company feels it needs to have a more representative HQ. Let's see what it does to Apple.

I think the failure has more to do with leaders who believe in curses than actual curses.
