I note in Hirsch's Almanac that day after Easter is on average down in the US (nb 2005 is the latest I have). This really makes my fingers itch to keep the position over the weekend. How spread is the "knowledge" of a downbias? I think it just might turn upside down....and go up. Besides, if the holiday indicator would actually work this time, then we should see an up day in the US today (opening after our close) and this should countereffect a down monday.
