You got it right - the mother of all indices! US Banking Index. It never happens that world markets will top out without the US Banking index - where all the mess started off back in July 2007.
US Bank Index has underperformed S&P500 for the last few months and it has just started rallying - trying to take out resistance around 51. To me the writing is on the wall - If KBW Bank Index does manage to take out the resistance level then don't look for a top in S&P500 or any other world markets very soon!
The next one is Topix Japanese Banking Index, which is down 90% from its 1992 levels! It recently hit an all time low in November!

One more picture -- the Japanese Index from 1984-2010
BTW -- As of this morning (22nd Dec) in US markets, US Bank index has made a 6 month high crossing the 51.XX resistance. It looks like it can go up another 7-8% before it meets next resistance at 56-57 range.
