Few things to take note:
1. Christmas rally can end prematurely before 31 Dec
2. Christmas rally can start as early as Aug/Sept or as late as Nov
3. I only take the lowest to highest point between the highlighted duration
Some statistics from 2009:
2009: 2 Nov - 29 Dec up 9.84%
2010: 31 Aug - 5 Nov up 17.8%
2011: 4 Oct - 27 Oct up 20.08%
2012: 15 Nov - 18 Dec up 7.25%
2013: 10 Oct - 31 Dec up 12.27
To have the most similar inception of rally, i would compare to last year's rally where it started 6 days earlier.
In 2013, it took 55 bars to achieve 12.27% increment in SPX index.
At the moment, we only need 16 bars to achieve 12.26%.
There is only one thing in my mind.
a) This bull is really raging which could see the index going to 2182 considering a 20% increment
b) This so-called rally will just end up ranging and SPX finishes year 2014
c) somehow if MEGAPHONE resistance in play, SPX will plunge in yet another two weeks below 1820 (which will still make 2014 a yearly
This "crazy" mentality sound so humanly possible especially the big are looking at how to manipulate the technical chart :-)
Merry Christmas in advance
