13 yr market cycle -- Search of the Day

someone from California just found my 666 post via this search:

at the time of this writing the top result on the search was this:

just think if the googler had clicked the "I'm Feeling Lucky" button. . .

in any case, if you are reading this post in search of info on 13 year cycles in the Stock Market, here is the definitive word on the subject:

666 - S&P 500 and the 13 Year Cycle


I also noticed that today is the 13th day of the 6th month of the year of the 9th year of the decade (or century even). bored as I am here on a Friday night/Saturday morning, since here in Quito it is "Ley seca", dry weekend because there is some obscure election on Sunday, effectively shutting down all the night life, I thought to search for 6 9 13 at The On-Line Encyclopedia of Integer Sequences to see if anything cool came up. first result was for this sequence:

1, 1, 1, 2, 3, 4, 6, 9, 13, 19, 28, 41, 60, 88, 129, 189, 277, 406, 595, 872, 1278, 1873, 2745, 4023, 5896, 8641, 12664, 18560, 27201, 39865, 58425, 85626, 125491, 183916, 269542, 395033, 578949, 848491

then I realized that I had seen this one before. the formula is a(n) = a(n-1) + a(n-3), so 4 + 9 = 13 and then 13 + 6 = 19 and so on. like a cross between the Fibonacci Sequence (a(n) = a(n-1) + a(n-2)) and the Padovan Sequence (a(n) = a(n-2) + a(n-3)).

the limiting ratio for this sequence is 1.46557....

that's pretty much right in the middle of the Plastic Number (1.32471) and the Golden Number (1.618). and since, as far as I can tell, this sequence and its limiting ratio are unnamed, I propose that we just call them the Middle Sequence and the Middle Number.

I have no idea yet if this has any numerological significance for markets analysis, but I'll let you Know if I turn up anything.
