2011: A Prime Year, from Jim Sogi
Locusts tend to swarm in prime number intervals. It reduces the years in which there might be an overlap with other niche competitors.
Following this idea, here is a thought experiment. Any yearly cycle system must peak or trough on a multiple, making a prime a non-peak or trough in any given cycle system. That in turn means under a cycle following analysis that we are between either a peak or a trough. Since we had a trough recently, that would leave that we have not hit the peak.
Ki Zussman notes:
Speaking of prime numbers, here are the DJIA annual returns for years which were prime numbers (1930-present):
Date DOW prime
12/1/2003 0.253
12/1/1999 0.252
12/1/1997 0.226
12/1/1993 0.137
12/1/1987 0.023
12/3/1979 0.042
12/3/1973 -0.166
12/3/1951 0.144
12/1/1949 0.131
12/1/1933 0.637
12/1/1931 -0.527
One notes these years had higher mean returns than non-prime years, but the difference was insignificant:
Two-sample T for DOW prime vs DOW
N Mean StDev SE Mean
DOW prime 11 0.105 0.288 0.087 T=0.52
DOW 70 0.058 0.181 0.022
The next prime year is 2011, followed by 2027
