Yearly All Time Highs, from Kim Zussman

I checked SP500 weekly closes for new all time highs per year, back to 1951.  2017 was second highest total weekly ATHs in the series (also see attached plot):

year  Count

1951     14

1952     13

1954     25

1955     20

1956      6

1958     10

1959     13

1961     20

1963     10

1964     23

1965     12

1966      3

1967      7

1968      9

1972     10

1973      1

1980     11

1982      1

1983     13

1985     20

1986     13

1987     18

1989      7

1990      2

1991     12

1992      6

1993      9

1994      3

1995     28

1996     14

1997     20

1998     16

1999     13

2000      1

2007      4

2013     18

2014     20

2015      6

2016      8

2017     27

And the outlook? Sorting years with at least 20 new weekly ATHs, here is comparison of mean returns for years following these years - along with mean returns for all years:

One-Sample T: nxt yr, all yr

Test of mu = 0 vs not = 0

Variable N Mean StDev SE Mean 95% CI T P

nxt yr 7 0.111 0.137 0.051 (-0.015, 0.237) 2.14 0.076

all yr 65 0.085 0.162 0.020 ( 0.045, 0.125) 4.24 0.000

so the return is +11% vs +8.5% for all years. No bearishness here.

I’m wondering how studies with a year timeframe can be used practically in a speculation or trading system. Always in long can’t use it and in a trading system there’s too few observations in your lifetime to justify it. After all there’s sizable chance that the market bucks the statistics and then you’re out a year and are you now waiting for the next year? Year studies are used by arm chair market participants who are always in long and are just justifying their always in long.
