According to LPL financial "Does the 1st trading day of the year matter? Sounds random, but ...
Past 20 years, on the 1st day of a new year the S&P 500 has been higher 10 times and lower 10 times.
Full year return if up the first day? +14.2%.
Full year return if down the first day? -0.6%"
We will see if the Dow follows suit.
