I assume low volume maybe? Fed Wednesday coming so I am guessing sideways or slightly up…
Just looked it up, last December 12th, SPX 5 pts up high, 6 points down low, closing 2 pts down.
Actually the bigger one was in 2016 January 22-23rd, and the market rallied 30 pts…That one was 27″. So maybe no snow effect whatsoever…
