According to my system the highest risk window for a turn or acceleration of the current trend next week is Monday morning the 31st thru Wednesday morning the 2nd centered around the holiday.
Last week I noted a similar risk window centered around the Christmas holiday and sure enough Santa Claus (a.k.a. the PPT) brought the good bulls the biggest rally in history straight down the chimney of all those wicked bears. The DJIA futures bottomed right on Christmas day: https://finviz.com/futures_charts.ashx?t=YM&p=h1
The jury is still out on the 28th risk window. It certainly looked like the trepidatious start of a turn back down, but I strongly suspect the PPT will not give the grinch bear any quarter. Having been atom bombed on the 26th, the poor wretched ursine beast's future probably lies as a pelt on the floor of the bull's house to warm his cloven hooves.
Happy New Year,
Douglas
