As far as I know, in the United States, the holiday for Christmas is 1.5 days, and New Year's Day is three days. However, these two holidays are very close together, and some small and medium-sized enterprises extend their holiday period from the 22nd to January 5th. This includes many institutions and trust companies, so the trading volume during this period is quite low. However, with only two days left in December, I feel there will be a slight rebound to wrap things up.
