As for the coming holiday-shortened week, it tends to be a good one for stock investors. The S&P 500 has risen between Christmas and New Year’s Eve on 73% of occasions in its 94-year history, with a median return of 0.7%, according to Dow Jones Market Data. That could cut the S&P 500’s 2022 loss, currently at 19.3%. There’s another historical trend in investors’ favor. When the index declines 20% or more in a calendar year, it’s been up two-thirds of the time in the next year, per Dow Jones Market Data. The following 12 months have seen a median gain of 24.3%.
