Today’s Chart of the Day was shared by Frank Cappelleri (@FrankCappelleri) and EquityClock.com. The chart shows the S&P 500's average historical performance over the past 20-years. The S&P 500 followed its historical average quite closely in 2021, so we want to continue to pay attention to seasonality. Over the past 20-years, the S&P has historically started off strong in January, only to roll over mid-month and finish lower. In a comment, Frank explained, "The S&P 500 has advanced in January just 9 out of 20 years (45% of the time), with an average move of -0.3%. As you can see from the table on the right, there have been big moves in January in both directions over the last 20 years. The index logged a move less than +/-1% only one year: 2020."
