Weakness Day After Labor Day & Sell Rosh Hashanah
In the last 21 years, only Russell 2000 has registered an average gain of 0.04% on the Tuesday after the long Labor Day weekend. DJIA, S&P 500 and NASDAQ have struggled with negative average performance. NASDAQ and Russell 2000 have been up five of the last nine years, but DJIA, S&P 500, NASDAQ and Russell 2000 all have fallen for the last four years on Tuesday. On Wednesday the market’s performance has been varied. DJIA has performed the best, up 76.2% of the time with an average gain of 0.33%. S&P 500 is worst, up only 47.6% of the time with an average gain of 0.25%. NASDAQ has a better record up 52.4% of the time on Wednesday, but a smaller average gain of 0.14%.
Sell Rosh Hashanah, Buy Yom Kippur
As the High Holidays approach you may remember the old saying on the Street, “Sell Rosh Hashanah, Buy Yom Kippur.” It gets tossed around every autumn when the “high holidays” are on the minds of traders as many of their Jewish colleagues take off to observe the Jewish New Year and Day of Atonement.
The basis for this, “Sell Rosh Hashanah, Buy Yom Kippur,” pattern is that with many traders and investors busy with religious observance and family, positions are closed out and volume fades creating a buying vacuum. Even in the age of algorithmic, computer, and high frequency trading these seasonal patterns persist as humans still need to turn the machines on and off and feed them money or take it away – and these algorithms and trading programs are written by people so the human influence is still there.
Holiday seasonality around official market holidays is something we pay close attention to (page 98 Stock Trader’s Almanac 2021). Actual stats on the most observed Hebrew holidays have been compiled in the table here. We present the data back to 1971 and when the holiday falls on a weekend the prior market close is used. It’s no coincidence that Rosh Hashanah and Yom Kippur fall in September and/or October, two dangerous and sometimes opportune months.
Perhaps it’s Talmudic wisdom but, selling stocks before the eight-day span of the high holidays has avoided many declines, especially during uncertain times. While being long Yom Kippur to Passover has produced 64% more advances, half as many losses and average gains of 7.0%. This past year DJIA gained 19.9% from Yom Kippur 2020 to Passover 2021.
This year the high holidays arrive early on Labor Day eve, September 6, and end Thursday September 16 with Yom Kippur at mid-month one of the strongest days September. But with the market in full rally mode on easy Federal Reserve money and free Federal Government fiscal stimulus month selling ahead of the Jewish High Holidays could trigger a mild correction of 5% or so. The end of September after Triple Witching is notoriously the weakest part of the month, so it may be more prudent to “buy” later in the month.
