Good Friday and the Stock Market
The U.S. markets will be closed on 04/02 for Good Friday. This is a quick look at how the market fares around this holiday.
Note: this study is included on our new Monthly Seasonality Map.
Just the Numbers
Between 1950 and 2009, the S&P 500 has risen on the day-before GF 67% of the time for an average gain of 0.34%, but risen on the day-after only 43% of the time for an average loss of -0.18%.
Numbers for the number lovers…
Looking just at these long run averages, it appears that the market is strong the day before, and weak the day after, Good Friday.
But readers know I hate just looking at averages because they don’t tell us how consistent the observation has been or whether it’s waxing or waning, so to answer those questions, in the following chart I’ve assumed a trader was only long the S&P 500 index on either the day before (green) or the day after (red) Good Friday, each year from 1950.
What does the chart tell us?
The U.S. market has been consistently bullish the day prior to Good Friday (green), and the observation does not appear to be waning in effectiveness. I like it.
The market has tended to be bearish the day after the Good Friday holiday (red), but almost all losses came between the late 70′s and 90′s. This day-after GF effect has been much less consistent and might not be exploitable in today’s market.
P.S. I didn’t show it above, but the TWO days before or after GF have not been consistently bullish or bearish.
