Jeff Hisch of The Stock Trader's Almanac, in the last interview of him I saw transcribed, considers the time after Good Friday and Easter to generally be bearish.
If one looks at Good Friday during a bear market year, such as 2002 or 1987, one sees the market tends to go down somewhat. The following figures are adjusted close prices per Yahoo Finance: 2002: SPY was 100.81 on Maundy Thursday (a/k/a Holy Thursday) and 98.72 12 days later. 1987: ^DJI was 2275.99 on Maundy Thursday and 2231.96 12 days later. I used 12 days later so the check date was a Tuesday.
On a bigger theme than investing, I hope your Easter weekend was joyful and included contemplation of how needy all of us in this world are for something eternal and better.
