The “Santa Claus Rally” Effect
The “Santa Claus Rally” technically refers to the last five trading days of the year and the first two of the new year. December 27th typically falls squarely in this window.
Yale Hirsch of the Stock Trader’s Almanac discovered this pattern in 1972. While not guaranteed, the S&P 500 has historically risen 1.3% on average during this 7-day period.
