The holiday shopping season kicks off with Thanksgiving, Black Friday, and Cyber Monday. Historically, the week after Black Friday has seen a 0.66% gain on average in the S&P 500 Index, with 69% of weeks being positive. Cyber Monday, however, has been a bad day for the index, with 10 out of 13 years showing losses.

When the SPX gained at least 1% after Thanksgiving week, it went on to average a 3.9% return over the next three months, with 77% of returns positive. When the week was negative, it averaged a 4.1% loss over the next three months, with only 33% of returns positive.

Looking at the rest of the year, when post-Thanksgiving week was down 1% or more, the SPX gained 1.6% for the year, with 83% positive. When the week was up by 1% or more, it gained 0.52% on average, with 69% of returns positive. This indicator may not work in the short term due to other factors at play.

Some SPX retailers and stocks relevant to the holiday shopping season have performed well during the week after Thanksgiving. Hewlett Packard Enterprises (HPE) and CME Group (CME) have been positive every year, while Amazon.com (AMZN) and Walmart (WMT) have been near the bottom of the list. Target (TGT), Nike (NKE), and Ross Stores (ROST) have tended to be positive.
