According to @StockMKTNewz, the post highlights the history of the Santa Claus Rally that traders track each year for short-term equity momentum signals (source: @StockMKTNewz). The Santa Claus Rally is defined as the last five trading days of December and the first two trading days of January, a seven-session window first documented by Yale Hirsch and tracked in the Stock Trader’s Almanac (source: Stock Trader’s Almanac). Market participants monitor whether this period finishes positive as a sentiment gauge for near-term risk appetite in U.S. stocks based on the Almanac’s long-run seasonality records (source: Stock Trader’s Almanac). For crypto, this equity seasonality matters because BTC has at times shown a materially positive correlation with U.S. equities since 2020, which can transmit risk-on or risk-off impulses across markets (source: Bank for International Settlements).
