According to @CNBC, December will begin with investors owning relatively little stock, raising the question of a year-end rally as underweight positioning can force re-risking if momentum turns higher (source: CNBC). For trading, the key tell will be whether equity inflows, advancing breadth, and sustained upside follow-through confirm a positioning squeeze into month- and year-end (source: CNBC). Crypto market participants should monitor U.S. equity risk sentiment during this period, as shifts from underweight to neutral/overweight in stocks can influence demand for higher-beta assets (source: CNBC).
