The S&P 500 is poised for a December rally, driven by Federal Reserve rate cuts and the conclusion of quantitative tightening, with projections suggesting a rise to 7,200. In contrast, Bitcoin has underperformed, falling 30% from its peak and down 2% year-to-date. Vanguard's S&P 500 ETF (VOO) recorded $20.82 billion in inflows in November, its second-largest monthly inflow in four years. Analysts caution that Bitcoin may encounter further downside as the Fed's easing cycle progresses, echoing historical market trends.
