The three U.S. stock indexes were all nearly unchanged, paring mild early declines and interrupting what looked early this week like a nascent "Santa Claus rally," in which shares get a seasonal boost from low liquidity, tax-loss harvesting and investment of year-end bonuses. With only a handful of trading days remaining in the year, the Nasdaq, S&P 500 and the Dow have scored respective gains of 33%, 26% and 14% in 2024. The major concerns for 2025 are the extent of the Fed's monetary easing, Trump's tariffs and other policies, and various geopolitical tensions.
