US stocks traded sharply lower to start the week on Tuesday, with the S&P 500 Index posting its largest daily decline since October amid renewed fears of a global trade war after President Trump announced that he would impose new tariffs on European nations that opposed the U.S. purchasing or otherwise taking control of Greenland. Stocks reversed course on Wednesday after Trump said that he and NATO Secretary General Rutte had “formed the framework of a future deal with respect to Greenland” and that he would no longer “be imposing the Tariffs that were scheduled to go into effect on February 1st.”

US equity indexes were mixed for the week, with small-cap and value stocks adding to their YTD leads over large-cap and growth-oriented shares. The Russell 2000 index advanced, reaching all-time high during the week, while large-cap indexes pulled back from the prior week’s record levels. Value stocks outpaced their growth counterparts for the third straight week. Q4 earnings season kicked off during the week with several big banks reporting Q4 results.

US equities advanced in the first full trading week of the year as investors largely looked past mounting geopolitical tensions, pushing most major indexes to all-time highs. Small-cap and value shares outpaced the large-cap growth stocks that have led returns in recent years, while an equal-weighted version of the S&P 500 Index outperformed its market cap-weighted counterpart. Of the major indexes, the Russell 2000 Index performed best, adding 4.62%, while the S&P 500 performed worst but still gained 1.57%. Stocks of aerospace & defense companies and homebuilders were volatile after several announcements by the Trump administration.

U.S. stocks declined during the holiday-shortened week. The Nasdaq Composite performed worst for the week, followed by the Russell 2000 and S&P 500 indexes. The Dow Jones Industrial Average and S&P MidCap 400 Index held up best but still shed 0.67% and 0.71%, respectively. Within the S&P 500 Index, the energy sector outperformed as heightened geopolitical tensions drove oil prices higher. On the US macro side, lower mortgage rates and wage growth fuel homebuyer momentum, as pending home sales Index rose 3.3% in November, marking the largest month-over-month jump since February 2023.

U.S. stocks advanced during the holiday-shortened week, with the S&P 500 Index and Dow Jones Industrial Average both hitting record highs. News flow and trading volumes were generally light throughout the week, but some recent favorable economic data alongside artificial intelligence (AI) optimism appeared to support positive sentiment. The small-cap Russell 2000 Index was the worst performer of the major indexes, finishing the week 0.19% higher. On the macro front, the U.S. economy expanded at the fastest pace in two years during Q3, as U.S. real GDP grew at an annual rate of 4.3%, ahead of the second quarter’s 3.8% growth rate and well above estimates for around 3%.

The S&P 500 index finished the week little changed, while the Nasdaq added 0.48%. The Russell 2000 Index performed worst, declining 0.86%, followed by the Dow, which shed 0.67%. Equities started the week broadly lower but reversed course toward the end of the week, supported in part by an encouraging US inflation report as well as strong earnings results from semiconductor manufacturer Micron Technology that seemed to help shift AI-related sentiment. On the macro side, US unemployment rate rose to 4.6% in November, the highest level in over four years while US core inflation dropped to slowest pace since early 2021. December business activity growth slowed to a six-month low. US Treasuries yields generally decreased across most maturities.

Most US stock indexes rose and hit all-time highs during the week, supported by the Federal Reserve’s 3rd consecutive interest rate cut and commentary from central bank officials that some investors interpreted as less hawkish than feared. The small-cap Russell 2000 Index, performed best, adding 1.19%, followed by the Dow Jones Industrial Average’s 1.05% gain. Meanwhile, the S&P 500 Index pulled back sharply on Friday and erased its gains from earlier in the week. Renewed concerns regarding technology stock valuations and questions around whether elevated spending on AI infrastructure will pay off weighed on the Nasdaq Composite index, which fell 1.62% over the week.

Major U.S. stock indexes finished the week higher, amid investor hopes for an interest rate cut from the Fed at its upcoming meeting. The Nasdaq Composite led the major indexes higher, advancing 0.91%, followed by the small-cap Russell 2000 Index, which rose 0.84%. The S&P 500 Index lagged but still posted a modest gain for the week. Mag7 stocks outperformed the S&P 493. On the macro front, ISM Manufacturing activity index continues to slide while ISM services expand at fastest pace since February. ADP Private payrolls dropped by most since 2023. US PCE inflation index rose 0.3% month over month in September, in line with August’s reading.

U.S. stock indexes finished the holiday-shortened week higher, boosted by dovish comments from some Fed officials and several weaker-than-expected economic reports that seemed to reinforce the idea that a December rate cut remains on track. Small-cap stocks outperformed their large-cap peers, as the Russell 2000 Index advanced 5.5%. The Nasdaq Composite also posted strong returns, rebounding from the prior week’s sell-off as concerns regarding elevated valuations and spending on AI appeared to take a back seat to optimism around the growth potential from the technology. In economic news, U.S. retail sales increased by 0.2% in September (below +0.4% estimates). September PPI rose 0.3% in September, in line with estimates.

Despite some good news during the week from both corporate earnings reports and government economic data, U.S. equity markets finished the week lower. The sell-off appeared to be driven by worries about lofty stock valuations and concerns around whether AI will generate enough profits to justify the massive spending that companies have poured into supporting the developing technology. The Nasdaq Composite had the largest losses, while the Russell 2000 held up better but still lost ground. The S&P 500 Index finished about 4.4% lower than the record high it achieved in late October. A rebound on Friday helped ease the losses that the major benchmarks suffered earlier in the week.
