The stock market extended its rally during the holiday-shortened week, with the S&P 500 (+1.4%), Nasdaq Composite (+2.4%), and DJIA (+0.9%) all finishing at fresh record highs. Leadership remained concentrated in technology and AI-related stocks, though improving participation across small- and mid-cap shares also helped support the advance.
The information technology sector (+4.6%) was the clear leader, powered by continued strength in semiconductors, software, and AI infrastructure names. Investors continued rewarding companies tied to AI spending trends. Micron surged after a bullish analyst call early in the week, while onsemi and several hardware-related names also posted strong gains.
Software stocks were another major area of strength, fueled by strong earnings reactions and AI optimism surrounding names such as Snowflake. Microsoft also provided major support after reports that the company is preparing to unveil a new AI-powered coding framework.
Hardware stocks became a major leadership group later in the week following blowout earnings reports from Dell and NetApp, which sparked broad gains across server, storage, and enterprise infrastructure companies. That helped offset more mixed action from NVIDIA and several other semiconductor bellwethers, which at times struggled to build on their recent rallies despite continued enthusiasm surrounding the AI trade.
Outside of technology, several economically sensitive groups benefited from falling Treasury yields and sharply lower oil prices. The Russell 2000 (+1.8%) and S&P Mid Cap 400 (+1.4%) both outperformed the broader market, reflecting improving risk appetite beneath the surface. Consumer discretionary stocks (+1.5%) also moved higher, aided by strength in cruise lines, airlines, retailers, and homebuilders. Declining yields improved sentiment toward housing-related names.
A major macro driver throughout the week was the continued decline in oil prices amid optimism surrounding negotiations between the U.S. and Iran. WTI crude oil fell roughly 11.5% for the week, pressuring the energy sector (-5.4%), which finished as the market's weakest-performing group by a wide margin. The retreat in oil prices also helped ease inflation concerns and contributed to lower Treasury yields, with both the 2-year and 10-year Treasury yields declining 11 basis points during the week.
The softer rate backdrop helped offset somewhat mixed economic data. Inflation remained elevated in the latest PCE report, while downward revisions to Q1 GDP and softer housing data reinforced concerns about slowing economic momentum. At the same time, durable goods orders were surprisingly strong, labor market data remained relatively stable, and the Chicago PMI unexpectedly returned to expansion territory.
Defensive sectors generally lagged during the week's risk-on advance. Consumer staples (-3.2%) posted the steepest decline outside of energy following several disappointing earnings reactions, including weakness in Costco. Utilities (-2.1%) and real estate (-1.4%) also underperformed, while financials (-0.7%) and health care (-0.3%) finished slightly lower overall.
Overall, the week reinforced the market's strong upward momentum as investors continued rotating aggressively into AI beneficiaries, software leaders, and technology infrastructure names. At the same time, falling oil prices and lower Treasury yields helped broaden participation across smaller-cap and cyclical areas of the market, allowing equities to push deeper into record territory despite mixed economic data and ongoing geopolitical uncertainty.
