Market Rally Regains Momentum as Mega-Caps Lead Broad Advance

Stocks began the week with strong gains, powered by renewed buying in mega-cap and tech names. The S&P 500 rose 1.5%, the Nasdaq Composite surged 2.3%, and the Dow Jones Industrial Average added 0.8%, bringing the major averages within sight of flat month-to-date performance.

Optimism returned early after the Senate moved closer to ending the government shutdown, passing a procedural vote that set the stage for a final funding deal. Although policy progress provided a modest backdrop, the day’s real catalyst came from a powerful resurgence in the market’s largest growth names.

The Vanguard Mega-Cap Growth ETF climbed 2.5%, helping the information technology (+2.7%) and communication services (+2.5%) sectors lead the charge. The AI trade came roaring back as the PHLX Semiconductor Index gained 3.0%, driven by strength in Micron (+6.4%), NVIDIA (+5.8%), and AMD (+4.6%), which reports tomorrow.

Palantir Technologies stood out with an 8.8% rally, reclaiming its 50-day moving average, while Alphabet (+3.9%) extended its recent momentum on optimism surrounding the upcoming release of its Ironwood AI chip. The consumer discretionary sector also benefited, with Tesla (+3.7%) and Amazon (+4.0%) both lifting the group.

Elsewhere, gains were widespread: eight of the eleven S&P 500 sectors finished higher, while only consumer staples (-0.3%), utilities (-0.1%), and real estate (-0.1%) slipped modestly as investors rotated away from defensives. Breadth was notably strong, with advancers leading decliners nearly two-to-one on both the NYSE and Nasdaq—evidence of broad participation beyond the mega-caps.

Smaller names also joined the rally, with the Russell 2000 up 1.1% and the S&P Mid Cap 400 up 0.8%. The Invesco S&P 500 High Beta ETF’s 1.6% gain underscored a return of risk appetite.

While headlines about the government funding deal offered a mild tailwind, today’s rally was more about sentiment—an affirmation that investors remain willing to buy dips in the market’s largest names. With AI optimism and mega-cap momentum back in play, the week began on a confident note for the bulls.

Our FTinvest 11 model portfolio extended its recent momentum, closing up 0.22% at 865.20 to start the week on a steady note. The index held firm in positive territory throughout the session, showing resilience even as broader market benchmarks traded with mixed direction.

The advance was supported by renewed buying in several key holdings. Gains were more moderate compared to last week’s surge, but the session’s tone remained constructive, with the index consolidating near record levels.

While some benchmark indices saw intraday volatility, FTinvest 11 maintained a relatively stable upward trajectory — a sign of balanced participation across components. The index’s ability to preserve recent gains highlights investor confidence and continued sector rotation into its leading names.

Overall, the session reinforced FTinvest 11’s leadership trend, keeping it well ahead of the broader market as the portfolio continues to display steady relative strength.
