The Nasdaq Composite surged past 27,000 to a fresh all-time high on Monday, driven by soaring artificial intelligence enthusiasm and major buyout announcements. This milestone came even as 10-year U.S. Treasury yields touched multi-decade highs at 5.35%, signaling a distinct divergence between mega-cap tech momentum and broader market caution.
Wall Street kicked off the week with a clear split between high-flying growth equities and a heavily pressured bond market. While the Nasdaq Composite climbed to 27,477.31, government debt sold off sharply. The yield on the 10-year U.S. Treasury touched 5.35% before easing slightly to 5.31%, sitting at its highest level since 2002. At the same time, the 30-year yield breached 5.7%.
Despite borrowing costs reaching levels not seen in over two decades, equity investors shrugged off the bond market pressure. Trading activity also received a lift from multibillion-dollar corporate buyout announcements that buoyed sentiment across technology and software sectors. Even as multi-decade peak yields threatened equity valuations in the final months of 2026, animal spirits drove the stock market higher on Monday as investors rushed into tech despite accelerating government bond sell-offs. Brent crude fell 1% to $100 a barrel as G7 nations released oil stocks and exports from Middle East producers increased, easing supply tightness concerns. Meanwhile, the S&P 500 finished Monday’s session at 7,773.95—marking a 51.23-point or 0.66% increase over Friday’s 7,722 closing level—while the Dow Jones Industrial Average gained 91 points, representing a 0.2% advance to reach 51,268.
Mega-Cap Tech and Artificial Intelligence Giants Lead the Charge
Technology leaders dominated the trading session as artificial intelligence demand continued to funnel capital toward the sector’s largest players. Nvidia shares reached all-time highs, with the company’s market capitalization approaching $6 trillion amid insatiable demand for AI-powering chips. In tech, SpaceX jumped 6% after Morgan Stanley said the stock looked “cheap,while Microsoft rose more than 2% after Melius Research issued a
buy” rating, and other hyperscalers and chip giants rose amid AI optimism to start the week.
Other notable movers included SpaceX, which jumped more than 7% amid reports that the company is eyeing a natural gas pipeline in Florida to fuel Starship launches alongside its growing artificial intelligence ambitions. Microsoft climbed over 2% following an analyst upgrade, while Broadcom, Meta Platforms, and Tesla posted solid gains. Broadcom climbed 2.1%, Nvidia and Tesla rose over 2% each, and Meta and Microsoft rose more than 1% each.
Small Caps and Equal-Weighted Indexes Feel the Pinch of High Rates
While the market-value-weighted Nasdaq and the S&P 500 marched toward record territory, smaller companies experienced a starkly different reality. Data analyzing the broader market revealed that a significant percentage of U.S. small caps closed at least 20% below their summer highs. Strategists noted that equal-weighted benchmarks continue to lag. On Monday, October 5, 2026, the Nasdaq Composite closed at a record 27,477.31, but beneath the surface 206 stocks hit new 52-week lows while just 46 hit new highs.
Federal Reserve Minutes and Earnings Season Lie Ahead
Market participants turned their attention toward upcoming macroeconomic data releases and corporate earnings reports.
Traders awaited the release of the Federal Open Market Committee’s September meeting minutes on Wednesday for further clues on policymakers’ thinking regarding inflation and the future rate path. Analysts have big expectations for earnings season, forecasting growth of nearly 30% from a year earlier for S&P 500 companies according to FactSet data, which would mark the third straight quarter of growth above 25% for the index. Daniela Hathorn of Capital.com noted that data helped reduce expectations for another Fed hike in October, with traders pricing only about a 20% chance of an October increase, while Morgan Stanley Wealth Management investment chief Lisa Shalett noted in a note to clients that bonds have faced heightened volatility over the past six weeks.
