Rallies for Nvidia and Big Tech help Wall Street nearly erase last week’s loss

U.S. equities largely recovered last week's losses, with the S&P 500 climbing 1.5% and the Nasdaq composite jumping 2.3%, primarily driven by a strong rebound in Big Tech and AI-related stocks. Nvidia surged 5.8%, while Taiwan Semiconductor Manufacturing Co. and Palantir Technologies also saw significant gains following positive revenue reports and profit beats. Conversely, health insurers like Humana and Centene declined due to uncertainty surrounding expiring healthcare tax credits and potential government shutdown impacts. The broader market was supported by approximately four out of five S&P 500 companies exceeding profit expectations and providing strong future forecasts, pushing 2026 earnings estimates back to pre-tariff announcement levels.

Analysis

Wall Street experienced a significant rebound, with the S&P 500 climbing 1.5% and the Nasdaq composite jumping 2.3%, largely recovering last week's losses. This surge was primarily driven by Big Tech and AI-related stocks, notably Nvidia (NVDA) which leaped 5.8%, and Palantir Technologies (PLTR) which gained 8.8% following a profit beat. Taiwan Semiconductor Manufacturing Co. (TSM) also rose 3.1% after reporting a nearly 17% year-over-year revenue increase for October.

The broader market strength is underpinned by robust corporate earnings, with approximately four out of five S&P 500 companies surpassing profit expectations. This performance, coupled with strong forward guidance from companies, has pushed 2026 earnings estimates back to pre-tariff announcement levels, signaling underlying fundamental health despite concerns over AI stock valuations.

However, sector-specific headwinds emerged, particularly in healthcare, where insurers like Humana (HUM), Elevance Health (ELV), and Centene (CNC) fell between 4.4% and 8.8%. This decline is attributed to ongoing uncertainty regarding expiring healthcare tax credits and potential government shutdown impacts, highlighting policy-driven risks within the sector.

Key Decisions for Investors

• Closely monitor the sustainability of valuations in AI-driven technology stocks, particularly given rapid price appreciation and historical comparisons.
• Evaluate exposure to the healthcare insurance sector due to ongoing policy uncertainty regarding tax credits and potential government actions.
• Prioritize companies with consistent earnings beats and robust forward guidance, as these fundamentals are underpinning current market strength.
