AI stocks lead Wall Street rebound as Nvidia, Palantir surge and S&P 500 claws back last week’s losses

U.S. equities rallied, with the S&P 500 gaining 1.3% and the Nasdaq 2.1%, largely driven by a rebound in AI-related tech stocks like Nvidia (+4.8%) and Palantir (+8.9%) following last week's declines. This recovery was supported by strong corporate earnings, as approximately 80% of S&P 500 companies beat profit expectations. However, gains were tempered by significant declines in health insurers due to uncertainty surrounding healthcare tax credits and the ongoing government shutdown, which also raises concerns about delayed economic data and its potential impact on Federal Reserve interest rate cut expectations. International markets also saw broad rallies.

Analysis

U.S. equities experienced a significant rebound, with the S&P 500 climbing 1.3% and the Nasdaq composite rising 2.1%, largely recovering from last week's losses. This rally was primarily fueled by a strong resurgence in AI-related technology stocks, notably Nvidia, which gained 4.8%, and Palantir Technologies, up 8.9%, following recent criticisms of their rapid valuation increases. Taiwan Semiconductor Manufacturing Co. (TSM) also saw its U.S.-traded stock rise 3.1% on a nearly 17% year-over-year revenue increase in October, despite this representing a slowdown from prior growth.

The market's gains were partially offset by substantial declines in health insurance stocks, including Humana (-3.3%), Elevance Health (-3.8%), and Centene (-7.6%). This sector weakness stems from ongoing uncertainty regarding the extension of healthcare tax credits and President Trump's recent comments, exacerbated by the protracted government shutdown. The shutdown's impact extends to operational disruptions, such as flight cancellations, and delays in critical economic data releases.

The absence of key economic reports due to the government shutdown creates uncertainty for monetary policy, as traders lack current data to assess the Federal Reserve's path on interest rate cuts. While the market widely expects continued rate reductions to support a slowing job market, the Fed has indicated potential halts if inflation worsens, making timely data crucial. Strong corporate earnings, with approximately 80% of S&P 500 companies beating profit expectations and providing robust forecasts, are currently serving as a primary market driver.

Key Decisions for Investors

• Monitor the resolution of the government shutdown and its potential impact on economic data releases, which could influence Federal Reserve interest rate policy.
• Evaluate exposure to AI-related growth stocks given their recent volatility and the ongoing debate regarding valuations, while acknowledging strong corporate earnings.
• Assess positions in the healthcare sector, particularly health insurers, due to heightened policy uncertainty surrounding tax credits and political rhetoric.
