Key takeaways

  • S&P 500 rebounds as AI stocks recover from losses
  • Nvidia and CoreWeave lead gains across technology shares
  • Inflation and Fed rate concerns continue pressuring markets

The US stock market rebounded on Wednesday, November 11, as Nvidia, CoreWeave and other artificial intelligence stocks rallied following an inflation-driven selloff. The S&P 500 climbed approximately 0.9%, supported by renewed buying interest in semiconductor and AI infrastructure companies.

The Nasdaq Composite advanced around 1.4%, while the Dow Jones Industrial Average slipped 0.1%, highlighting the technology sector's outsized contribution to the recovery. The gains followed Tuesday's inflation-driven selloff, when stronger-than-expected consumer price data intensified concerns about Federal Reserve interest rate hikes.

Why Is the S&P 500 Up Today?

The S&P 500 recovered as technology investors shifted attention toward corporate earnings and continued AI infrastructure demand, despite uncertainty surrounding interest rates.

CoreWeave was among Wednesday's strongest performers, jumping approximately 10.7% after reporting better-than-expected quarterly results. The company generated $3.66 billion in third-quarter revenue, up 168% year over year, and raised its annual revenue outlook to between $13 billion and $13.3 billion.

The results reinforced confidence in AI computing demand, although CoreWeave's projected $37 billion to $39 billion in annual capital expenditures underscored the extraordinary cost of expanding infrastructure. Its latest earnings performance helped support sentiment across technology shares.

Nvidia stock advanced approximately 2.9%, while Micron Technology and Broadcom gained around 5.6% each. The semiconductor rebound followed recent pressure on Nvidia amid analyst reassessments and concerns about AI valuations

Inflation and Treasury Yields Threaten the Recovery

Despite Wednesday's gains, investors remain concerned that persistent inflation could keep interest rates elevated longer than previously anticipated.

October consumer prices increased 0.4% month over month, while core inflation advanced 0.3%. The inflation report pushed Treasury yields higher, with the benchmark 10-year yield approaching 5% during the previous session.

Elevated borrowing costs can weigh heavily on technology companies, particularly those financing expensive infrastructure expansion. Rising yields also reduce the present value of future corporate earnings, creating additional pressure on growth-stock valuations.

The bond market was closed Wednesday for Veterans Day, while US equity markets continued trading.

Can the Stock Market Rally Continue?

The recovery suggests investors remain willing to buy leading AI companies when earnings demonstrate resilient demand, even as concerns about valuations and capital spending persist.

Recent semiconductor market weakness has created opportunities for selective rebounds, while continued investment in AI infrastructure provides another source of optimism.

Meanwhile, TSMC's AI investment plans highlight how major chip manufacturers are positioning themselves to benefit from demand linked to OpenAI, Anthropic and other technology companies.

Whether the S&P 500 can sustain its recovery will depend partly on upcoming economic data, corporate earnings and expectations for Federal Reserve policy. For now, AI-related buying has helped offset broader market concerns, although Wednesday's gains remain concentrated in technology stocks.
