Stock Market Today: Nasdaq 100 Jumps 1.44% After AI Selloff as Opening Rally Adds an Estimated $470B

US stocks rebound after last week's AI selloff, with Nasdaq 100 up around 1.4%. Dan Ives sees opportunity, while strategists warn of more volatility.

Key takeaways

  • Nasdaq rebounds after steep AI-driven weekly losses
  • Opening rally reportedly adds $470 billion in value
  • Wall Street analysts disagree over recovery's sustainability

U.S. stocks rebounded sharply on Monday, October 19, as investors returned to artificial intelligence and semiconductor shares following last week's technology selloff, which erased substantial market value and raised concerns about the sustainability of the AI investment boom.

The Nasdaq 100 advanced approximately 1.44% in an early trading snapshot, while a market alert estimated that roughly $470 billion was added to U.S. equity valuations at the opening bell. The capitalization figure represents a point-in-time estimate rather than realized investment inflows or a confirmed full-session gain.

The Nasdaq Composite opened 0.98% higher at 26,395.29, while the S&P 500 climbed 0.57% to 7,702.77. The Dow Jones Industrial Average initially slipped 0.05%, highlighting the rally's concentration in technology stocks.

Nasdaq Rebounds After AI Stocks Suffer Heavy Losses

Monday's buying followed a difficult week in which the Nasdaq Composite lost approximately 4.5%, pressured by investor concerns about expensive AI infrastructure, rising corporate borrowing costs and the profitability of enormous computing investments.

Semiconductor stocks experienced particularly severe selling. The Philadelphia Semiconductor Index fell approximately 10% during the week, following an earlier $1.64 trillion selloff across major chip manufacturers.

Nvidia, AMD and Intel participated in Monday's recovery, with chipmakers among the strongest early performers. The reversal suggests investors are willing to reconsider AI-related valuations following the rapid decline.

Nasdaq-100 fell 5.49% last week before rebounding 1.44% on Monday.

However, the rebound has not eliminated the financial concerns driving the correction.

CoreWeave provides a prominent example. The company suffered a steep weekly decline after yields on its 2031 bonds exceeded 16%, reflecting increased doubts about debt-funded AI expansion.

Dan Ives Sees Opportunity, but Technical Analysts Remain Cautious

Yorkville analyst Dan Ives has argued that the AI stock selloff presents an opportunity to acquire companies positioned to benefit from long-term computing demand.

In recent CNBC commentary, Ives described the pullback as overdone and pointed to Microsoft, Nvidia, Palantir and CrowdStrike among companies he favors.

His broader argument is that demand for AI infrastructure remains substantial even if investors are temporarily reassessing valuations.

That view contrasts with warnings from BTIG strategists, who have questioned whether the rebound can persist while the technical condition of the market remains fragile.

Piper Sandler's Craig Johnson has separately highlighted deteriorating market breadth and a breakdown below an important Nasdaq uptrend. His analysis indicates that a few recovering mega-cap stocks may not be enough to establish a sustained market reversal.

The previous AI stock decline demonstrated how quickly weakness can spread across semiconductor manufacturers when investors begin reducing exposure simultaneously.

Big Tech Earnings Could Determine Whether the Rally Continues

Wall Street's next major test arrives this week, when several technology companies report quarterly results.

Meta is scheduled to release earnings on October 21, with analysts expecting approximately $63.3 billion in revenue and management facing scrutiny over its annual capital spending plans reaching as high as $145 billion.

Investors will be watching whether stronger advertising revenue and AI-driven efficiency gains can justify accelerating infrastructure costs.

The tension between AI optimism and debt concerns also extends to institutional positioning. Recent retail investment data showed $700 million in net purchases of neocloud stocks during a measured week, even as credit markets became increasingly cautious.
