Fading AI Confidence—Not Bond Yields—Poses Biggest Stock Market Threat, Says Bank of America

TLDR

• Bank of America selected Nvidia, Intel, Marvell, Micron, and Lam Research as its preferred AI chip stocks for Q4
• The firm increased its AI data center market projection to $2.2 trillion by 2030, revising upward from $1.8 trillion
• BofA strategists warn that weakening AI sentiment, rather than climbing bond yields, represents the most significant current stock market threat
• The S&P 500’s top 20 performers added $1.7 trillion in market cap since late August while the remaining 480 stocks shed $1.9 trillion collectively
• Semiconductor valuations appear reasonable, with the SOX index trading beneath its average level since ChatGPT’s debut

Bank of America issued a note identifying its preferred semiconductor investments for the current quarter. The firm’s five selections include Nvidia, Intel, Marvell, Micron, and Lam Research.

NVIDIA Corporation, NVDA

The firm’s analysts constructed these recommendations using historical seasonal patterns. Their research revealed that chip stocks have typically delivered their strongest performance during the fourth and first quarters since 2010.

Throughout this period, semiconductor equities outperformed the broader S&P 500 by an average of 300 to 500 basis points. The analysts also identified specific near-term catalysts for each recommendation.

Catalysts Behind Each Selection

Nvidia faces multiple tailwinds including its upcoming GTC tradeshow events and an expansion of its share repurchase program. Intel stands to benefit from increased demand linked to agentic CPU applications and potential new foundry agreements.

Micron plans to initiate a fresh buyback program on December 9. Marvell has scheduled an Analyst Day for October 6 while experiencing expansion in its custom silicon business.

Lam Research appears positioned to capture additional market share across both memory and logic semiconductor segments. BofA’s approach centered on identifying immediate catalysts rather than relying solely on extended-term projections.

The investment bank simultaneously increased its AI data center spending forecast. The revised projection anticipates the market will reach $2.2 trillion by 2030, representing an upward adjustment from the previous $1.8 trillion estimate.

This translates to approximately 40% compound annual growth. BofA attributes this acceleration to demand for AI agents and intensifying competition among artificial intelligence laboratories.

The firm suggested that either a deceleration in AI advancement or implementation of new regulatory frameworks would likely expand computing requirements rather than reduce them. Aggregate spending from leading U.S. and Chinese cloud providers is projected to approach $1 trillion in the current year.

This figure could climb to $1.4 trillion by 2027. Looking further ahead, BofA estimates spending could span $2 trillion to $3 trillion by 2030.

Notwithstanding these elevated spending projections, BofA maintains that chip stock valuations remain attractive. The SOX semiconductor benchmark trades at 21 times forward earnings, sitting 12% below its median multiple since ChatGPT’s November 2022 launch.

The ‘AI Put’ Emerges as Primary Market Risk

In a companion research piece, BofA strategists identified a distinct concern. They contend the primary threat facing U.S. equities isn’t climbing bond yields.

Rather, the critical risk involves a potential erosion of investor conviction in artificial intelligence. BofA labels this phenomenon the “AI put,” adapting terminology from the established concept of a “Fed put.”

The strategists referenced recent market dynamics to substantiate this thesis. From August 31 forward, the top 20 S&P 500 performers accumulated approximately $1.7 trillion in market capitalization.

Conversely, the remaining 480 index constituents collectively shed roughly $1.9 trillion. Small-cap and mid-cap equities have weakened as bond yields touched levels unseen in decades.

Financial and utility sectors have experienced selling pressure. The Dow Jones Industrial Average, carrying lighter AI representation compared to the S&P 500 or Nasdaq, has similarly underperformed.

BofA highlighted a crucial distinction separating the AI put from the Fed put. The Fed put hinges on decisions from a single central authority, whereas the AI put relies on sentiment among countless individual market participants.

Data center construction has absorbed more than $1 trillion since late 2022, according to Goldman Sachs calculations. Equity analysts covering technology firms anticipate substantial cash flow expansion by 2028.

Analysts monitoring sectors that would ultimately purchase AI services express more measured expectations regarding that timeframe. BofA acknowledged that rising yields eventually would pressure equities.

However, the bank believes this inflection point sits higher than current market consensus suggests. Should AI confidence deteriorate while yields continue ascending, BofA warned this dual headwind could amplify losses throughout financial markets.
