Tech Sector’s Volatility Reshapes U.S. Stock Market Dynamics
The recent fluctuation in shares associated with artificial intelligence (AI) serves as a poignant reminder of the burgeoning influence the technology sector wields over the U.S. stock market.
This week, the S&P 500 and Nasdaq Composite faced their most significant one-day declines in nearly a month, primarily driven by a notable downturn in tech stocks.
While the indexes showed some recovery on Wednesday, the technology sector continued to slightly shed value.
Having enjoyed an extended period of robust performance, technology constitutes the largest sector in the S&P 500, representing approximately 36% of the benchmark index—a proportion exceeding that observed during the dot-com era a quarter-century ago, as noted by Howard Silverblatt, senior index analyst at S&P Dow Jones Indices.
Including major corporations not explicitly classified as tech—such as Google’s parent Alphabet, Amazon, Tesla, and Meta Platforms—the cumulative weight of these entities approaches 50% of the S&P 500.
Given the immense reliance on AI prospects, this concentration in major indexes renders the broader market particularly vulnerable to adverse developments, investors caution.
“A significant proportion of the S&P is tethered to one singular sector and theme,” remarked Walter Todd, chief investment officer at Greenwood Capital in South Carolina.
“Any misstep concerning AI introduces risks not only to individual companies but also to the market as a whole.”
The technology sector has experienced a decline of over 3% since last week, with notable weaknesses observed in prominent stocks such as Palantir Technologies and Nvidia, both of which have been flagship equities in the AI trade.
Investors speculate that the tech shares may have been primed for a pause following a vigorous ascent, positing that such a retracement could serve as a constructive reset conducive to future gains.
Conversely, with much of Wall Street vigilant to signs of an “AI bubble,” any weakness is facing scrutiny for indications of potentially more severe downturns.
The CEOs of Morgan Stanley and Goldman Sachs expressed concerns on Tuesday, warning that equity markets might be poised for a drawdown, emphasizing apprehensions regarding inflated equity valuations.
Currently, the S&P 500’s forward price-to-earnings ratio stands at approximately 23 times, surpassing its 10-year average of 18.8, according to LSEG Datastream. The tech sector’s forward P/E ratio of about 32 times also notably exceeds its 10-year average of 22.2.
The unparalleled performance of the tech sector has been a hallmark of the ongoing bull market, which has recently surpassed three years in duration. During this period, the S&P 500 has surged by 90%, while the technology sector has soared by an astonishing 186%.
Despite its recent downturn, technology remains the top-performing sector among the 11 that comprise the S&P 500 year-to-date, with a rise of approximately 27% against an over 15% gain for the broader S&P 500, which remains close to record highs.
This remarkable outperformance has resulted in an increase in tech’s weighting within the S&P 500 from just under 33% at the year’s onset to the current approximation of 36%. The subsequent largest sector, financials, has a weight of just 13%.
“A sustained downturn in tech stocks will invariably pull down the indexes,” stated Matt Maley, chief market strategist at Miller Tabak.
Robust profits from the tech sector have underpinned the increases of these stocks and their considerable index weightings.
Projections indicate that tech will account for almost 25% of the aggregate S&P 500 earnings in the third quarter, according to Tajinder Dhillon, head of earnings research at LSEG.
Many investors assert that the tech firms spearheading the AI narrative are financially more resilient than many entities from the internet’s inception 25 years ago.
“The companies at the forefront of monetizing AI are substantial enterprises with robust cash flows,” asserted Scott Wren, senior global market strategist at Wells Fargo Investment Institute.
Wren further noted that the capacity of large tech companies to sustain impressive capital expenditures related to AI is a pivotal driver of the stock market.
“If there’s even a hint that these investments won’t yield results, markets will react swiftly and unfavorably,” Wren cautioned.
