Disappointing results from companies including Alphabet, Amazon, and Intel pushed the S&P 500 tech sector down 6.8 percent during October. Although nine out of 11 sectors advanced as investors rotated into non-tech equities, the tech sector's heavy weighting still poses significant systemic risks. A major concern is that any reduced infrastructure spending could cause severe ripple effects, especially since Oxford Economics estimates artificial intelligence accounts for roughly one-third of recent U.S. economic growth.

NEW YORK, Nov 2 : A steep decline in the prices of US AI and technology stocks is testing investors' enthusiasm to shift into other equity areas, a rotation that has propped up broader indexes in recent weeks.
Disappointing results from Alphabet, Amazon and Intel dealt the latest blow to the AI trade. Investors worry about the hefty financing needed to fund massive investment spending. They are also starting to question whether returns will be robust enough to justify that spending.
The broader market in October held up far better than tech- and AI-exposed equities did, but it may not be able to endure a more severe pullback in the massive AI trade. The tech sector alone accounts for a 38 per cent weight in the S&P 500.
Investors are wary of signs that the selling will spread. A main alarm would be indications that the AI hyperscalers pull back significantly on spending plans. Their investment in data centers and other infrastructure has been a key driver for overall economic growth.
Domestic equities extended their winning streak to three consecutive sessions following regulatory proposals aimed at boosting international and domestic investor participation. The broad-based rally provided crucial technical support to benchmark indices, helped by cooling global energy prices. However, market participants emphasize that durable momentum requires consistent earnings performance alongside tax relief.
Precious metal valuations retreated sharply ahead of the festive season due to global commodity pressures, rising crude oil prices, and expectations of elevated U.S. interest rates. The steep October contraction pushed both metals far below their January 2026 peaks, leaving prospective buyers weighing festive traditions against broader market risks. Analysts suggest using the downturn strategically through phased allocations rather than aggressive lump-sum entries.
Mounting skepticism across both equity and fixed-income markets is directly challenging the long-term viability of the artificial intelligence boom. This widespread hesitation has left portfolio managers evaluating whether the recent broad-based sell-off presents a genuine buying opportunity or signals deeper structural declines. The coming weeks will test investor confidence as critical economic factors continue to pressure tech valuations.
