Story HighlightsNasdaq Composite dropped 2.86% on October 30, recording its steepest single-day decline since June.
Rising AI infrastructure costs, earnings disappointments and concerns over future returns have intensified selling across technology stocks.
The index is approaching its 200-day exponential moving average (EMA), putting a key long-term support level in focus.
The technology rally that powered Wall Street for much of 2026 is facing a serious test. The Nasdaq Composite fell 2.86% on Friday, extending its October decline as investors reassessed the costs and potential returns of the artificial intelligence boom. The pressure has spread from mega-cap technology companies to semiconductor stocks, with some of the market’s biggest AI beneficiaries suffering sharp losses. Now, with the index trading closer to its 200-day exponential moving average (EMA), investors face two questions: Is this a temporary correction in the tech rally, or the beginning of a deeper market reset?

The latest decline reflects more than disappointing quarterly results. Investors are increasingly questioning whether the enormous investments in AI infrastructure can generate returns quickly enough to justify current valuations.
1. AI spending is becoming a market concern
Alphabet, Amazon and Meta have signalled further increases in spending as they expand data centres, computing capacity and AI infrastructure. However, the scale of these commitments is raising questions about capital efficiency, cash flow and the timeline for monetisation.
More than $2 trillion in market value was at risk of being erased from the Nasdaq-100 during October as investors reassessed the economics of the AI buildout. Rising reliance on debt financing has added another layer of concern.
2. Earnings are failing to justify elevated expectations
Amazon’s rising capital expenditure and cash outflow intensified concerns about the cost of its AI expansion. Intel delivered another blow after its outlook disappointed investors, sending its shares down 28.6% on Friday.
The selling extended across semiconductor stocks. Nvidia declined 4.2%, AMD dropped 10.9%, and the semiconductor index lost 7.2%. These moves show how quickly pressure on individual companies can spread across the wider technology sector.
3. Investors are reconsidering technology valuations
After a prolonged rally, expectations for major technology companies had become demanding. Even companies reporting strong revenue growth are facing scrutiny over how much they must spend to sustain that growth.
The market is no longer rewarding AI exposure alone. Investors increasingly want evidence that infrastructure spending is translating into stronger earnings and sustainable free cash flow.
