Nasdaq’s toughest month in over a year as AI jitters shake markets

Live Global Market

Wall Street experienced significant losses on Friday, as the most recent tech earnings rekindled worries that substantial investments in AI may not yield the anticipated returns for investors. The Nasdaq Composite experienced a decline of 2.86%, while the S&P 500 saw a decrease of 1.82%, marking their most significant downturn since June. The Dow experienced a decline of 572 points, equating to approximately 1.1%. Just a few weeks ago, the Nasdaq and S&P 500 reached unprecedented levels. However, markets experienced turbulence this month due to escalating concerns regarding elevated interest rates, substantial cash expenditures by tech companies on extensive AI investments, and earnings and forecasts that fell short of expectations. The Nasdaq is currently down 7.8% from its record high earlier this month, experiencing its most significant monthly decline since March 2025. The S&P 500 has experienced a decline of approximately 3% from its recent peak. Intel experienced a significant decline of 28.58% on Friday, marking its most substantial drop since 1974 and the second-largest in its history. This downturn followed the company’s announcement of weaker guidance for the fourth quarter, attributing the challenges to a downturn in the PC market, where elevated memory chip costs are adversely affecting consumer demand.

Amazon shares experienced a decline of 1.4% after the release of an earnings report that revealed a continued rise in AI expenditures, alongside sales and profit figures that fell short of analysts’ forecasts. This follows a decline in shares of Alphabet – the parent company of Google – which fell by over 12% on Thursday, resulting in a loss of half a trillion dollars in market value for America’s fourth-largest company. Investors expressed apprehension regarding a deceleration in Google’s search advertising sector alongside an increase in expenditures related to artificial intelligence. Alphabet shares declined by an additional 1.4% on Friday, concluding what has been their most challenging month historically. Investors’ apprehensions regarding the AI surge have unsettled other semiconductor manufacturers: Nvidia’s shares declined by 4.2%, whereas a key index of chipmakers fell by 7.2%. Alphabet, Microsoft, Meta, and Amazon are collectively investing hundreds of billions of dollars in the construction of data centers. After enthusiastically supporting all things AI, Wall Street is becoming increasingly selective regarding which companies are allocating resources judiciously and achieving measurable returns on investment.

Friday marked the conclusion of a challenging month for AI stocks, as investors remain vigilant regarding the substantial expenses associated with the AI surge and seek tangible proof that these investments will ultimately yield profits. “We’re moving out of the hopes and dreams phase of the AI trade and into the ‘show me’ phase,” Joe Tigay said in a note. “Full order books are great, but investors want to see who can actually deliver, turn that demand into earnings and generate cash,” he said. Alphabet’s earnings results on Wednesday sparked apprehensions regarding the potential jeopardy facing Google’s primary revenue stream from search advertising, as consumers increasingly turn to AI chatbots in lieu of conventional search methods. Alphabet’s promise of returns from AI “is getting pushed even further down the road,” Matt Maley said in a note. “It raises the question as to whether the payout will be as big as they have been promising.”

As major technology companies increase their expenditures, investors are expressing concerns regarding the potential effects on their financial statements. Alphabet has reported two consecutive quarters of negative free cash flow for the first time in its history, attributed to the rapid increase in AI expenditures, while revenue growth has not met expectations. Meta last week reported a quarter of negative free cash flow for the first time since 2012. Amazon on Thursday reported a negative free cash flow of $42.4 billion over the past 12 months as the company increases its investments in AI. “Investors don’t just want capex, they want to see the returns already,” Neil Wilson said in a note. “For the wider AI trade, we are starting to see a more critical evaluation of the return on investment from this monster AI splurge.” Alphabet and Meta are currently experiencing a bear market, having declined over 20% from their respective peaks in May and August 2025. In contrast to Alphabet, Meta, and Amazon, Microsoft reported $18.6 billion in positive free cash flow for the past quarter, with its stock experiencing a modest decline of only 4% since reaching a record high earlier this month.

Investors are increasingly highlighting the competition among companies to secure capital through debt and equity markets, viewing this as an indication that the AI boom is transitioning into a new phase. Elevated interest rates are exerting pressure on the more speculative, debt-driven segments of the AI development landscape, contributing to growing unease. Anthropic’s highly anticipated filing for its initial public offering on Monday provided a momentary uplift to tech stocks, but the sentiment shifted negatively by midweek in response to Big Tech earnings. “The AI trade is down, but not out,” said Paul Stanley in a note Friday morning. “This is not the first tech and AI correction, and it won’t be the last. We are still in the very early stages of AI development, and pullbacks are par for the course.” Adding to market jitters Friday: Bitcoin fell more than 4% over the past day, hitting its lowest level in more than a month, after the world’s largest crypto exchange was struck by the largest heist on record. Following a significant rally this year, investor expectations for chipmakers are on the rise, while companies find it challenging to meet Wall Street’s demands.

Despite a significant decline of nearly a third in value on Friday, Intel shares have nonetheless appreciated by 78% year-to-date. “A lot of these names, Intel is no exception, they just had a phenomenal year already. So, there’s definitely some profit taking as a result,” said Mike Dickson. As investors divested from technology equities, they shifted their focus toward more defensive segments of the market, such as the consumer staples sector and government bonds. Other sectors of the technology industry have also experienced turbulence as investors closely examine earnings and seek proof that companies will gain from, rather than be jeopardised by, advancements in artificial intelligence. Shares of software company ServiceNow experienced a significant decline of 27% on Thursday, marking the most severe drop in its history, following the company’s profit results that fell short of Wall Street’s expectations. ServiceNow experienced a decline of 4% on Friday. “The market doesn’t like uncertainty,” said Ted Mortonson. “People just get out of the way until they can figure it out.”
