Tech, chip stock sell-off continues as AI bubble fears mount
Among the Magnificent Seven Big Tech stocks, Nvidia (NVDA) was down about 0.8%, and Alphabet (GOOGL, GOOG) stock fell about 0.6%. Amazon (AMZN), Apple (AAPL), and Meta (META) shares fell over 1%.
Chip stocks Advanced Micro Devices (AMD) and Broadcom (AVGO) dropped more than 2%; Micron (MU) shares plummeted more than 5%.
CoreWeave (CRWV), the AI data center company that rents computing power to Microsoft (MSFT) and Meta — making it essentially an AI pure play — also dropped nearly 4%.
Palantir (PLTR), a defense tech stock that's seen a major upswing from the AI boom, sank nearly 2%, extending its recent losing streak.
The rotation out of AI-linked stocks comes as sentiment soured this week on the market for artificial intelligence, fueled in part by a recent report from the Massachusetts Institute of Technology and commentary from OpenAI CEO Sam Altman.
Researchers for MIT's Project NANDA authored a report released this week that said 95% of companies it studied are getting no return on AI. The findings of the report were first detailed by Fortune on Monday.
That report followed commentary from OpenAI's Altman shortly after the ChatGPT-maker finished out its latest multibillion-dollar funding round, with the CEO telling reporters that he believes there's an AI bubble, a diversion from his prior characterizations.
'When bubbles happen, smart people get overexcited about a kernel of truth,' he said. 'Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes."
DA Davidson analyst Gil Luria likened the changing market sentiment to a pendulum.
'This is really just pendulum swinging back,' he told Yahoo Finance on Wednesday.
AI stocks have taken off in recent months after a rocky start to the year. A new, cost-effective AI model from Chinese firm DeepSeek released in January cast doubt on the massive sums of money Big Tech was spending to build out AI infrastructure to power the technology — and sent tech stocks tumbling.
Two rounds of earnings updates from some of the biggest AI plays in the market and more clarity on Trump's trade policies have since quelled those fears.
Investors applauded recent quarterly reports from Big Tech firms Alphabet, Meta, and Amazon, which surpassed Wall Street's expectations as the companies said AI boosted their underlying businesses. That news overrode the fact that those companies also raised their forecasts for spending on AI infrastructure.
'The AI trade was getting so expensive that all it took was some comment from Sam Altman to make the investment community take some profits off the table,' Luria said.
Luria added that 'the reality is that AI still has limited applications' beyond consumers talking to AI chatbots and using the tools as a search engine.
Some AI bulls, however, maintain faith in the technology's ability to fuel markets to new highs.
'We are still in the early days of the AI Revolution as the use cases are just starting to massively expand as more companies recognize the value creation being driven by a handful of tech companies led by the Godfather of AI [Nvidia CEO] Jensen [Huang] and Nvidia,' wrote Wedbush analyst Dan Ives in a note to investors Wednesday.
He added that 'the tech bull cycle will be well intact at least for another 2-3 years given the trillions being spent on AI.'
More will be revealed when leading AI chipmaker Nvidia reports its quarterly earnings results after the bell next week on Aug. 27.

Goldman Traders Say It's Time to Buy the Dip in Momentum Stocks
(Bloomberg) -- Sharp losses in high-flying momentum stocks may present a dip-buying opportunity if history is any guide, according to Goldman Sachs Group Inc.'s trading desk. The traders cited rebounds after similar prior losses in Goldman's High Beta Momentum basket, coupled with the current technical setup. Why New York City Has a Fleet of New EVs From a Dead Carmaker Trump Takes Second Swing at Cutting Housing Assistance for Immigrants Chicago Schools Seeks $1 Billion of Short-Term Debt as Cash Gone Neom's Desert Ski Resort Strains Saudi Prince's $1.5 Trillion Plan When the long-short momentum basket dropped 10% or more over a five-day span in the past, it proceeded to rise in the following week 80% of the time, the traders wrote in a note to clients on Tuesday. The median return was 4.5% in the next week and more than 11% in the next month. The sudden unwind in the momentum strategy, which focuses on buying recent winners and selling short those that are lagging behind, first came amid a rally in the basket's stocks meant to be shorted. But its declines this week were powered more by losses in the long leg of the basket 'as themes such as AI feel the pain of this rotation,' Goldman's traders wrote. The basket fell 13% from Aug. 6 through Aug. 19 after trading near an all-time high. The traders also parsed through technical charts for clues on what could stop the selloff in the momentum trade. The momentum basket is trading near an oversold territory and is approaching the bottom of its so-called regression channel, which is basically the lower boundary of an existing trend. The basket also fell below its 200-day moving average, the level that could serve as a major support. 'It could be a good entry point into the historically rewarded factor, unless tech earnings next week drive a prolonged AI selloff,' Goldman's traders wrote. Nvidia Corp., the biggest member in both the S&P 500 and Nasdaq 100 indexes, is scheduled to release its quarterly results on Aug. 27. Some of the stock market's biggest losers in the past three days include Palantir Technologies Inc., which fell 12%, and Advanced Micro Devices Inc. and Super Micro Computer Inc., which lost 6% or more. Nvidia fell just 2.8% during that time, but its heavy weighting in benchmark indexes made it a drag on the market. Those stocks 'were among the year's most crowded trades, built on optimism toward AI and speculative momentum, making them vulnerable to swift reversals,' Chris Murphy, co-head of derivatives strategy at Susquehanna International Group, wrote in a note. The selloff in the momentum factor, which includes high-flying AI stocks on the long side of the basket, comes amid a variety of concerns in the market including soaring valuations, stretched positioning and increasing competition from China. The Nasdaq 100 Index is trading at 27 times expected 12-month profits, almost a third above its long-term average. Meanwhile, China's warnings to tech firms to avoid one of Nvidia's chips and a drop in cloud-computing company CoreWeave Inc.'s shares after its earnings report were among other recent headwinds to momentum stocks. Another source of concern for tech investors cropped up this week as a Massachusetts Institute of Technology report found that most generative AI initiatives implemented to drive revenue growth are falling flat and only 5% of generative AI pilots are delivering profit. Still, this isn't the only stumble for Goldman's High-Beta Momentum basket this year: This is its fourth retreat of more than 10% in 2025. 'The recent decline in momentum is indicative of how the factor has been trading all year. It's been a frustrating and choppy trade through all of 2025,' said Bloomberg Intelligence's Christopher Cain. 'While the recent decline could be a tactical opportunity, we also point out that that high momentum stocks are showing some of the most expensive valuations compared to low momentum in history.'

3 Small-Cap Stocks We Think Twice About
Small-cap stocks can be incredibly lucrative investments because their lack of analyst coverage leads to frequent mispricings. However, these businesses (and their stock prices) often stay small because their subscale operations make it harder to expand their competitive moats. These trade-offs can cause headaches for even the most seasoned professionals, which is why we started StockStory - to help you separate the good companies from the bad. Keeping that in mind, here are three small-cap stocks to avoid and some other investments you should consider instead. (CARS) Market Cap: $740.4 million Originally started as a joint venture between several media companies including The Washington Post and The New York Times, (NYSE:CARS) is a digital marketplace that connects new and used car buyers and sellers. Why Does CARS Fall Short? Market opportunities are plateauing as its dealer customers were flat over the last two years Estimated sales growth of 2% for the next 12 months implies demand will slow from its three-year trend Falling earnings per share over the last three years has some investors worried as stock prices ultimately follow EPS over the long term At $12.05 per share, trades at 3.5x forward EV/EBITDA. Read our free research report to see why you should think twice about including CARS in your portfolio, it's free. Matthews (MATW) Market Cap: $724.2 million Originally a death care company, Matthews International (NASDAQ:MATW) is a diversified company offering ceremonial services, brand solutions and industrial technologies. Why Are We Out on MATW? Annual sales declines of 6.5% for the past two years show its products and services struggled to connect with the market Earnings per share fell by 14.8% annually over the last five years while its revenue grew, showing its incremental sales were much less profitable Cash-burning tendencies make us wonder if it can sustainably generate shareholder value Matthews's stock price of $23.52 implies a valuation ratio of 15.4x forward EV-to-EBITDA. Dive into our free research report to see why there are better opportunities than MATW. CTS (CTS) Market Cap: $1.22 billion With roots dating back to 1896 and a global manufacturing footprint, CTS (NYSE:CTS) designs and manufactures sensors, connectivity components, and actuators for aerospace, defense, industrial, medical, and transportation markets. Why Do We Think Twice About CTS? Annual sales declines of 5.7% for the past two years show its products and services struggled to connect with the market during this cycle Revenue base of $520.9 million puts it at a disadvantage compared to larger competitors exhibiting economies of scale Earnings per share have dipped by 4.5% annually over the past two years, which is concerning because stock prices follow EPS over the long term CTS is trading at $41.55 per share, or 17.3x forward P/E. Check out our free in-depth research report to learn more about why CTS doesn't pass our bar.
