American chip stocks have stumbled out of the gate in July, and market watchers say more turbulence could be on the way as investors grapple with lofty valuations and growing uncertainty about how long the artificial intelligence spending boom will last.
The Philadelphia Semiconductor index has dropped more than 11% since reaching a record peak in June. Despite that slide, the index remains up 83% for the year — a figure that hangs over every conversation about the sector’s future. These companies have benefited enormously from rising prices and supply-demand imbalances, but financial markets are always looking ahead.
Steve Sosnick, chief market analyst at Interactive Brokers, put it plainly: “We’ve never seen this kind of extreme earnings growth. But the question then becomes, how long can we expect this to continue.”
Money Flowing Out
Funds that track U.S. semiconductor stocks saw outflows of roughly $11 billion during the week ending June 24 — the largest weekly exodus of money from the sector this century, according to LSEG Lipper data. That followed two weeks in which those same funds had pulled in about $12 billion in fresh investment, underscoring just how volatile sentiment has become.
Analysts broadly expect that major technology companies will keep spending heavily on cloud and AI infrastructure. A note from BofA Securities this week projected that global cloud and AI infrastructure capital expenditure could approach $1.5 trillion by 2027, representing a 40% to 50% jump year over year. Much of the current anxiety, analysts say, is driven by hypothetical scenarios — what happens if stock prices fall or companies start cutting their capital spending plans.
Wall Street Still Bullish
Despite the recent dip, U.S. brokerages have been raising their price targets for chip stocks, fueled by expectations that demand for AI technology will keep supporting earnings growth.
Among S&P 500 chipmakers, Micron has the highest projected upside relative to its current price — more than 60% — based on the consensus analyst target, according to LSEG data. Memory chipmaker Sandisk’s shares are seen rising more than 30%. Nvidia’s stock is expected to climb over 40%.
SK Hynix, another memory chip company, jumped more than 10% in its U.S. trading debut on Friday after a $26.5 billion share sale, buoyed by soaring memory prices driven by tight supplies.
However, several other large semiconductor firms are already trading near their median 12-month price targets, suggesting that much of the expected gain may already be reflected in current prices.
Alexander Lis, chief investment officer at SD Ventures, offered a note of caution: “I consider elevated price targets to be rather a consequence of the incredible momentum in semis rather than a reliable indicator of future performance.”
Short Sellers Returning
Data analytics firm ORTEX reports that bets against major semiconductor companies have been building over the past year, with short interest now sitting at a three-year high.
Peter Hillerberg, co-founder at ORTEX, described the trend this way: “This is caution and hedging creeping back into the sector after a huge run, not the kind of crowded, high-conviction shorting that leads to squeezes.”
Hillerberg added that short interest in these stocks has nearly doubled on average over the past three years, with the biggest increases seen in Marvell, Qualcomm, and Micron.
Earnings Under the Microscope
Earnings for companies on the S&P 1500 Semiconductors & Equipment Industry index are expected to more than double this year, driven largely by Micron and Nvidia, according to data compiled by LSEG. But that growth is projected to slow in 2027, with profits expected to rise 46.1%.
Adding to the uncertainty, the unclear path for U.S. interest rates and ongoing conflict in the Middle East could weigh on future earnings estimates.
The Valuation Question
Nvidia, which has been central to the AI-driven market rally, is currently trading at a forward price-to-earnings ratio of about 19 — its lowest level in more than a decade. Micron’s forward P/E touched a nine-year low of 5.4 back in May.
Chris Maxey, chief market strategist at Wealthspire Advisors, explained: “The valuations have gotten cheaper over the last two years, and that’s primarily a function of earnings growing faster than the price.”
Still, forward P/E ratios for Intel, Advanced Micro Devices, and Marvell Technology remain well above their long-term averages, suggesting that earnings expectations haven’t caught up quickly enough — and potentially turning investor attention back toward the cyclical, commodity-like nature of the chip business, especially in memory chips.
Marija Veitmane, head of equity research at State Street Global Markets, summed up the long-term outlook: “It’s impossible to argue that the cyclicality of the sector will go away. I think the cycle will just get a lot longer.”
