Semiconductors Stocks It has officially entered a bear market after the PHLX Semiconductor Index (SOX) fell more than 20% from its record high in June 2026, raising concerns that the AI-led rally could lose momentum.
The benchmark chip index peaked at 14,655 points in late June before falling to about 11,674 by July 17, according to market data.
This decline has wiped out an estimated $3.3 trillion in market value across the global semiconductor sector and represents one of the steepest reversals in the world. Technology stocks this year.
The semiconductor sector’s bear market follows months of extraordinary gains fueled by optimism surrounding AI infrastructure spending.
Investors raised valuations on expectations that demand for advanced processors, AI accelerators and high-bandwidth memory will remain strong for years.
Why chip stocks are struggling
However, sentiment turned in early July Investors It is beginning to be questioned whether the massive capital expenditures associated with artificial intelligence will generate returns fast enough to justify the high valuations.
Concerns increased after reports indicated a slowdown in expansion plans for high-bandwidth memory production, especially among major suppliers such as SK Hynix.
The developments have raised concerns that supply growth may outpace actual demand from AI data center operators.
Meanwhile, the Federal Reserve’s more hawkish stance has lowered expectations for near-term interest rate cuts, adding pressure on growth-focused technology stocks.
The recent sell-off in chip stocks has sparked debate about whether parts of the AI market have entered bubble territory.
A major catalyst has come from China, where the launch of a large open source AI prototype has raised questions about the long-term need for expensive proprietary hardware.
Hyperscalers spend
Investors are beginning to reevaluate assumptions that high-volume technology companies will continue to spend hundreds of billions of dollars annually on specialized AI chips.
Memory-related semiconductor companies were among the hardest hit. Stocks related to Micron (NASDAQ: in), Samsung Electronics and SK Hynix saw significant declines, contributing to broader weakness across global chip markets.
Although Nvidia (Nasdaq: NVDA) Showing greater resilience than many of its peers, the broader semiconductor industry has struggled as investors turn away from highly valued names associated with artificial intelligence.
The upcoming earnings season is expected to be the next major test for the sector.
Investors will be watching guidance from major chipmakers for evidence that demand for AI remains strong. Any signs of slowing orders, delayed deployments or weaker spending plans could lead to further volatility.
Despite entering bear market territory, semiconductor stocks remain well above levels seen before the AI boom accelerated.
The sector continues to benefit from long-term demand for advanced computing power and AI infrastructure.
