China’s semiconductor equities suffered one of their sharpest single-session routs of 2026 on Friday, as retail-driven exuberance ran headlong into a wall of macroeconomic anxiety, and even coordinated buying by two of Beijing’s largest state investment vehicles failed to steady the market. The selloff has punctured, at least temporarily, the narrative that Chinese chipmakers had entered a durable bull market underwritten by import substitution and Washington’s export controls.
According to a detailed market analysis published by Asia Times, Hua Hong Grace Semiconductor plunged 12.58% on the day, Beijing YanDong Micro dropped 10.55%, Ningbo Silicon Electronics fell 9.44%, and Shenzhen Intellifusion shed 9.42%. Semiconductor Manufacturing International Corp. (SMIC), long treated as the flagship of China’s foundry ambitions, closed down 2.95%, a comparatively mild decline that nevertheless erased tens of billions of yuan in market value given the company’s size.
The scale of the drawdown is significant not because Chinese chip stocks are unfamiliar with volatility, but because Beijing’s rescue apparatus visibly engaged and visibly failed to hold the line.
State Funds Deployed, Market Kept Falling
Two of China’s most powerful arms of its state investor toolkit entered the market on Friday. China Reform Holdings drew on the People’s Bank of China’s stock market relending facility, deploying roughly 50 billion yuan ($7 billion) to support strategic equities. China Chengtong, another central state-owned enterprise operating as a national-team investor, purchased approximately 10 billion yuan of domestic stocks over the session.
In prior episodes of market stress, most notably during the 2015 and early 2024 panics, the mere signal of national-team involvement has been enough to reverse intraday declines. Not this time. The buying absorbed some of the pressure, but could not prevent double-digit percentage losses in the most inflated names. For a leadership team that has spent the past three years pouring political and financial capital into semiconductor self-sufficiency, the optics of a failed defense are uncomfortable.
Valuations That Even Bulls Struggle to Justify
The proximate cause of the selloff, according to Asia Times, is straightforward: Chinese chip stocks have simply outrun any semblance of fundamental support. The top 11 A-share semiconductor companies now carry a combined market capitalization of 7.37 trillion yuan against projected 2026 combined net profits of only 60.4 billion yuan — an average price-to-earnings ratio of roughly 122 times.
Individual names look even more extreme. Moore Threads, the GPU designer positioning itself as a domestic alternative to Nvidia, trades at a P/E multiple of approximately 2,560. Hua Hong Grace sits at 1,039 times earnings. By comparison, Nvidia, the company whose data-center dominance has driven the global AI capex cycle, trades at a trailing P/E of roughly 32.5. In other words, several Chinese chipmakers are trading at 30 to 80 times the multiple of the world’s most profitable AI infrastructure company, while generating a small fraction of that company’s cash flow.
The rally that produced these multiples has been extraordinary in its own right. Cambricon Technologies, the AI accelerator designer, has risen roughly 643% over the past two years. SMIC is up 321% over the same period. Much of that appreciation has been driven by a policy narrative — that US chip sanctions guarantee a captive domestic market, rather than by realized earnings growth. Domestic revenue substitution is real, but it has not scaled at anywhere near the pace implied by current share prices, particularly for firms still years away from producing leading-edge nodes at commercial volume.
Three Triggers Converge
The Asia Times report identifies three distinct triggers that combined to break market psychology in the second half of July.
The first was the Bank of Korea’s surprise rate hike on July 16, which tightened liquidity conditions across Asia and pressured all rate-sensitive growth assets. The second was the release of the US Federal Reserve’s July 17 meeting minutes, which struck a more hawkish tone on the trajectory of American policy rates than markets had been positioned for. Together, those two events reset the discount rate assumptions embedded in every high-multiple technology stock in the region.
The third and most immediate trigger came on July 21 and 22, when institutional investors began dumping semiconductor holdings ahead of earnings previews that pointed to weaker-than-expected second-quarter results at several mid-cap chipmakers. Retail investors, who had been the marginal buyers driving the rally, hesitated. With the state-team bid arriving into a market already in liquidation mode, the flows simply overwhelmed official support.
A Bubble Inside a Strategic Priority
The awkward reality confronting Chinese policymakers is that the chip sector’s overvaluation is in part a byproduct of policies they themselves designed. Beijing has spent years directing capital toward semiconductors through the “Big Fund,” provincial guidance funds, and the Hefei-style municipal investment model that has funneled money into companies such as CXMT, which is preparing an $8.6 billion Shanghai STAR listing on Monday. When capital allocation is subordinated to strategic priority, price discovery breaks down.
That dynamic is not confined to chips. It also underpins the ongoing IPO wave in Chinese AI, where Moonshot, DeepSeek, and MiniMax are pursuing listings at valuations that assume flawless execution over the next decade. As we noted earlier this week in our coverage of China’s AI IPO rush, the primary market has become the release valve for domestic capital with nowhere else to go. Friday’s selloff is a reminder that the secondary market is not immune to gravity, no matter how strategically important the sector.
There are also spillover risks for adjacent industries. Local government financing vehicles have plowed billions into semiconductor equity stakes, and as our recent piece on Hefei’s CXMT jackpot and the local government tech bet model explored, municipalities have increasingly relied on paper gains from chip investments to shore up their balance sheets. A sustained repricing would cascade into local finances at a moment when property-related revenues are already under pressure.
What Comes Next
For now, the question is whether Friday’s action represents a healthy correction, a shakeout of leveraged speculators, or the start of a broader repricing that forces the national team into ever-larger interventions. History suggests Beijing will not tolerate a disorderly decline in a sector it has defined as central to national security. Expect additional state fund deployments and possibly informal guidance to institutional investors to halt selling in strategic names.
But the arithmetic is unforgiving. A market capitalization of 7.37 trillion yuan cannot be indefinitely sustained on a profit base of 60.4 billion yuan, no matter how deep the state’s pockets or how urgent the geopolitical rationale. At some point, either earnings must catch up to valuations, or valuations must come down to meet earnings. Friday was a hint of which way the adjustment is more likely to run.
