The first trading session following the National Day holiday on October 8 brought a rough open for the A-share market.
All three major indices closed lower, with the ChiNext Index plunging 3.15% and the STAR 50 Index tumbling 4.82%, while more than 3,700 individual stocks declined and turnover swelled to 1.69 trillion yuan.
Technology and growth sectors bore the brunt of the selling, with optical communications and the semiconductor supply chain leading losses, while oil and gas, shipping, banking, and utilities bucked the trend, highlighting a clear rotation from crowded high-flying names into defensive and resource plays.
After the close, a number of public fund managers and prominent market commentators quickly weighed in on the unusual move.
Broadly speaking, institutions characterized the day's decline as a short-term convergence of three forces: tightening expectations for overseas liquidity, disruptive industry news, and an internal rebalancing of positioning, rather than a fundamental reversal in domestic economic fundamentals or market trajectory.
Tracing the selloff: global long-end rate shock meets rumor mill
An overnight "double whammy" in global stocks and bonds was the primary external trigger for the day's correction.
Li Xuewei, fund manager at HSBC Jintrust Fund, noted that the U.S. 10-year Treasury yield broke through 5.3% again, at one point climbing to 5.36%, the highest since 2002, while the U.S. Treasury Department completed a 10-year note auction on October 7 at a yield of 5.3%, the highest since November 2000.
At the same time, minutes from the Federal Reserve's September meeting showed most officials believed another rate hike could still be needed this year, and specifically flagged that artificial intelligence infrastructure buildout could add upward pressure on inflation.
"The hawkish signals directly suppressed globally high-valued growth stocks, transmitting negative sentiment to the A-share market," Jinxin Fund said in its commentary.
At the industry level, the disruption amplified the decline in technology names.
Morgan Stanley published a research note during the holiday period speculating that the U.S. Federal Communications Commission could set a U.S. content threshold for optical modules, with restrictions potentially starting from the next-generation 3.2T high-speed optical modules.
Yang Delong, chief economist at Qianhai Open Source Fund, pointed out that the report had no supporting official U.S. document and was merely an analyst's personal extrapolation based on automotive industry rules, but "the market impact was obvious."
Jinxin Fund added that Morgan Stanley's October 1 note judged the relevant restrictions were most likely to land in the 3.2T generation, making optical chip stocks the hardest-hit area in the day's selloff.
The fragility of internal positioning was the domestic cause.
Both Jinying Fund and Jinxin Fund noted that the technology主线 had posted enormous gains earlier and trading had become crowded, with profit-taking pressure released in concentrated fashion.
The STAR 50 Index hit an intraday low not seen since April 29, having retreated more than 35% from its July peak, as capital accelerated its rotation from elevated tech names into lower-positioned sectors such as banking, oil and gas, and batteries, further magnifying selling pressure.
Fund flows reveal the truth: not a systemic risk
What the market displayed was not an across-the-board rout, but a sharp structural rotation.
Sectors including oil and petrochemicals, utilities, transportation, coal, and banking closed higher against the tide, with the petrochemical sector gaining 2.46%.
Li Xuewei of HSBC Jintrust interpreted this as follows: "The fact that dividend and resource sectors rose against the trend during this pullback shows the market is not releasing systemic risk, but rather rebalancing highly crowded technology positions and rotating capital toward low-valuation defensive areas."
One detail worth noting is that the central bank conducted 1.2 trillion yuan of outright reverse repurchase operations on the day, a clear signal of liquidity support.
Jinxin Fund concluded on this basis that "this round of adjustment is more a correction of the trading structure in elevated sectors, not a reversal of the industry trend."
The overseas AI industry trend itself has not reversed either.
HSBC Jintrust pointed out that during the holiday period the Nasdaq and S&P 500 briefly hit record highs and the Philadelphia Semiconductor Index rose against the trend, with the A-share tech pullback stemming more from positioning and sentiment.
Institutions diagnose the outlook: patience for confidence to recover, balanced allocation becomes consensus
For fourth-quarter trends, institutional views differ in emphasis but share a consensus that "the slow bull is not over and the market is consolidating for a move."
Yang Delong's judgment was fairly direct: "The A-share market remains in a weak adjustment... but one cannot conclude that this slow bull run in A-shares has ended."
He believes a repeat of the sharp technology rally seen in the first half is unlikely, and that "structural opportunities will dominate," with beaten-down quality stocks or quality funds still offering allocation value in a fourth-quarter rebound.
Jinying Fund offered a positive signal from a pricing perspective: "Looking back at A-share history, if the market fell in the 5-10 trading days before a holiday, the probability of gains after the holiday tends to be higher."
The institution argued that the market has already priced in many negatives such as geopolitics, oil prices, and high interest rates, and that as uncertainties resolve and third-quarter earnings expectations approach, "a new repair and phased rebound window could form."
On allocation, it recommends continuing a "barbell strategy": on one end, focus on core technology names with strong third-quarter earnings certainty such as optical communications, PCB, and semiconductor equipment; on the other end, focus on high-dividend, low-valuation directions such as oil and gas, coal, and shipping.
HSBC Jintrust offered a more systematic medium- to long-term outlook.
Li Xuewei said domestic equity assets have ample room, and with the "anti-involution" policy and coordinated fiscal and monetary support, corporate earnings and ROE are in a recovery cycle, positioning A-shares for medium- to long-term support driven by both the numerator (earnings improvement) and the denominator (domestic liquidity support).
He highlighted three directions: midstream manufacturing and consumption sectors benefiting from economic stabilization and supply-demand improvement, high-dividend plays with defensive value, and technology growth opportunities that still show momentum after being validated by earnings delivery.
Jinxin Fund specifically flagged the key window represented by third-quarter reports: "October enters the密集 disclosure period for third-quarter earnings, and the ability to deliver on results will become the core anchor for pricing technology stocks, with segment leaders that have genuine profit support expected to stabilize first."
Taking institutional views together, the day's sharp decline looks more like a "technical clearing" ignited by an external rate shock and industry rumors, and fueled by crowded internal positioning.
Once the market recovers from panic, earnings certainty will once again become the anchor for pricing.
As Yang Delong put it: "Patiently wait for the next rebound to arrive."
