A-share markets ended Thursday in negative territory, with major indices collectively closing lower after a choppy session. The Shanghai Composite Index slipped 1.18% to 3,888.11 points, while the Shenzhen Component Index fell 1.08%. The ChiNext Index showed relative resilience with a 0.49% decline, and the STAR 50 shed approximately 1.01%. Weakness was broad-based across both growth and value segments, with small-caps and cyclical sectors experiencing deeper pullbacks while defensive names and select hardware themes carved out divergent moves.

Within sectors, telecom equipment leaders, MLCC makers, and select defense and power-related names traded against the trend or remained relatively active. Meanwhile, industrial metals, precious metals, agricultural chemicals, diversified financials, and brokerages led declines, with nonferrous and agriculture chains bearing heavy selling pressure. Total turnover across Shanghai and Shenzhen reached approximately 1.97 trillion yuan, expanding by roughly 320 billion yuan from the previous session—a classic sign of distribution on volume.

The selling pressure stems from a twin set of headwinds. Ahead of next week's Federal Reserve meeting, stronger-than-expected nonfarm payrolls have pushed market odds of a September rate hike to around 70%, weighing directly on growth and high-valuation equities. Domestically, incremental capital remains on the sidelines with turnover staying below 2 trillion yuan for multiple sessions, forcing frequent rotation between high and low positions. With momentum exhausted, the market saw decliners vastly outnumber advancers—roughly 4,800 stocks fell against just over 600 risers—underscoring weak breadth and a cautious, range-bound digestion phase.

The primary catalyst for the risk-off tone came from overnight overseas pricing signals. The U.S. August PPI came in at 5.4% year-over-year, exceeding expectations and accelerating notably from the prior 4.7% reading. Following the data release, market odds for a September Fed hike jumped to 70%, while October hike probability rose to 82.1%. On the same day, the European Central Bank delivered a widely anticipated 25-basis-point hike across its three key policy rates, affirming the global tightening trajectory. U.S. Treasury yields surged across the curve, with the 10-year approaching 5%, while real yields climbed, directly pressuring precious metals. Brent and WTI both reclaimed the triple-digit level with amplified volatility, and gold, silver, and copper retreated in tandem as U.S. and Asian equity markets slid. Markets are simultaneously pricing energy supply shocks, sticky inflation, and upward-revised rate expectations.

The nonferrous complex has proven especially fragile because the chain has flipped from a resource-optimism narrative into a two-way squeeze in short order. While higher oil prices superficially support resource-inflation trades, rising rates and a stronger dollar immediately raise discount rates and carry costs for precious and industrial metals. Capital is shifting from cyclical offensive positions into defensive and cash-equivalent holdings at remarkable speed.

Reviewing the week, Monday marked the only growth-repair session, with the ChiNext index surging 3.41%. Telecom, computing hardware, CPO, and PCB names led gains while agriculture stayed firm, though large financials and dividend plays lagged. Turnover remained below 2 trillion yuan, indicating a structural rebound on shrinking volume. Overseas economic resilience and the stronger nonfarm payrolls supported some risk appetite, while GPT-related model upgrades and Goldman Sachs' upward revision of optical module shipment forecasts re-emphasized AI infrastructure vitality. Combined with the approaching China International Optoelectronic Exposition, the telecom equipment chain received successive catalysts.

Tuesday saw rapid style rotation as capital pivoted to agriculture and oil & gas. Soybean futures hit record highs, reinforcing the food-cycle narrative, while Middle East supply disruptions strengthened oil prices, giving petroleum-linked names price momentum. Though advancers outnumbered decliners, turnover hovered near the 2 trillion yuan edge—evidence that the market only selectively bought into names with hard price signals.

Wednesday evolved into another value-resource rebalancing. The Shanghai index edged up while ChiNext and STAR weakened. Coal, shipping ports, nonferrous metals, power, and precious metals strengthened, while media, gaming, real estate, pharmaceuticals, and baijiu retreated. Turnover contracted to roughly 1.87 trillion yuan as indices steadied on low-valuation weighted stocks, but profit-taking conditions continued to deteriorate.

Thursday remained subdued with only select defensive sectors like banking bucking the trend. Previously strong sectors such as agriculture and forestry gave back gains, main capital outflows widened, and the market clearly entered a zero-sum game of existing capital.

Overall, this week's dominant trading logic centered on oil prices and rates holding sway over overseas pricing, while domestic macros lack fresh catalysts and momentum tilts weak, leaving only persistent rotation among existing funds. High-risk appetite sectors like AI hardware and innovative drug chains remain medium-term prosperity themes, but external disruptions are forcing capital to temporarily reduce volatility exposure. Resource and dividend plays have proven mediocre ballasts in turbulent markets—some names sit at lofty levels or enter profit-taking zones, while others remain hostage to rates and the dollar.

For allocation, broad-based vehicles like the CSI A500 ETF (159338), which provides balanced coverage of industry leaders across sectors, may better suit the current rebalancing environment than betting on any single track.

Overseas markets delivered more direct signals than A-shares this week. U.S. equities entered a downtrend under the twin pressures of oil above $100 and rapidly rising Treasury yields, with capital rotating into telecom and consumer staples while semiconductors and high-beta AI infrastructure suffered. The 10-year Treasury yield climbed to around 4.95% with the 2-year also rising notably, as markets repriced the Fed's remaining tightening path for the year. A firmer dollar further drained global risk appetite. Before U.S. CPI lands and the Fed meeting concludes, it may be difficult to assume overseas risk assets return to a repair zone.

Hong Kong equities also remained weak this week, with the Hang Seng Tech Index testing prior lows. Beyond following global risk sentiment, the city's market faced an additional institutional overhang. The Ministry of Finance and State Administration of Taxation's rules on individual income tax for offshore trusts were officially issued on July 24, but the primary trigger was September 9, when the spouse of Haidilao's founder discounted share sales via a trust holding platform—the first visible case since the policy took effect. This dragged down Hong Kong-listed restaurant, beverage, and innovative drug names across the board, as markets worried about the tax implications for founder family trusts leading to further reduction and cash-out pressure. While the near-term impact is more emotional and supply-demand driven rather than fundamental deterioration, and technical support remains visible, anticipation of major shareholder reductions is amplified into liquidity discounts in an already capital-constrained environment.

The telecom sector delivered relative outperformance amid the market's repeated downside probing this week, closing as one of the few green sectors. Overnight, the FCC's final rules landed with less severity than the most bearish scenario, potentially offering a clearing of negative overhangs. The key takeaway is that restrictions mainly target equipment authorization paths containing specific logic hardware components. Chinese optical module leaders and domestic optical chip, connector, and PCB segments were not broadened into comprehensive sanctions targets, and existing authorized products do not require re-approval. The worst-case scenario previously priced in has been softened.

On the model side, the release of GPT-6 Astra continues advancing complex reasoning, coding, and agent capabilities, further reinforcing medium-term AI infrastructure prosperity expectations. On the demand front, North American cloud capex and the 1.6T/3.2T upgrade path continue to see upward revisions. Domestically, this week's Optoelectronic Expo showcased high-speed optical modules, silicon photonics, CPO, and polarization-maintaining fiber technologies. The telecom sector's fundamental narrative remains solid—near-term clearing of negative catalysts plus exhibition momentum, medium-term multiplicative demand from compute clusters for interconnect bandwidth. While Treasury yields and geopolitical frictions may still cause valuations to fluctuate, telecom remains a relatively more certain direction within the growth complex. Interested investors may consider the Telecom ETF (515880) for staged participation during volatility.

Looking ahead, the market's primary focus is the Fed meeting and tonight's U.S. CPI report. With nonfarm payrolls already strong and oil prices pinning energy-inflation expectations high, market odds for a 25bp September hike have risen to roughly 70% or higher—a completely different path from what was being debated a month ago. While the asset impact of a hike is typically most acute during the rapid expectation-repricing phase and some negative factors may clear once the decision lands, if the statement continues to emphasize energy-to-core inflation transmission, the rate floor will not come down, making it difficult for growth stocks to return to one-way repair territory.

In commodities, Brent closed around $107.6 on September 10 with a gain exceeding 7%, while WTI settled near $102.5, up over 8%. European gas prices also hit multi-year highs. Oil has moved from geopolitical premium to platform-level high volatility: Hormuz and Red Sea navigation disruptions, tanker attacks, and war-risk insurance costs are simultaneously tightening effective supply and shipping capacity. Surging VLCC daily charter rates indicate logistics premiums and crude premiums are resonating. Meanwhile, global inventories remain low and the Northern Hemisphere is entering restocking season, so the logic of a higher price center is not yet complete. However, risk-reward for chasing above $100 has deteriorated, and the risk of pullbacks during conflict de-escalation remains real.

Mapping to A-share oil chains, this week saw initial weakness, strength on Tuesday, then divergence—petrochemical names surged Tuesday before heavy pullbacks in the latter half, suggesting price elasticity has been traded. Fundamentally, upstream oil and gas company earnings are sensitive to a higher center for oil prices, oilfield services and equipment benefit with a lag via capex, while tanker shipping benefits from both freight rates and rerouting. Technically and from a trading perspective, the sector has moved from oversold pulses into a high-volatility zone with speculative participation. Interested investors may consider the Oil ETF (561360) for staged participation in the higher oil price center and geopolitical risk premium, though pacing and discipline against chasing are advised.

The defense sector has been gradually repairing from lows, with the CSI Defense Index gaining 1.47% this week and related products seeing expanding scale. The long thesis centers on military trade transactions: the December Zhuhai Airshow is entering its pre-event trading window, historically attracting positioning capital roughly two months before the show. Following the H1 reporting season, negative overhangs in infrared, military aircraft, and select ground equipment have largely cleared. The expectation gap in military trade lies in order placement potentially preceding public announcements amid geopolitical conflicts—increased foreign military transport aircraft visits and domestic equipment export frequency are read as evidence of delivery and combat-readiness demand. Some prime contractors' H2 and next-year order settlements may exceed the extremely pessimistic expectations of H1. Looking further, if the 15th Five-Year Plan for expanding military trade scale forms clear policy signals, it could become a sustained sector-level catalyst, with the centennial military narrative providing medium-term thematic altitude.

However, fundamental evidence remains to be verified. Bottom-up prosperity signals are lacking—July upstream defense orders declined both month-over-month and year-over-year, and component orders continued to face pressure after August's high-temperature holidays. The sector remains fundamentally a sentiment-driven rebound from low positioning. Additionally, commercial aerospace has become a notable drag, with launch catalysts like Zhuque-3 and Long March 10B severely underwhelming, keeping sector sentiment depressed even as the sustainability of future reusable-flight catalysts remains uncertain. Interested investors should track the 15th Five-Year Plan implementation, airshow catalysts, and upstream order turning points, potentially considering the Defense ETF (512660) for staged accumulation on dips.
