China's SSE Composite Index closed Friday at 4,027.27 points, declining 2.26% for the week ending June 27, 2026. According to latest reports, this marked one of the most difficult weeks in months for mainland Chinese equities, with the Shenzhen Component Index falling even more sharply at 3.44% on Friday. The benchmark had reached the 4,100 level earlier in June before reversing course, reflecting a combination of external pressures from global technology valuation corrections and internal factors including concerns about China's economic recovery pace.
The technology and semiconductor sector was the epicentre of the week's losses, with the global repricing of artificial intelligence valuations triggered by reports of a potential OpenAI IPO delay and concerns about hyperscaler spending sustainability. Semiconductor Manufacturing International Corporation (SMIC) corrected sharply as the broader sector came under pressure, despite having been a beneficiary of China's domestic AI infrastructure investment cycle in earlier months of 2026. Major internet platforms including Alibaba, Baidu, and Tencent faced uncertainty about their AI investment commitments amid the global valuation concerns originating in the United States. The Nasdaq has risen roughly 25% in just two months, driven by technology leaders like Nvidia (NVDA) and other AI companies, making the sector especially sensitive to rate expectations and global tech sentiment.
The People's Bank of China announced on June 25 that it would add overnight reverse repo products in open market operations on June 29-30, a technical liquidity management measure that demonstrated the central bank's attentiveness to short-term funding conditions as the quarter closed. As reported by Business Standard, these measures provided the catalyst for investor confidence to return to Chinese equities, with the central bank's intervention helping to stabilize market conditions. The PBOC's proactive announcement of additional liquidity facilities ahead of the quarter-close was interpreted by market participants as a signal that the central bank was committed to preventing any disorderly tightening of short-term funding conditions, even as global risk appetite deteriorated.
Financial stocks provided relative stability during the week, with Industrial and Commercial Bank of China rising 0.98%, Agricultural Bank of China gaining 0.81%, and China Construction Bank adding 0.50%. According to Business Standard, the banking sector's strong performance reflected investor confidence in the financial system's stability following the central bank's liquidity support measures. The PBOC's supportive signal from the June 25 announcement limited the downside in bank stocks and helped prevent a more severe overall market decline, demonstrating the effectiveness of the central bank's proactive approach to managing short-term funding conditions.
The SSE Composite's proximity to the 4,000 level represents a technically important zone, with the index having repeatedly attracted buying interest near this level during the current cycle. As reported by market analysts, resistance lies in the 4,100 to 4,150 range, which capped the index's attempts to extend higher during the June rally. The index's 52-week range of approximately 3,300 to 4,250 illustrates the significant recovery Chinese equities have made from earlier 2025 lows. Looking ahead, the June manufacturing PMI scheduled for release on June 30 will be the most significant domestic economic data point, with consensus expectations for a modest rebound above the 50 boom-bust line that separates expansion from contraction. The S&P 500 recently cleared the 7,600 level for the first time, but underlying economic indicators show growth slowing, inflation re-accelerating, and consumer sentiment hitting an all-time low in the University of Michigan survey.
