The Shanghai Stock Exchange (SSE) Composite Index closed the week on a sombre note, slipping 0.25% to finish at 4,065.58 on Friday. This daily decline capped a volatile week that saw the benchmark index retreat 1.27%, marking a distinct pause in the blistering rally that has defined the early months of 2026. Market participants are increasingly moving to the sidelines, weighing the sustainability of high valuations against a backdrop of cooling global technology sentiment and mixed domestic corporate signals.

Global Tech Spillover & AI Concerns

The primary driver of this week’s bearish sentiment was the negative feedback loop from global markets, particularly the steep selloff in technology equities. Investors are reassessing the aggressive capital expenditure associated with Artificial Intelligence (AI), questioning the immediate return on investment for the massive spending boom. This caution spilled over into Chinese markets, heavily impacting shares related to AI applications and traditional software models. While the broader market struggled, specific niche sectors such as robotics and solid-state batteries managed to buck the trend, suggesting that capital is rotating rather than exiting the market entirely.

EV Sector Headwinds and Corporate Earnings

Adding to the market’s weight was the disappointing performance in the electric vehicle (EV) sector, a critical pillar of China’s high-tech manufacturing growth. BYD, a bellwether for the industry, released sales data that missed analyst expectations, raising alarms about slowing domestic demand and the ongoing pressure of rising raw material costs. This fueled a broader pullback in the auto supply chain, dampening risk appetite. Additionally, weakness in tourism stocks indicated a potential cooling in consumer discretionary spending following the holiday season peaks.

Technical Resistance and Decreasing Volume

From a technical perspective, the index is clearly consolidating after failing to breach its 52-week high of 4,190.87. The red candle on the weekly chart highlights a “profit-taking” mode, with the index now testing the lower bounds of its recent trading range. Notably, trading volume on Friday tapered off, with the combined turnover of the Shanghai and Shenzhen exchanges totaling 2.15 trillion yuan—a decrease from the previous session. This lower volume on a down day may indicate that while buyers are hesitant, there is not yet a panicked rush to the exits. The psychological level of 4,000 remains the critical support zone to watch; a breach below this could invite further technical selling.

Looking ahead, investors should monitor whether the index can stabilize above the 4,000 mark in the coming week. The focus will likely shift to the release of post-Lunar New Year corporate earnings, which will provide a clearer picture of fundamental health beyond the immediate sentiment-driven volatility. Traders will also be keeping a close eye on global commodity prices, specifically metals, which have shown heightened volatility and could further impact the cost structures of China’s manufacturing giants.
