China's majors limped out of the gate and sprinted into the finish. The CSI 300, down as much as 1.6% intraday, ended up 0.2%. The Star 50, packed with tech hardware names, clawed back nearly a 5% fall.
Activity across eight exchange-traded funds that are frequently associated with the "National Team" climbed to nearly 30 billion yuan ($4.5 billion), marking the heaviest turnover in almost two months. Some participants also said bargain hunters stepped in after the week's hit.
No single spark was confirmed. Traders pointed to circulating screenshots that referenced unverified regulatory "window guidance" to rein in selling, and others pointed to the kind of buying associated with the state-linked "National Team." Speaking as the chief investment officer for Shanghai Chengzhou Investment Management, Fu Zhifeng put it this way: "There's market chatter claiming regulator have issued window guidance to funds and insurers to limit sell orders, although I haven't heard any confirmation from companies yet."
At Lotus Asset Management in Hong Kong, chief investment officer Hao Hong sees the support as a signal derived from the charts.

Confidence has been frayed. A set of targeted moves in late September didn't match the all-in stimulus Beijing used in prior swoons. The CSI 300 is lingering near a one year low, and the Star 50 is on the verge of wiping out its 2024 gain, which at one stage had reached 64%.
After mainland markets reopened Thursday from a week-long break, stocks were pressured by tepid spending signs and rising doubts around the AI theme. Optical and chip names that had ridden Beijing's AI ambitions were among the hardest hit as investors focused more on earnings and valuations.
There were a few bright spots. Some buyers likely bottom-fished after the slide, and fresh Golden Week reads showed improvement in housing activity, with tracking across 25 major cities indicating new home sales moved higher.
One afternoon surge does not fix a confidence problem. What matters next: whether any formal policy support shows up, if the "line in the sand" on the Shanghai Composite continues to hold, and how earnings stack up for the hardware names that powered earlier AI hopes. If you have China exposure, the near term may be choppy, and the bigger story will be told by policy follow through and demand data rather than intraday heroics.
