China Retail Bought the Dip as ChiNext Fell 1.71% - Sentiment 56.6, Robots Rotate

Monday's A-share session ended with the indices pulling in two directions - and the crowd pulling in a third. The Shanghai Composite closed at 3697.52, up 0.19%, while the ChiNext slumped 1.71% to 2638.23 (Shenzhen -1.19%, CSI300 -0.04%). On a red day for growth stocks, our full-population scan of retail stock-forum chatter says Chinese retail traders did the opposite of panicking.

The Tape Fell. The Crowd Didn't.

We scored every one of 970 retail comments from Eastmoney and Sina stock forums (window: Oct 25 22:02 - Oct 26 22:02, 20 hot names; 899 from Eastmoney, 71 from Sina). The daily sentiment index landed at 56.6 out of 100 - neutral leaning bullish - with bears at just 11.4% of all posts.

The kicker is the trend, not the level: the 24-hour bullish share came in at 24.6%, up nearly four points from 20.7% over the 48-hour window. In other words, on the day the ChiNext dropped 1.71%, retail got bolder, not scared. For context, the limit-up pool still counted 82 names on Oct 23 (Eastmoney data), so the short-term momentum crowd is alive and well.

Rotation Target: Humanoid Robots

Where did the heat go? Almost entirely into humanoid robots and physical AI. Unitree Robotics (688836), freshly listed, stormed onto the Dragon-Tiger list and into the top-3 forum hot words. Shangwei New Material (688585) locked a 20% limit-up while forum posters cheered to hold the board. The single most-bullish thread was robotics-chain auto-parts name Moxing Technology (000700): 60 comments, sentiment 61.6, and only 3.3% of posters bearish.

But the same hot-word table also surfaced defensive terms - bond funds, dividend names. Attackers chased robots, defenders hid in dividends, and the mid-tier growth belt in between got left holding the decline. That is exactly why the ChiNext fell hardest while the SSE held green. This is a rotation, not an exodus.

Private Funds Quietly Switched Tools

While forums debated direction, institutions moved tools. As of Oct 25, 151 private fund managers appear among the top-10 holders of 207 ETFs launched this year, holding a combined 2.325 billion units (PaiPaiWang data). Sixteen managers with 10B+ yuan AUM held 373 million units - 16.04% of those funds' shares. Funds that trade stocks are buying broad-market baskets.

The strategy scoreboard explains why: for the week to Oct 16, 66.08% of quant CTA products posted positive weekly returns versus 39.90% for discretionary CTA. In a wide, directionless range, trading volatility beat betting on direction by 26 percentage points. If your P&L depends on calling direction, that gap is the lesson.

AI Walks Into the Market

The AI trade is about to get a quarterly report card. Anthropic, the maker of Claude, filed its S-1 with the US SEC on Oct 26 - the formal first step toward a US listing. Frontier-AI economics will soon be audited in public every quarter instead of narrated in funding press releases. Note the usual caveat: every growth story in an S-1 is written by the company selling it.

Two more data points from the same week: Moonshot's Kimi K3.1 Pro scored 55 on Artificial Analysis and landed on the price-performance Pareto frontier (Oct 23), drawing 1086 points on Hacker News; and chip startup Cerebras said it deployed a trillion-parameter model for enterprise inference (Oct 25). Cheap frontier tokens plus on-prem scale is exactly the mix equity markets are repricing.
