What happened (real data)
Closed at CNY 49.38, -6.41% on the day — the largest one-day move in the window 2025-09-04~2026-09-30; volume was about 2.6x the prior 20-day average.
The next 5 sessions
Five sessions later it closed at CNY 47.23, -4.35% in total — the move continued. One example proves nothing about the future.
In plain English
The biggest move of the year is when emotion is fullest, not when opportunity is largest. Without a written plan, both regret and hope lead to impulsive orders.
Trap to avoid
Takeaway: decide where you exit if wrong before you decide to act.
Cause checks use price versus index only; filings and fund flows are not verified. For trading-review education only — not investment advice and not a forecast.
