As soon as the bad news came out, the whole sector collectively hit limit-down.
Tips
usage
On China's A-share market, stocks can move at most ±10% in a trading day (±20% on ChiNext/STAR Board, ±5% for ST shares). Hitting that floor is 跌停; hitting the ceiling is 涨停.
memory
跌 = fall + 停 = stop → fall until it stops (trading is frozen at the limit).
