Shanghai Jiubai Says Operations Normal After 5 Straight Limit-Ups, 61% Gain

The company's own filing is the story here: management is explicitly labeling the rally as overheated sentiment and irrational speculation rather than pointing to any fundamental catalyst, which is an unusually direct disclaimer from an issuer. That matters most for anyone holding the stock on the assumption that a business development explains the move — the company says there is none. The open question is whether the exchange's abnormal-trading triggers draw further scrutiny, and whether the limit-up streak persists once the company has publicly distanced itself from the gains.
