The frenzy around “Suzhou Super League” concept stocks continues to intensify, with Jinling Sports (300651.SZ) surging by the 20% daily limit for three consecutive sessions. The sports equipment manufacturer has now disclosed that its stock price has doubled (+100.41%) over five trading days, formally crossing the threshold for “severe abnormal fluctuations” under exchange rules.
This parabolic rise comes as multiple companies linked to the Suzhou-based football tournament have seen their shares skyrocket, prompting at least two leading stocks to issue rare “cooling” announcements aimed at tempering investor enthusiasm. The disclosures represent an unusual intervention by listed firms to caution about speculative trading activity detached from fundamentals.
Market regulators are closely monitoring the situation as retail investors pile into these concept plays. Jinling Sports’ filing emphasized that no major undisclosed developments explain the violent price movements, while reminding shareholders about the company’s actual business scale and profitability levels. The statement follows similar warnings from other tournament-related stocks that have seen triple-digit percentage gains within weeks.
Analysts warn the buying spree reflects classic speculative bubble behavior, with valuations becoming increasingly disconnected from realistic growth prospects. The coordinated corporate warnings suggest authorities may be preparing more direct measures to stabilize these stocks if the volatility persists, though no trading restrictions have been imposed yet. The events highlight ongoing challenges in China’s markets where thematic investing often overwhelms fundamental analysis.
