1. This limit-up is a momentum-driven market without fundamental catalysts, with high volatility; attention should be paid to fluctuations caused by emotional changes [0].
2. The low price-to-book ratio indicates potential undervaluation, but the company’s weak profitability (ROE 1.25% and net profit margin 3.35%) limits the long-term fundamental support for the market [0].
3. The combination of overbought RSI and near 52-week high increases the probability of short-term correction [0].

• Short-term correction risk
  : Overbought RSI indicates the stock price is at a short-term high, which may trigger profit-taking [0].
• Insufficient fundamental support
  : The company’s weak profitability is difficult to support the long-term rise of the stock price [0].
• Volatility risk
  : Momentum-driven markets are susceptible to market sentiment, leading to large fluctuations [0].

• Continuation of technical momentum
  : If it breaks through the current resistance level of 8.89 USD, the stock price may continue to rise to 9.23 USD [0].
• Value investment opportunity
  : The low price-to-book ratio is still attractive; if the company’s profitability improves, there is room for long-term valuation repair [0].
