1. Short-term market driven by technology and capital
   : Continuous上涨 and increased trading volume reflect technical breakthroughs and the influx of speculative funds, rather than fundamental improvements.
2. Fundamentals and valuation divergence
   : The company’s net profit margin (-0.78%) and ROE (-1.93%) are both negative, and the TTM PE reaches -110.72 times, so the valuation lacks fundamental support [0].
3. Overbought signals need vigilance
   : The RSI indicator shows overbought, and similar signals in history are often accompanied by short-term callbacks [0].

• Risks
  : Weak fundamentals, lack of substantive positive news; RSI overbought, high short-term callback risk; if trading volume cannot be maintained, the stock price is prone to decline.
• Opportunities
  : If it can break through the next target price of 13.35 yuan and maintain trading volume, the short-term may continue to rise; close attention should be paid to whether positive news appears in the overall industry trend.

Daye Co., Ltd. (603278) hit the limit up in the short term due to technical breakthroughs and capital promotion, with positive market sentiment, but there are major risks in fundamentals and valuation. Investors need to pay attention to changes in trading volume, the repair of technical indicators, and industry dynamics, and judge the sustainability of the market cautiously.
