Jiangnan Mould & Plastic Technology's low P/E, due to poor three-year earnings trends, suggests shareholders expect no future earnings surprises. If these trends persist, a strong share price rise seems unlikely.

Investors may believe Jiangnan Mould & Plastic Technology's earnings growth will underperform the broader market, impacting its low P/E ratio. The company's unstable medium-term growth rates and underperformance may continue to negatively affect the share price.
