Jiangsu Luokai Mechanical & Electrical's low P/E ratio is due to its three-year earnings trends falling short of market expectations. Investors anticipate no pleasant surprises in future earnings, forming a barrier for the share price.

Chengdu Haoneng Technology's lower P/E and share price drop, despite forecasted growth, may indicate investor skepticism about its ability to meet future growth expectations and potential unobserved threats to earnings.

Chengdu Haoneng Technology is reinvesting for growth and has experienced higher sales. Meanwhile, the company's stock rose 92% over the last five years, indicating investor optimism.

Chengdu Haoneng Technology's moderate income growth, despite an industry-standard ROE, indicates good earnings retention and effective management. Industry forecasts predict their earnings will increase.
