Ming Yang Smart Energy Group's ROCE trend is disappointing, with diminishing returns over the past five years. The company's investments haven't boosted sales, and the high current liabilities to total assets ratio poses risk. The stock's 15% return over the last five years suggests better investment opportunities may exist elsewhere.

Potential risks might pressure Ming Yang Smart Energy Group's P/E ratio, despite a strong earnings growth forecast. These risks could be due to expected market volatility and uncertainty of future earnings.
