Keysino Separation Technology's high P/E ratio and recent poor growth rate may be worrying. Investors could face disappointment if the P/E aligns with the negative growth rates. Current prices may seem unreasonable given the high P/E and shrinking earnings, unless medium-term conditions significantly improve.

Keysino Separation Technology's declining ROCE and sales trend is worrisome. Their reinvestment for growth appears ineffective, losing market share. The market mirrors these negative trends with an 11% stock depreciation over the last three years.

Keysino Separation Technology's recent revenue decline and high P/S ratio are concerning. If revenue trends persist, it could risk shareholders' investments and deter prospective investors.
