Despite Jilin Quanyangquan's recent share price rise, its medium-term revenue decline and high P/S ratio could disappoint shareholders if the P/S falls in line with negative growth rates. The company's future may be challenging unless the revenue decline improves.

Jilin Quanyangquan's declining ROCE and reduced capital employed hint at potential competitive challenges. Despite this, the stock has seen a 91% return over the past five years. However, the fundamentals do not inspire confidence for future performance.

Despite Jilin Quanyangquan's high P/S ratio and declining medium-term revenue, many investors retain their stock. A fall in the P/S may adversely affect market sentiment in the long term.

Despite Jilin Quanyangquan's low ROE, the company's exceptional net income growth over the past five years suggests that there could be other positive factors at play, such as effective strategic decisions by management or a low payout ratio.
