Despite past EPS declines, optimism remains for Jiangsu Sanfame's long-term earnings stability. However, last year's performance suggests unresolved challenges, indicating a need for investor caution.

Jiangsu Sanfame Polyester MaterialLtd's ROCE trend is disappointing, with returns dropping in the past five years. The 10% stock decline over the same period may indicate investor skepticism about any improvement.

Jiangsu Sanfame's stable ROCE, coupled with a substantial capital increase, implies a dearth of profitable reinvestment opportunities. The mere 18% return over five years doesn't instill confidence in potential investors, given the company's failure to generate superior returns despite enhanced capital deployment.
