Fujian Nanping Sun Cable's declining ROCE trend and stagnant sales growth despite reinvestment raise doubts about its multi-bagger potential. The company's high self-funding reliance may also be impacting its ROCE efficiency.

Investors' belief that the company's earnings growth may underperform the broader market in the near future could explain the low P/E ratio. If limited growth rates persist, investors may only pay a reduced amount for the stock, as the potential for earnings improvement doesn't justify a higher P/E ratio.

Fujian Nanping Sun Cable's high ROE is positive, but its significant debt usage is worrisome. Despite the debt, the company's ROE remains low, which is unfavorable. Top-tier companies usually boast high ROE and low debt.
