Why is Deep Polymers falling/rising?

As of 10-Sep, Deep Polymers Ltd is currently priced at 50.95, reflecting an increase of 0.83, or 1.66%. The stock has shown a positive trend recently, gaining 1.8% over the last two days and outperforming its sector by 1.08% today. Despite this short-term gain, the stock has underperformed over the longer term, with a year-to-date decline of 25.70% and a staggering 42.10% drop over the past year. The company has a low Debt to Equity ratio of 0.45, indicating manageable debt levels, and has demonstrated healthy long-term growth with an operating profit growth rate of 40.02%. However, the stock's profitability is hindered by a low Return on Capital Employed (ROCE) of 5.7, and its profits have decreased by 23.3% over the past year, contributing to investor caution.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has gained 1.06% over the past week and 1.96% over the past month. Deep Polymers has consistently underperformed against the benchmark over the last three years, with a significant decline in returns compared to the BSE500. While rising promoter confidence, with a 0.66% increase in stake, suggests optimism about the company's future, the overall negative sentiment stemming from poor management efficiency and recent financial results may overshadow these positive indicators.
