Why is SPP Polymer falling/rising?

As of 22-Sep, SPP Polymer Ltd's stock price is currently at 17.05, reflecting a decrease of 0.55 or 3.13%. The stock has underperformed its sector today by 2.43%. In terms of returns, over the past week, the stock has gained 0.29%, but it has significantly underperformed over the longer term, with a year-to-date decline of 47.70% and a one-year drop of 66.76%. The stock is trading higher than its 20-day moving average but lower than its 5-day, 50-day, 100-day, and 200-day moving averages. Additionally, there has been a notable increase in investor participation, with delivery volume rising by 42.86% against the 5-day average, indicating some interest despite the overall negative price movement.
Broader market context shows that while SPP Polymer's short-term performance over the past week is positive, it still lags behind the Sensex, which has increased by 0.53% in the same period. The stock's year-to-date performance is starkly negative compared to the Sensex's gain of 6.59%, highlighting a significant divergence in performance. This broader market context suggests that while there may be some short-term interest in SPP Polymer, the overall market sentiment and the company's long-term performance are contributing to its declining stock price.
