Why is SPP Polymer falling/rising?

As of 28-Aug, SPP Polymer Ltd's stock price is currently at 16.50, showing no change (0.00%). The stock has underperformed in the past week and month, with a decline of 4.62% in both periods. Additionally, it has experienced a significant year-to-date drop of 49.39%, contrasting sharply with the Sensex, which has risen by 3.62% during the same timeframe. Today's performance indicates that SPP Polymer has outperformed its sector by 1.39%, but it is trading below all key moving averages, suggesting a bearish trend. Furthermore, investor participation has decreased, with delivery volume falling by 46.43% compared to the five-day average. The stock does offer a high dividend yield of 3.03%, which may provide some support to its price.
In the broader market context, SPP Polymer's recent performance is notably weaker than the benchmark Sensex, which has declined by only 2.32% over the past week and 0.73% over the past month. This stark contrast highlights the challenges faced by SPP Polymer in attracting investor interest, especially given the significant year-to-date decline. The liquidity of the stock appears adequate for trading, but the overall negative sentiment reflected in the stock's performance metrics suggests that investors are cautious, likely due to the company's ongoing struggles and declining participation.
