Why is AVI Polymers falling/rising?

As of 25-Sep, AVI Polymers Ltd is experiencing a decline in its stock price, currently at 13.91, reflecting a decrease of 0.6 or 4.14%. The stock has underperformed its sector today by 2.01%, and it is trading lower than its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Additionally, the stock's delivery volume has fallen significantly, with a decrease of 39.47% compared to the 5-day average. Over the past week, the stock has seen a decline of 6.33%, while its performance over the last month shows a slight decrease of 0.71%. The year-to-date return stands at 11.19%, indicating some positive momentum, but the recent trends suggest a negative shift in investor sentiment.
In the broader market context, the Sensex has also faced a decline of 2.23% over the past week, which is less severe than AVI Polymers' performance. This indicates that while the overall market is down, AVI Polymers is underperforming relative to the benchmark. The stock's year-on-year return of 11.28% contrasts with the Sensex's decline of 4.71%, suggesting that AVI Polymers had previously outperformed the market. However, the recent drop in investor participation and the overall negative action in the sector, which has fallen by 2.15%, may be contributing to the stock's current downward trend.
