Why is AVI Polymers falling/rising?

As of 17-Jul, AVI Polymers Ltd is experiencing a price increase, currently at 16.56, reflecting a rise of 0.78 or 4.94%. The stock has shown strong performance recently, with a 1-week return of +6.77% and a 1-month return of +11.82%, significantly outperforming the Sensex, which has seen a decline of -1.12% over the same week and a modest gain of +0.83% over the month. Additionally, AVI Polymers is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. However, it is important to note that investor participation has decreased, with delivery volume falling by -34.14% compared to the 5-day average, which may suggest a potential concern for future trading activity.
In the broader market context, AVI Polymers' year-to-date return of +32.37% and 1-year return of +41.30% starkly contrast with the Sensex's year-to-date gain of only +5.27% and 1-year gain of +1.91%. This indicates that while the stock is performing exceptionally well compared to the benchmark, the recent decline in investor participation may pose a risk to its upward momentum. The liquidity of the stock remains adequate for trading, as it is based on 2% of the 5-day average traded value, which supports ongoing trading activity despite the drop in delivery volume.
