Why is Aviva Industries falling/rising?

As of 19-Sep, Aviva Industries Ltd's stock price is currently at 49.96, reflecting a decline of 3.19, or 6.0%. The stock has underperformed its sector by 5.54% today and opened with a significant loss of 6%. It has not traded on 5 out of the last 20 days, indicating erratic trading behavior. Despite this, there has been a notable increase in investor participation, with delivery volume rising by 307.81% against the 5-day average. The stock's performance over the past year shows a substantial increase of 108.43%, contrasting with the Sensex's slight decline of 0.67%, but the current price movement suggests a negative trend in the short term.
In the broader market context, the Sensex has shown a positive return of 0.88% over the past week and 1.20% over the past month, indicating a generally favorable market environment. However, Aviva Industries' recent performance has not aligned with this trend, as it has experienced a significant drop today. The stock's current price is higher than its 20-day, 50-day, 100-day, and 200-day moving averages, but lower than its 5-day moving average, suggesting a recent shift in momentum. Overall, while the stock has performed well over the longer term, recent trading activity and market conditions have contributed to its current decline.
