Why is Aviva Industries falling/rising?

As of 06-Oct, Aviva Industries Ltd's stock price is currently at Rs 55.12, reflecting an increase of Rs 1.08 or 2.0%. The stock has been gaining for the last two days, with a notable return of 4.02% over the past week, outperforming the Sensex, which has only risen by 1.77% in the same period. Additionally, the stock is close to its 52-week high, being just 2.38% away from Rs 56.43. It opened with a gain of 2% today and has maintained this price level throughout the trading session. However, there has been a significant drop in investor participation, with delivery volume falling by 98.82% against the 5-day average, indicating a potential concern for future trading activity.
In the broader market context, Aviva Industries' short-term performance has been strong compared to the benchmark, as it has outperformed the Sensex over the last week. The stock's consistent gains and its position above various moving averages suggest a positive trend, although the erratic trading behavior, with no trades on three days out of the last twenty, raises some caution. The lack of available positive or negative factors further complicates the analysis, but the current upward movement in price and recent performance indicates a favorable sentiment among investors, despite the declining delivery volume.
