Why is Aviva Industries falling/rising?

As of 11-Jun, Aviva Industries Ltd's stock price is rising, currently at Rs. 48.19, reflecting an increase of 0.94 or 1.99%. The stock has reached a new 52-week high today and has been on a positive trajectory, gaining for the last 13 consecutive days with a total return of 29.16% during this period. Additionally, the stock has significantly outperformed the sector by 2.18%. Over the past year, Aviva Industries has shown impressive growth with a 101.04% increase, while its performance over three years stands at 59.57%. However, there has been a noted decline in investor participation, with delivery volume falling by 37.54% against the five-day average, which could indicate a potential concern for future momentum.
In the broader market context, Aviva Industries' short-term return of 10.35% over the past week significantly outpaces the Sensex's return of 1.87%, highlighting its strong performance relative to the benchmark. This outperformance, combined with the stock trading above all key moving averages, suggests robust investor confidence. Despite the decline in delivery volume, the overall liquidity remains sufficient for trading, indicating that while some investors may be pulling back, the stock's upward trend is supported by strong historical performance and current market conditions.
