Why is Vas Infra. falling/rising?

As of 06-Oct, Vas Infrastructure Ltd is experiencing a price increase, currently at Rs. 18.40, which reflects a rise of 0.28 (1.55%). The stock has recently hit a new 52-week high of Rs. 19.02 and has outperformed its sector by 1.1%. Over the last three days, the stock has gained 14.14%, contributing to an impressive annual return of 318.18%. However, it is important to note that the stock has shown erratic trading patterns, not trading on 3 out of the last 20 days, and there has been a significant decline in investor participation, with delivery volume dropping by 69.3% against the 5-day average.
In the broader market context, while the Sensex has shown a modest increase of 1.77% over the past week and 1.34% over the past month, Vas Infrastructure's recent performance stands out significantly. The stock's strong returns over the past year and three years, at 318.18% and 349.88% respectively, highlight its robust performance compared to the benchmark's minimal growth of 0.12% and 40.48% in the same periods. Despite the positive price movement, the declining delivery volume suggests potential concerns regarding sustained investor interest, which could impact future performance.
