Why is Vas Infra. falling/rising?

As of 07-Oct, Vas Infrastructure Ltd is experiencing a price increase, with the current price at Rs. 19.32, reflecting a rise of Rs. 0.92 or 5.0%. The stock has reached a new 52-week high today and has outperformed its sector by 4.6%. Over the past four days, the stock has gained 19.85%, indicating strong momentum. Additionally, it is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, which suggests a positive trend. However, there has been a notable decline in investor participation, with delivery volume dropping by 68.29% compared to the 5-day average, indicating potential concerns about sustainability in the stock's upward movement.
In the broader market context, while the Sensex has shown a positive return of 2.07% over the past week and 1.51% over the past month, the stock's performance over the last year has been exceptional, with a return of 362.20%, significantly outperforming the benchmark's 1.08%. This stark contrast highlights the stock's strong performance relative to the market. Despite the recent gains, the erratic trading pattern, where the stock did not trade on two days out of the last 20, may raise questions about its liquidity and stability moving forward.
