Why is Polysil Irrigati falling/rising?

As of 05-Aug, Polysil Irrigation Systems Ltd is experiencing a price increase, with its current price at 121.20, reflecting a rise of 2.35 or 1.98%. The stock has shown strong performance recently, with a weekly return of +12.43% and a monthly return of +52.84%, significantly outperforming the Sensex, which has declined by 0.69% over the same week and 3.19% over the month. However, despite this positive momentum, there is a notable decline in investor participation, as evidenced by a dramatic drop in delivery volume, which has fallen by 99.08% compared to the 5-day average. The stock is currently liquid enough for trading, based on 2% of the 5-day average traded value.
In the broader market context, Polysil's strong short-term performance stands in stark contrast to the benchmark Sensex, which has not only underperformed in the past week and month but also shows a modest year-to-date gain of 4.25%. This divergence indicates that while Polysil is gaining traction among investors, the overall market sentiment may not be as favorable. The stock's performance over the past year, with a remarkable increase of 251.30%, further highlights its resilience and appeal, especially in a market that has seen limited growth.
