Why is Polysil Irrigati falling/rising?

As of 06-Oct, Polysil Irrigation Systems Ltd is experiencing a price increase, with its current price at 267.00, reflecting a rise of 5.0 (1.91%). The stock has shown strong performance recently, with a 1-week return of +6.63% and an impressive 1-month return of +116.02%. However, despite this positive momentum, there is a notable decline in investor participation, as evidenced by a significant drop in delivery volume, which has fallen by -99.08% compared to the 5-day average. Additionally, while the stock is currently higher than its 5-day moving average, it remains below its longer-term moving averages, indicating some volatility in its price trend.
In the broader market context, Polysil's recent performance has outpaced the Sensex, which has only increased by +1.80% over the same 1-week period. This suggests that while the stock is performing well relative to the market, the drastic decline in delivery volume may raise concerns among investors regarding its sustainability. The stock's year-to-date return of +863.90% further highlights its strong performance compared to the Sensex's +6.06%, indicating that Polysil has been a standout performer in the market despite the recent drop in trading activity.
