Why is Polysil Irrigati falling/rising?

As of 01-Jul, Polysil Irrigation Systems Ltd is experiencing a price increase, with its current price at 74.80, reflecting a rise of 1.45 or 1.98%. The stock has shown strong performance recently, with a 10.24% increase over the past week and a remarkable 52.81% rise over the last month. However, despite this upward trend, 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. The stock's performance today has outpaced its sector by 5.56%, but it is currently trading above its 5-day moving average while remaining below the longer-term moving averages of 20, 50, 100, and 200 days.
In the broader market context, Polysil's returns have significantly outperformed the Sensex, with a year-to-date increase of 170.04% compared to the Sensex's 8.02%. This stark contrast highlights the stock's strong momentum relative to the benchmark. However, the falling investor participation could indicate a potential concern for future price stability, as liquidity remains adequate for trading. Overall, while the stock is currently rising, the decline in delivery volume may suggest caution among investors moving forward.
