Why is Classic Filament falling/rising?

As of 22-Sep, Classic Filaments Ltd is experiencing a price increase, currently at Rs 25.78, which reflects a rise of Rs 1.23 or 5.01%. Despite opening with a loss of 5.5% today, the stock managed to reach an intraday high of Rs 26.99, indicating significant volatility with a wide trading range of Rs 3.79. Over the past week, the stock has outperformed its sector by 5.72%, and it has shown a positive return of 8.64% over the last week and 10.64% over the last month. However, there has been a notable decline in investor participation, with delivery volume dropping by 39.21% against the five-day average, which could be a concern for future price stability.
Broader market context shows that while Classic Filaments has had a strong short-term performance, it still lags behind the benchmark Sensex in year-to-date returns, with a decline of 13.92% compared to the Sensex's increase of 5.15%. The stock's long-term performance remains robust, with a remarkable increase of 260.56% over three years and 296.62% over five years, significantly outpacing the benchmark's returns during the same periods. This suggests that while the stock is currently rising, it is essential to consider the broader market trends and the recent drop in investor participation, which may impact future performance.
