Why is Essen Speciality falling/rising?

As of 05-Aug, Essen Speciality Films Ltd is experiencing a price increase, with the current price at Rs 487.95, reflecting a rise of 23.2 points or 4.99%. Today's price summary indicates that the stock opened with a gain of 3.5% and reached an intraday high of Rs 487.95, outperforming its sector by 5.18%. Over the past week, the stock has shown a significant return of 27.59%, while its one-year performance remains impressive at 280.39%. However, the company faces challenges, including a declining operating profit growth rate of -14.11% over the last five years and a recent drop in profit before tax and profit after tax in the latest quarter. Additionally, the stock is trading at a premium compared to its peers, with a price-to-book value of 7.9, which may deter some investors.
In the broader market context, Essen Speciality's short-term performance contrasts sharply with the benchmark Sensex, which has declined by 0.69% over the past week. While the stock has shown strong returns in the past year, its recent negative results and low investor participation, indicated by a decrease in delivery volume, suggest potential caution among investors. The lack of domestic mutual fund investment may also reflect a lack of confidence in the stock's valuation and long-term growth prospects, despite its recent price increase.
