Why is Hind.Fluoro Carb falling/rising?

As of 16-Sep, Hindustan Fluoro Carbons Ltd is experiencing a decline in its stock price, currently at 15.65, which reflects a decrease of 0.15 or 0.95%. The stock has shown mixed performance recently, with a 1-week return of -0.32% and a 1-month return of +2.15%. However, it has underperformed significantly over the past year, with a return of -20.03%. Today's price summary indicates that the stock has outperformed its sector by 0.75%, and it is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Despite these positive indicators, the stock faces challenges such as a negative book value and weak long-term fundamentals, with net sales declining at an annual rate of -100.00% and a high debt-to-equity ratio, which raises concerns about its financial stability.
In the broader market context, the stock's performance has lagged behind the benchmark, with the Sensex gaining 1.58% over the past week while Hindustan Fluoro Carbons Ltd has declined. The company has also underperformed the market over the past year, where the BSE500 index saw a smaller decline of -2.93%. The significant drop in investor participation, with a 74.49% decrease in delivery volume compared to the 5-day average, further indicates a lack of confidence among investors. Overall, while there are some short-term positive indicators, the long-term outlook remains concerning, contributing to the stock's current downward movement.
