Why is High Street Fila falling/rising?

As of 04-Sep, High Street Filatex Ltd's stock price is currently at Rs. 206.80, reflecting an increase of Rs. 8.8 or 4.44%. The stock has recently hit a new 52-week and all-time high of Rs. 207.9, outperforming its sector by 5.51%. Over the past six days, the stock has shown a remarkable gain of 28.49%. Additionally, it has delivered impressive returns of 212.86% over the past year and 397.12% over the last three years, indicating strong long-term performance. However, the company is facing challenges, including operating losses and a weak ability to service its debt, which has led to negative returns on equity and a decrease in promoter confidence, as they have reduced their stake by 24.44%.
In the broader market context, High Street Filatex Ltd has significantly outperformed the Sensex, which has only increased by 0.80% over the past week, while the stock itself has surged by 22.40%. This stark contrast highlights the stock's strong performance relative to the benchmark. Despite its recent gains, the company's underlying financial issues, including negative EBITDA and reported losses, suggest a level of risk that investors should consider. The combination of high returns and operational challenges creates a complex picture for potential investors.
