Why is Rossell Techsys falling/rising?

As of 22-Sep, Rossell Techsys Ltd's stock price is rising, currently at Rs. 788.00, reflecting an increase of Rs. 38.45 or 5.13%. The stock has recently hit a new 52-week high of Rs. 832 and has outperformed its sector by 5.82%. Over the past week, the stock has gained 5.21%, and in the last month, it has risen by 15.63%. The company reported very positive results with a 34.15% growth in net sales, and both profit before tax and profit after tax have shown significant growth compared to previous quarters. However, there are concerns regarding long-term fundamental strength, as indicated by a low return on capital employed and high debt levels, which may temper investor enthusiasm.
In the broader market context, Rossell Techsys has significantly outperformed the Sensex, which has only increased by 0.46% over the past week. The stock's strong performance is underscored by its consistent gains over the last four days, during which it has returned 7.78%. Despite these positive indicators, the falling investor participation, as evidenced by a 60.97% decline in delivery volume, raises questions about the sustainability of this upward trend. Overall, while the stock is currently rising due to strong recent performance and positive financial results, concerns about long-term fundamentals and liquidity may influence future price movements.
