Why is Epack Durable falling/rising?

As of 03-Sep, Epack Durable Ltd's stock price is rising, currently at Rs 398.70, reflecting an increase of Rs 10.7 or 2.76%. The stock has shown strong performance recently, gaining 6.21% over the last four days and outperforming its sector by 2.65% today. Additionally, the stock has delivered a remarkable 55.11% return over the past year, despite a year-to-date decline of 27.60%. Positive financial results, including a 94% growth in profit before tax and a 22.1% increase in net sales, contribute to the stock's upward momentum. However, concerns about management efficiency, indicated by a low return on capital employed (ROCE) of 8.32%, and a decrease in institutional investor participation may temper investor enthusiasm.
In the broader market context, Epack Durable's recent performance contrasts sharply with the benchmark Sensex, which has seen a slight decline of 0.27% over the past week and a negative return of 0.04% over the last month. This divergence highlights the stock's ability to attract investor interest despite broader market challenges. While the stock has outperformed the BSE500 index, which has generated negative returns of -4.38% in the last year, the overall market sentiment remains cautious, particularly given the declining stake of institutional investors.
