Why is Epack Durable falling/rising?

As of 16-Jul, Epack Durable Ltd's stock price is currently at 381.35, reflecting an increase of 13.6, or 3.7%. The stock has shown strong performance recently, outperforming its sector by 4.25% today and achieving a consecutive gain over the last two days with a total return of 5.58%. In the past week, the stock has risen by 7.00%, and over the last month, it has increased by 10.63%. Despite a year-to-date decline of 30.75%, the stock has generated a remarkable return of 49.87% over the past year, significantly surpassing the market's return of 2.38%. The company has reported impressive growth in net sales and net profit, with a 33.30% annual growth rate in net sales and a staggering 1031.1% increase in net profit, contributing to its positive momentum.
In the broader market context, while Epack Durable's short-term performance has been strong, the benchmark Sensex has experienced a decline of 1.08% over the past week. However, the stock's recent gains come amidst a backdrop of falling investor participation, with a 6.62% drop in delivery volume compared to the five-day average, and a decrease in institutional investor stakes by 2.15%. This suggests that while the stock is currently rising, there are underlying concerns regarding management efficiency and valuation, as indicated by a low return on capital employed and a high enterprise value to capital employed ratio. These factors may pose risks to the stock's sustainability in the long term, despite its recent positive performance.
