Why is Epack Durable falling/rising?

As of 13-Aug, Epack Durable Ltd's stock price is currently at Rs 376.00, reflecting an increase of 1.05 (0.28%). The stock has shown a trend reversal, gaining after two consecutive days of decline. It reached an intraday high of Rs 383.3, which is a 2.23% increase. However, the stock has underperformed its sector by 1.24% today and has experienced a significant drop in delivery volume, falling by 72.6% compared to the 5-day average. Over the past week, the stock has decreased by 1.31%, while it has performed better over the past month with a 2.12% increase. Despite a year-to-date decline of 31.72%, the stock has generated impressive returns of 56.08% over the past year, significantly outperforming the market, which has seen a return of only 2.01%. However, the company faces challenges such as low management efficiency, indicated by a return on capital employed (ROCE) of 8.32%, and a decrease in institutional investor participation.
Broader Market Context: In the short term, Epack Durable's performance has been weaker than the benchmark, as evidenced by its 1-week decline of 1.31% compared to the Sensex's negligible change of -0.01%. While the stock has shown strong long-term growth with a net sales increase of 33.30% annually and positive quarterly results, the falling participation from institutional investors, who have reduced their stake by 2.19%, raises concerns about its future performance. The stock's current valuation appears expensive given its low ROCE and a PEG ratio of 1.1, which may deter potential investors despite its recent gains.
