Why is Epack Durable falling/rising?

As of 16-Sep, Epack Durable Ltd's stock price is currently at 377.35, reflecting a decrease of 1.15, or 0.3%. The stock has underperformed the sector today by 1.05%, and its delivery volume has significantly dropped by 54.29% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has declined by 3.71%, while it has shown a modest increase of 3.91% over the past month. Despite a healthy long-term growth in net sales at an annual rate of 33.30%, the company faces challenges such as poor management efficiency, evidenced by a low return on capital employed (ROCE) of 8.32%, which suggests low profitability relative to its capital. Additionally, institutional investors have reduced their stake by 2.19%, indicating a lack of confidence from more knowledgeable market participants.
In the broader market context, the Sensex has increased by 1.58% over the past week, contrasting with Epack Durable's decline, which highlights the stock's underperformance relative to the benchmark. While the stock has generated a return of 3.68% over the past year, it has lagged behind the Sensex's 5.43% year-to-date return. The company's expensive valuation, with a PEG ratio of 1.1, further complicates its attractiveness to investors, especially in light of the declining participation from institutional investors who typically have better analytical capabilities. Overall, these factors contribute to the stock's recent downward movement.
